[Isocops] IBEX Orbit# 90 ATS (19-27 Aug 10)

All,
	looked over the ATS; I approve.

	There are two lines in the Forecast .oef that are not in the 
short-term .oef:

2010-08-28T21:37:46.305Z,MoonInLoFovStart,orbit:91
2010-08-29T18:17:05.062Z,MoonInLoFovStop,orbit:91

	Sigh. (Somebody should probably take diff off my computer :-) 
.) That outage isn't in the current orbit anyway, so it's not an 
issue for this ATS, but it still bugs me. Those don't appear to cross 
the border of the short-term .oef; is there some reason they don't 
appear in it, but do in the forecast .oef?


	I missed the contact times text file that's usually attached, 
but from a PL point of view that's irrelevant. I'm hoping the times 
are:

2010/08:23:14:00:00 to 2010/08:23:14:35:00 (apogee contact)
2010/08:27:00:15:00 to 2010/08:27:00:50:00 (dump and burn :-) )
2010/08:27:11:15:00 to 2010/08:27:11:50:00 (dump)

	Ascending and Descending macros execute at the proper times 
WRT 15-Re crossings.

	The inertial pointing maneuver points us in a safe direction 
at the time of the burn, and at the ascent and descent for the next 
orbit:
