be used to build a landing site for a moon outpost. In order to be efficient
a landing pad would have to be close to any structures created, but without
an atmosphere to slow down the lunar sand it would sandblast the outpost,
creating the need for some sort of protection. By using small robots to
either build protective berms or collect rocks to "pave" a landing pad, NASA
hopes to provide protection against the sand-blasting effects of a landing
on the moon."
