After being stranded on the International Space Station since June, two astronaut castaways may still be months away from returning to Earth—in part because of incompatible space suits.
The two astronauts, Butch Wilmore and Suni Williams, have had to extend what was supposed to be an eight-day trip on the ISS, because of a helium leak and thruster malfunctions on their Boeing-made Starliner spacecraft. NASA and Boeing are testing to see if it’s safe for the astronauts to return on the Boeing Starliner, but are also considering alternatives given the possible risks.
