How NASA Makes Super High Resolution Images of Earth

Last month we shared an ultra-high resolution image of Earth with you, courtesy of NASA’s Suomi NNP satellite. Now we’re back to highlight the process by which NASA generates such beautiful images.

Wired Magazine shares a great overview of how the satellite creates such fantastic and high-resolution images. They write:

How were these highly detailed images created? The satellite flies 512 miles above the Earth, but the images appear as if they were taken from a much higher perspective: an altitude of 1,242 for the first image and 7,918 miles for the second. This little trick was accomplished by stitching together data from several orbits, creating an image that appears to be “pulled back.”

NASA launched the 4,600-pound Suomi in October to remotely sense variations in the Earth’s oceans, continents, and atmosphere and get a better understanding of climate change. It passes directly from pole to pole 14 times a day, imaging 1,865-mile swaths of our planet with each trip.

Hit up the link below for more information on the process.

When he's not documenting mods and hacks he's doing his best to make sure a generation of college students graduate knowing they should put their pants on one leg at a time and go on to greatness, just like Bruce Dickinson.
