2011-11-18 11:52:49

The US Army conducted its first flight test of its new Advanced Hypersonic Weapon (AHW), launching the high-tech bomb from the Pacific Missile Range Facility in Kauai on Thursday. After launch, the rocket glided through the upper atmosphere over the Pacific “at hypersonic speed” before reaching its target on the Kwajalein atoll in the Marshall Islands, according to a statement made by the Pentagon. The rocket made the trip from Kauai to Kwajalein -- some 2,500 miles...

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...
