New Satellites Target Space Weather Threat

WHO’S AFRAID OF KILLER ELECTRONS?  “Killer electrons” from the Van Allen Belts are raining down on Earth’s atmosphere. Last Saturday, a Delta II rocket blasted off at dawn from Vandenberg AFB in California. Soon thereafter NASA reported the successful deployment of the ICESat-2 satellite, designed to make 3D laser images of Earth’s surface. Here’s what…

Giant 'space hurricanes' may affect satellites

Solar wind impacts on giant ‘space hurricanes’ may affect satellite safety From EMBRY-RIDDLE AERONAUTICAL UNIVERSITY Could the flapping of a butterfly’s wings in Costa Rica set off a hurricane in California? The question has been scrutinized by chaos theorists, stock-market analysts and weather forecasters for decades. For most people, this hypothetical scenario may be difficult…
