Walker to Command Station Until Departure at End of April
Walker to Command Station Until Departure at End of April
NASA astronaut Shannon Walker of Houston will assume command of the International Space Station today from Roscosmos cosmonaut Sergey Ryzhikov. Walker will lead the Expedition 65 crew for almost two weeks until she returns to Earth with her crewmates aboard the SpaceX Crew Dragon spacecraft.
NASA TV is broadcasting the traditional change of command ceremony beginning at 3:45 p.m. EDT today.
Ryzhikov will depart the orbiting lab on Friday with his Expedition 64 crewmates Kate Rubins of NASA and Sergey Kud-Sverchkov of Roscosmos. The trio will undock from the Poisk module inside the Soyuz MS-17 crew ship at 9:34 p.m. and parachute to a landing in Kazakhstan about three-and-a-half hours later.
The seven-member Expedition 65 crew will be waiting for the arrival of four new Commercial Crew members due to launch to the station on April 22 at 6:11 a.m. SpaceX Crew-2 Commander Shane Kimbrough and Pilot Megan McArthur will be guiding the SpaceX Crew Dragon vehicle toward the station with Mission Specialists Akihiko Hoshide and Thomas Pesquet. The new quartet will dock to the Harmony module’s forward-facing international docking adapter a little less than 24 hours later.
11 people will occupy the orbiting lab until April 28 when the four members of SpaceX Crew-1 end their 162-day space research mission. Michael Hopkins will be in charge of the Crew Dragon as Victor Glover pilots the vehicle, with Walker and Soichi Noguchi inside, when it undocks from Harmony’s space-facing port at 7:04 a.m. They will parachute to a splashdown off the coast of Florida about five-and-a-half hours later.
The day before the Crew-1 departure Walker will hand over station command to Hoshide who will lead the Expedition 65 crew. Hoshide will be the second astronaut overall from the Japan Aerospace Exploration Agency to lead a station crew since Koichi Wakata commanded Expedition 39 in 2014.

Walker Takes Command Thursday Ahead of Two Departures and Next SpaceX Crew
Walker Takes Command Thursday Ahead of Two Departures and Next SpaceX Crew
Ten people occupy the International Space Station today but that will change on Friday when three Expedition 64 crew members return to Earth. Soon after that, four new Commercial Crew members will launch to the orbital lab when it will temporarily host 11 crew members.
Houston native and NASA astronaut Shannon Walker is preparing to take command of the space station on Thursday when Commander Sergey Ryzhikov hands over control before departing the next day. NASA TV will broadcast the traditional change of command ceremony from Expedition 64 to Expedition 65 live beginning at 3:45 p.m. EDT.
Expedition 65 officially begins when Ryzhikov undocks inside the Soyuz MS-17 crew ship with Flight Engineers Kate Rubins of NASA and Sergey Kud-Sverchkov of Roscosmos. The automated undocking command will come at 9:34 p.m. on Friday when the Soyuz spacecraft will slowly back away from the Poisk module. Less than three-and-a-half hours later the three space travelers will parachute to Earth inside their spacecraft after a 185-day space research mission.
The second operational crew mission from SpaceX is gearing up for launch on April 22 from the Kennedy Space Center in Florida. Two NASA astronauts, one Japan Aerospace Exploration Agency (JAXA) astronaut and one ESA (European Space Agency) astronaut will ride inside the Crew Dragon spacecraft to the station to complete the Expedition 65 crew. NASA TV will be on air live broadcasting the 6:11 a.m. launch next Thursday. NASA TV’s continuous coverage will also show the docking taking place the following day at 5:30 a.m.
The four SpaceX Crew-2 astronauts are all veteran astronauts having previously launched to space on space shuttles and Soyuz crew ships. Crew-2 Commander Shane Kimbrough rode to the station twice on space shuttle Endeavour in 2008 and the Soyuz MS-02 crew ship in 2016. Pilot Megan McArthur flew aboard space shuttle Atlantis in 2009 to service the Hubble Space Telescope. JAXA astronaut Akihiko Hoshide took two rides to low-Earth orbit, the first aboard space shuttle Discovery in 2008 and the second in 2011 aboard the Soyuz TMA-03M spacecraft. This will be ESA astronaut Thomas Pesquet’s second space mission, his first aboard the Soyuz MS-03 crew ship in 2016.
Less than a week after the veteran quartet’s arrival, the four SpaceX Crew-1 astronauts will return to Earth after working in space for 162 days. Walker, along with her commercial crewmates Michael Hopkins, Victor Glover and Soichi Noguchi, will undock from the Harmony module’s space-facing international docking adapter on April 28 at 12:04 p.m. and splashdown off the coast of Florida about five-and-a-half hours inside their Crew Dragon vehicle.
