Cooper Two other things we have is that you leave preheat
on for 4 minutes prior to flushing. We got one
t remendous big glob of urine ice that broke off
sometime about the fifth day.
Conrad Oh, yes .
Cooper And, man, that indicated that it really bui l t up .
It must have been as big as that box there .
Conrad It looked like one of those sand castles you build .
It was a conica l buildup of ice . The liquid
had flowed out . It kept building up and building
up . But it was still flowing out through the center
like a volcano. The darn thing broke off one day
ou t there , and, boy , I tell you that thing was about
this big around and it was about 3 and 1/2 inches
high. It just went floating right by the spacecraft
and it was pure yellow. Ha , ha! It was about 3 by
4 by 3 or 3 1/2 or 4. About 3 inches in diameter
and about 4 inches high . It was triangular , dribbled
up, rough shaped, but you could see where it was smooth
on the back side where it had actually s tarted to
freeze. Boy , that scared us . We didn ' t want the urine
system to freeze up so we went to 4 minutes . We used
the recommended McDonnell procedures and we revised
those slightly when we found out the tar was beginning
