Planetary Defense & Science Will Advance With New Radar on Green Bank Telescope

With less power than a microwave, prototype produced highest resolution images of Moon ever captured from Earth

With a transmitter less powerful than a microwave oven, a team of scientists and engineers used the National Science Foundation’s Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA) to make the highest-resolution radar images of the Moon ever collected from the ground, paving the way for a next-generation radar system to study planets, moons, and asteroids in the Solar System.
