NASA's Jet Propulsion Laboratory in Pasadena, California, has successfully detected the Chandrayaan 1 spacecraft orbiting the moon -- one active, and one dormant. The discovery was made by NASA scientists with new technological application of interplanetary radar. Finding derelict spacecraft and space debris in Earth's orbit can be a technological challenge. Detecting these objects in orbit around Earth's moon is even more difficult. However, with the new technological application of interplanetary radar, the scientists at JPL successfully located the two spacecraft orbiting the Moon. The researchers believe that the new technique could assist planners of future Moon missions.
