The booster for the world’s most powerful rocket, NASA’s Space Launch System (SLS), which will power the agency’s astronauts on the journey to Mars, will fire up for a major ground test at 10:05 a.m. EDT (8:05 a.m. MDT) Tuesday, June 28, at Orbital ATK Propulsion Systems’ test facilities in Promontory, Utah.
This is the last time the booster will be fired in a test environment before the first test flight of SLS with NASA’s Orion spacecraft, known as Exploration Mission-1 (EM-1), in late 2018.
NASA Television will air a NASA Social event that provides the latest updates and background on SLS and Exploration Mission-1 at 3:30 p.m. Monday, June 27, and will air live coverage of the booster test June 28 beginning at 9:30 a.m.
Following the test, NASA will hold a media teleconference at 11 a.m. to discuss initial assessment of the booster firing. The teleconference participants will be:
Bill Gerstenmaier, associate administrator for Human Exploration and Operations at NASA Headquarters in Washington
Charlie Precourt, vice president and general manager of Orbital ATK’s Propulsion Systems Division in Promontory, Utah
Alex Priskos, manager of the NASA SLS Boosters Office at Marshall Space Flight Center in Huntsville, Alabama
