NASA’s Parker Solar Probe aims to fly closer to the sun like never before

Associated Press  

NEW YORK — A NASA spacecraft aims to fly closer to the sun than any object sent before. Plans call for Parker on Tuesday to hurtle through the sizzling solar atmosphere and pass within a record-breaking 3.8 million miles of the sun’s surface. At that moment, if the sun and Earth were at opposite ends of a football field, Parker “would be on the 4-yard line,” said NASA’s Joe Westlake. Parker planned to get more than seven times closer to the sun than previous spacecraft, hitting 430,000 mph at closest approach. Scientists hope to better understand why the corona is hundreds of times hotter than the sun’s surface and what drives the solar wind, the supersonic stream of charged particles constantly blasting away from the sun.
