Arthur Walker, Jr, had a big, often-overlooked influence in space science. He pioneered using x-rays to study activity on the Sun, led the Challenger investigation, and opened opportunities for underrepresented groups in astronomy. https://skyandtelescope.org/astronomy-resources/famous-astronomers/arthur-b-c-walker-ii-x-ray-astrophysicist/ #Juneteenth #BlackInStem

Today's SOHO and TRACE space solar observatories build on work done by Arthur Walker, Jr. His first PhD student was his most famous: Sally Ride. But he also quietly used his mentoring to improve diversity in the field. http://www.math.buffalo.edu/mad/physics/walker_arthurbc.html #science #diversity

MSSTA's first flight was on May 13th, 1991 at 19:03 UT. The telescopes were carried to an altitude of 230 km and remained out of the lower atmosphere for approximately 6 minutes. During this time photographs were taken of the Sun and its outer atmospheric layers, the chromosphere and corona. Images obtained with MSSTA span the wavelength range from Lyman-Alpha emission at 1216 Å to a Si XII emission line at 44 Å.
