The Space Launch System, the latest NASA rocket, reached what’s called KDP-C, or Key Decision Point-C. This means that the powers that be gave it the green light, which is a step farther than Ares or Heavy Lift Launch Vehicle or any of the rocket programs of the last 20 years have made. Components such as the core stage and the five-segment rocket booster have passed their critical design reviews, and Michoud has been producing barrel segments for the core stage.
So what’s next? ATK is getting ready for the first qualification motor test of the five-segment rocket booster. Sixteen R-25 engines are at Stennis, with one being readied for testing this fall. Orion’s first flight, Exploration Flight Test-1 is set to fly in December.
Onward and upward.
