NASA's Plucky Deep Impact Probe Feared Lost
Scientists fear NASA's comet-chasing Deep Impact spacecraft may be lost in space after a software glitch cut off communications between the aging space probe and befuddled engineers on Earth.
NASA last heard from the distant spacecraft on Aug. 8, and efforts to restore contact with Deep Impact have produced no results. Engineers will continue to uplink commands to the probe in an attempt to reestablish communications, the agency said in a press release Tuesday.
Officials blame Deep Impact's problem on a software glitch, according to Michael A'Hearn, the mission's principal investigator from the University of Maryland in College Park.
