Description:

• THE TELKOM 3 satellite was built by ISS Reshetnev with a communications payload provided by Thales Alenia Space. The $200 million satellite′s 42 C-band and Ku-band transponders were to be operated by Telkom, an Indonesian communications firm, for broadcast and data transmission services. The satellite has been placed in a wrong orbit by a Proton-M Russian launcher.

Mission details:

• A Proton launched from Baykonur on Aug 6, 2012 placed a Briz-M upper stage with two communications satellites in a suborbital path. The Briz-M burned to a 173 km initial orbit, and then restarted to reach a 200 x 5000 km intermediate orbit. However the third burn failed after only 7 seconds, leaving the vehicle in a 266 x 5015 km x 49.9 deg orbit instead of continuing towards geostationary altitude. The two payloads and the DTB drop tank separated from the Briz, so there are four objects being tracked in this orbit. They will probably reenter within one year.
• The satellite has been placed in a wrong orbit by a Proton-M Russian launcher. Telkom-3 is an ISS Reshetnev Ekspress-1000H-class satellite for PT Telkom of Indonesia; mass was 1903 kg full.
• The upper stage from the failed Ekspress/Telkom launch, Briz-M No. 99532 (catalog 38746), disintegrated on Oct 16, 2012 presumably when residual fuel and oxidizer came into contact, and generated an as-yet-unknown quantity of orbital debris. The stage was in a 263 x 5012 km x 49.9 deg orbit.
  None of the debris has yet been cataloged.
