NASA AIM, short for NASA’s Aeronomy of Ice in the Mesosphere, is a space-based research mission dedicated to studying the highest and least-understood region of Earth’s atmosphere, the mesosphere. The AIM mission specifically focuses on investigating the formation, dynamics, and characteristics of noctilucent clouds (NLCs), also known as polar mesospheric clouds (PMCs), which occur in the mesosphere. Here, you’ll find articles covering the fascinating discoveries, scientific findings, and cutting-edge research emerging from the NASA AIM mission. Stay informed and explore the incredible insights being gained from this unique space-based investigation of our planet’s atmosphere.
