Latest Spacecraft propulsion Stories
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.
NASA Chief Technologist Mason Peck will visit L'Garde Inc., in Tustin, Calif., on Thursday, March 15, at 9 a.m. PDT. Peck's visit will highlight ways government can partner with small business to help create the jobs of the future through investment in science and technology.
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).
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 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.
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...
