Expedition 63 Mission Patch

Expedition 63 began April 17, 2020 when the Soyuz MS-15 undocked from the ISS, carrying the Expedition 62 crew home. Remaining onboard are Expedition 63 commander Chris Cassidy (NASA) and flight engineers Anatoly Ivanishin (RSA) and Ivan Vagner (RSA).

While operating and maintaining the space station's systems, the Expedition 63 crew will continue the many science experiments in progress as well as initiate new investigations and undertake technology demonstrations.

It is possible the crew will remain a three person crew for the duration Expedition 63. However, plans call for them to be joined by Bob Behnken (NASA) and Doug Hurley (NASA). Behnken and Hurley are expected to arrive with the docking of DEMO-2 (SpaceX). DEMO-2, the last test flight of the Crewed Dragon before the Commercial Crew Program resumes fully operational launches from American soil, is expected to launch to the ISS on May 27, 2020. Information about when DEMO-2 will return its crew to Earth is unavailable at this time.

Expedition 63 is expected to conclude October 22, 2020.
