NASA'S Space Technology Program has selected 14 technologies for development and demonstration on commercial reusable suborbital launch vehicles. The selected proposals offer innovative cutting-edge ideas and approaches for technology in areas including active thermal management, advanced avionics, pinpoint landing and advanced in-space propulsion. They also address many of the high-priority technology needs identified in the recent National Research Council's Space Technology Roadmaps and...

NASA Surpasses Test Facility Record With J-2X Powerpack Test
2012-06-10 04:53:41

NASA's Stennis Space Center near Bay St. Louis, Miss., broke its own record Friday when it conducted a test on the new J-2X powerpack. The test lasted for 1,150 seconds, surpassing the previous record by more than a full minute. For NASA, the test marked a milestone step in development of a next-generation rocket engine to carry humans deeper into space than ever before. For Stennis, the 19-minute, 10-second test represented the longest duration firing ever conducted in the center's A Test...

'Critical' Spaceplane Engine Testing Underway
2012-04-29 04:30:10

Testing has begun on an engine that could make it possible for a plane to travel into space, travel at five times the speed of sound, and make it possible to reach any destination on the planet in no more than four hours, Suzannah Hills of the Daily Mail reported on Saturday. The vehicle in question is the Skylon, an unmanned, reusable spaceplane that is currently in development at UK aerospace company Reaction Engines Ltd (REL). According to Hill, the craft can take off and land from any...

The next-generation engine that will help carry humans deeper into space than ever is back, bigger and better. The J-2X engine is currently on the A-2 Test Stand at NASA's Stennis Space Center in Mississippi for an extensive round of tests to build on last year's successful test firings. The engine will provide upper-stage power for NASA's evolved Space Launch System (SLS), a new heavy-lift rocket capable of missions to deep space. "We're making steady and tangible progress on our new...

Shell Degradation Cause Of DARPA Hypersonic Vehicle Flight Abort
2012-04-22 03:57:05

An experimental hypersonic glider was forced to abort its 13,000 mph flight over the Pacific Ocean during the summer of 2011 because larger than expected portions of its skin peeled off, officials from the US Defense Advanced Research Projects Agency (DARPA) announced on Friday. According to the Associated Press (AP), the Hypersonic Technology Vehicle-2 (HTV-2) launched atop a rocket from California's Vandenberg Air Force Base last August 11 as part of research into the development of...

Escape Velocity -- An escape velocity is the minimum speed at which an object without propulsion can move away from a source of a gravitational field indefinitely if there is no friction. This definition may need modification for the practical problem of two or more sources in some cases. In any case, the object is assumed to be a point with a mass that is negligible compared with that of the source of the field, usually an excellent approximation. It is commonly described as the speed...
