After some inventive sleuthing, the Voyager 1 mission team can — for the first time in five months — check the health and status of the most distant human-made object in existence. For the first time since November 2023, NASA’s Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems. The next step is to enable the spacecraft to begin returning science data again. The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space (the space between stars).
