NASA Astronauts living on the ISS talk with USA TODAY about the experiments they conduct to help humanity hopefully travel deeper into space.

Suni Williams surpasses the most time by a woman on EVA during a spacewalk with Butch Wilmore outside the International Space Station.

Williams and Wilmore both arrived at the ISS last June, aboard the first crewed test flight of Boeing's Starliner spacecraft. The astronauts were only slated for a 10-day mission, but issues with Starliner during docking led to multiple delays in their return, with NASA ultimately deciding to have Starliner make the journey back to Earth uncrewed.
