Of interest to us, but semi-orthogonal to the Google Lunar X Prize
Space Florida is running the Nanosat Launcher Challenge. This is a competition to orbit one kilogram nanosatellites: you must launch and orbit two seperate nanosats within a seven day period and currently there is a first, second and third prize. Space Florida has just released their draft rules (pdf) for public commentary.
For most teams, this has nothing to do with the Google Lunar X Prize. Team Phoenicia has run two separate Nanosat Launcher Challenge Seminars in November 2010 and November 2011. We are building rockets and selling engines and components to various competitors while not competing ourselves (the moon is hard enough, thanx!). The reason that we are building components and equipment is that we are using the funds raised to help pay for our Moon landing bid. Hence, the tie in.
That said, we'd recommend that everyone who can, does go over and read the new rules. This is a rare chance to influence those rules for a prize competition that is as exciting in its own way as the Google Lunar X Prize. We know that the feedback gets listened to. We fed a lot of information into NASA and Space Florida prior to the draft rules being settled on: there are nontrivial incorporations of what we recommended. So, by all means, have at them!
