Great Shot: Mother Earth in High-Def

NASA’s High-Res ‘Blue Marble’ Image is Sharpest Ever


U.S Download old games for free. space agency NASA has released the highest-resolution images ever taken of Earth, capturing in a single view everything from vast deserts to swirling weather systems to polar icecaps zoom videobellen downloaden windows.


The images, one of East Africa and Asia, and the other of North and Central America, are eye-popping.

Not since 1972, when the Apollo 17 astronauts snapped the first famous “Blue Marble” photo, has an image of Earth from space created such buzz paypal transaktionen herunterladen. NASA recently posted the images on the photo-sharing site Flickr, where they’ve gone viral winrar download for free german full version.


Data for the images was beamed down from the mini-van-sized Suomi NPP satellite, which is whipping around the planet in a polar orbit once every 102 minutes at an altitude of 512 miles seriesjunkies complete staffel download. That’s not tree-top level, but for a satellite it’s considered low and fast. Telecommunications satellites, typically parked in geostationary orbits, look down from a lofty 22,236 miles herunterladen. The Apollo shot was snagged from 28,000 miles away.




NASA Goddard Space Flight Center scientist Norman Kuring, who created the images, said that he did his data crunching on a custom-built 64-bit Linux desktop system powered by an Intel Core 2 Quad CPU lg smartphone bilder herunterladen. “It’s just a grey box by my desk,” he said.


Kuring says his Intel-based machine began chewing through the tens of gigabytes of raw satellite data for each image when he went home to eat dinner omsi 2 herunterladen. About 4 hours later the job was done.


Using GIMP and other open-source image processing software, Kuring used his system to stitch together multiple bands of color and infrared data from satellite images shot during 6 separate Earth orbits download pictures instagram. The result is an utterly seamless mosaic of Earth, floating in the black void of space.
