British astronaut Tim Peake and NASA's Tim Kopra ventured outside the International Space Station early Friday to repair a power unit during a spacewalk -- and documented it with an out-of-this-world selfie:
The astronauts were tasked with replacing the power system’s Sequential Shunt Unit, which is an electrical box. After about 2 hours and 11 minutes, the astronauts installed a replacement unit and brought full power back to the space station. (See the video above.)
As Peake floated out, space station commander Scott Kelly called out, "Hey Tim, it's really cool seeing that Union Jack go outside. It's explored all over the world. Now it's explored space."
Replied Peake, the first spacewalker to wear the Union Jack on the shoulder of his suit: "It's great to be wearing it, a huge privilege, a proud moment."
The astronauts are safe and the helmet water has been analyzed to determine where it came from in the suit.
