As hurricane Earl is getting ready to hit the US East Coast, NASA is watching from the skies, using its large high tech fleet of aircraft and satellites. Yesterday Earl was a category 3 storm with 125 mph winds. But in a single day, it’s reached category 4 140 mph winds.
NASA scientists are flying airplanes into this swirling mass, measuring the hurricane’s wind speeds, precipitation and more. As part of NASA’s GRIP program — Genesis and Rapid Intensification Processes — a NASA DC-8 flew through Earl’s eye six times as the hurricane intensified from a Category 2 to a Category 4 storm.
Meanwhile, an ISS crew member used a digital camera with a 50mm lens to take the above photo, from a much safer distance.
