Replay of today's landing of the Soyuz TMA-03M spacecraft in Kazakhstan at 10:14 CEST (08:14 UT) returning Expedition 30/31 crewmembers Oleg Kononenko, André Kuipers and Don Pettit to Earth after 193 days in space.
The Soyuz TMA-03M landed in the Kazakhstan steppe at 10:14 CEST (08:14 UT) bring an end to the PromISSe mission. ESA astronaut André Kuipers spent 193 days in space.
The Soyuz TMA-03M undocked from the International Space Station at 06:47 CEST (04:47 UT) this morning, starting the return journey to Earth for ESA astronaut André Kuipers, NASA's Don Pettit and Russian cosmonaut Oleg Kononenko. They are set to land in Kazakhstan at 10:14 CEST (08:14 UT).

Expedition 31 crewmembers André Kuipers, Don Pettit and Oleg Kononenko have said their farewells to the rest of the International Space Station crew and entered their Soyuz spacecraft ahead of their return to Earth. The hatches between the ISS and the Soyuz TMA-03M spacecraft were closed at 03:32 CEST (01:32 UT). They will now perform leak checks of their spacecraft and are scheduled to undock from the ISS at around 06:48 CEST (04:48 UT).

Watch the replay from NASA TV:
The Soyuz TMA-03M landing site is located 217 km to the southeast of the Kazakh city of Dzhezkazgan.

Schedule:
03:15 CEST / 01:15 UT -- Expedition 31 farewells and hatch closure coverage (hatch closure at 03:40/01:40 UT)
06:30 CEST / 04:30 UT -- Expedition 31/Soyuz TMA-03M undocking coverage (undocking at 06:47 CEST / 04:47 UT)
09:00 CEST / 07:00 UT -- Expedition 31/Soyuz TMA-03M deorbit burn and landing coverage (deorbit burn at 09:19 CEST / 07:19 UT, landing at 10:15 CEST / 08:15 UT)
Expedition 31 Commander Oleg Kononenko ceremonially handed command of the International Space Station to Russian cosmonaut Gennady Padalka. The two cosmonauts along with their four station crewmates were inside the Zvezda service module for the crew handover.
The sequence of events below are as expected on 1 July for the return of the Soyuz TMA-03M with ESA astronaut André Kuipers, NASA's Don Pettit and Russian cosmonaut Oleg Kononenko. Departure starts with the undocking command at 06:50 CEST (04:50 UT) and ends with landing in Kazakhstan at 10:15 CEST (08:15 UT).
03:32 CEST (01:32 UT) - Hatch closure
06:44 CEST (04:44 UT) - Undocking command to open hooks and latches
06:47 CEST (04:47 UT) - Hooks opened / physical Separation of Soyuz TMA-03M from the Rassvet/MRM1 module at 0.12 m/s

06:56 CEST (04:56 UT) - Separation burn from ISS (15 second burn of the Soyuz engines, 0.55 m/s; Soyuz distance from the ISS is ~15-20 metres)
09:19 CEST (07:19 UT) - Deorbit Burn (4 min 15 sec in duration, 115.2 m/sec; Soyuz distance from the ISS is ~12 km)

09:48 CEST (07:48 UT) - Separation of modules (~23 mins after deorbit Burn; 140 km altitude; undocking command + ~2 hours, 57 mins.)

09:51 CEST (07:51 UT) - Entry interface (101.8 km altitude)

10:00 CEST (08:00 UT) - Command to open chutes (10.7 km altitude)
Two Pilot Parachutes are first deployed, the second of which extracts the Drogue
Chute. The Drogue Chute is then released, measuring 24 square meters, slowing the Soyuz down from a descent rate of 230 m/s to 80 m/s.
The main parachute is then released, covering an area of 1000 square metres; it slows the Soyuz to a descent rate of 7.2 m/s; its harnesses first allows the Soyuz to descend at an angle of 30 degrees to expel heat, then shifts the Soyuz to a straight vertical descent.

10:15:02 CEST (08:15:02 UT/14:15:02 Kazakhstan time) - Landing (Descent take about 3 hours 24 mins) 217 km SE of Dzhezkazgan; 7 hours 1 minute before sunset at the landing site in Kazakhstan.

Listen to ESA astronaut Paolo Nespoli describe his experience of returning to Earth with the Soyuz spacecraft. "To transfer yourself from space back to the ground you have to go through this gruesome, pretty gruelling event," he explains.

After entering the Soyuz TMA-03M spacecraft and closing the hatches at 03:40 CEST, the Soyuz is set to undock from the Station at 06:53 CEST on Sunday morning. A couple of hours later at 09:19 CEST, a 4 minute 25 second deorbit burn will start the Soyuz on it's journey towards Earth's atmosphere.

The descent module rotates, placing the strongest parts of the heatshield towards the reentry direction, so that it can absorb most of the heat caused by friction. Reentry occurs at an altitude of 101.8 kilometres. The speed is reduced dramatically and the crew is pushed back into their seats by a force of 4–5 g. This is equivalent to four to five times their own body weight.

After landing, the crew will deploy a communication antenna, so that the rescue teams can pinpoint their precise location. The landing site is located 217 km SE of the Kazakh city of Dzhezkazgan. Once rescued André and Don will be taken directly back to Houston from Baikonur, for rehabilitation and post-flight body data collection. Oleg will return to Star City in Moscow.
Unlike the 2 days between launch and docking with the ISS, reentry and landing on the Steppes of Kazakhstan is a relatively quick procedure, taking no longer than three and a half hours from undocking to touchdown.
