Four teams of backyard inventors vied to dig as much simulated lunar soil as possible in half an hour at NASA's Regolith Excavation Challenge on Saturday, but no one scooped up the $125,000 first prize.
The teams were trying to excavate 150 kilograms of the mock soil, or "regolith", using no more than 30 watts of power – enough to run a refrigerator light bulb – and dump the soil in a bin. Technology Ranch of Pismo Beach, California, was the only one to run 30 minutes on its first attempt, scooping up 75 kilograms (although 10 kilograms missed the collection box). Intended as a two-year programme, the top prize for the second year of the competition was originally going to be $250,000. But this year's unclaimed prize will be added to it to make a total award of $375,000 in 2008.
