Ground-based radar technique helps to spot the spacecraft
India’s first lunar probe, Chandrayaan-1, which was considered lost, is still orbiting the moon, NASA scientists have found by using a new ground-based radar technique.
The ISRO lost communication with Chandrayaan-1 on August 29, 2009, almost a year after it was launched on October 22, 2008.
Now, scientists at NASA’s Jet Propulsion Laboratory (JPL) in California have located the spacecraft still circling some 200 km above the lunar surface. “We have been able to detect NASA’s Lunar Reconnaissance Orbiter (LRO) and the Indian Space Research Organisation’s Chandrayaan-1 in lunar orbit with a ground-based radar,” said Marina Brozovic, a radar scientist at JPL and principal investigator for the test project.
