We have already talked about the co2 partial pressure.
It was below zero the entire flight except during tape dumps
when it jumped up due to a glitch that the tape dump puts in
the TM system. Radiator operation and configuration•••We
ran radiator on all the time except for two checks that were
made. Actually when we opened circuited the fuel cells be­
fore we brought them back on the line, we went to RADIATOR
BYPASS twice.
Then we went to ·RADIA'IDR BYPASS once when we
wanted to get the water out of the ECS System.
One time
during the flight we were picking up water.
This might be
a good place to cover that.
We were picking up water coming
out of our suit inlet hose, in quite large quantities.
We
called the ground, and they suggested that perhaps the vater
boiler was not venting. They called up the procedure that
included putting on evaporator heat, turning off the radia­
tor and going to bypass on the radiators and rota.ting the
spacecraft at 10 degrees per second. This threw out large
amount of water and things got back to normal.
Later on in
the flight we noticed the same thing, but we were busy align­
ing the platform and other things and we did not want to
setup roll-rates. All we did was put the suit coolant to
warm and put both suit fans on and blew the water out of
t he system, and that worked also.
We did notice that during
