One hundred potential astronauts have been shortlisted for a mission to Mars.
Five of the those chosen to head to the Red Planet are British.
But there’s a catch, it’s a one-way trip.
More than 200,000 people applied to join the proposed trip aiming to set up a permanent human colony in 2024.
The Brits lined up for the mission:
Ryan MacDonald, a 21-year-old masters student from Derby
Maggie Lieu, 24, a PhD student in astrophysics at the University of Birmingham
Hannah Earnshaw, 23, a PhD student in astronomy at Durham University
Alison Rigby, 35, a science laboratory technician, from Beckenham in Kent
Clare Weedon, 27, a Systems Integration Manager for Virgin Media, from Addlestone, in Surrey
Ryan McDonald who has been shortlisted for the Mars One mission spoke to the Guardian about the inevitability of the one-way mission.
He said: “The most important thing to do in life is to leave a legacy. A lot of people do that by having a child, having a family. For me this would be my legacy.
“Hundreds of years down the line who is going to know who was the President of the United States? Everyone will remember who were the first four people who stepped onto Mars.”
