As the Sun Rises, NASA's Global Hawk is Being Prepared for Flight


Hot summer days in Southern California’s Antelope Valley force many aircraft operations to start early in the morning before the sun rises. On a back ramp at Armstrong Flight Research Center on Edwards Air Force Base, a NASA Global Hawk goes through testing of its communication components and satellite connection links in preparation for flight. via NASA http://ift.tt/2sX9zUG

Hubble Uses Gravitational Lens to Capture Disk Galaxy


By combining the power of a "natural lens" in space with the capability of NASA's Hubble Space Telescope, astronomers made a surprising discovery—the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang. via NASA http://ift.tt/2t2PLCd

The White Cliffs of 'Rover'


This image was acquired by the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter on April 18, 2017, at 14:04 local Mars time. It reminded the HiRISE team of the rugged and open terrain of a stark shore-line, perhaps of the British Isles. via NASA http://ift.tt/2rGyUke

Visualization of the August 21, 2017 Total Solar Eclipse


On August 21, 2017, the Earth will cross the shadow of the moon, creating a total solar eclipse. Eclipses happen about every six months, but this one is special. For the first time in almost 40 years, the path of the moon's shadow passes through the continental United States. via NASA http://ift.tt/2rRirhl

Deployment of the Space Station's Roll Out Solar Array Experiment


Over the weekend of June 17-18, engineers on the ground remotely operated the International Space Station's Canadarm2 to extract the Roll Out Solar Array experiment from the SpaceX Dragon resupply ship. The experiment will remain attached to the Canadarm2 over seven days to test this advanced, flexible array that rolls out like a tape measure. via NASA http://ift.tt/2tp28oW

Webb Telescope Set for Testing in Space Simulation Chamber


NASA’s James Webb Space Telescope sits in front of the door to Chamber A, a giant thermal vacuum chamber located at NASA’s Johnson Space Center. The telescope will soon be moved into the chamber, where it will spend a hot Houston summer undergoing tests at sub-freezing cryogenic temperatures. via NASA http://ift.tt/2sKRZWE

Celebrating Flag Day


NASA astronaut Jack Fischer took this photograph of an American flag in one of the windows of the International Space Station's cupola, a dome-shaped module through which operations on the outside of the station can be observed and guided. Throughout NASA's history, spacecraft and launch vehicles have always been decorated with flags. via NASA http://ift.tt/2rsJ3EW
