US planetary radar may get a boost from Green Bank Observatory
When Green Bank began planning its demonstration project, it had never sent radar signals itself but had worked as a receiver for both of the major U.S. planetary radar transmitters. Planetary scientists will continue to feel that loss, even if the Green Bank project does turn into a full-fledged transmitter. And it's unclear whether the loss of Arecibo will influence the fate of the Green Bank project. But before Green Bank committed to a full-fledged planetary radar project, astronomers wanted to test the waters. The Green Bank Telescope is the largest fully steerable radio telescope in the world.
