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
