• Artist concept of NASA’s Space Launch System (SLS) 70-metric-ton configuration launching to space. SLS will be the most powerful rocket ever built for deep space missions, including to an asteroid and ultimately to Mars. The first SLS mission — Exploration Mission 1 — will launch an uncrewed Orion spacecraft to a stable orbit beyond the moon and bring it back

  • NASA has completed a complex series of tests on one of the largest composite cryogenic fuel tanks ever manufactured, bringing the aerospace industry much closer to designing, building, and flying lightweight, composite tanks on rockets. At NASA’s Marshall Space Flight Center in Huntsville, Alabama, the tank was lowered into a structural test stand where it was tested with cryogenic hydrogen

  • On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT. NASA’s Solar Dynamics Observatory captured images of the flare, which erupted on the left side of the sun. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however —

  • NASA’s Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken on Aug. 20, 1989, at a range of 4.4 million

  • Inside the Operations and Checkout Building high bay at NASA’s Kennedy Space Center in Florida, technicians dressed in clean-room suits have installed a back shell tile panel onto the Orion crew module and are checking the fit next to the middle back shell tile panel. Preparations are underway for Exploration Flight Test-1, or EFT-1. Orion is the exploration spacecraft designed

  • The destructive results of a mighty supernova explosion reveal themselves in a delicate blend of infrared and X-ray light, as seen in this image from NASA’s Spitzer Space Telescope and Chandra X-Ray Observatory, and the European Space Agency’s XMM-Newton. The bubbly cloud is an irregular shock wave, generated by a supernova that would have been witnessed on Earth 3,700 years

  • Located in the Brabazon Range of southeastern Alaska, Yakutat Glacier is one of the fastest retreating glaciers in the world. It is the primary outlet for the 810-square kilometer (310-square mile) Yakutat ice field, which drains into Harlequin Lake and, ultimately, the Gulf of Alaska. The Operational Land Imager on the Landsat 8 satellite captured this image of the glacier

  • On Aug. 19, National Aviation Day, a lot of people are reflecting on how far aviation has come in the last century. Could this be the future – a plane with many electric motors that can hover like a helicopter and fly like a plane, and that could revolutionize air travel? Engineers at NASA’s Langley Research Center in Hampton, Va.,

  • The pale rocks in the foreground of this fisheye image from NASA’s Curiosity Mars rover include the “Bonanza King” target under consideration to become the fourth rock drilled by the Mars Science Laboratory mission.  No previous mission has collected sample material from the interior of rocks on Mars. Curiosity delivers the drilled rock powder into analytical laboratory instruments inside the

  • ISS040-E-090540 (9 Aug. 2014) — One of the Expedition 40 crew members aboard the International Space Station photographed this nighttime image showing city lights in at least half a dozen southern states from some 225 miles above the home planet. Lights from areas in the Gulf Coast states of Texas, Louisiana, Mississippi and Alabama, as well as some of the

  • New data from NASA’s Chandra X-ray Observatory has provided stringent constraints on the environment around one of the closest supernovas discovered in decades. The Chandra results provide insight into possible cause of the explosion, as described in our press release.   On January 21, 2014, astronomers witnessed a supernova soon after it exploded in the Messier 82, or M82, galaxy. Telescopes across the globe and in space turned their attention

  • The center section of the “pathfinder” (test) backplane of NASA’s James Webb Space Telescope arrived at the Goddard Space Flight Center in July 2014, to be part of a simulation of putting together vital parts of the telescope. In this photograph, the backplane is hoisted into place in the assembly stand in NASA Goddard’s giant cleanroom, where over the next

  • ISS040-E-088856 (5 Aug. 2014) — NASA astronaut Reid Wiseman, Expedition 40 flight engineer, installs Capillary Channel Flow (CCF) experiment hardware in the Microgravity Science Glovebox (MSG) located in the Destiny laboratory of the International Space Station. CCF is a versatile experiment for studying a critical variety of inertial-capillary dominated flows key to spacecraft systems that cannot be studied on the

  • Divers retrieve the test vehicle for NASA’s Low-Density Supersonic Decelerator off the coast of the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii. On June 28, 2014, the vehicle was lifted to near-space with the help of a balloon and rocket in order to test new Mars landing technologies. The divers, from the U.S. Navy’s Explosive Ordnance Disposal team,
