Day 2. London. Sunshine.

Clare Weedon/Alison/Styx

First day interviewing the Mars One explorers and Kirsty has really come round to the idea.

"I think it's opened my eyes to the idea that what they're doing is a selfless act."

Clare likes chasing storms. Alison thinks about building a new culture. 

We've crossed London several times, on trams & trains, and now we're about to cross the river Styx in a small, partly-submerged coffin on wheels.
