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."
