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

NASA astronaut Suni Williams, one of two astronauts stranded on the International Space Station (ISS) for seven months, conducted her first spacewalk Thursday during the extended mission.

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.

Suni Williams, the station's commander, had to tackle some overdue outdoor repair work alongside NASA's Nick Hague. Plans called for Williams to float back out next week with Butch Wilmore.

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.
