Vande Hei and Dubrov launched April 9, 2021, on Soyuz MS-18, and will wrap up a 355-day mission spanning 5,680 orbits of Earth and more than 150 million miles. During the long-duration mission, Vande Hei broke the record for longest single spaceflight by an American astronaut, previously held at 340 days. Vande Hei will wrap up his second spaceflight with a total of 523 days in space. Shkaplerov launched on Soyuz MS-19 on October 5, 2021. This was Dubrov’s first flight. Shkaplerov is ending his fourth mission with 708 cumulative days spent in space.
In advance of Soyuz departure coverage, Shkaplerov will hand over command of the station to NASA astronaut Tom Marshburn during a change of command ceremony. The event will air live on NASA TV, the NASA app, and the agency’s website beginning at 9:45 a.m. Tuesday, March 29.
At the time of undocking, Expedition 67 will formally begin aboard the station, with new station Commander Marshburn, NASA astronauts Raja Chari and Kayla Barron, ESA (European Space Agency) astronaut Matthias Maurer, and Roscosmos cosmonauts Oleg Artemyev, Denis Matveev, and Sergey Korsakov.
After landing, the Soyuz MS-19 crew will split up, as per standard crew return practice, with Vande Hei returning to his home in Houston, while the cosmonauts fly back to their training base in Star City, Russia.
