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...

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...

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...
