Falcon 9 Rocket 

                              29/9/2012, SpaceX completed a successful static fire test of the Falcon 9 rocket’s nine Merlin engines. During this test, SpaceX engineers ran through all countdown processes as if it were launch day. All nine engines fired at full power for two seconds while the rocket was held down to the pad. This is the last major all systems test in preparation for Falcon 9 and Dragon’s next mission to the space station, targeted for October 7.
