PROMONTORY, Utah – Orbital ATK is test firing NASA’s Space Launch System rocket in Promontory, Utah, Tuesday.
The company said this is the largest solid rocket motor in the world that it hopes will eventually take us to deep space destinations such as Mars, and it was built right here in Utah.
This is the second two-minute, full-duration qualification test for the booster, and will provide NASA with critical data to support booster qualification for flight.
It also will be the last time the booster is fired in a test environment before the first flight of SLS and Orion in 2018.
