A World of Snowy Dunes on Mars

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

The Eclipse 2017 Umbra Viewed from Space

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
