Conrad Let me just add one thing. My recommendation is
tha t you are going to have to be extremely careful
with the mission planning people becau:rn I saw what
happened to us . Every f l ight is going to have a
different rendezvous. Somebody is going to want
to start changing s omething, or mickey•-mousing
around. I think it is going to wind u:;, to be a crew
responsibility and that a couple of mo,~ths before the
f light they really put the axe to them to stop.
vlhether it is the best way to do it or not , the more
you do in rendezvous, the more complicated it is
and the more time critical it is doing the maneuvers .
The computer is a complex little gadget and can really
f oul you up if you make one mistake. '3o , training
wise I can1 t emphasize running the mis3ion the way
it is really going to run in real time. We haven't
enough time to really get it down.
Cooper Cut i t off at an early date , s o you ca1 adequately
t rain on i t . I can't conceive that you could ever
get the off-sets that we were using in some of our
r etrofire training. Plus , I don ' t th~1k we are using
the right torquing moments on our Rate Command
system. The trainer doesn 1 t have anyw.~ere near the
brute power that the actual RCS Rate CJmmand has .
