A new satellite to study clouds of water ice that form at the edge of the atmosphere successfully launched on 25 April.
Over at least the next 2 years, NASA's Aeronomy of Ice in the Mesosphere (AIM) mission will investigate polar mesospheric clouds (PMCs, also known as noctilucent or ‘night shining’ clouds), which form about 80 kilometers above the Earth's surface in the mesosphere over the polar regions during the polar summer. The clouds are visible only at night when illuminated by sunlight from beyond the horizon. Since PMCs were discovered in 1885, they have increased in brightness and prevalence and have been forming at lower latitudes.
