NASA's ISEE-3 was launched in 1977 and sent data home for 20 years. Recently, NASA discovered the abandoned satellite is still transmitting data, and turned over the controls to a group of citizen scientists. ISEE-3 zooms by the moon tomorrow, and thanks to a new Google project, you can ride along at home.
When citizen scientists first discovered that ISEE-3 was still out there transmitting data, they put together a crowdfunding project and took over
an abandoned McDonalds a former McDonalds at NASA's Ames Research Facility, hoping to regain control of the satellite's flight path and send it on new missions. Unfortunately, ISEE-3's propulsion systems are shot.
