A trio of space travelers, including NASA astronaut Mark Vande Hei, is scheduled to launch aboard the Soyuz MS-18 spacecraft from the Baikonur Cosmodrome in Kazakhstan to the International Space Station at 3:42 a.m. EDT (12:42 p.m. Kazakhstan time) Friday, April 9.

Beginning at 2:45 a.m., NASA Television, the agency’s website, and the NASA app will provide live coverage of the crew’s launch. Teams at the Baikonur Cosmodrome in Kazakhstan are making final preparations for the liftoff of Vande Hei and Russian cosmonauts Oleg Novitskiy and Pyotr Dubrov.

The launch will send the crew members on a two-orbit, three-hour journey to the space station, where they will join the Expedition 64 crew, temporarily increasing the orbiting laboratory’s population to 10 people.

They will join NASA Flight Engineer Kate Rubins, who arrived on the station with Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov of Roscosmos in October 2020, and the crew of the SpaceX Crew Dragon Resilience – NASA astronauts Michael Hopkins, Victor Glover, and Shannon Walker, as well as Japan Aerospace Exploration Agency (JAXA) astronaut Soichi Noguchi – who have been in orbit since November.

It will be the second spaceflight for Vande Hei, the third for Novitskiy, and the first for Dubrov. The launch comes three days before the 60th anniversary of cosmonaut Yuri Gagarin’s launch to become the first human in space and the 40th anniversary of the first launch of NASA’s space shuttle.

During their six-month mission, the Expedition 65 crew will continue work on hundreds of experiments in biology, biotechnology, physical science, and Earth science aboard the International Space Station, humanity’s only permanently occupied microgravity laboratory. Work on the unique microgravity laboratory advances scientific knowledge and demonstrates new technologies, making research breakthroughs that will enable long-duration human and robotic exploration of the Moon and Mars.
