ISS trio end ISS adventure with Soyuz TMA-14M landing

NASA astronaut Barry Wilmore – along with flight engineers Alexander Samokutyaev and Elena Serova – bid farewell to their six month tour on the International Space Station (ISS) arrived home aboard their Soyuz TMA-14M spacecraft on Wednesday. Their mission concluded with a parachute-assisted – loss-of-communication drama – landing on the steppe of Kazakhstan early on Thursday morning local time.

Soyuz Return:

Wilmore, Serova and Samokutyaev arrived at the Station in September of last year and served as flight engineers for ISS Expedition 41 until November – at which time Wilmore assumed command of Expedition 42.

Their return completed 167 days in space on a mission covering almost 71 million miles.

Wilmore logged 178 days in space on two flights, the first of which was on space shuttle mission STS-129 in 2009. Samokutyaev spent 331 days in space on two flights, the first of which was on Expedition 27/28 in 2011.

This was Serova’s first flight into space.

“Butch” Wilmore was also involved in three major spacewalks near the end of his tour of duty with the orbital outpost.

In preparation for that safe trip home, the Soyuz TMA-14M crew donned their Sokol launch and entry suits, closed the hatch between the Orbital Module (BO) and Descent Module (SA), and strapped themselves into their Kazbek couches inside the SA.

Following undocking, the Soyuz enjoyed a few hours of free flight as it departed from the Station’s neighborhood.

“We wish you a good flight and a soft landing,” was the message between the separating crews.

The deorbit burn was the next key milestone of the return leg, conducted around one hour ahead of landing.

The burn took four minutes and 41 seconds to complete, reducing the Soyuz’s velocity just enough for it to begin the plunge back to Earth. This was not immediately confirmed due to a loss of communications, which became more dramatic as the blackout continued – prior to the relief of the re-establishment of audio with the crew.

The next immediate task involved the extraction of the crew from the SA by the Russian recovery forces that raced to the Soyuz’s aid.

The crew were transferred almost immediately on to special chairs, where medical checks were conducted, ahead of being moved to a medical tent by all terrain vehicles to prepare them for transit.

Samokutyaev and Serova will be flown back to Star City, while Butch Wilmore will board a NASA Gulfstream III aircraft and flown back to Ellington Field in Houston, Texas – via two refuelling stops in Glasgow, Scotland, and Goose Bay, Canada.

At the time of undocking, Expedition 43 officially will begin aboard the station under Terry Virts’ command.

Along with his crewmates Anton Shkaplerov of Roscosmos and Samantha Cristoforetti of ESA (European Space Agency), the three-person crew will operate the station for two weeks until the arrival of three new crew members.

NASA astronaut Scott Kelly and Russian cosmonauts Mikhail Kornienko and Gennady Padalka, are scheduled to launch from Baikonur, Kazakhstan at end of the month.

This will be a hugely historic mission, with Kelly and Kornienko scheduled to spend a year aboard the complex collecting valuable biomedical data that will inform future deep space, long-duration missions.

Long duration impacts on the human body and mind are deemed to be one of the biggest non-engineering challenges of sending people to the surface of Mars.
