Both briefings will be streamed from NASA's Johnson Space Center in Houston, USA. The first, at 19:00 CEST Wednesday 6 October, will see participants from ESA, NASA and SpaceX present an overview of the Crew-3 mission and discuss the upcoming crew rotation.

This overview will be followed by a news conference at 20:00 CEST Thursday 7 October, featuring all four Crew-3 crew members: ESA astronaut Matthias Maurer, and NASA astronauts Thomas Marshburn, Raja Chari and Kayla Barron.

Crew-3 is scheduled to be launched on a SpaceX Crew Dragon spacecraft from Launch Complex 39A at NASA’s Kennedy Space Center in Florida, USA, at 08:43 CEST Saturday 30 October. Sunday 31 October will remain a backup date, should a second launch attempt be required.

Matthias and Kayla will be mission specialists aboard the Dragon capsule, working closely with commander Raja and pilot Thomas to monitor the spacecraft during the dynamic launch and re-entry phases of flight.

A launch on 30 October will see Crew-3 arrive at the International Space Station early 31 October, after an approximately 22-hour journey, for a short overlap with the astronauts that flew to the Station as part of the Crew-2 mission. Crew-2 includes ESA astronaut Thomas Pesquet who recently became the first French and fourth ESA astronaut in command of the International Space Station.
