BBC News Hangout: Your Space Questions 29 April 2013 Last updated at 13:43 As applicants begin signing up for a Dutch organisation's project to send people to live on Mars, many people are once again pondering the future of space exploration. The BBC's Science Editor David Shukman will take part in a BBC News Google Hangout with some of those applicants, to talk about the prospects for people in space. You can join in today from 13:00 GMT. Given the opportunity, would you want to blast off into space? Even if you wanted to travel outside the Earth's atmosphere, would you want to settle on a satellite, or another world? Do you think there should be limits to the exploration of space? What do you want to ask our guests who have put their names down for the Mars One project? In times of economic hardship for many, do you think space exploration is worth the money? The hangout will be live on the BBC News Google+ page, where you will also be able to leave your comments and questions. You can also tweet with #bbcmars, post on the BBC World News Facebook page or send us an email. If you miss the live broadcast, you can see the highlights on World Have Your Say on Friday at 1500GMT on BBC World News.
