KERWIN  Unusual  or Unexpected Visual Phenomenon.  We  saw light  flashes.
 (CONT'D)
  I think  all  of us  saw them.  I  saw them most  often when  I was

  in the  sack  at night with my eyes  closed but  awake naturally.

  They tended to wax and wane  in  frequency.  Someone  asked me  if

  that  was  in  conjunction with the  South Atlantic  anomaly.  It

  may have been.  I didn't have the pad with me at that time and
  I don't know.  They were numerous  at times  - two or three per

  minute.

CONRAD  Some  of them to me were  a spot  or sunbursts.  Some were  streaks.

  The  streaks,  in my case, were  less  frequent  than the bursts.

  Most  of them were  in  my peripheral visual  field.  Very  few in

  the  central visual  field.  I  don't know why.

QUERY  You could isolate  them to  one  eye,  couldn't  you?

KERWIN  No,  I  couldn't.

WEITZ  I would say mine  were  primarily in the  left  eye  for  some

  reason.

JONRAD  You have to  concentrate but  you can  determine  they  are  in  one

  eye.

<ERWIN  Idid not.  That  was  foolish  of me but  I  didn't  try.  I'm sure

  they are  in  one  eye.

  23-20
CONRAD  Sometimes  I'd be lying there with my eyes half closed,  and I'd

  see  a fire  sensor wink.

KERWIN  And you'd have to be  careful that you weren't  confusing that

  with the  fire  flash.  Once you've  seen a few of each,  there  is

  question  of which  is which.  They're not  an hallucination.

KERWIN  We didn't  feel it was  operationally necessary for anybody to

  know  about  it  right  now.

WEITZ  I had  a couple that  I  thought were  cosmic  particles.  I  saw

  an  entrance  streak  and  an  exit  streak.

CONRAD  Yes,  I  did too.

WEITZ  Where, bing-bing,  it  seemed like  it was  one  side  of the  eyeball,

  and then  the  other  side.

CONRAD  One night  I  remember that there was  a long shot then it was

  blank then there was  a long shot  in  rapid succession,  of

  course,  but  very  definitely in  and out - or  across  the  eye.

KERWIN  Medical Kits  and IMSS.  As  far  as  adequate quantity of medica-

  tion  and supplies,  I would guess we  used about  0.01 percent

  of the  available medication.  I think this  is  something  for

  me  to  sit  down with the  doctors  and talk  about.  There  is

  plenty  of medicine  up there  for the  Skylab  missons.  There  is

BEAN  I  did too.  The  sack would move  over in the  corner.

LOUSMA  Things we  saw out the window.

GARRIOTT  For  example, we  saw that  satellite about  a week before  splash-

  down.  That was  one of the most unusual things  that we  saw

  and  I  guess  Jack noticed it  looking  out  the window.  This

  bright  reddish  object was  out  there  and we tracked it  for

  about  5  or  10 minutes.  It was  obviously  a satellite  in  a very

  Similar  orbit to  our own.  It was  rotating and had  a period

  of almost  exactly 10 seconds because you could see the
  bright-

  ness  vary with  that  period.  We  followed  it  until  sunset  and

  it went out  of sunlight  just  about  5 to 7 seconds  after we

  did.  It  held its  position nearly the  same,  in the wardroom

  window for that  10-minute  interval  although we  could  see  it

  drift  in relative positions  slightly, maybe 10 to  - 20  degrees

  during the  course  of that  10-minute  interval.  It was  reddish

  in  color  even when we were well  above the horizon.  As we

  approached  sunset,  it  turned more  reddish,  presumably because

  of the  sunlight  change.  What  satellite  it  was  and how it

  happened to end up  in  such  a similar  orbit,  no one ever explained

  to  us.  And  I would like to hear  a few words  from  someone  about

  that  satellite.
BEAN  You bet.  We never saw it again.  You'd think we would have

  seen it the next night or it would cycle by another time.

  Maybe it did and we weren't looking out the window.

LOUSMA  You might point out that it never did take the shape of an

  object but it was always brighter than any other star or

  planet in the night sky.  It was much brighter.

BEAN  We tried monitors and everything on it but we could never

  make it into anything other than a bright light.

LOUSMA  In doing TO02, I had on other occasions, at least once or

  twice, seen other satellites although they appeared as star

  points  of light.

BEAN  Let's talk about caution/warnings at night and in the daytime.

  I noticed at first when we did have caution/warnings in the

  daytime we all whistled up there real quick to see what was

  happening.  Then as the mission wore on, we tended to just let

  whoever was closest take a look.  Without the TACS on, there

  isn't a lot that can go on except rapid DELTA-P which sounds

  different than any of the other caution/warnings, particularly

  just a caution.  I recommend to Jerry and his crew, and I'm

  sure that this recommendation will be hard to live by, that

  caution/warnings don't appear to be anything you have to hurry

  and resolve or stop doing your tasks to race up to the panel

  20.0  VISUAL SIGHTINGS

LOUSMA  Let's talk  about visual  sightings.  Any comments  on  countdown.

  You saw your  way to  the  booster  or  you didn't  see  that.

  Visual  sighting no problem there.

BEAN  You might  want  to  talk  about  the  visual  sightings  on that

  orbit when  Owen  and Jack  saw the  satellite.

LOUSMA  Yes,  let's  go through countdown.  Any visual  sightings  on

  countdown that  were  significant?  We  saw the  swing  arm go

  away and all that kind of thing.

  Powered Flight:  I watched the  booster protector cover  go

  off and lots  of  flashes  and  debris  and everything  in  every

  separation, but  that's  all norminal.  During orbit:  -

GARRIOTT  Do you want to talk  about  that  satellite?

LOUSMA  I  saw a couple  of  satellites that  appeared like  a  satellite

  would  on the  Earth.  I  saw  one  that was  not  like  one  you

  would  see  on  Earth,  so why don't  you mention  it.

GARRIOTT  Okay,  about  a week  or 10  days  before  recovery and we were

  still waiting  for  information to be  supplied to us  about  the

  indentification.  Jack  first  noticed this  rather  large  red star

  out  the  wardroom window.  Upon close  examination,  it  was much

  brighter than Jupiter  or  any of the  other planets.  It had

  20-1
GARRIOTT  a reddish hue to it, even though it was well above the
(CONT'D)
  horizon.  The light from the Sun was not passing close to

  the Earth's limb at the time.  We observed it for about

  10 minutes prior to sunset.  It was slowly rotating because

  it had a variation in brightness with a 10-second period.

  As I was saying, we observed it for about 10 minutes, until

  we went into darkness, and it also followed us into darkness

  about 5-seconds later.  From the 5- to 10-second delay in

  it's disappearance we surmised that it was not more than 30

  to 50 nautical miles from our location.  From it's original

  position in the wardroom window, it did not move more than

  10 or 20 degrees over the 10 minutes or so that we watched it.

  It's orbit was very close to that of our own.  We never saw

  it on any - earlier or succeeding orbits and we'd be quite

  interested in having its identification established.  It's

  all debriefed in terms of time on channel A, so the percise

  timing and location can be picked up from there.

LOUSMA  Okay, other visual sightings was the one out the wardroom

  window.  That sunrise or sunset which finally led us to the

  RCS leak in the command module.  It disappeared like

  thousands and thousands of stars out there; all of them

  different sizes and drifting along the X-axis.  The one that

  we already mentioned.  The one right after insertion where

  we saw the leak in the same manner of the RCS streaming towards

GIE.SON  are still on the windows.  Just what that material is, I'm not
(CONT'D)
  sure.  But the remaining pieces should be useful for contamina-

  tion  studies.

CARR  One other item is the ammonia odor in the head which we dis-

  covered about the last week in the mission.  We weren't sure what

  was causing it.  Bill had changed out the charcoal canister.

  We disconnected the boot between the charcoal canister and the

  blower above it and took a sniff of that.  We smelled, no ammonia

  there.  When we connected the boot back up to the blower, a

  very strong ammonia odor came from the blower output.  Thus it

  appears that the source of the smell was the blower unit itself

  and not the charcoal canister.  As we said in our report of it

  to the ground, we decided that it was tolerable for the rest of

  the mission.  Therefore, we didn't get into the mode of finding

  another blower to put in there.  I feel that the odor very

  definitely increased in intensity during the final week of the

  mission.

CARR  One other area of unusual events that we reported on the dump

  tapes was that on occasion we saw some lights flashing outside

  with very a definite motion relative to ours.  We presumed that

  they were other pieces of Skylab, or possibly other satellites.

  We reported our two or three sightings of that kind as soon as

  they occurred.  We have no special comments concerning them,

  7-8
CARR  but we did find it very interesting to be able to see other
(CONT'D)
  objects up there with us.  The fact that one or two of them

  appeared to be tumbling was apparently due to the oscillation

  of the light flashes that we were getting from them.

POGUE  The OWS Heat Exchangers:  There's a major design flaw there in

  that filters were not installed upstream of the OWS heat exchanger

  vanes.  When we first arrived, the vanes were so uniformly coated

  with lint that I thought there was some kind of anodized surface

  on them.  I was never fully convinced that I had done the

  vacumming job properly; therefore, I fabricated a special tool

  that fit flush against those surface vanes so that I could

  exert a good vacuum.  Though they are not supposed to be con-

  densive heat exchangers, I sucked quite a bit of condensate water

  out of them.  I tried the best I could to keep those things

  clean, yet I never did get all that lint pulled out of there.

  That is why I think we needed a filter in the system.

GIBSON  EVA anomalies might also be mentioned here.  For example, you

  had the water leak outside, and I also got a water leak.

POGUE  One thing that was not mentioned on air-to-ground as a possible

  cause of the problem was the single-point failure that exists

  in the mechanical way that the PCU composite connector is

  hooked to the PCU.  I was able during EVA, maneuvering through

  the clothesline ropes, not only to open the lock but also to

  extend the arm which pulls the PCU composite connector off.
