Ten former NASA astronauts were Interviewed t o provide Information f o r use
In planning f u t u r e space f l i g h t missions.

Although no s t a t i s t i c a l analysis of

t h e material was performed, t h e responses do provide Insight Into numerous
aspects of space f l i g h t . Including psychological aspects, t r a i n i n g , command
s t r u c t u r e , health and comfort, physical aspects, and many o t h e r s .

The

responses by t h e Astronauts t o t h e questions a r e presented together with
coRTients by t h e researcher, himself a physician with long experience with the
space program.

Additionally, spontaneous matters t h a t came up 1n t h e

questioning periods a r e reported upon together with t h e r e s e a r c h e r ' s comments
on t h e s e a s w e l l .

The r e s u l t s , which maintain the s t r i c t c o n f i d e n t i a l i t y of

the Individual respondents, contribute t o t h e basic Information required by
those planning f u t u r e missions In space.
INTRODUCTION
This I s a report of information obtained during t h e course of separate
Interviews with ten former NASA astronauts t h a t took place during t h e f i r s t
half of 1984.

The purpose of t h e Interviews was t o e l i c i t Information t h a t

had not been previously reported and t h a t might open leads f o r f r u i t f u l
research endeavors applicable t o the United S t a t e s Space Station program.
There a r e many reasons why t h i s Information might not have been reported.
I t might have been forgotten during the Astronaut's p o s t - f l i g h t debriefing, o r
he might not have f e l t t h a t i t was Important a t t h a t time.

There may have

been personal reasons why he did not care t o mention some Items.

Some

material may have developed in h i s mind as a r e s u l t of r e f l e c t i o n s since h i s
f l i g h t and of h i s observations of f l i g h t a c t i v i t y t h a t have occurred since h i s
own mission.
Every e f f o r t has been made t o safeguard t h e c o n f i d e n t i a l i t y of t h e
inquiry, a s described in t h e section on c o n f i d e n t i a l i t y .

1

�METHOD
A 11st of fifty-one questions (Appendix A) was formulated by the
Investigator.

Published documents, discussions with NASA personnel, and the

Investigator's own personal knowledge of space f l i g h t human factors entered
Into the formulation of the questions.

Some changes were made In the l i s t of

questions as Insights were gained during the course of the Interviews.
The original thought was that each subject would be asked each question on
the l i s t , but I t soon became apparent that t h i s approach would not be the best
way t o proceed.

Some of the questions clearly referred t o specific programs.

Project ApoUo for example, and would be of l i t t l e use in Interviewing a
person whose experience was restricted t o an e a r l i e r program.

Further, I t was

seen that s t r i c t adherence t o the l i s t of questions would result In s t i l t e d ,
stereotyped replies - the questions became boring rather than stimulating.
After the f i r s t two o r three Interviews, I t was decided t o use the questions
only t o stimulate discussion.

Although some questions were given t o a l l ten

contacts, some were only given t o one or two. with each question being
presented t o an average of 6.2 contacts.

This I s somewhat misleading because

In certain Instances questions would stimulate answers t o l a t e r questions, and
the responses were combined.

(See Question 4)

Ames Research Center provided the Investigator with a l e t t e r of
Introduction (Appendix B), which described the program and I t s goals, and
which reviewed the background of the Investigator. The l e t t e r gave absolute
assurance that the Information given would be safeguarded In such a manner
that no statement could be attributed e i t h e r t o an Individual o r t o his
specific f l i g h t .
The contacts were each paid a consultant's fee of $50.00 per hour.
I t was originally Intended for Mr. Donald K. Slayton t o be present a t each
Interview so as t o take advantage of his background, training, and knowledge
of manned space f l i g h t operations.

I t proved nearly Impossible t o coordinate

the schedules of the Investigator, of Mr. Slayton, and of the contacts.

2

�without delaying the progress of the project to an unacceptable degree; Hr.
Slayton, therefore, was present during only two of the interviews.
The first interviews were with people known personally to the investigator
or to Hr. Slayton (or both).

These individuals made suggestions for

subsequent interviews.
MECHANICS
The contacts were first called by telephone and the purpose of the study
was explained to them.

If they consented to being interviewed (and some

declined because of their busy schedules), an appointment was made, and a copy
of the letter of introduction was mailed to them in sufficient time to allow
them to review it before the interview.
Because of the preconceived opinion of the investigator that the presence
of a tape recorder would be inhibitory to the free flow of information, the
original plan specifically excluded the taping of the interviews.

When the

first individual was contacted, and when it was explained to him that a tape
recorder would not be used, he said he felt the taking of handwritten notes
would be distracting to him.

He then asked that a recorder be used in his

reluctance to being taped.

None expressed even the slightest

One even asked for a copy of the tape for his

children.
In all cases the investigator traveled to the community where the contact
lived.

The interviews took place in the contact's office on three occasions,

in his home on three occasions, and in the investigator's hotel room on four
occasions.
The environment was very informal.

question was selected and asked.

As stated earlier, the questions were

When the conversation lagged, another
This usually resulted in a great deal more

spontaneous conversation.

�SAFEGUARDING CONFIDENTIALITY

Each contact was assured at the time of the initial telephone conversation
that anything he said would not be traceable to him or to his flight.

The

letter of Introduction contained these same assurances, and they were repeated
in the investigator's letter that forwarded the NASA letter of Introduction.
Finally, the subject was given the same assurances orally at the time of the
Interview.

It was apparent that most of them appreciated the assurances of

confidentiality and were probably more open In their discussions as a result
of those assurances.
After each Interview the tapes (12 In all) were brought back to the
Investigator's residence, where they have remained stored In a safe location.
They are identified only with a numerical code number.

Paraphrasing was rarely used and then

only when It became necessary to clarify syntax that was peculiar to the oral
Interview situation.

There are a few portions of the tape that have not been

transcribed because they referred to the personal social relationships of the
contact and the Investigator.

�GENERAL FINDINGS
The subjects were, without exception, extremely cooperative.
towards the investigator or the project was expressed.

No animosity

The investigator could

detect no evidence of conscious withholding of information.
A broad range of experienced people were interviewed, including persons
who had flown on all NASA programs, with the exception of the Space Shuttle.
Interviews were conducted with crew members from Mercury, Gemini, Apollo, and
Stcylab.

The Apollo contacts included men who had participated in the

Earth-orbiting phase of the project, and in the lunar landing phase.

One of

these latter contacts landed on the moon and another was a Command Module
Pilot who remained in lunar orbit alone during a lunar landing mission.
No meaningful statistical evaluation can be made for several reasons:
1.

The list of questions was not rigidly adhered to.

All subjects were

not asked all questions.
2.

Answers to questions were subjective in nature.

3.

Many spontaneous questions generated by the subject's comments evolved

on the spot.
interviews.

Some of these were not really applicable to subsequent
On the other hand, some of these spontaneously generated

questions were asked at subsequent interviews, but no effort was made to
contact earlier subjects to ask them to answer the newly generated questions.
4.

Only ten people were interviewed.

In this report the questions will be stated, and in cases where the
question was presented to several individuals, an evaluation of the replies
will be attempted.
Spontaneous statements of importance and answers to spontaneously
generated questions are included at the end of the answers to the list of
fifty-one questions.
NOTE:

After the answers to each question, there is a section labeled

"COMMENTS'.

This section contains the investigator's own subjective remarks

�and evaluation of the statements made by the contacts.

A COMMENTS section

the prepared questions.
ANSWERS TO PREPARED QUESTIONS
1.

Opinion of the Crew Health Stabilization Program.
Surprisingly, only 2 of 9 who were asked this question were opposed to the

program.

All stated either spontaneously (5) or upon questioning (2) that

they thought It was helpful In keeping the crews Insulated from annoying
contacts.
•1 thought 1t was kind of fun.

It kept the world away from us."

•It allows the crews to concentrate on what It Is they have to think
about.

It allows them to focus on the task and the training ahead."

CoiMents;

Inasmuch as the Crew Health Stabilization Program is no longer

practiced with as much rigidity as It was In the early Apollo flights, 1t
might be wise to develop some policy for providing a similar degree of privacy
and seclusion for future missions.
2.

Thoughts on Space Station maintenance activities.

NOTE:

Because of the similarity of responses to this question and Question 4

regarding tools, the responses to both questions have been cond&gt;1ned here.
This question was presented to all the contacts.

Two had no comments on

the subject.
One man said that multipurpose tools were Important.
Inclusion of files, wrenches, and other common tools.
Swiss Army knife was especially valuable.

He urged the

small parts to the workbench surface when making repairs.

6

�One man commented that the Apo11o tool kit was very good.
Another urged that maintenance should be kept simple - at the 'black box'
level.
One respondent thought that neutral buoyancy training was good practice
for maintenance, but another stated that it was misleading at best.

He urged

that any procedures developed in a neutral buoyancy tank be checked out in the
zero-g aircraft before being adopted for use in space flight.
Only one person mentioned the importance of foot restraints.
One recommendation was to project maintenance instructions, and even
diagrams, on the inside of the helmet visor in the manner of a Head-Up Display
(HUD).
A quotation from one of the contacts might prove interesting:
•You design things for routine maintenance done there by people with tools
in order to keep the system simple, and with simplicity you gain reliability.
You get the reliability through that route rather than through redundancy and
automation."
Comments:

The most significant response to this question is contained in the'

last quotation.

The recent remarkable successes in satellite recovery

operations add emphasis to the quotation.

Future satellites and future Space

Station equipment should be developed with the plan in mind that crew members
are capable of performing routine bench-level maintenance.
3.

Alarm Systems.
This question was presented to seven contacts.

Two of them mentioned that

they noticed a decrease in the loudness of sounds somewhat proportional to the
reduction of pressure in the helmet.

audible alarms should be a "warble t o n e ' a s i s used by some European police

Two individuals mentioned t h e g r e a t importance of e l i m i n a t i n g f a l s e
alarms. One suggested t h a t a study of t h e c h a r a c t e r i s t i c s of f a l s e alarms
might reveal a "signature" f o r f a l s e alarms.

Comments:

The suggestion t o i n v e s t i g a t e t h e " s i g n a t u r e s ' of f a l s e alarms

might be worthy of f u r t h e r i n v e s t i g a t i o n .

None.

Food and meals.
Of t h e ten persons Interviewed, one had no cormnent; t h r e e suggested t h a t

meals be s elected from a menu i n - f l i g h t ; and f i v e advised t h a t a l l individuals
e a t t h e same thing a t each meal with no s e l e c t i o n .

Hention was made by these

individuals t h a t t h e m i l i t a r y chow l i n e had much t o reconmend i t . One of the
f i v e suggested t h a t snack Items be provided f o r f r e e s e l e c t i o n from a pantry,
but he s t i l l did not recommend t h a t t h e r e be Item s e l e c t i o n f o r t h e main meals.
One person said he f e l t a menu determined ahead of time by crew interviews
was of l i t t l e value because people lose some of t h e i r a b i l i t y t o t a s t e when in
zero-g.

He s a i d t h i s could be helped by providing strong condiments -

pepper i n o i l s o l u t i o n , hot mustard, and s o f o r t h .

�One contact suggested the Investigation of foil-packaged foods that are
marketed under the brand name of RETORT FOODS.

These are not freeze dried,

and may be eaten hot or cold.
One contact urged that more attention be paid to the nutritional aspects
of the diet.

He distinguished between those aspects of food preparation that

are conventionally performed by a dietician and those performed by a
nutritionist.

He suggested NASA pay more attention to the latter aspects of

menu and diet selection.
Comments;

Those who advocated the military chow-line approach have probably

not seen today's chow line.

In present-day military dining halls, there is a

remarkably broad selection of items available.

One of the contacts suggested

that each crew member be asked about his dislikes rather than his likes.
disliked foods would not be provided in his menu.

The

This seems like a

reasonable approach.
6.

Trash disposal.
This question did not stimulate much discussion in the early interviews so

was eliminated later on.

Two subjects suggested that trash be pyrolized -

convert trash to energy.

Two others who were asked had no comment.

Five were

not asked.
Comments;
7.

None.

Clothing design.
The overwhelming opinion was for a two-piece garment with lots of pockets

(seven out of nine, with two "No Comments").

The advantage of being able to

shed the upper garment for comfort in warm areas was comnented on twice.

All

agreed that many pockets were a necessity, but pocket closure should be with
Velcro rather than with buttons, which could catch on things.

Two unusual

comments included the suggestion that a "dress" uniform be provided for
special occasions- this for morale purposes.
colors and styles was important for morale.

Another was that a variety of
One individual stated the need

�for strict dress-code enforcenient as an aid to maintaining discipline.

One

subject stated he had had some experience with polypropylene outdoor clothing
and thought it might be worthwhile investigating.

He said it was quite

comfortable, but brought up the question of its fire resistance.
One suggested a different garment for wear during exercise periods.
One man suggested that two-piece uniforms have some means of fastening the
shirt/jacket to the waist of the trousers to prevent uncomfortable gapping at
that point.

He suggested Velcro.

There was a need expressed for a place to carry an emergency checklist at
all times.
Free choice of underwear was suggested.
One man suggested that slippers be provided for off-duty wear.
Coweents:

As might be expected, there was a wide range of suggestions

regarding clothing.

When some of the more extreme suggestions are eliminated

one reaches the conclusion that the basic in-flight uniform should be a
two-piece garment with many pockets.

The suggestion for the provision of a

place to keep an emergency checklist available at all times is a good one.
B.

Personal hygiene equipment.
Three contacts had no comments, and three were not asked.

The remainder

had comments that did not fit any pattern:
One wanted to use an electric toothbrush and an electric razor.

Another

preferred manual toothbrushes and a blade razor.
One man said that all on board should use whatever turned out to be
'issue' equipment.

He also mentioned that he would insist on daily shaving as

I d e n t i f i c a t i o n of "Up" and "Down".
Because of t h e s pecial i n t e r e s t of t h i s question, a g r e a t deal of time was

spent on i t .

Of t h e t e n subjects questioned, nine were very d e f i n i t e in

s t a t i n g t h a t t h e r e was no need t o t a k e any p a r t i c u l a r pains t o i d e n t i f y up and

Several commented t h a t down was always where t h e i r f e e t were.

There

appeared t o be no d i f f e r e n c e between t h e answers from individuals who had
flown in confined spacecraft and answers from those who had flown in spacious

11

�vehicles.

One Individual said he himself was not bothered by the lack of up

and down, but stated he f e l t I t would be wise t o ensure t h a t everything In a
given volume have the same orientation.
One contact related that one of his colleagues had spent "hours and hours'
In the simulator, then went Into f l i g h t and became 111 even before he had
gotten out of the s eat . The point of t h i s observation I s t h a t t h i s person had
excellent up and down references but became 111 anyway.
In response t o a direct question, one man said t h a t even seeing his
colleagues In an orientation different from his own did not disturb him.
Two men conmented that the use of a simulator may drive the configuration
of the Space Station, a t least In areas where simulator training 1s
extensive.

The simulator will have t o be constructed with an up and down

orientation because I t I s used In a one-g f i e l d .

The Space Station area must

match the simulator for training If I t I s t o serve any purpose.
The following quotations are presented:
(1)

'Before I came Into the space program I tended t o have a great amount

of familiarity with mathematical techniques of rotation and translation of
axes systems...! tended t o look a t something and j u s t figure t h a t I had a
rotated coordinate system.

(In space) I ' d look out a t the Earth, and I ' d

recognize the Earth had I t s own set of Earth-centered coordinates.

The

spacecraft had I t s space-centered coordinates. Whenever I saw the two In the
same field of view 1 just automatically thought of the spacecraft as being
oriented t o the Earth, but more Importantly, I had my own body-centered
coordinates, and the Input, If somebody allows them t o , can be of those
things. . . . I f you operate 1n egocentric coordinates "down" will be towards
your f e e t .

I t makes no difference whether you're going over the Earth upside

down o r diving under I t , or any of those things, If you really look a t I t as
your world Is where you are, and everything else I s oriented around you."
(2)

One contact said he thought I t fun t o look a t the world upside down.

"Trying t o force a one-gravity mode of operation Into zero-gravity I s a
mistake.

I t defeats a l l of the freedom which you a r e given."

When he would go from one compartment t o another, one person s a i d ,

" I think we adapt e a s i l y t o most any environment, but I j u s t d o n ' t think
there i s a g r e a t deal t o be gained by t r y i n g t o force people t o think as they
do here on Earth when they a r e , i n f a c t , in space."
Comments:

If t h e opinions of t h i s small sample of people a r e f e l t t o be

s i g n i f i c a n t one must conclude t h a t special e f f o r t s t o i d e n t i f y "up" and "down"

On t h e other hand, none of t h e ten subjects interviewed admitted t o having
experienced any degree of nausea.

If none of t h e ten contacts became i l l , and

From t h e obvious s i n c e r i t y and d i r e c t n e s s of t h e s e ten contacts, I am

convinced t h a t none of them became i l l .

This, I must admit, i s a very

subjective assessment, but i t i s my conviction t h a t they were a l l t r u t h f u l and

Importance of private cwnnunlcatlons.
This question was asked of all ten Individuals.

Responses varied from,

'Hot all that Important' to 'Absolutelyl'
Host of the respondents thought a private line was Important for personal
connunlcatlon with families, but of equal Importance was Its use In
operational control of the flight.

One subject gave an example of a situation

In which Instructions had to be paraphrased to keep them from being heard by
the press.

The paraphrased Instruction was misinterpreted to be a Joke and

was not followed.

The example cannot be further Identified or described here

as it would reveal the source, but suffice It to say that the well-being of a
crew member was Jeopardized by this misunderstanding.
One contact said, 'The Administrator [NASA] doesn't have a microphone In

How to manage books and manuals.
This question was presented to only four of the ten contacts.

One stated

he preferred books, but could learn to live with Information presented on
CRTs.

One contact had no comments, and the other two said that they did not

think that everything had to be In data banks.

Some material can best be

presented in book form, and other material can be stored In data banks for
retrieval when needed.
The feeling seemed to be that recreational material was best presented In
book form, but technical material (with the exception of emergency checklists)
could be stored In data banks.

Han/machine interface.
This question was put to five of the ten contacts.
One suggested that color be used more in the design of the Space Station,

and one said color was not a11 that important.

One had no comment.

One man suggested that NASA employ what he called "functional artists" to
help in designing the interior of the Space Station.

He stated that the

wardroom should be of a "relaxing* color and the flight deck should be of an
"alerting" color.
One individual urged caution in accepting the use of digital displays.

He

said:
"Digital offers various advantages in terms of accuracy, precision when
you need precision, but the human being is an integrator, he doesn't take
snapshots, and there is a lot of information and intelligence lost when you're
looking at a digital display."
Comments:

The science of architecture is advancing at a great pace.

NASA

would be well advised to use the services of this discipline in establishing
interior design criteria for the Space Station.
I was impressed by the warning about digital displays.

From a purely

personal standpoint I find it easier to integrate analog informational
displays than I do digital displays, but this may be purely cultural.

An

interesting area for investigation would be to assess whether people get more
or less information from one display than the other.

Unquestionably, it is

easier and quicker to read, for example, the exact time from a digital
display, but does one find it also easier to tell how many minutes have
elapsed since a given event or how much time remains before a given action
must be taken. I am sure similar analyses could be made of altimeters, and
other displays of changing quantifiable information.

I am in agreement with the contact who stated that the provision of

artificial gravity negates one of the more Important reasons for being there.
Of course, it Is self-evident that If an overwhelming medical or physiological
need arises for artificial gravity. It must be provided, but lacking that, I
can see no justification for It.

The concept that the provision of artificial

gravity would eliminate the need for exercise and thus be an economically

A considerably milder comment was made by another contact who said that a
clear chain of command was needed but, "...you don't need a man beating his
chest."
The nearly opposite view was expressed by a contact who said:
"Yog know the stereotype of Marine Drill Instructor - you don't need those
kinds of abilities up there - you need people with a broad perspective; people
who are interested in enough different things outside their own area of
expertise. I think that would be especially apropos of the Commander of the
mission."

He went on to say, "When you go to autonomy in space and you have

your scientists up there [there are going to be conflicts which the Commander
will have to solve].

You have to be able to compromise, and accommodate all

those kinds of things.

The Commander will have to be real diplomat."

Another contact recommended a strong authoritative Commander, but he has
to be the kind of person who knows how to lead, and "...just to give an order
is not the best way to lead."

But, he said, there also has to be a strong

connand structure.
One man who stated there must be a chain of command suggested that there
night possibly be a Commander for each shift with interaction between them.
He said that the Commander should be not be resistant or blind to suggestion
and inputs from the rest of the crew.

When asked if he would recommend a

military hierarchial system, he replied that he would prefer a NASA
hierarchial system, which he said is not as rigid as the military system.
Another contact also recommended a dual command system, but constructed
around different lines.

between the Captain of a carrier and his Air Sroup Commander.

The contact

stated that the ultimate responsibility must be assigned to one person.
said, 'You cannot have a voting situation up there."
NOTE:

He

The term "Hilltary Commander" as used above was not meant by the

speaker to imply that he advocated the Space Station be conuianded by a DOD
representative.
Conments:

He used it as a figure of speech.

Most of the respondents focused on the role that the Conmander must

play, and how he must act in exercising that role.

One contact really caught

the significant part of the question and stated that even more important than
the Commander's actions was the need for a strong comaand structure.

It has

been my observation that some Military Commanders get the job done by virtue
of the fact that their subordinates are afraid of them; others because they
are respected:and others because they are idolized.

Regardless of the

Commander's attitude, the job always gets done unless the conmand structure
breaks down.

Even the autocratic Commander gets the job done unless he

attempts to dissolve the command structure.

When he does that, the

organization falls apart and the mission is a failure.

How Hi-Fi should the Space Station simulator be?
This question was given to five people.

Only one recownended that the

simulator have as much fidelity as possible recognizing the limits imposed by
gravity.

Two men felt that a complete simulator, a duplicate Space Station, was not
needed.

Part-task and modular simulation should be adequate.

These were

thought to be especially valuable devices for problem solving.
one man suggested that the Space Station control room should be fairly
well simulated, but the other functions of a Space Station need not be

36

�duplicated on the ground.

He suggested a minimum ground training period and

conpletion of training In the Space Station itself under the supervision of
the crew.

He presupposed that only part of the crew, perhaps two out of ten,

would be replaced at any one time.
One man had no comments.
Conments:

The suggestion that part-task and modular simulations should be

adequate seems to be a reasonable approach.

The concept of training after

arriving on station is an interesting one and might be an area for
investigation.
49.

Accommodating diverse groups of people.
Seven people were asked this question.

Two people expressed disapproval

of the concept of taking the "man on the street".

Both of these contacts felt

that, in the foreseeable future, we would be taking selected people.

One

mentioned that we would select them first for their skills, second for their
motivation, and third for their physical and mental health.
mentioned construction workers.

One contact

He thought we would ask for volunteers from

the population of construction workers, then we would select the most skilled
and the most fit.
Three contacts mentioned their opposition to the practice of applying
arbitary age limits.

They felt that the results of a physical examination

should determine a person's fitness to fly, not his age.

One mentioned a Dr.

Vincent in Houston who has a program that is an excellent predictor of mental
acuity.

The respondent thought some of the airlines were using Or. Vincent's

technique.
One stated that we could markedly relax our physical requirements because
there are no stresses in space.
Another felt that most of the problems will be societal, and the Commander
will have to deal with them.

SPONTANEOUS COMMENTS
As stated in t h e s e c t i o n e n t i t l e d METHOD, t h e 51 questions were a c t u a l l y
used only t o s t i m u l a t e d i s c u s s i o n .

Although a g r e a t many comments were

received in response t o t h o s e q u e s t i o n s , t h e r e were some additional statements
•ade either spontaneously o r a s a r e s u l t of thoughts stimulated by t h e
questions.

Some of t h e s e spontaneous statements a r e presented in t h i s s e c t i o n .

1. I t had been several y e a r s , and even decades, since some of t h e contacts
had flown.

One of them opened t h e interview with t h i s statement:

" I t i s i n t e r e s t i n g your coming around doing t h i s .

I commented t o [ h i s

wife] t h i s morning t h a t t h i s i s t h e f i r s t time anybody has asked my opinion
about anything s i n c e t h e day I l e f t NASA.

And, consequently, i t i s of a l o t

less value than i t might have been a year a f t e r I l e f t NASA."
Conments:

In l i g h t of t h e remark made by one c o n t a c t t h a t h i s remarks might

have had more value had he been contacted a year a f t e r leaving t h e program
rather than several years l a t e r might suggest t h a t NASA give consideration t o
establishing a procedure whereby a l l former a s t r o n a u t s would be interviewed a
year or two a f t e r they leave t h e program.

1 f e e l confident t h a t individuals

who are no longer competing f o r a f l i g h t p o s i t i o n , o r who a r e no longer hoping
for advancement i n , o r rewards from, t h e system might well be a very valuable
source of information.

Among t h e t e n people I interviewed, 1 f e l t t h a t some

of there were so long out of t h e program a s t o be of l i t t l e value t o t h i s
project.

On t h e o t h e r hand, some who were more r e c e n t menders of NASA had

•any good conments which t h e y probably would not have made had they been
corepeting f o r f l i g h t assignment.

One stated that he feU gymnastics might be a good training procedure,

particularly use of the trampoline, in combatting space motion sickness.
Cowwents;

3.

None.

In view of the fact that EVA astronauts do not appear to use their legs

very much, one contact was asked his opinion regarding a suit without separate
legs. He replied;
•Some of the EVA tasks would require that you anchor your feet somehow,
because that's the way you apply the torque.

If. of course, you have some

umbilical 'belly-button' kind of thing with which you attach yourself rigidly
through your center of gravity, then you could obviously use your arms pretty
well without a foot restraint.

I would kind of think that having your legs

separate would give you much better torque and muscle control."
In response to the same question another contact said•But If you're thinking In terms of a Space Station where you're going to
have to do some manual work with your arms, and you look at the situation
Where you put In a torque motion. I don't know how you would counteract that
without having your feet somehow [stabilized],

speaking of construction work

1n space he said. "It Is In that kind of a mode where I would envision that
you might want [to use your legs].'
Comments:

4.

None.

When speaking of training, one contact mentioned what he called an

advocacy position In training,

it Is sitting down ahead of time and asking

what^one will do If a certain event takes place.

He said:

•Within certain limitations you could take the advocacy role ahead of
time.

It's a 'brain-washing', and I know that's a bad word, but you train to

the point where, when you get there, the actual case Is a piece of cake.
many times It doesn't have to be a hands-on kind of training.

And

You can sit In

a room and discuss what we're going to do If this happens and why do that
one.

But you gotta go through that exercise.

42

It's a very Important part of

�getting ready t o go."

The contact then gave two examples from h i s f l i g h t

where f a m i l i a r i t y with the system and procedures saved t h e mission.
Cofiments;

The remarks regarding "advocacy" t r a i n i n g were i n t e r e s t i n g t o me.

The mental exercise of s i t t i n g q u i e t l y alone o r with o n e ' s colleagues and
contemplating possible events and how t o cope with them I s probably an
excellent way t o t r a i n f o r foreseeable e v e n t u a l i t i e s .

Perhaps such t r a i n i n g

methods could be encouraged.
5.

At the close of h i s interview, one contact offered t h e following

independent thought:
"One of t h e t h i n g s I d o n ' t think we're doing t o o w e l l . . . i s designing
things l i k e t h e Space S t a t i o n , taking advantage of t h e r eal and unique

When asked f o r examples he said t h a t he had

none a t t h e moment.

Another contact i n explaining why he thought he did not g e t motion

He continued t o cowaent that performing r o l l s In a zero-g parabola and
holding the head in different positions a t the same time was the most
efficient way of producing nystagmus that he knows.

He got t o the point where

he could make the world 'twitch* in any direction depending upon how he held
his head during the r o l l .
£ommsntsj_

NASA might give some thought t o investigating t h e training routine

described by the contact who stated he and his partner executed 15 t o 23 rolls
while in a zero-g parabola, with t h e i r heads in a d i f f e r e n t orientation for
each parabola.

I am astounded a t the piloting s k i l l which t h i s maneuver

requires, but if i t can be done I t might be of value i n anti-motion sickness

He said

that i t might be necessary t o bring up one o r two s p e c i a l i s t s for short
periods t o perform specific tasks, but he f e l t i t was important t o change the

Another Interesting concluding remark was:
"There i s one other thing I always make a pitch on. and t h a t i s that they

do not realize that people in space f l i g h t o r in zero-gravity condition are no
different than down here.

You have zero gravity and a b e t t e r view, but other

than that you are dealing with the same person and the same working

So far, the way space

Coninents;

See comments following Statement 9.

Another man expressed the same thoughts in this way:
"My big 'soap box' effort is the thing about let's not forget who we are

and what our needs are as people, and carry those things with us.

Let's not

lull ourselves into thinking that this is such a special environment that all
the rules change and everything is different, and that people will give up
this and give up that In order to be up there.

They will do it for a ten-day

mission, but they won't do it for ninety days."
He went on to say, "One of the problems we ran into on our mission was
that we forgot to think about those things, and we got ourselves caught up in
a workaday thing where we were working fourteen to sixteen hours a day, and
working strictly following a carrot - following a very precise agenda every
day.

Halfway through the mission we began to get inefficient and made

mistakes.

Me finally recognized our problem and did something about it, and

came out at the end of the mission in good shape.

We finished everything we

were supposed to do and got it all right."
Comments: I commend the two remarks regarding utilization of people for their
capabilities and their human abilities to NASA for serious consideration. I
agree with both comments.

If we are to put people in space we must take

advantage of their capabilities and their "humanness", whatever that is.

He

should recognize the tendency to overschedule and actively correct for that
tendency.
10.

One contact believes that the absence of low-frequency electromagnetic

radiation in space might have some physiological consequences.
this radiation is commonly referred to as Schumann resonance.
this subject he said:

45

He said that
Speaking to

�•W1th1n the Ionosphere-Earth surface cavity there is, I think, about an
8-H2

to 32-Hz oscillating field with a series of peaks in that field that is

generated by lightning storms on Earth, but the net result of all that
electromagnetic activity is that we're exposed from conception to death to
this oscillating field, and there is some evidence that if you play with that
field here on Earth, particularly by superimposing a 5-Hz, 4-Hz, or 3-Hz field
on what is already there (and it is very difficult to isolate the individual
from it unless you go underground) and you get some neurological problems.

It

does affect people, and it is probably related to what happens to you when you
get a relatively low-frequency strobe light flashing at you.

A lot of people

feel very very uncomfortable neurologically when that happens.
course, it's absent.

In space, of

Once you get above the ionosphere that field is absent,

and there is some concern among physicists who have a background in
neurophysiology that there might be an instantaneous effect contributing to
the Space Adaptation Syndrome, but they are more concerned about what the
long-term effect may be if the brain actually uses that frquency on occasion
or continuously to reset it's own timing signals in it's central processor.
So, 1 would FLAG that as an unknown."

This contact was also concerned about "intermittent sleep."
could cause difficulty from the standpoint of loss of REH sleep.
sleep is different from simple insomnia.

He felt it
Intermittent

Intermittent sleep is that situation

where a person wakes up and goes back to sleep several times during a sleep
period.

It should cause no problem over short periods, but if continued for

two months or so it might.

It has been noticed in sleep labs on the Earth,

but the contact was of the opinion that it occurs more frequently in space
flight than it does on the Earth.

Comments; I cannot connent on the role of low-frequency electromagnetic
radiation in space and its physiological consequences and I am unaware of
"Schumann Resonance", but I do want to underline this individual's connent as
a possible route of inquiry, which NASA might investigate.

I also am unable

to comment on this same contacts remarks regarding "Intermittent Sleep".

�Coimients; I believe this last remark regarding the unsatisfactory nature of
unrestrained or free-floating sleep has been made before, so It requires no
further Investigation, but should be kept In mind when sleep restraints In the
Space Station crew quarters are being designed.

Dear Space Missioa Participant:

The purpose of this letter is to introduce Dr« William K« Douglas and a
project that he is conducting under the sponsorship of NASA's Anes
Research Center.
The Ames Man-Vehicle Systems Research Division under its Space Human Fac­
tors Office is in the process of planning research that will help to as­
sure high levels of crew effectiveness on future space missions, including
NASA's proposed space station. Several expected differences between the
space station and previous missions suggest that such research is warrant­
ed. Such differences include more heterogeneity of crew members in back­
ground and experience, broader variety of work requirements (including
more EVA), larger crews, and longer durations.
To accommodate some of these changes, plans and designs are being
developed for configurations of the total station, individual modules, and
work stations, as well as for habitability Issues and operational pro­
cedures.
In many cases the appropriate design or plan for promoting and
maintaining effective crew performance under the changing conditions is
unknown. Numerous cases involving new designs for work stations and habi­
tats have been documented, in which serious performance problems have ar­
isen because of either the lack of human factors information or the
failure to incorporate available information.
The Division has been active for several years in research to support the
aviation community in developing methods for avoiding such errors in
design, and operations. One of the more valuable sources of Information
that has directed our research activities has been the Aviation Safety Re­
porting System (ASRS), which we direct (through a contract, under the
sponsorship of the FAA).
The system solicits voluntary comments and
recommendations from pilots and air traffic controllers that concern any
procedural problems encountered in the aviation system, and how these
might be corrected. The reports are completely deidentified to insure
anonymity of the reporter.
Publication of the obtained information is
generally in the form of a report that synthesises Individual comments and
recommendations related to some particular Issue.
Information such as that generated by the ASRS has proven of value, not
only by indicating problems that require research for their solution, but
by Indicating when research is unnecessary, either because Information is
available to effect a solution, research is already in progress, or the

57

�problem Is not amenable to research. When research has been prescribed,
the value of Its product has been enhanced significantly by the direction
received from such information.
The project being conducted by Dr. Douglas Is consistent with the intent
and spirit of the ASRS. We are convinced that the experience of partici­
pants in previous space missions can form the basis for cogent recommenda­
tions for design, operations, and appropriate research relevant to future
space missions, similarly to our experience in aviation.
Therefore, we
have asked Dr. Douglas to solicit thoughts regarding apace station design
and operational requirements. The information obtained will be used to
help us (and others) supply guidelines to designers, and to discover
inadequacies in available knowledge that Indicate a need for further
research.
Dr. Douglas has contacted you as part of that process.
Dr. Douglas was
the first flight surgeon for the Mercury astronauts. We sought his assis­
tance in this project because of his reputation for sensitivity, objec­
tivity, general knowledge of and appreciation for the human in space mis­
sions, and his acquaintance with many members of the astronaut corps.
We are requesting your participation because of our sincere interest in
helping to assure a high level of effectiveness for future manned space
missions. Dr. Douglas' approach will be informal.
He will ask you a
series of questions designed to focus your consideration of design and
operational Issues, which we judge are important to the success of future
missions.
In your answers to the questions we are asking you to project
from your experience to the expected conditions on a space station.
We are not interested in documenting or reporting problems, either person­
al or general, from past missions. Rather, we are asking for your judg­
ment of where impediments to task performance, motivation, morale, etc.
could arise; what changes in design and operations would you recommend,
based on your experience and expected mission differences.
Dr. Douglas will be assisted on the project by Mr. Donald K. (Deke) Slayton, whom you may know personally. Mr. Slayton's experience and knowledge
should be of great assistance to Dr. Douglas in interpreting and syn­
thesizing the information, and producing a useful report.
Please be assured, should you elect to participate, that the information
obtained by Dr. Douglas will be completely deidentified from you as the
source. Not only will your individual anonymity be assured with respect
to specific information that you volunteer, but the identity of those per­
sons interviewed will not be revealed by Dr. Douglas or Mr. Slayton.

Ten former NASA astonauts were Interviewed using a set of 51 questions
developed to encourage the contacts to discuss any thoughts, opinions, con­
clusions, or suggestions which might have evolved since they left the astronaut
program.
Strict confidentiality was maintained. The reader will not be able to
attribute any recorded remark to an individual person or to a particular mis­
sion.
At least one astronaut from each of the NASA manned space flight programs,
excluding the Space Transportation System (Shuttle), was Interviewed. The
report records the answers to the questions asked, spontaneous comments, and
the Investigator's oim personal evaluations of the material obtained. No
statistical analysis of the material was attempted.
The professional opinions of these ten experienced astronauts will be
of value to persons concerned with the design and operation of mannoH space
craft and manned space stations.

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

The significant role of the photographic process on Skylab can
be appreciated when one realizes that nearly one-half of the ex­
periments onboard utilize some form of photography to gather
their scientific data. The inherent advantages of returned photo­
graphic records, high information density and permanence,
justifies the effort involved with its launch, stowage, and return.
One of the more important aspects of Skylab photography is the
entirely new portion of the spectrum revealed to solar and stellar
astronomers. As shown on the chart below, the experiments of
Skylab embrace wavelengths from Hard X-Rays to the Thermal
Infrared. The areas of Vacuum Ultraviolet and X-Ray studies have
only become feasible through space research because the Earth's
atmosphere filters and scaners these wavelengths.

The camera systems aboard Skylab range from conventional
35mm cameras to exotic systems employing detraction gratings,
articulated mirrors, and photocathodes emitting photoelectrons
to be focused on film. Through the use of these systems and their
films the scope of the studies is extremely broad. They will
return information concerning subjects as varied as the intense
Sun to the faint Zodiacal Light, cloud formations to the mass of
the Universe, and the contamination around the spacecraft to the
contamination of our Earth's atmosphere and rivers.
The films to support these experiments vary from color interior
films, similar to those commercially available, to films highly
sensitive to Far Ultraviolet. The quantity of film involved is
revealed in the fact that there are in excess of 125,000 exposures
in the area of solar astronomy alone.

The Earth Resources Experiment Package is an integrated system of
s·:msors for earth observations. Detecting electromagnetic radiation,
either reflected or emitted in the Visible through Thermal Infrared wave·
lengths. These sensors provide high resolution data covering widespread
areas of the earth. This data is expected to yield information fundamental
to the use and conservation of our natural resources. Some of the major
d1sciplmes addressed are agriculture, geology, continental water resources,
ocean investigations, and atmospheric investigations.

film to levels consistent with require­
ments for acceptable photographic data.
These vaults vary in thickness from 0.5
to 3.4 inches, and the largest weighs
approximately 2250 pounds.
Four of the vaults are used to protect
Apollo Telescope Mount {ATM) solar
astronomy film. and the fifth (IJrgest)
is used to store corollary experiment,
general purpose, land operational films.
In addition, the largest vault contains a
passive humidity control system which

�Solar Observations
The Apollo Telescope Mount (ATM) serves as the painting base for
eight solar telescopes. These telescopic observations are primarily in
spectral ranges that are obscurecl by the Earth's atmosphere. The high
resolution provided through photographic techniques 1s expected to
greatly e)(pand our understanding of solar behavior and 1n the assessment
of Its impact on our environment. Skylab provides th� first opportunity

Stellar Observations
As with solar observations, stellar researc:h is being conduc:ted in the
Ultraviolet. Since these emissions are characteristic of "young" stars, it is
hoped that they will provide ,m,ght to the origins of the universe. Efforts
in mapping the universe have already shown that our galaxie is larger than
previously believed.
Comet Kohoutek presented Skylab with the opportunity to be the
first to.view what may be the key to the origins of our own solar system.
Comets are thought to be pr,moral matter, which in this case has been
sitting at the fringes of our solar system, unaffected by our sun, possibly
since ils beginning.

�At scheduled times and at other moments of opportunity the
Skylab astronauts use general purpose cameras and accessories to
record their performances of certain experiment tasks and to
document specific happenings and conditions. The 35mm and
70mm instruments were procured as slightly modified versions
of the commercially available units. The 16mm camera was
developed for NASA early in the space program.

16MM DATA ACQUISITION CAMERA SYSTEM
Unlike typical movie cameras, the
Skylab Data Acquisition Camera
provides the capability for selecting
independent shutter speeds and
framing rates. Its unique film
magazine and transport mechanism
was developed such that as one
film cassette becomes depleted, it
then serves as the take-up mechan­
ism for the next cassette, thus
saving premium space and weight.
The basic, portable camera is 6" x 3.75" x 2.4" in size and weighs
but 2.7 pounds, including a 140-foot film cassette. The DAG
system includes an additional assortment of lenses, remote cables,
and auxiliary lighting, mounting, and extension devices.
The primary application of the 16mm DAC system on Skylab
is directed toward the documentation of crew activities and tasks
of interest ,n crew motion studies, recording of scientific results
of experiments, and the generation of documentaries and demon­
strations covering both planned and unplanned crew activities.
Such tasks and activities include events as varied as preparing an
evening meal, performing a complex operation such as manipulat­
ing a unique foot-controlled maneuvering unit, or visual inspection
of the Skylab cluster during a fly-around. Over half of all experi­
ments requiring such photographic coverage further require the
DAG. A majority of the photography is performed using color
interior film (S0168 Ektachrome ); however, infrared film (3443)
is used to record the results of space manufacturing experiments,
and UV emulsion (103ao) is used during stellar observations.

35MM NIKON CAMERA SYSTEM .........................
The 35mm Camera System consists
of two motorized dnd three manu­
ally operated Nikon cameras. These
models are Nikon FTN 35mm re­
flex cameras, two having motorized
film advancement mechanisms. Ac­
CP.Ssory ;enses include a 55mm f/1.2
visible, a 55mm f/2 UV lens, and
an assortment of wide-angle through
telephoto attachments.
The Nikon cameras are used in
conjunction with approximately
one-third of the experiments requiring photographic records of
scientific data or documentary records of tr.� performances of
scheduled tasks. In addition, the cameras are used to obtain
photographs useful in studies of the Earth's ozone layers, the
horizon airglow in visible and UV light, and the skyglow caused by
sunlight reflections from interplanetary dust (Zodiacal Light).

General
Purpose
Camera ----Systems
70MM HASSELBLAD DATA CAMERA SYSTEM
Two Hasselblad Data Cameras,
slightly modified versions of the
commercial, electric model (500
EL). are used on Skylab. The
camera incorporates a qlass reseau
plate wltt&lt;.h is positioned immedi·
ately in front of the film plate.
This reseau plate causes a pattern
of precision crosses to be placed
on each photograph, which facili­
tates photogrammetric utilization
of the photography.
The Hasselblad cameras are used primarily by the astronauts for
handheld photography in support of Skylab's Earth Visual
Observation Program. This program permits the astronaut•
operator to be both sensor and data processor, in that he is free
to make real-time assessments relative to optimum data-gathering
at pre-selected sites, and to identify/pursue alternate sites or other
targets of opportunity. These targets may include such items as
cloud formations, vegetation patterns. water/air contaminants,
volcanic observations, deserts, African drought patterns, geology,
or even cultural patterns.
In addition, the cameras are used to document astronaut
activities and to obtain reference photographs of the Skylab
cluster as each crew departs.

TELEVISION SYSTEM
Two television systems are used frequently on Skylab for
viewing the Sun, the Earth, and a variety of localized internal and
external targets.
For Sun viewing it is possible to display on black and white TV
the information from five Apollo Telescope Mount (ATM) cameras
in various wavelengths. The display is monitored routinely by the
crew on two screens at the ATM Control and Display Console.
The display can also be downlinked to scientists on the ground as
a check on the ATM instruments.
A color TV camera on Skylab generates a color signal using a
single tube with a tricolor, rotating filter wheel. Its output
characteristics are compatible with commercial television. The
camera can be fixed-mounted on the optical viewfinder/tracking
system used by the crew to view the Earth, as seen by the Earth
Resources experiments or mounted in various locations by the
crew to televise Extra Vehicular Activities (EVAs) and onboard
events, such as meal preparation and eating, science demonstra­
tions, and press conferences. A black and white monitor is
mounted on the camera to assist in aiming, focusing, and adjusting
the light level.
Television is broadcast in real-time or recorded on video tape
for later transmission to the ground. In either case, it is down­
linked only over selected ground stations.

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

                  <text>Skylab was the first space station operated by NASA; it was launched without a crew on May 14, 1973. Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;

Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns.&#13;
&#13;
Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions.&#13;
&#13;
Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.&#13;
