NASA to Chase Eclipse with a Pair of WB-57s at 50,000 Feet
Posted by Guy Pirro on 8/11/2017 4:39 PM
Total solar eclipses are unique opportunities for scientists to study the hot atmosphere above the Sun's visible surface. The faint light from the Corona is usually overpowered by intense emissions from the Sun itself. During a total eclipse, however, the Moon blocks the glare from the bright solar disk and darkens the sky, allowing the weaker coronal emissions to be observed. A team led by Southwest Research Institute will use airborne telescopes aboard NASA WB-57 research aircraft to study the solar corona and Mercury's surface during next week's total solar eclipse. The August 21 observations will provide the clearest images to date of the Sun's outer atmosphere. In addition, the scientists will attempt to take the first-ever thermal images of surface temperature variations of the planet Mercury.
