[Isocops] IBEX Orbit# 148 ATS v001 - approve.

[Mark Tapley]

All,
	partial sign-offs (everything to date is completed) for the 
Apogee and Perigee sun-point maneuvers. The checklists are a little 
out-of-date, as they refer to the requirement for an early Descend 
macro from when we had only one maneuver per orbit and that was a 
sun-point. With our current two sun-points per orbit, the sun angle 
never exceeds 5 degrees (less, in fact, than our normal inertial 
pointing maneuver) baseline, so it's no longer necessary to do an 
early descend.

	I note that according to the oef, we should have Star Tracker 
coverage between

during the second half of the orbit. It might be nice to have a 
contact scheduled for that time, to verify via star tracker that the 
apogee sun-point maneuver worked.

	Of course, we should still be able to verify this by CSS 
anyway with the apogee contact we already have so adding a contact 
would be kind of excessive caution, but I thought I'd mention it.

	Boy do we have a lot of stuff going on this orbit! Battery 
balancing, -Lo gain test, not one but two sun-points. In the future, 
it might be better to space things out a little.
