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.
