NASA’s SLS Solid Rocket Boosters: What is DM-1?

Demonstration Motor-1 (DM-1) is the first full-scale ground test of the evolved five-segment solid rocket motor of NASA’s SLS (Space Launch System) rocket. The event will take place in Promontory, Utah, and will be used as an opportunity to test several upgrades made from the current solid rocket boosters. Each booster burns six tons of solid propellant every second and together generates almost eight million pounds of thrust.
