Butch Wilmore, a fellow astronaut, stuck in space with Williams, revealed how gravity will be the biggest challenge when the two astronauts return home.

Originally scheduled for a short mission, astronauts Sunita Williams and Butch Wilmore have been stranded in space for over eight months. They launched aboard Boeing’s new Starliner capsule last June for what was meant to be a one-week test flight. However, their return was delayed due to technical issues with the spacecraft.

Sunita Williams and Butch Wilmore confirmed that the Crew-10 mission is scheduled to launch from Earth on March 12.
