"NASA tested the new first-stage solid rocket motor for the Ares I rocket. The static firing of the five-segment solid motor, designated development motor -1 was conducted at the ATK test facility in Promontory, Utah."
Once again, I am very happy with the use of large solid motors in NASA rockets. Overall, they are less expensive and often reusable.
