GOES-M Update
Our fifth Apogee Maneuver Firing (AMF) #5 was successfully executed today,
Tuesday, July 31, at 11:01am EDT. The burn lasted exactly 11 minutes.
The Main Spacecraft Thruster (MST) flange temperature reached 252.77 degrees,
a little over 5 degrees below the abort criteria limit. The flange
temperature profile during this burn was nearly identical to AMF#4. Following
this maneuver the spacecraft was configured back to a normal sun acquisition mode
and will remain in this mode until the next maneuver. All subsystems are safe
and remain well within limits. The maneuver raised perigee approximately 3657 km
and increased the orbital period to approximately 17 hours.
A total of 4 AMFs remain in order to achieve geosynchronous orbit.
The next maneuver (AMF#6) is planned for Friday, August 3, at 8:01am EDT (DOY 215 @ 1201z).
