ISEE-3/ICE:
International Sun-Earth Explorer 3's was part of a trio of spacecraft sent into space to study interplanetary space. It was the first spacecraft orbit at a libration point and also the first to detect the solar wind approaching Earth.
It was later renamed International Cometary Explorer and sent to study comet Giacbini-Zinner and comet Halley. When last contacted, the spacecraft was on a trajectory that will bring it close to Earth in August 2014. It could possibly be recaptured, returned to Earth and ultimately be displayed at the Smithsonian Institution.
