    "description": "ISEE-3 (International Sun-Earth Explorer) was a mission launched in 1978 and was the first spacecraft to orbit the Earth-Sun L1 (Wikipedia: Lagrange) point.Its primary mission complete, it was renamed the International Cometary Explorer (ICE) and its orbit was altered to measure the electrodynamic environments of comets Giacobini-Zinner and Halley (Wikipedia).  It subsequently entered a solar orbit which sent it inside and outside the orbit of the Earth.In mid-2014, its current orbit will have ICE pass close to the Earth. || ",
