Get ready! The largest, most powerful rocket booster built for flight will fire up for a major ground test Tuesday at Orbital ATK's test facilities in Promontory, Utah. This is the last, full-scale qualification test for the booster before the first, uncrewed flight of our new rocket, the Space Launch System, with the Orion spacecraft in 2018.

RS-25 engines powering NASA's SLS (Space Launch System) rocket use liquid oxygen and liquid hydrogen as propellants – the same elements that combine to create water (H2O). For an RS-25 engine test, liquid hydrogen and liquid oxygen are mixed in the engine combustion chamber and ignited, which results in extremely high-temperature exhaust (up to 6,000 degrees F) exiting the nozzle into the flame deflector at a very high rate and pressure. Hundreds of thousands of gallons of water also are flowing
