• The Atmospheric Imaging Assembly (AIA) instrument on NASA’s Solar Dynamics Observatory images the solar atmosphere in multiple wavelengths to link changes in the surface to interior changes. When AIA images are sharpened a bit, such as this AIA 171Å channel image, the magnetic field can be readily visualized through the bright, thin strands that ar

  • A NASA F-15D flies chase for the G-III Adaptive Compliant Trailing Edge (ACTE) project. The ACTE experimental flight research project is a joint effort between NASA and the U.S. Air Force Research Laboratory to determine if advanced flexible trailing-edge wing flaps can both improve aircraft aerodynamic efficiency and reduce airport-area noise.

  • On May 13, 1992, following the successful capture of the Intelsat VI satellite, three astronauts continue moving the 4.5 ton communications satellite into the space shuttle Endeavour’s cargo bay. The sections of Earth which form the backdrop for the scene are blanketed with thousands of square miles of clouds.

  • From the International Space Station, NASA astronaut Terry Virts took this photograph of an early morning sunrise over the Grand Canyon and posted it to social media on May 10, 2015. Because the station completes each trip around the globe in about 92 minutes, the crew experiences 16 sunrises and sunsets each day.

  • NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured these images of a significant solar flare – as seen in the bright flash on the left – peaking at 6:11 p.m. EDT on May 5, 2015. Each image shows a different wavelength of extreme ultraviolet light that highlights a different temperature of material on the sun.

  • Fifty-four years ago on May 5, 1961 only 23 days after Yuri Gagarin of the then-Soviet Union became the first person in space, NASA astronaut Alan Shepard launched at 9:34 a.m. EDT aboard his Freedom 7 capsule powered by a Redstone booster to become the first American in space. His historic flight lasted 15 minutes, 28 seconds.
