[Isocops] IBEX Orbit# 141 ATS v001 - approve.

[Mark Tapley]

All,
	I have looked at the Orbit 141 ATS v001

IBEX_2011_271_o0141a_v001.txt

and I Approve.

	No constraint violations.

	The PL commands in the ATS v001 match the STF v001 file

IBEX_2011_271_o0141a_v001.stf

per Ken's script.

	PL ascending and descending operations make sense with 
respect to 15 Re ascending, Apogee, and 15 Re descending times from

IBEX_2011_271_o0141a_v001.oef

	Moon in -Lo FOV PMT setback commands are concentric with .oef 
Moon-in-Lo-FOV times and inside by an hour or two, as usual.

	Ground station contact times per

IBEX_Orbit141Contacts_v001.txt

match S/C commands for all 3 contacts. However, the first contact at 
$TIME=2011/09:29:06:58:02 has command for 40K but the ground station 
contact listing says 2K.

	No battery cell balancing.

	Inertial maneuver at the end of orbit 140 left us pointing in 
a safe direction for ascending and descending macros during first 
half of orbit:

	Inertial maneuver at apogee leaves us pointing in a safe 
direction at maneuver and at following Ascending and Descending 
Macros.

	No O-mode this orbit.

	No overlaps to orbit 139, either manual check or per

	Command Approval Checklist attached.

	Comet-viewing O-mode next orbit?
