Its Alive! NASAs New Horizons Pluto Probe Wakes Up for Work From 2.9 billion miles away, NASAs New Horizons spacecraft let its handlers know on Saturday that it has awakened from hibernation and is ready for the climax of its nine-year trip to Pluto. The first signals were received at the missions control center at Johns Hopkins Universitys Applied Physics Laboratory in Maryland via a giant radio antenna in Australia just before 9:30 p.m. ET, nearly four and a half hours after it was sent by the piano-sized probe. It takes that long for signals to travel between there and here at the speed of light. Later readings confirmed that New Horizons was fully awake.
