Just before a SpaceX capsule docked with the International Space Station (ISS) so two astronauts who found themselves in space unexpectedly for nine months could prepare to return to Earth, an 'alien' was spotted on board on NASA's live feed.

A SpaceX Dragon capsule successfully docked with the ISS, rescuing astronauts Sunita Williams and Butch Wilmore after nine months in space. NASAs Nick Hague welcomed them dressed as an ‘alien. Williams and Wilmore will have to wait a few more days before going home aboard the Dragon.

A SpaceX capsule has arrived at the International Space Station, delivering the replacements for NASA's two stuck astronauts

NASA and SpaceX made another attempt on Friday to send a crew up to the International Space Station (ISS) and begin the return of a pair of astronauts.

Butch Wilmore and Suni Williams need SpaceX to get this relief team to the space station before they can check out.

The Falcon 9 rocket is carrying four astronauts who will replace Wilmore and Williams, both of whom are veteran NASA astronauts and retired U.S. Navy test pilots and were the first to fly Boeing's faulty Starliner capsule to the ISS in June.
