Working in space comes with its own unique set of challenges. Astronauts can expect to work for hours on end in cramped conditions and often without much sleep.

However, the view from space makes makes it worthwhile, as this video attests.

Nasa astronaut Randy Bresnik tweeted a video of his short downtime during a spacewalk on the International Space Station.

He wrote: "Sometimes on a #spacewalk, you just have to take a moment to enjoy the beauty of our planet Earth."

Bresnik shot the video using Go-Pro footage with fellow astronaut Joe Acaba as they refurbished the station's robotic arms extensions.

Since it was published late last night (November 27) the short 90-second video has been retweeted 6,500 times and liked over 10,000 times.

Bresnik, 50, has been in space since July as the flight commander of Expedition 52/53 and is working to refurbish parts of the ISS satellite. Randy is a retired former pilot with the US Navy.

This is not the first time Bresnik has been sent to space. In November 2009, he flew as a Mission Specialist on STS-129 and completed nearly 12 hours of spacewalks during his time.

Like his ISS predecessors, Bresnik has released spectacular images from space to his army of Twitter followers.
