Expedition 63 to the International Space Station began in April 2020, after the Soyuz MS-16 spacecraft arrived at the orbiting lab with NASA astronaut Chris Cassidy (left) and Russian cosmonauts Anatoly Ivanishin (center) and Ivan Vagner.

The three-person Expedition 63 will be joined by NASA astronauts Bob Behnken and Doug Hurley, who will arrive May 28 with the first crewed test flight of SpaceX's Crew Dragon spacecraft. If all goes well with SpaceX's demonstration mission, the first operational Crew Dragon flight could bring three more crewmembers to the space station before the end of Expedition 63, which is scheduled to last until October. See photos of the Expedition 63 mission in this Space.com gallery.
