NASA astronauts Sunita "Suni" Williams and Barry "Butch" Wilmore surely didn't think they'd still be on the International Space Station this long when they left Earth in June. In fact, they initially expected to stay for just eight days.

Two NASA astronauts who have been on the International Space Station since June 2024 are preparing for a spacewalk. A spacewalk, also known as an extravehicular activity (EVA), is when an astronaut leaves their spacecraft and works outside in space.

At the time of writing, Williams and ISS crewmate, Nick Hague, are conducting NASA’s first spacewalk in over a year. The pair are scheduled to spend roughly 6.5 hours in the vacuum of space, where they will work on a number of long overdue external repairs and equipment assessments.
