Na 28 czerwca 2016 zaplanowano drugi test ogniowy boostera rakiety SLS.
A full-scale, test version of the booster for NASA's new rocket, the Space Launch System, will fire up for the second of two qualification ground tests June 28 at prime contractor Orbital ATK's test facility in Promontory, Utah. The test will provide NASA with critical data to support booster qualification for flight.
The second test will measure the booster’s performance at a cold motor conditioning target of 40 degrees Fahrenheit – which is the colder end of its accepted propellant temperature range. Testing at the thermal extremes experienced by the booster on the launch pad is important to understand the effect of the temperature range on the ballistic performance of the propellant.

“Ground tests are very important – we strongly believe in testing before flight to ensure lessons-learned occur on the ground and not during a mission,” said Charlie Precourt, Vice President and General Manager of Orbital ATK’s Propulsion Systems Division and four-time space shuttle astronaut. “With each test we have learned things that enable us to modify the configuration to best meet the needs for the upcoming first flight.”
