Expedition 59: The Space Station Mission in Photos

The Expedition 59 mission to the International Space Station begins on March 14, 2019 when the Soyuz MS-12 crew capsule arrives at the station with Russian cosmonaut Aleksey Ovchinin and NASA astronauts Nick Hague and Christina Koch. The other half of the six-person crew arrived with the Soyuz MS-11 in December 2018 during Expedition 58.

The Expedition 59 astronauts had a pizza party in space on April 5, 2019.

"A long week of hard work and spacewalk prep calls for a pizza party," NASA astronaut Nick Hague wrote on Twitter. "Making pizza in space is similar to making pizza on Earth, the only difference is our ovens look a little different and our pizza can float!"

On March 14, 2019, these three Expedition 59 crewmembers will launch to the International Space Station in the Soyuz MS-12 spacecraft. Rookie NASA astronaut Christina Koch (left) will join veteran cosmonaut Alexey Ovchinin (center) and NASA astronaut Nick Hague for a 6.5-month space mission.

Ovchinin and Hague were on board the Soyuz MS-10 spacecraft together during a launch failure on Oct. 11, 2018. Their mission was aborted just a few minutes after liftoff. That launch was Hague's first spaceflight experience. Before Expedition 59, Ovchinin had already logged 172 days in space as a member of Expedition 47/48 in 2016.
