BBC News Hangout: Why would you want to live on Mars?

A group of space enthusiasts have spoken to the BBC about space exploration and why it might be worth living on Mars.

Dutch organisation, Mars One, wants to send a group of people to the planet in a bid to build a community of settlers there.

The BBC's Science Editor, David Shukman, took part in a BBC News Google Hangout.

Contributors from as far afield as Arizona, Paris and Mumbai shared their thoughts on a plan for an outpost where people would live - and die - beyond Earth.
