Giant NASA Spider Robots Could 3D Print Moon Base

From Ars Techica comes the news that the first Moon base might not be man made. Space architects Tomas Rousek, Katarina Eriksson and Ondrej Doule and scientists from NASA's Jet Propulsion Laboratory (JPL) are cooking up a plan to build giant spider robots to do the construction.

They propose using microwaves, no more powerful than your kitchen's, to melt lunar dust and fuse it into solid blocks and then the giant spider robots (I never get tired of writing those words) would assemble the habitat.

Sound like science fiction? Here's a video of a half-size prototype of the giant spider robot.
