Firms interested in trying for the prize have until the end of 2012 to mount their Moonshot

Anyone fancy a crack at this?

Cheers

VERY VERY rough figures - but that would suggest a mass fraction of approx 75-90% to achieve 6km/sec delta V. Staging might help (at that scale?) - so you've got something like 175kg to 70kg of vehicle structure, engines, systems, fuel tanks ( carrying 600kg of fuel). What's left for the actual rover? To coin a phrase, roughly 9/10ths of 4/5ths of 'f' all
