Undocking command to begin to open hooks and latches that hold the Soyuz tight to the International Space Station (ISS)

19:25:30

Undocking. With hooks opened, physical separation of Soyuz spacecraft from the Poisk module of the ISS at 0.12 metres/second

19:28:30

Separation burn

8-second burn of the Soyuz engines, 0.53 metres/second

Soyuz distance from the ISS is approximately 15-20 metres

21:55:03

Deorbit Burn

4 minutes 41 seconds in duration, 128 metres/second

Soyuz is approximately 32 kilometres from the ISS

(Altitude: 432.7 kilometres)

22:22:29

Separation of Module

(Altitude: 139.9 kilometres)

22:25:20

Entry interface

(Altitude: 99.7 kilometres)

22:26:49

Entry into Plasma and entry guidance begins

(Altitude: 80.4 kilometres)

22:31:36

Exit from Plasma and maximum G-loads (4-5 G's) on the crew

(Altitude: 35.3 kilometres)

22:33:37

Command to open chutes

(Altitude 10.8 kilometres)

  • Two pilot parachutes are first deployed, the second of which extracts the Drogue Chute.
  • The drogue chute is then released, measuring 24 square metres, slowing the Soyuz down from a descent rate of 230 metres/second to 80 metres/second.
  • The main parachute is then released, covering an area of 1000 metres; it slows the Soyuz to a descent rate of 7.2 metres/second; its harnesses first allow the Soyuz to descend at an angle of 30 degrees to expel heat, then shift the Soyuz to a straight vertical descent.
22:47:53

Soft landing engine firing

Six engines fire to slow the Soyuz descent rate to 1.5 metres/second, just 0.8 metres above the ground.

22:47:55

Landing (08:47:55, on , local time in Kazakhstan).
