Vintage NASA Probe Out of Gas, But Still Alive, Private Team Says, Space.com

"Alas, ISEE-3 spacecraft, we almost caught you. Attempts to move a 36-year-old NASA probe closer to Earth have failed, but only because the vintage spacecraft is simply out of gas, according to the team of volunteer engineers now controlling the spacecraft. The spacecraft, called the International Sun-Earth Explorer 3 (ISEE-3), has run out of vital nitrogen gas needed to pressurize its propulsion system, according the private team of engineers. The team, which calls itself the ISEE-3 Reboot Project, has spent recent weeks puzzling through an issue that shut down attempts to send the ISEE-3 spacecraft on a new trajectory on July 10. With all options exhausted, the team now plans to do science in a different location instead."
