Progress M-07M

Launch and docking

Progress M-07M was launched by a Soyuz-U carrier rocket, flying from Site 31/6 at the Baikonur Cosmodrome. The launch occurred at 10:22:28 UTC on 10 September 2010. The launch had previously been scheduled to occur at 11:11 UTC on 8 September 2010, however it was delayed due to unfavorable weather conditions. After the launch the spacecraft reached a preliminary orbit of 195 by. A series of engine firings over the next two days guided Progress M-07M to the rendezvous.

Docking with the aft port of the Zvezda module of the ISS had been scheduled for around 12:37 UTC on 10 September 2010, however due to the launch delay, it occurred on 12 September at 11:58 UTC. The approval to begin the 11-minute final approach was issued by the Russian flight controllers after assessing the systems during a brief stationkeeping hold with about 167.6 m between the space station and the Progress spacecraft. The docking was executed flawlessly by the Kurs automated rendezvous system.

Cargo

Progress M-07M carried 2515 kg of cargo to the International Space Station. This consisted of 1120 kg of fuel, 49 kg of oxygen, and 210 kg of water. The remaining 1136 kg was dry cargo, including components for the station's life support system, equipment for conducting maintenance and repairs, supplies for sanitation and hygiene, food, medical equipment, clothes and parcels for the cosmonauts aboard the station, cameras, and supplies for outfitting the Zarya, Poisk and Rassvet modules.

Orbit raising manoeuvres

Progress M-07M was used for three manoeuvres to raise the orbit of the International Space Station. The first, which used eight of the Progress spacecraft's attitude control thrusters, was carried out on 15 September 2010. The engines ignited 09:04 UTC, and burned for 526 seconds, raising the orbit of the space station by 2 km to 356 km, in preparation for the undocking and landing of Soyuz TMA-18 on 25 September 2010, and for the docking of Soyuz TMA-01M on 10 October 2010.

A second orbit raising manoeuvre was conducted at 19:41 UTC on 20 October 2010, in preparation for the docking of Progress M-08M. The manoeuvre lasted 228.7 seconds, and left the space station in an orbit with a perigee of 350.7 km and an apogee of 375.7 km. Progress M-08M was launched on 27 October 2010, and successfully docked two days later.

The third manoeuvre was conducted on 22 December 2010, when eight thrusters were again used to raise the space station's orbit. This manoeuvre raised the orbit of the space station by 4.2 km to 352.9 km in preparation for the arrival of the Progress M-09M spacecraft, which is scheduled to launch on 28 January 2011, and for the docking of OV-103 on the STS-133 mission.

Undocking

It remained docked to the space station until 20 February 2011 when it undocked to make way for the Johannes Kepler Automated Transfer Vehicle. After undocking, it was deorbited to a destructive reentry over the spacecraft cemetery in the Pacific Ocean. Filled with trash and spent equipment on board the ISS, Progress M-07M drowned in the Pacific Ocean at 19:58 Moscow time.
