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 SciTechDaily.com 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.
The sky isn’t falling, but scientists have found that parts of the upper atmosphere are gradually contracting in response to rising human-made greenhouse gas emissions….
Noctilucent clouds form so high in the atmosphere that they continue to reflect sunlight hours after sunset, creating a shimmering nighttime spectacle. Clouds illuminated during…
Launched in 2007, the Aeronomy of Ice in the Mesosphere, or AIM, mission is the first detailed exploration of Earth’s unique and elusive clouds that…
Summer in Antarctica is marked by days in which the Sun never sets, balmy temperatures that hover as high as freezing, and electric-blue clouds of…
Every summer in the Northern Hemisphere, electric blue streaks form high in the atmosphere. These seasonal clouds typically lurk about 80 kilometers (50 miles) overhead…
Ice-blue clouds are drifting high above the Arctic, which means the Northern Hemisphere’s noctilucent cloud season is here. NASA’s Aeronomy of Ice in the Mesosphere…
Data from NASA’s Aeronomy of Ice in the Mesosphere spacecraft shows the sky over Antarctica is glowing electric blue due to the start of noctilucent,…
This composite image shows noctilucent clouds over the Arctic captured by NASA’s Aeronomy of Ice in the Mesosphere Spacecraft. In the late spring and summer,…
