Hi All,
I approve orbit 291 ATS commands.
NOTE: the transition to housekeeping occurs 651.5 minutes before thrust
enable presumably due to the insertion of the contact prior to maneuver.
There are two moon in FOV sessions, the second one presumably ends during
apogee.
The orbit pointing follows.
Regards,
Marty
