NASA astronaut Sunni Williams, one-half Boeing Starliner crew who have been stuck on the International Space Station for months, took part in a spacewalk on Thursday to do some repairs to the orbiting laboratory.

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.
