Two NASA WB-57F research aircraft successfully tracked the August 21 solar eclipse as part of a NASA project led by Southwest Research Institute (SwRI) to study the solar corona and Mercury's surface...The team began initial analysis of the data gathered during the flights, showing clear images of the Sun's outer atmosphere and thermal images of Mercury's surface. Initial results are expected to be released in a few months and presented at the fall meeting of the American Geophysical Union in December 2017.
