While engineers made some progress toward this goal, the paraglider wings never deployed fast enough to be effective. NASA eventually scrapped the idea in 1964. While initially disappointing, the switch to a water landing system was probably for the best. On early Gemini flights, astronauts ...
Star Wars is a U.S. government program responsible for the research and development of a space-based system to defend the nation from attack by strategic ballistic missiles. Rail guns could fire projectiles to intercept the incoming missiles. Some scientists argue that rail guns could also ...
Hypersonic speed is five times the speed of sound. Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach. Sound has a speed of Mach 1 and anything Mach 5 or above is considered hypersonic. While the speed of sound changes depending on temperature and...
Gun barrels have spiraling grooves cut into them that make bullets spin around very fast as they emerge. A spinning bullet is like a gyroscope: a sort of "stubborn" spinning wheel that always tries to keep turning the same way. If you try to tilt a gyroscope while it's spinning, it wi...

fast at launch or it won't escape from Earth, but that's a little bit misleading, for several reasons. First, it would be more correct to refer to "escape speed," since the direction of the rocket (which is what the word velocity really implies) isn't all that relevant and will ...
ballistic missiles and may be better suited to controlling escalation. Ballistic missiles, which fly high and fast, require different capabilities to intercept,” he added. “Iran is home to the largestballistic missile arsenalin the Middle East and has increasingly become a drone power ...
