GOES-M Update
Apogee Maneuver Firing (AMF) #1 was terminated early today by ground
command when the Main Spacecraft Thruster (MST) flange temperature
exceeded its 260 degree abort criteria limit. The burn was terminated
approximately 13 minutes into a scheduled 53 minute burn. The flange
temperature is used to give an indication of the thruster valve
temperature trends that will be experienced as a result of soakback
following maneuver completion. The spacecraft was configured back to a normal sun
acquisition mode following the abort command with no problems. All
subsystems are safe and remain well within limits.
Shortly after achieving Sun Acquisition, engineers and flight dynamics
personnel convened a meeting to start discussing AMF re-plans that will
be implemented over the next several days. Preliminary analysis and
results from the meeting indicate that the only impact to the mission
timeline will be to conduct shorter more frequent AMFs over the next several
days to raise the orbit to a geostationary altitude. Mission planners
are in the process of scheduling ground station and network resources to
accommodate the additional maneuvers. Additional meetings will be
conducted on a Thursday to finalize AMF plans.
