You've heard about the Space Shuttle 'poking holes' in our atmosphere and what effects that might have on everything from pollution to solar radiation.
Well here's the latest...the Naval Research Labratory has found that the exhaust plume found it's way to Antarctica to create Antarctic polar mesospheric clouds. The news release states that the, "key piece of data that confirmed the plume's arrival in Antarctica was the ground-based observation of iron atoms near 110 km. The presence of iron at this altitude originally perplexed scientists because there is no known natural source there. The data imply that iron ablated, or vaporized, by the main engines of the Shuttle was transported along with the water plume, arriving in Antarctica three to four days after the January 2003 launch."
Sounds familiar
