A sub-scale solid rocket motor designed to mimic NASA's Space Launch System, or SLS, booster design successfully was tested today by engineers at NASA's Marshall Space Flight Center in Huntsville, Ala. The 20-second firing tested new insulation materials on the 24-inch-diameter, 109-inch-long motor. The motor is a scaled down, low-cost replica of the solid rocket motors that will boost SLS off the launch pad. Marshall is leading the design and development of the SLS on behalf of the...

WALLOPS ISLAND, Va., March 14, 2012 /PRNewswire-USNewswire/ -- NASA has scrubbed the launch tonight of the five suborbital sounding rockets from the Wallops Facility in Virginia as part of a study of the upper level jet stream. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The launch was scrubbed because of an internal radio frequency interference issue with one of the rockets. The next launch attempt is no earlier than the night of Friday, March 16. The Anomalous...

MESSENGER successfully completed an orbit-correction maneuver on March 2 to lower its periapsis altitude - the lowest point of MESSENGER's orbit about Mercury relative to the planet's surface - from 405 to 200 kilometers (251 to 124 miles). This is the first of three planned maneuvers designed to modify the spacecraft's orbit around Mercury as science operations transition from MESSENGER's primary orbital mission to its extended mission. MESSENGER's orbit around Mercury is highly...

NASA's Marshall Space Flight Center in Huntsville, Ala., has issued a NASA Research Announcement for the Space Launch System (SLS) Advanced Booster risk-reduction effort. NASA is looking for an advanced booster concept with the goal of reducing risk in the areas of affordability, reliability and performance. Proposals will identify and mitigate liquid or solid booster technical risks and provide related hardware demonstrations, as well as identify high-risk areas associated with adaptation...

NASA is seeking proposals for small technology payloads that could fly on future NASA-sponsored suborbital flights. These future flights will travel to the edge of space and back, testing the innovative new technologies before they're sent to work in the harsh environment of space. "NASA's Game Changing Development Program focuses on maturing advanced space technologies that may lead to entirely new approaches for the agency's future space missions while providing solutions to significant...

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...
