CANOGA PARK, Calif., April 24, 2013 /PRNewswire/ -- Pratt & Whitney Rocketdyne, the rocket-engine manufacturer that helped power American astronauts to the moon during the Apollo era, has completed the last in a series of hot-fire tests on a J-2X engine with a stub-nozzle extension at simulated altitude conditions. This latest chapter in the development of America's next rocket engine paves the way toward full-motion testing of the J-2X engine, which is designed to power humans to Mars....

Michael Harper for redOrbit.com — Your Universe Online There are many who would like to one day go to Mars. This list of willing candidates likely dries up when asked to dedicate a total of four years to the trip. The Inspiration Mars Foundation, on the other hand, believes they can shoot a couple around the Red Planet and back again in just over 500 days. Now, researchers at the University of Washington aim to make the trip in even less time — somewhere around 30 days, to...

CENTENNIAL, Colo., April 5, 2013 /PRNewswire/ -- United Launch Alliance recently honored three California-based suppliers with a 2012 Small Business Excellence award for their support of the Atlas V and Delta IV launch vehicles. ULA's Atlas and Delta vehicles support a wide range of missions including the Department of Defense Evolved Expendable Launch Vehicle (EELV) Program and NASA science missions, and are poised to launch the next generation of astronauts to the International...

Researchers Developing Elecrohydrodynamic Thrust Technology
2013-04-03 19:12:11

Lee Rannals for redOrbit.com — Your Universe Online MIT researchers writing in the journal Proceedings of the Royal Society A say they found ionic wind thrusters may be a more efficient source of propulsion than conventional jet engines. Ionic wind, or electrohydrodynamic thrust, was first identified in the 1960s. The phenomenon takes place when a current passes between two electrodes, creating a wind in the air between. If enough voltage is applied, the wind produces a thrust...

Electric rocket engines known as Hall thrusters, which use a super high-velocity stream of ions to propel a spacecraft in space, have been used successfully onboard many missions for half a century. Erosion of the discharge channels walls, however, has limited their application to the inner solar system. A research team at Caltech's Jet Propulsion Laboratory, in Pasadena, Calif., has found a way to effectively control this erosion by shaping the engine's magnetic field in a way that shields...

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...
