Nasa astronaut Suni Williams, one of two astronauts stuck on the International Space Station, has completed her first spacewalk since arriving.

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.

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.
