Title:
Aurora from Space
Explanation:
From the ground, spectacular auroras seem to dance [ http://science.nasa… gallery_01mar03.html ] high above. But the International Space Station (ISS [ http://antwrp.gsfc.… ]) orbits at nearly the same height as many auroras [ http://www.explorat… auroras/ ], sometimes passing over [ http://antwrp.gsfc.… ] them, and sometimes right through them. Still, the auroral electron [ http://www.aip.org/… ] and proton [ http://antwrp.gsfc.… ] streams pose no direct danger to the ISS [ http://spaceflight.… ]. In 2003, ISS Science Officer Don Pettit [ http://www.jsc.nasa… ] captured the green aurora, pictured above [ http://science.nasa… 24mar_noseprints.htm ] in a digitally sharpened image. From orbit, Pettit reported [ http://spaceflight.… spacechronicles.html ] that changing auroras [ http://www.geo.mtu.… ] appeared to crawl around like giant green amoebas [ http://www.microsco… amoeba.html ]. Over 300 kilometers below, the Manicouagan Impact Crater [ http://antwrp.gsfc.… ] can be seen in northern Canada, planet Earth.
