August 16, 2002 Laurel, Maryland - Late this afternoon at Johns Hopkins University's Applied Physics Laboratory (JHUAPL), Dr. Robert Farquhar, Mission Director for the Comet Nucleus Tour (CONTOUR), teleconferenced with reporters about the status of the missing CONTOUR spacecraft. CONTOUR's STAR 30 solid-propellant rocket motor was programmed to ignite at 4:49 a.m. EDT yesterday, August 15, to launch the probe out of Earth orbit onto a trajectory to study two or three comets over the next few years. At that burn time, CONTOUR was over the Indian Ocean at 140 miles (225 kilometers), too low for NASA's Deep Space Network stations to track the spacecraft during the burn. All systems seemed to be OK going into the burn, but 45 minutes later when the JHUAPL mission operations team tried to regain contact with the probe, no signal was received.
