The world’s most efficient rocket engine came to life again today, unleashing 512,000 pounds of thrust and a thunderous roar across southern Mississippi and NASA’s Stennis Space Center during a 535-second full power test fire. The same engine that powered the space shuttle so reliably for years, the RS-25, will again be employed […]
