9 February 2015
Meet the people who’ve volunteered to be on the first manned mission to Mars … and stay there.
Three volunteers are on the shortlist to be among four people on the Mars One programme, the first manned space flight to Mars – a one-way trip that’s effectively a suicide mission. A physics student in the UK, a young doctor from Mozambique and an Iraqi-American woman, all happy to sacrifice their futures for a place in history.
Why do they want to leave Earth, and who are they leaving behind? As the list of potential Mars explorers is whittled down further on 16 February, meet those competing to be the first to land on the Red Planet.

Exactly! I am pretty sure most of them (or their families) thought they might never return…

They often did not return. Many sailors at that time died from scorbut and other diseases, ships were relatively small for stormy weather, etc.

Exactly… So it was a trip with no return as well. Still… I feel it is a bit crazy… Scary… Not sure if I should think the people who volunteer to go to Mars are crazy or brave…
