NASA’s Operation IceBridge is flying its summer Arctic land ice campaign in Greenland, continuing its measurements of the Greenland Ice Sheet and its outlet glaciers. This photograph from the mission was taken on Aug. 29, 2017, from 28,000 feet, looking north while surveying Nioghalvfjerdsbrae (79 N) Glacier in northeast Greenland. via NASA http://ift.tt/2x5KGKi

A NASA F-18 jet takes off from the agency’s Shuttle Landing Facility at NASA’s Kennedy Space Center in Florida on Aug. 23, 2017. The F-18 jets fly at supersonic speeds while agency researchers measure the effects of low-altitude turbulence caused by sonic booms, part of NASA’s Sonic Booms in Atmospheric Turbulence, or SonicBAT II Program. via NASA http://ift.tt/2xGKj62

On August 25, 2017, NASA astronaut Jack Fischer photographed Hurricane Harvey from the cupola module aboard the International Space Station as it intensified on its way toward the Texas coast. The Expedition 52 crew on the station has been tracking this storm for the past two days and capturing Earth observation photographs and videos. via NASA http://ift.tt/2wOiueR

It was spring in the Northern hemisphere when this image was taken on May 21, 2017, by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter. Over the winter, snow and ice have inexorably covered the dunes. Unlike on Earth, this snow and ice is carbon dioxide, better known to us as dry ice. via NASA http://ift.tt/2wBqmRy

As millions of people across the United States experienced a total eclipse as the umbra, or moon’s shadow passed over them, only six people witnessed the umbra from space. The space station crossed the path of the eclipse three times as it orbited above the continental United States at an altitude of 250 miles. via NASA http://ift.tt/2v5PxeW
