The Falcon 9 rocket engine test
Nine Merlin engines power the first stage of the Falcon 9, each one delivering 125,000 pounds of thrust, which will send its Dragon payload spacecraft into orbit with a capacity for 20 tons of cargo. The Dragon module is capable of reaching the ISS, and once the cargo phase is thoroughly tested it will be qualified for human spaceflight.
