pointed toward the hori zon scanner although we
never got an unlock light.
We wouldn ' t get an
unlock light, but we 'd ~et a bunch of maybe four
or five thruster blips right there.
Particularly at sunrise.
It would hold.
I thought the Horizon Scan-­
It was definitely getting some spurious signals
through but not enough to break it out all the way.
I thought the Horizon Scan Mode was an excell ent
attitude-hold mode.
Did you notice the water boiler venting, Jim?
Yes, I did.
We kept yawing around to the left .
I believe it was left. I did notice the fact
that we were yawing, but not very much.
We were
yawing a t rates that wer e extremely low and it just
took a pulse every once in a while to handle the
thing.
As a matter of fact, when we were chasing
the booster around a lot at the beginning, I never
even noticed. It was when we were i n the Pulse Con­
trol Mode for a period of time,when we didn ' t do much
thrusting in yaw, that I noticed we did start drifting
off in yaw.
So I did notice the water boiler venting.
