NASA scientists have discovered a way to craft very large mirrors using carbon nanotubes, some epoxy, a little bit of aluminum, and large quantities of lunar dust. They say the technique will allow the construction of massive telescopes on the moon without the expense and risk of transporting the mirrors from Earth. Douglas Rabin of the Goddard Space Flight Center is quoted saying, "Our method could be scaled-up on the moon, using the ubiquitous lunar dust, to create giant telescope mirrors up to 50 meters in diameter." While this breakthrough was relatively cheap, NASA is currently offering up to $10 million for other good lunar research projects.
