Aussat-B-MFS (with Badr A) [CAST]

Aussat-B-MFS was a mass model of the Aussat-B (later renamed Optus B) comsat launched on the maiden flight of the CZ-2E rocket.

Aussat-B-MFS was a 2700 kg mass model representing a Aussat-B satellite. It was to be put into a geostationary transfer orbit of 340 km × 25740 km with an inclination of 24 by a Chinese build PKS perigee kick stage. On top of the Aussat-B-MFS, the small Pakistani Badr A satellite was carried to be released in low earth orbit.

The satellite was launched from Xichang on the maiden flight of the CZ-2E rocket. The satellite and the PKM kick stage were put into low earth orbit, but due to a failure of the CZ-2E payload attitude and orientation system on the second stage of the CZ-2E the PKM failed to operate as planned. Likely the combination deorbited itself due to the incorrect orientation, as no objects besides the second stage and the Badr A satellite were tracked in orbit.
