This Earth observation composite image from the International Space Station captures morning sunglint and low clouds over the central Pacific Ocean. The image was put together at the Johnson Space Center in Houston, from a series of photographs taken by Expedition 47 Commander Jeff Williams on March 25, 2016.
A prototype 13-kilowatt Hall thruster is tested at NASA's Glenn Research Center in Cleveland. This prototype demonstrated the technology readiness needed for industry to continue the development of high-power solar electric propulsion into a flight-qualified system.
A view from below in High Bay 3 inside the Vehicle Assembly Building at NASA’s Kennedy Space Center shows three work platforms installed for NASA’s Space Launch System (SLS) rocket. The platforms will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1.
One of dozens of high-powered rockets lifts off on April 16, 2016, during NASA's 16th annual Student Launch challenge, held near Marshall Space Flight Center in Huntsville, Alabama from April 13-16. Nearly 50 middle and high school, college and university teams from 22 states competed in the challenge.
A sinuous feature snakes northward from Enceladus' south pole like a giant tentacle.
This image of early ice breakup of the Beaufort Sea, north of Alaska, was taken by the Suomi NPP satellite's Visible Infrared Imaging Radiometer Suite (VIIRS) instrument infrared channel, at around 1148 UTC on April 13, 2016.
The rear wheels of the space shuttle orbiter Columbia touched down on Rogers dry lake at Edwards Air Force Base, NASA's Armstrong Flight Research Center (then Dryden), California, to successfully complete a stay in space of more than two days. Astronauts John W. Young, STS-1 commander, and Robert L. Crippen, pilot, were aboard the vehicle.
Expedition 47 Commander Tim Kopra of NASA captured this brightly lit night image of the city of Chicago on April 5, 2016, from the International Space Station. Kopra (@astro_tim) wrote, "#Goodnight #Chicago from @Space_Station. #CitiesFromSpace"
An Air Force Test Pilot School T-38C passes in front of the sun at a supersonic speed, creating shockwaves that are caught photographically for research. NASA is using a modern version of schlieren imagery to visualize supersonic flow phenomena with full-scale aircraft in flight. The results will help engineers design a quiet supersonic transport.
It's difficult to get a sense of scale when viewing Saturn's rings, but the Cassini Division (seen here between the bright B ring and dimmer A ring) is almost as wide as the planet Mercury.
