Orbit correction: On 17.11.93 during orbit 44300 the engines of Progress-M20 corrected the orbit of the Mir-complex: Ap/per now 395.3/388.2 KM.

Decay of Progress-M20 and safe landing return capsule on 21.11.93:

Undocking of Progress-M20 from Mir at 0236 UTC. Progress-M20 jettisoned the VBK (return capsule) at 0850 UTC. Progress-M20 entered dense layers of the atmosphere at 0851 UTC and decayed. The VBK safely landed not far from Orsk at 0903 UTC. Orsk is a town just north of the border with Kazakhstan. The VBK itself landed just inside Kazakhstans territory. So possibly Russia will have to pay Kazakhstan import duties for the VBK and the cargo.

VBK's cargo:

The cargo mainly consisted of 2 American containers with experiments: The first one is the experiment TREK, which had been installed outside Mir from 4.04.91. This experiment registered particles of super-heavy elements in the cosmic radiation. The 2d American experiment was the grow of biological crystals delivered by the firm Boeing. The VBK brought back to earth some Russian experiments: 2 videocassettes with images made during the survey experiment Panorama, an experiment with Ultraviolet in the earth's atmosphere, a sample of thermo-insulation material exposed to open space and a lot of negative-films.

Progress-M21: It is still unknown when this freighter will be launched for a flight to Mir. This freighter is badly needed, especially for a supply of fresh oxygen. The last days the crew is complaining about problems with the air pressure and oxygen, which cause respiration problems (dry nostrils and throat).
