After several attempts, the project team ISEE-3 Reboot announced that it managed to run the thrusters of the ISEE-3 (International Sun / Earth Explorer 3) space probe, also known as ICE (International Cometary Explorer). On July 2, the team was able to activate the thrusters but then they gave no other signs of life. After several days of trying to identify the problem, this probe now 36 years old seems to really go back to being operational.
