Radar "Eyes"
Radar "Eyes" As the Sun dramatically drops from sight in California’s Mojave Desert, Goldstone’s 70-meter antenna stands poised and ready for work. Part of NASA’s Deep Space Network—used to communicate with planetary spacecraft—Goldstone is one of the world’s two primary facilities set up for planetary radar astronomy. Scientists are using radar to peer into the dark regions of our solar system, discovering and tracking potentially hazardous near-Earth asteroids. JPL/NASA
