The Aeronomy of Ice in the Mesosphere (AIM or Explorer 90) is a NASA satellite launched in 2007 to conduct a planned 26-month study of noctilucent clouds (NLCs).[2] It is the ninetieth Explorer program mission and is part of the NASA-funded Small Explorer program (SMEX).
In March 2023, NASA announced that battery power on the spacecraft had declined below the level needed to sustain operation.[3]
