A group of citizen scientists can take over a 36-year-old decommissioned robotic space probe that will fly by the Earth in August, NASA says.
Launched in 1978, the International Sun/Earth Explorer-3 (ISEE-3) spacecraft studied how the stream of charged particles flowing from the sun, the so-called solar wind, interacts with Earth's magnetic field.
After completing its primary mission, the probe was given a new name, the International Comet Explorer, and new targets to study, including the famed Halley's Comet as it passed by Earth in March 1986.
