Okay, I 'll probably go into this a little bit, and
then we can go over the data on it. This was a
fairly simple test. All we did was start at a zero­
zero reference and establish rates of 3 degrees/
second simultaneously in all axes.
We had a sec­
ondary objective, to see when we established these
rates and put them in three axes simultaneously if
we got a scanner ignor light.
And I 'll clear that
one up realy quick.
We put them in at t wo different
times and neither time di d we get a scanner ignore
light .
We di d this at night the first time , didn't
we? That was really the only time we did it.
Just the night one. That's right .
That's right.
We did i t once at night .
I estab­
lished the rates in t hree axes and allowed them to
bui ld up for about 30 seconds .
Then , I told Jim
to go ahead and take control of the spacecraft, and
using visual references to move to a retrofire at­
titude.
I did this in Pulse Mode, I believe, because we were
trying to save fuel.
I think I did it in Direct,
but I did not do it in Rate Command.
I did it in
Direct .
The first thi ng I did was t ry to find t he
horizon so I would have some reference point to
