Eutelsat W3

 1999-018A


The W3 satellite replaces Eutelsat 2F4. W Loc are 7 10 and 16E. W3 will go to 7E. Type is Spacebus 3000B2. Launch mass 3177 kg. Dry mass 1380 kg.

Design similar to W2, with a main shaped reflector pair and a steerable antenna.

W3 moved to 22E in Nov 2004; it was observed there by amateurs on Nov 28 while the NORAD report still placed it at 48E.

Soyuz TMA-12M (Cliff)

 2014-013A


7220 kg launch mass of which 564 kg oxidizer and 316 kg fuel. At undocking, 6790 kg of which 432 kg prop.

Soyuz TMA-12M was launched on what was intended as a quick six-hour rendezvous. The DV3 and DV4 burns were computed to be smaller than normal because of launch vehicle overperformance, and a software glitch aborted them. The mission fell back on the old standard two-day rendezvous plan, which completed successfully on Mar 27.

Skvortsov, Artemev and Swanson returned to Earth on TMA-12 in September.
