The 40th Anniversary of the Apollo moon landings has provoked a flurry of recent articles and debate about the future of space exploration. Some argue we've lost the momentum, and this seems likely; there's no such thing as a 'space race' anymore, no deadline to beat the Russians like before. Landing on the moon was an incredible feat back in the late 60s, but is there the same hunger to do it all again, but only further this time, perhaps to Mars?

In a way, landing on the moon smashed through the frontier of our collective imagination. What was worshipped for millennia as a god now had Alan Shepard smacking golf balls on its surface in 1971. Anything is possible. But what next for space exploration? What will our own 'one giant leap for mankind' moment be?

• Does thinking about space exploration fire your imagination or does it leave you cold, a 'waste of money'?

• Do you think we'll get to Mars and if so, when? Also, what's the point of going? Indeed, is there any point to space travel at all?

• Just how likely is it that we'll replicate the spirit of the American frontiersmen and really go for it with a super long-haul journey to say, Alpha Centuri?

• Suspending disbelief for a minute, if members of the public were asked, could you imagine yourself volunteering for a long-haul space project, a one-way ticket only job, never to return?

• Would it be ethically wrong for a couple to give birth on a one-way space journey, therefore condemning the new-born to never seeing Earth again?

• Do you think we'll be going to the Moon more often in the near future and perhaps staying there, mining its minerals? Might territorial wars be fought over the Moon in the way it's been suggested we might scrap for mineral rights in the Arctic?

• Is space exploration actually a pre-cursor to a time in the future when we actually have to begin vacating the Earth having exhausted all of its resources?
