Soyuz MS-05 was a Soyuz spaceflight which launched on 28 July 2017. It transported three members of the Expedition 52 crew to the International Space Station. MS-05 was the 134th flight of a Soyuz spacecraft. The crew consisted of a Russian commander, and a European and an American flight engineer. It returned to Earth on 14 December 2017 after 139 days on orbit.

Propelled by the simultaneous thrust of the four engines of the first stage and the single engine of the second stage, the rocket headed east to align its ascent trajectory with an orbital plane inclined 51.67 degrees toward the Equator. Slightly less than two minutes into the flight, the ship's emergency escape system was jettisoned, immediately followed by the separation of the four boosters of the first stage. Almost exactly 40 seconds after the separation of the first stage, the payload fairing protecting the spacecraft in the dense atmosphere split into two halves and fell away.

The second (core) stage of the booster continued firing for less than five minutes into the flight. Moments before the second stage completed its firing 4.7 minutes into the flight, the four-chamber engine of the third stage ignited, firing through a lattice structure connecting the two boosters. Moments after the separation of the core booster, the tail section of the third stage split into three segments and fell away.

The third stage continued firing until the command to cut off its engines 8.7 minutes into the flight at 18:50 Moscow Time (11:50 EDT).

The spacewalk program called for the release of several nano-satellites, the installation of science equipment, taking samples for microbial presence on the exterior of the station, photographic documentation of the station's exterior and its components. The planned duration of the spacewalk was six hours five minutes. It was the 9th spacewalk for Yurchikhin and fourth for Ryazansky. The actual duration of the spacewalk reached 7.5 hours.

The Russian Soyuz MS-05 spacecraft undocked from the International Space Station (ISS) and completed its journey back to Earth with its three crewmembers on Thursday. The vehicle undocked at 05:14 UTC ahead of landing on the steppes of Kazakhstan around 08:38 UTC. The Soyuz returned ESA’s Paolo Nespoli, Randy Bresnik of NASA and Sergei Ryazansky of Roscosmos.

An investigation noted issues with the long-term exposure to electromagnetic emissions on-orbit, and the potential to cause issues with the pyro bolts, came after an extensive investigation that included the removal and return of one pyro bolt from Soyuz TMA-12.

Mitigation against this issue has resulted in no further issues with the module separation milestone in any of the following missions.

Once through the plasma of entry interface, the capsule prepared for the deployment of its drogue chute. This prepared the spacecraft for the deployment of its main parachute. This is one of the hardest parts of the return for the crew, which has been described as being inside a washing machine by some returning astronauts.

The exact timing of touchdown, under a “soft” thruster engine firing, is always dependent on a number of factors – such as the impact of winds on the Soyuz chutes – and can vary by several minutes.

With the Soyuz safely back on Earth, ground and air crews converged on the Soyuz and extracted the crew from the SA.

The crew underwent immediate and preliminary health checks once outside their Soyuz spacecraft. All three are then transferred to a medical tent and then prepared for transit away from the landing site.
