"Elon Musk's aerospace company SpaceX has successfully completed a test fire of its Falcon Heavy — the world's most powerful rocket booster, which will one day carry humans to Mars. A video of the test fire at SpaceX's development facility in McGregor, Texas, shows the rocket's engines being ignited while the vehicle is strapped down. Black and white smoke pour out from beneath the rocket, giving an indication of how powerful the engines are. The Falcon Heavy is essentially a souped up version of SpaceX's Falcon 9 rocket booster, which is regularly used to carry supplies to the International Space Station. It is composed of three Falcon 9s strapped together, with a total of 27 engines generating more than 5 million pounds of thrust — equal to approximately eighteen 747 aircraft." (05/10/17)
