NASA and SpaceX anticipate astronauts Williams, Wilmore, Nick Hague, and Aleksandr Gorbunov will depart the space station Wednesday. Williams previously spoke last month to NASA about what it will feel like physically when that space flight comes to an end.

SpaceX launch scheduled for Wednesday will carry replacement crew for astronauts who have been stuck on the International Space Station since their troubled Starliner mission.

Astronauts Sunita Williams, who grew up in Needham, and Butch Wilmore have been living on the space station since June after the Boeing Starliner capsule they arrived on experienced issues while docking.
