Patrick Hull, left, and Brent Gaddes, right, receive special commendation awards for their work on critical flight hardware for the Orion spacecraft’s first mission later this fall. John Casper, center, Orion special assistant for program integration and a former astronaut, presented the awards at an Orion flight hardware celebration at the Marshall Center.Image credit: [...]
A 5-percent scale model of the Space Launch System (SLS) is ignited for five seconds to measure the effects acoustic noise and pressure have on the vehicle at liftoff. The green flame is a result of the ignition fluid that is burned along with the propellant during this short-duration test.Image/Caption Credit: NASA/MSFC/David Olive
Dr. Daniel M. Schumacher, manager of the Science and Technology Office at NASA’s Marshall Space Flight Center in Huntsville, Ala., has been honored with an award for exceptional technical achievement by the Air, Space, and Missile Defense Association, or ASMDA. The 2013 Space and Missile Service Excellence Award-Government, presented to Schumacher Jan. 7, recognizes [...]
The Morpheus Lander successfully completed its first of two successful free flight tests within a week, on Dec. 10. Image Credit: NASA/Johnson Space Center
In what looked like scenes from a retro science fiction movie, NASA’s Morpheus Lander successfully conducted its first two back-to-back free-flight tests within a week, earlier this month at the [...]

For some time now work has been under way to develop NASA’s replacement launch vehicle for the agency’s retired space shuttle fleet, the Space Launch System (SLS [...]
Using a precision formation-flying technique, the twin GRAIL spacecraft mapped the Moon’s gravity field, as depicted in this artist’s rendering. Image Credit: NASA/JPL-Caltech
Scientists, using data from the lunar-orbiting twins of NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, are gaining new insight into how the face of the Moon received its rugged good [...]
Combustion instabilities can make a rocket engine have a really bad day. High frequency combustion instabilities are periodic oscillations of combustion that occur due to the coupled interaction between unsteady heat release from combustion, acoustic fluctuations within the combustor, and perturbations of the incoming propellant.
These instabilities become [...]

Astronomers using NASA’s Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding black holes.
NASA has repeatedly tested out 3-D-printed components. The most recent of these took place on Aug. 22. Photo Credit: NASA
With several smaller, successful tests completed using the technology, NASA conducted another test firing of an engine that had a fuel injector produced by 3-D printing. The process, known as additive manufacturing, has made [...]
Just last month, Aerojet Rocketdyne tested out a rocket engine fuel injector that was produced by 3D printing. AmericaSpace spoke with Jeff Haynes, a program manager working to develop this technology for space flight purposes. He talked about the first test, what the limitations are for 3D-printed parts, as well as the ramifications for [...]
