Firms interested in trying for the prize have until the end of 2012 to mount their Moonshot Anyone fancy a crack at this? Cheers Brian -------------------- "There are 10 types of people in the world - those who understand binary code, and those who don't."

On paper it's a bit better than a cubesat.
If you can get 670kg to LEO, then you need a further 5.7km/s of dV to the lunar surface. Using hypergolics (for all the right reasons) and a realistic Isp means that the dry weight of the package landed on the surface could be around 80 to 100kg. Not too shabby. Andy Edit: just seen Doug's "no you can't". I'm not sure it's as cut-and-dried as that. |

QUOTE (AndyG @ Sep 14 2007, 02:25 PM)  dry weight of the package landed on the surface How much of that is fuel tankage, engines, plumbing, basic structure etc etc. My bad-maths said something like 70-170kg on the surface - so your proper maths does do a better job  But given the demands of the prize ( 500m, HDTV ) with the landed payload...I just don't see it as possible. Would a hugely optimistic figure for the 'dead' mass of the vehicle be something like 40kg? Leaving a 30kg vehicle for power, cdh, >1mbps downlink caperbility, and sufficient mobility to drive across the moon. For $27m plus whatever else you can generate from it. I just don't think it's feasable. I would love.. and I mean absolutely LOVE to be proven wrong - a rover on the moon would be utterly fantastic. I just don't see this $30m as making a whole chunk of difference in terms of the likelyhood of it being done privately in the next 5 years.Doug |
