After nine months in space, NASA astronauts Butch Wilmore and Suni Williams finally returned to Earth on Tuesday, March 18 — but now inquiring minds want to know, how much will they get paid for their extended stay at the International Space Station?

Because of faults with Boeing’s Starliner, Suni Williams and Butch Wilmore had to wait months for a ride back to Earth on a different spacecraft.

As the commander of NASA's SpaceX Crew-9 mission, Col. Nick Hague traveled 72,553,920 miles, spent 171 days in space, and completed 2,736 orbits, according to information from his service branch.
