Mission overview

This mission brought the 16th long-term crew to the International Space Station on October 10, 2007 and replaced the Soyuz TMA-10 spacecraft as a rescue vehicle. Furthermore, on this mission, Sheikh Muszaphar Shukor, a Malaysian astronaut entered space for the first time.

After six months of work in space, ISS commander Whitson and flight engineer Malenchenko returned to Earth on April 19, 2008, together with the first South Korean space traveler Yi. After an unscheduled ballistic return with a peak load of 8.6 times the acceleration of gravity , Malenchenko reported the safe landing via satellite phone. A short time later the capsule was located and recovered about 420 km west of the targeted landing site at 50 ° 31'N and 61 ° 07'E. During the re-entry, the radio communication was initially severely disturbed and then broke off completely.

Upon re-entry, according to information from NASA, irregularities occurred when the drive module was disconnected. Based on the traces of fire on the capsule, assumptions were made that the capsule flew at least temporarily with the hatch when it re-entered the atmosphere, so that the heat shield was ineffective. Severe fire damage to the antenna can be seen as the cause of the radio communication being broken off upon re-entry.

Problems with the controls had already occurred with the Soyuz TMA-1 and Soyuz TMA-10 and led to ballistic landings. A device error in the TMA-1, a defective cable in the TMA-10 and problems with separating the landing and drive module were identified as the cause of the error. According to Roskosmos , the orbital section of the TMA-11 as well as the TMA-10 was delayed separated from the space capsule, so that the automatic landing system had switched to the mode for a ballistic landing. The reason for this was a problem with the pyrobolt . In order to ensure a trouble-free re-entry for Soyuz TMA-12 , the spaceship was inspected and one of the bolts was dismantled during an unscheduled space exit lasting several hours .
