Spoiler alert: they didn't succeed (from Wikipedia) On May 29, 2014, two-way communication with the spacecraft was reestablished by the ISEE-3 Reboot Project, an unofficial group[7] with support from the Skycorp company.[8][9][10] On July 2, 2014, they fired the thrusters for the first time since 1987. However, later firings of the thrusters failed, apparently due to a lack of nitrogen pressurant in the fuel tanks.[11][12] The project team initiated an alternative plan to use the spacecraft to "collect scientific data and send it back to Earth",[13] but on September 16, 2014, contact with the probe was lost.[14]
