Build a moon telescope... with moon dust!

''
A lunar telescope the same size as Hubble (2.4 meters across) would be a major astronomical research tool. One as big as the largest telescope on Earth—10.4 meters across—would see far more than any Earth-based telescope because the Moon has no atmosphere. But why stop there? In the Moon's weak gravity, it might be possible to build a telescope with a mirror as large as 50 meters across, half the length of a football field—big enough to analyze the chemistry on planets around other stars for signs of life.

"If we lift all materials from Earth, we're limited by what a rocket can carry to the Moon," Chen explains. "But on the Moon, you're absolutely surrounded by lunar dust"—a prized natural resource in the eyes of Chen, an expert in composite materials.

he mixed NASA's simulated lunar dust called JSC-1A Coarse Lunar Regolith Simulant with epoxy and a small quantity of carbon nanotubes, a relatively recently discovered form of carbon that has many unusual and useful properties. The result? "It came out as hard, dense, and strong as concrete."
