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.

Suni Williams, the commander of the International Space Station (ISS), recently embarked on her eighth spacewalk, a significant achievement after overcoming previous safety hurdles. Last summer, a spacewalk was abandoned when water leaked into an astronaut's suit.
