This 12-frame mosaic provides the highest resolution view ever obtained of the side of Jupiter’s moon Europa that faces the giant planet. It was obtained on Nov. 25, 1999 by the camera onboard the Galileo spacecraft, a past NASA mission to Jupiter and its moons which ended in 2003. via NASA http://ift.tt/1dv2LVx

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 via NASA http://ift.tt/1Q1m9oI

Equipment and data from the SpinSat investigation returns to Earth today, May 21, 2015, with splashdown of the sixth SpaceX cargo resupply mission to the International Space Station. This Nov. 28, 2014 photograph by NASA astronaut Terry Virts captures the predeploy of SpinSat, which was launched into orbit from the station. via NASA http://ift.tt/1KmpTCL

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. via NASA http://ift.tt/1AZlddP

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. via NASA http://ift.tt/1F7sPi5
