SpaceX Crew-1

SpaceX Crew-1[3][4] (also known as USCV-1 or simply Crew-1)[5] will be the first crewed operational flight of a Crew Dragon spacecraft. The Crew Dragon C207 spacecraft, expected to launch no earlier than 23 October 2020 on a Falcon 9[2] from the Kennedy Space Center, LC-39A, will carry NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker along with JAXA astronaut Soichi Noguchi, all members of the Expedition 64 crew.[6] The mission will be the second overall crewed orbital flight of the Crew Dragon,[7] pending the certification of the vehicle.[8]

Not to be confused with Crew Dragon Demo-1 or Crew Dragon Demo-2.

Crew-1 will be the first operational mission to the International Space Station in the Commercial Crew Program. Originally designated "USCV-1" by NASA in 2012, the launch date has been delayed several times from the original date of November 2016.[9] The mission is expected to last 210 days,[3] and the C207 spacecraft is expected to return to Earth via splashdown[10] for reuse for another future mission.

A Soyuz spacecraft has been designated as backup for the mission.[11]

Background

The first operational mission in the Commercial Crew Program, originally designated "USCV-1" by NASA, was initially announced in November 2012, with a launch date set for November 2016.[9] In late March/early April 2013, it was announced that the launch would be delayed by one year to November 2017.[9] As of mid-August 2020, the date was confirmed as 23 October 2020.[2]

Crew

NASA astronauts Michael S. Hopkins and Victor J. Glover were announced as the crew on 3 August 2018.[12] JAXA astronaut Soichi Noguchi and the third NASA astronaut, Shannon Walker, were added on 31 March 2020 to the crew.[13]

Mission

The Crew Dragon spacecraft serial number C207, will dock to the International Docking Adapter (IDA) on the Harmony module. As of August 2020, the mission is now expected to launch on 23 October 2020, following the return of Expedition 63.[2] There will be four crew members inside the Crew Dragon capsule as a Falcon 9 lifts off from Kennedy Space Center, LC-39A. Over the course of the mission, the astronauts will live and work alongside the three astronauts of the Soyuz MS-17 mission. Together, the two missions will form ISS Expedition 64.

With launch scheduled for 23 October 2020, the astronauts and pre-launch assistants will begin their mandatory quarantine in early October 2020.
