Tim Peake has become the first person to manoeuvre a rover robot through a darkened, simulated Martian landscape while orbiting the Earth from space.
The British astronaut remotely controlled the explorer from aboard the International Space Station.
He piloted the rover through the Mars-like rocky hangar at Airbus Defence and Space in Stevenage.
But Major Peake did not have it all his own way. The vehicle briefly became stuck on a large fake rock and lost signal for around ten minutes during the pioneering experiment.
Under his guidance, the British-built Rover travelled around 20 metres (65ft) during the two-hour test, and entered a mocked-up darkened cave.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
