A new radar system being developed by the National Radio Astronomy Observatory and the Green Bank Observatory will transmit powerful radar signals from the Green Bank Telescope (top right panel) and, in this illustration, bounce those signals off the Moon (middle right). The reflected signal can be received by antennas of the Very Long Baseline Array, in various locations across the U.S., Hawaii, and the Virgin Islands (bottom right). The combination of antennas acts as a giant, high-resolution radar imaging system.
