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

One of the two astronauts stranded at the International Space Station (ISS) has taken their first space walk since arriving at the station nearly seven months ago.

Pettit is now in the midst of his third stint on the International Space Station, and the decade he had to prepare for his current stay in orbit was put to good use. Accordingly, he is well stocked on cameras, lenses, and plans to make the most of six months in space to observe the planets and heavens from an incredible vantage point.
