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.
