pretty straightforward. I think Pulse was the
best mode on the spacecraft for the orbit phase .
We were able to save all kinds of fuel, it worked
fine, and it was just about what the doctor ordered .
We didn't use the Horizon Scan Mode during about
the first three days of flight, except for the second
orbit when I think I \\18.S in Horizon Sca.n so that I
could have the freedom to help Ed prepare for his
EVA. The last day we used the Horizon Sca.n Mode,
and I found it to be an excellent mode. There was
only one case when it broke lock and didn ' t recover.
Wasn't that it, F.d.?
You've got it in the book .
We've got in the book and we'll check on that .
The Ho~izon Scan Mode worked essentially for 24
hours without any problem ~and I think it' s an
excellent control mode, It seemed to be very
economical on fuel . We were doing a lot of
yawing around and right at sunrise a.nd sunset it
seemed to get a l ittle nervous , especially if we
had the horizon scanner pointed within about plus
or minus 45 degrees of the sun. The moon didn ' t
seem to affect it at all. I noticed that, occa
sionally, we would ~et some thruster blips with the sun
