Booster for our SLS Rocket 'Chills Out' Ahead of Super-Hot Ground Test: Seen here, a technician inspects hardware and instrumentation on a full-scale, test version booster for NASA's new rocket, the Space Launch System. The booster is being cooled to approximately 40 degrees Fahrenheit ahead of its second qualification ground test June 28 at Orbital ATK's test facilities in Promontory, Utah.

It will take more than a month to reach the booster's cold temperature target of 40 degrees Fahrenheit inside the test facility. Sensors inside and outside the booster measure the propellant temperature, and analytical models also predict the time it takes for the booster to be chilled. Testing at the thermal extremes experienced by the booster on the launch pad is important to understanding the effects of temperature on the performance of how the propellant burns.
