GOES-M Update
Our ninth, and final, Apogee Maneuver Firing (AMF #9) was successfully
executed today, Thursday, August 9, at 1:47pm EDT. The burn lasted
6 minutes and 15 seconds- 375 seconds in total. The Main Spacecraft
Thruster (MST) flange temperature reached 201 degrees C, well below
the abort criteria limit. The flange temperature profile tracked that
of the previous burns. Following this maneuver the spacecraft was
configured back to a normal sun acquisition mode. All subsystems are
safe and remain well within limits. Off Axis Sun Acquisition will
be commanded during back orbits in order to reduce telemetry and command
nulls. This maneuver raised perigee approximately 6168 km and increased
the orbital period to approximately 27 hours. The orbit after AMF#9
will actually be slightly super-synchronous, and won't be GEO until
after the AAMs. The last MST firings will occur at perigee during
the upcoming AAMs which will be performed this weekend.
The next maneuver, AAM, part 1 is scheduled for Saturday, August 11,
at 9:29am EDT, with a burn duration of 4.67 minutes.„
