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. L'Garde has received several contracts with NASA on a variety of projects, including the creation of inflatable structures for radio frequency antennas and solar arrays. In 1996, L'Garde flew the Inflatable Antenna...

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...

NASA Tests J-2X Engine
2012-01-26 06:47:36

A new series of tests on the engine that will help carry humans to deep space will begin next week at NASA´s Stennis Space Center in southern Mississippi. The tests on the J-2X engine bring NASA one step closer to the first human-rated liquid oxygen and liquid hydrogen rocket engine to be developed in 40 years. Tests will focus on the powerpack for the J-2X. This highly efficient and versatile advanced rocket engine is being designed to power the upper stage of NASA's Space Launch...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
