RS-25 Engines: Meeting the Need for Speed
Houston TX (SPX) Aug 18, 2015
Rocket engines are among the most amazing machines ever invented. That's mainly because they have to do one of the most extreme jobs ever conceived - spaceflight - starting with escaping Earth's deep gravity well. Orbital velocity, just for starters, is over 17,000 mph, and that only gets you a couple hundred miles off the surface. Going farther requires going faster. Much faster. The RS-25 makes a modern race car or jet engine look like a wind-up toy. It has to handle temperatures as low as minus ... read more
