[Isocops] IBEX Sun Precession Maneuver 25 Feb 11

Hey Sheral,
 
Set thrust time is 900 (15min). We would like a 25 min burn so I think this needs to be 1500.
 
Also - I'd like to send up the STX OFF command as a single command right at the beginning of the pass. We will take the beginning of the pass to assess the health of the SCB & P/L before we upload the ATS.
 
Thanks,
Chelle
