Mission details:

• The AMC-9 satellite has failed in geostationary orbit. AMC 9, a Thales Alenia Spacebus 3000B3 model with a launch mass of 4100 kg, belongs to SES World Skies (formerly to SES Americom; AMC 9 is short for Americom-9). At about 0727 UTC on Jun 17, 2017 an event occurred to the satellite which made a significant change to its orbit. The prograde component of the velocity change was about 0.45m/s, causing its orbital period to increase and the satellite to drift off its 83.0W station at about 0.17 degree/day west. A larger in-plane nadir velocity change of about 13m/s increased the satellite′s orbital eccentricity.
• On Jul 1, 2017 with AMC 9 drifting over 84.6W, SES reestablished contact with the satellite. On Jul 2, it was revealed that several debris objects had been observed in the vicinity of the satellite, suggesting partial disintegration of the spacecraft.
