The third installment of this video series takes a look at the basics of the monumental energy that makes NASA’s Space Launch System (SLS) rocket go up. The initial configuration of the SLS uses two different means of powering itself during launch – solid rocket boosters and liquid-fuel engines. Host Stephen Granade explores why we have boosters and engines, the difference between the two and what role each plays during a launch. For more information on SLS, visit www.nasa.gov/sls
