NASA’s AIM mission is coming to an end after 15 years in orbit. The government said Thursday that it was ceasing operational assistance for the spacecraft owing to a battery power failure in a brief blog post seen by Gizmodo. AIM’s battery problems were initially discovered by NASA in 2019, but the spacecraft was still returning “significant amounts of data” to the planet. NASA reports that AIM has stopped responding as a result of a recent decrease in battery power. In case the spacecraft reboots, the AIM team will continue to keep an eye on it for another two weeks, but based on NASA’s report, the agency isn’t holding its breath.
