Nick Hague and Suni Williams spent six hours working on NICER, AMS and other equipment outside the International Space Station on Thursday (Jan. 16).

The two astronauts have a busy day ahead of them. Hague and Williams will "patch light leaks in the NICER X-ray telescope, then ready the Alpha Magnetic Spectrometer for future upgrades," NASA officials wrote in a Jan. 15 blog post.

NASA astronauts Butch Wilmore and Suni Williams were only meant to be away from Earth for eight days - but have been stuck on the International Space Station for the last seven months

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.

One of NASA's two stuck astronauts is getting a change of scenery. Suni Williams stepped out on a spacewalk Thursday, her first since arriving at the International Space Station seven months ago.
