Latest Spacecraft propulsion Stories
Testing has begun on an engine that could make it possible for a plane to travel into space, travel at five times the speed of sound, and make it possible to reach any destination on the planet in no more than four hours.
The next-generation engine that will help carry humans deeper into space than ever is back, bigger and better.
An experimental hypersonic glider was forced to abort its 13,000 mph flight over the Pacific Ocean during the summer of 2011 because larger than expected portions of its skin peeled off.

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...
