The Lunacy of Secrecy: 30 Years Since Mission 51C (Part 2)

Since the conception of the Manned Spaceflight Engineer (MSE) program, the intent was to fly a dedicated officer aboard each classified flight. For Mission 51C, it would be Air Force Major Gary Payton (back left). The other NASA crew members were Loren Shriver (front left) and Ken Mattingly (front right), with Jim Buchli and […]

NASA's Van Allen Probes Going Strong After Two Years of Studying Earth's Radiation Belts

NASA’s Van Allen Probes orbit through two giant radiation belts surrounding Earth. In the time since launching two years ago, the probes have discovered a third radiation belt, and other observations have helped explain how particles in the belts can be sped up to nearly the speed of light.Image Caption and Credit: NASA
