The Planetary Science Decadal Survey indicated that new ground-based radar systems will be vital research tools for planetary defense and studying planets, moons, asteroids, and other Solar System objects. The National Radio Astronomy Observatory and the Green Bank Observatory are developing new capabilities for the Green Bank Telescope and the Very Long Baseline Array that will meet those needs.
