Fired up! Did you miss today's booster test for our Space Launch System, the world’s most powerful rocket? Watch it now! During the SLS flight the boosters will provide more than 75 percent of the thrust needed to escape the gravitational pull of the Earth, the first step on our journey to Mars.

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.
