Borman Sleep periods . This is one of the areas where we really
made a wise decision. We decided that we would sleep simul
taneously on the regular Houston schedule. We did slide it
back every day to correspond with the precession of the
orbit . When we were scheduled for house-keeping and sleep,
we would close up the windows. We found that the polaroid
filters were not adequate t so , we cut up an aluminized food
bag and placed it between the window and the polaroid shield.
Then , it was really dark inside, it cut out the heat, and
this left us with a real simulated night. As far as we were
concerned, it was night time. We would get up the next day ,
go to work , and it kept us regular. It kept ue relatively
on a constant type of schedule. I thought it was very ,
very good.
Lovell We are going to have to go to that for any of the long
flights , any of the lunar missions. For any of the long
flights we are going to need to use a regular Houston or
Cape day and not change the routine .
Borman On Apollo , with three men , you probably will have to stand
a watch.
Lovell True. But still, you are going to have to keep from getting
too irregular. I thought sleeping in zero- g was very com
fortable . I slept like a log that first week.
Borman Yes, I had troubles sleeping. The M-1 was the culprit. It
