A NASA satellite has captured the first occurrence this summer of mysterious shiny polar clouds that form 50 miles above Earth's surface. The first observations of these "night-shining" clouds by a satellite named "AIM" which means Aeronomy of Ice in the Mesosphere, occurred above 70 degrees north latitude on May 25. People on the ground began seeing the clouds on June 6 over Northern Europe. AIM is the first satellite mission dedicated to the study of these unusual clouds. These mystifying...

WASHINGTON - NASA is preparing to launch the Aeronomy of Ice in the Mesosphere (AIM) spacecraft, the first mission dedicated to exploration of mysterious ice clouds that dot the edge of space in Earth's polar regions. These clouds have grown brighter and more prevalent in recent years and some scientists suggest that changes in these clouds may be the result of climate change. The first opportunity for launch is on Wednesday, April 25 from Vandenberg Air Force Base, Calif., aboard a Pegasus...

CHAMPAIGN, Ill. -- A burst of mesospheric cloud activity over Antarctica in January 2003 was caused by the exhaust plume of the space shuttle Columbia during its final flight, reports a team of scientists who studied satellite and ground-based data from three different experiments. The data also call into question the role these clouds may play in monitoring global climate change. "Our analysis shows that the Columbia's exhaust plume approached the South Pole three days after launch," said...

(Washington, DC "¢ July 6, 2005) "” A new study, funded in part by the Naval Research Laboratory (NRL) and the National Aeronautics and Space Administration (NASA) reports that exhaust from the space shuttle can create high-altitude clouds over Antarctica mere days following launch, providing valuable insight to global transport processes in the lower thermosphere. The same study also finds that the shuttle's main engine exhaust plume carries small quantities of iron that can be...
