Latest Aeronomy of Ice in the Mesosphere Stories
When you think about the North and South poles, they seem to be worlds apart. They are separated by four oceans, six continents, and more than 12,000 nautical miles. However, new data shows they may not be as far apart as one might think.
First spotted in 1885, silvery blue clouds sometimes hover in the night sky near the poles, appearing to give off their own glowing light.
Noctilucent clouds (NLCs), tenuous cloud-like phenomena that form every summer in the skies above the North Pole, are forming earlier than usual.
In October 2011, a NASA-funded sounding rocket traveled up through these ice clouds for a five minute trip to collect some of the first data on just how much smoke exists, what size the particles are, what electrical charge they have, and whether they could indeed form these shimmering clouds as predicted.
The last space shuttle flight took place on July 8, 2011, sending Atlantis into space for its thirty-third, and final mission, releasing 350 tons of water vapor exhaust.
When noctilucent clouds (NLCs) first appeared in the 19th century, they were a high-latitude phenomenon.
High up in the sky near the poles some 50 miles above the ground, silvery blue clouds sometimes appear, shining brightly in the night.
NASA's Aeronomy of Ice in the Mesosphere (AIM) satellite has captured five complete polar seasons of noctilucent (NLC) or "night-shining" clouds with an unprecedented horizontal resolution of 3 miles by 3 miles.
GREENBELT, Md., Dec. 15 /PRNewswire-USNewswire/ -- NASA's Aeronomy of Ice in the Mesosphere (AIM) satellite has captured five complete polar seasons of noctilucent (NLC) or "night-shining" clouds with an unprecedented horizontal resolution of 3 miles by 3 miles.
WALLOPS ISLAND, Va., Sept. 9 /PRNewswire-USNewswire/ -- A rocket experiment that may shed light on the highest clouds in the Earth's atmosphere will be conducted Sept.
