Crowdfunding the recovery of a lost spacecraft, Make: Magazine
“The hackers behind the Lunar Orbiter Image Recovery Project have moved on to a different challenge. Not content with images, this time they want to recover a whole spacecraft. The ISEE-3 probe was launched in 1978. After completing it’s original mission–it was the first spacecraft ever to enter a halo orbit at one of the Earth-Sun Lagrangian points–studying the interaction between the Earth’s magnetic field and the solar wind, it was repurposed–leaving its halo orbit. The spacecraft was then sent on its way to intercept Comet Giacobini-Zinner in 1985, and then Comet Halley in 1986 as part of the Halley Armada. Afterwards, left in a heliocentric orbit, it was then used for investigations of coronal mass ejections until 1997 when it was decommissioned by NASA.”
