NASA Goddard Space Flight Center has developed technology that uses inductive power transfer (IPT) for wireless power interfaces between spaceflight elements (such as the payload, vehicle, and pad). Current spaceflight systems require traditional hardwire connections for power interfaces. This...
On September 1, 1961, NASA requested appropriations for initial land purchases on Merritt Island on Florida’s east coast to support the Apollo Lunar Landing Program. Designers quickly began developing...
For the first time in a generation, NASA is building a human spacecraft for deep-space missions that will usher in a new era of space...
On July 20, 1969, humans walked on another world for the first time in history. After a landing that included dodging a lunar crater and boulder...
Employing fluid power to achieve mechanical motion can be implemented via hydraulics using uncompressible liquids or via pneumatics using compressible gasses; typically, air. The latter provides several...
This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...
Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...
Electromagnetic motors typically convert electrical energy into rotational mechanical energy and are employed across a wide array of applications. While motors represent relatively mature technology, practitioners continue to seek ways to enhance motor operation including a decrease in cost, drop in size/weight,...
Founded on July 1, 1960, Marshall Space Flight Center in Huntsville, AL is one of NASA’s largest field centers. Marshall engineers designed, built, tested, and helped launch the Saturn V...
Rocket engine testing requires a lot of light since all tests are filmed with high-speed cameras to monitor performance; however, those cameras have to adjust to the bright plume from a firing...
Mechanical systems such as engines and motors rely on two principal types of motions of stiff components: linear motion, which involves an object moving from one point to another in a straight...
Making electric cars lighter also involves reducing the weight of the motor. One way to do that is by constructing it from fiber-reinforced polymer materials. A new cooling concept...
Recent technical advances have enabled flywheel energy storage systems (FESS) to become more compact and able to support higher-power applications. Due to their proven...
Spinoff is NASA’s annual publication featuring successfully commercialized NASA technology. This commercialization has contributed to the development of products and services in...
An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot — particulate matter consisting...
NASA Johnson Space Center developed reprogrammable and interchangeable electronic controllers that can attach to a system or subsystem wirelessly or through plug-and-play capability. Originally designed to work with rocket engines, this technology can control...
NASA required a rocket thruster able to produce a number of pulses at high specific impulse at a relatively low voltage (~300 to 400V). The key problem was that existing propellants for liquid-fueled pulsed plasma thrusters (LPPTs) required high voltages to ablate and accelerate...
WCX™ World Congress Experience 2019 — presented by SAE International — is for forward-thinking engineers, executives, OEMs, suppliers, decision-makers, disruptors, and the entire spectrum of...
Soft landing using rockets requires a trajectory to be planned for the lander from rocket ignition — typically several kilometers in altitude and moving at up to 200 m/s — to the point near the surface with near-zero velocity. The exact...
