[This article has been updated to confirm the participants of the press conference]NASA is about to give its first press conference just a couple of hours after Crew-9 returned from the space station in a nine-month mission that was only supposed to last eight days.Williams and Wilmore, both experienced astronauts, were the first humans to ride Boeings new Starliner spacecraft to the International Space Station (ISS). But during the flight, which took place in June last year, issues developed with the spacecrafts thrusters. While it was able to dock, engineers harbored safety concerns that prompted them to bring the Starliner home empty, leaving the pair on the ISS until a return flight could be arranged.Please enable Javascript to view this contentEventually it was decided to send Crew-9 to the ISS with two spare seats in a scheduled mission last September. Crew-9s six-month stay ended in the early hours of Tuesday ET as a SpaceX Crew Dragon undocked from the ISS carrying Williams, Wilmore, fellow NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov.During their 286 days in space, Williams and Wilmore experienced 4,576 orbits and covered 121 million miles.
