NASA astronauts Sunita Williams and Butch Wilmore, stranded on the ISS for months, stepped out for their first spacewalk on Thursday.

NASA astronauts Suni Williams and Butch Wilmore took their first spacewalk together since arriving at the International Space Station last June. They performed maintenance tasks and checked for microbes on the station's exterior.

US President Donald Trump has requested ‘First Buddy’ Elon Musk to bring ‘stranded’ Nasa astronauts Sunita Williams and Butch Wilmore from the International Space Station (ISS). The duo have been in space for the past seven months and aren’t expected to return before March.
