NASA asteroid mission creates atlas of surface of protoplanet Vesta
PASADENA, Calif., Sept. 16 () -- NASA says a photographic atlas of the giant asteroid Vesta, created by the agency's Dawn unmanned space probe as it circled the protoplanet, can be seen online.The maps are mostly at a scale about that of regional road maps of Earth, with every inch of map equivalent to a little more than 3 miles of asteroid, NASA's Jet Propulsion Laboratory in Pasadena,[url=http://www.panyam.com/]cheap gucci shoes[/url], Calif., reported.The atlas was created from mosaics of 10,000 images taken by Dawn's framing camera instrument at a low altitude of about 130 miles from the surface of the asteroid, which has a diameter of about 326 miles, researchers said."Creating the atlas has been a painstaking task -- each map sheet of this series has used roughly 400 images," researcher Thomas Roatsch, who presented the images at the European Planetary Science Congress 2013 in London,[url=http://www.tymarc.com/]christian louboutin outlet[/url], said."The atlas shows how extreme the terrain is on a body the size of Vesta. In the south pole projection alone, the Severina crater contours reach a depth of 11 miles; just over 60 miles away, the mountain peak towers about 4 miles high."The Vesta images can be views online at [link widoczny dla zalogowanych]
