Efforts to resurrect the vintage ISEE-3 space probe have ended disappointingly. The probe was launched by NASA in 1978 to measure solar winds, but decommissioned in 1997 as the craft drifted farther and farther from Earth. A group of former NASA employees launched a $160,000 crowdfunding effort in 2008 to attempt to return the probe to active duty, but despite a promising start earlier this week the mission is largely over. At this point were sort of scratching our heads, says Keith Cowing, a former NASA employee working on the project, in an interview with NPR.
