PARIS, Jan. 20 (UPI) -- European scientists say a comet-hunting spacecraft has successfully awakened from a 31-month hibernation to call home and report in.
The Rosetta spacecraft, launched in 2004 on a mission to rendezvous with a comet, study it and place a small probe on its surface, sent a signal that was received by NASA's Goldstone ground station in California at 1:18 p.m. EST, the European Space Agency reported Monday.
