Our World: Digging in Moon Dirt

A NASA video presentation: Our World: Digging in Moon Dirt. NASA has plans to set up an outpost on the moon and one of the issues they are facing is how to dig dirt on the moon. Unlike dirt found here on earth, moon dirt is razor sharp and very fine so researchers must figure out a way to design a machine that can dig moon dirt without destroying the machine. This NASA video takes you behind the scenes at the NASA lunar backhoe competition where researchers compete to find out who has made the most efficient machine.
