Progress M-20M

 2013-039A


The M-20M flight, ISS mission 52P, made a quick flight to ISS, carrying a cargo with the last minute addition of EMU spacesuit repair tools. The spacecraft was 11F615A60 No. 420. Launch mass was 7283 kg, including 2366 kg; 880 kg prop, 1491 kg dry cargo and 877 kg wet cargo (prop, oxygen, water and air). EVA accounted material (DPN/VRM) 107 kg. Undocking mass 6037 kg.

The Izgib experiment had two goals  - to test Progress in a gravity gradient stabilized mode, and a solar orientation rotating mode to determine the spacecraft's mass and inertia tensor.
