Soyuz TMA-10 was a human spaceflight mission using a Soyuz-TMA spacecraft to transport personnel to and from the International Space Station (ISS). The mission began at 17:31:09 UTC on April 7, 2007 when the spacecraft was launched from the Baikonur Cosmodrome by a Soyuz FG launch vehicle. Soyuz TMA-10 brought to the station two members of ISS Expedition 15 crew, along with one spaceflight participant. It remained at the space station as an escape craft until it was replaced by Soyuz TMA-11 in October 2007.

Soyuz TMA-10 docked to the ISS on April 9, 2007 at 22:10 UTC, following two days of free flight. Its two Russian crew members remained on the station until the spacecraft's return to Earth in October 2007. Spaceflight participant Charles Simonyi returned to Earth aboard Soyuz TMA-9 on April 21, following eleven days of ISS handover operations.
TMA-10 undocked from the ISS at 07:14 UTC on October 21, and deorbit occurred at 09:47. During atmospheric re-entry, the spacecraft transitioned to a ballistic reentry, resulting in it landing west of Arkalyk, approximately 340 km (210 mi) northwest of the intended Kazakhstan landing site.[2] The trajectory was reported by the crew as soon as they came out of the communications blackout caused by plasma surrounding the spacecraft. A ballistic trajectory is a backup re-entry mode that takes over if something fails during normal re-entry. A Commission of Inquiry determined that the ballistic re-entry was caused by damage to a cable in the spacecraft’s control panel, which connected the control panel with the Soyuz descent equipment.[3] Landing occurred at 10:36 GMT.[4] A ballistic trajectory entry had happened previously, with the Soyuz TMA-1 mission that returned Expedition 6.[2] The information about failure of connector in service panel were fault, in fact the Service module (PAO) failed to separate from Reentry module (SA) and the ship entered the atmosphere in opposite orientation. Explosive bolts in connection struts between Reentry module and Service module failed to explode. Fortunately the heat melted failed struts and the reentry module was separated from service module - changed trajectory of the ship caused switch to ballistic emergency landing. The same situation happened during Soyuz 5 mission in 60´s, Soyuz SA then was and still is protected from all directions with thermal insulation, so the struts melted sooner than crew entry hatch was damaged or destroyed which saved the crew. The Russians keeps the failure of Soyuz TMA-10 in secret until it happened again with Soyuz TMA-11 with NASA astronaut onboard. This infuriated NASA (Commission of Inquiry lied to them)[citation needed] and led to further investigation and also to special EVA activity on ISS to check docked Soyuz TMA-12 and its explosive bolts in connection struts.
