SpaceX Poised to Test Launch Largest Rocket Yet by VOA News The private space company SpaceX is scheduled to test launch its largest rocket yet Tuesday, and if all goes well, it will also send a sports car into orbit around the sun. WATCH: Falcon Heavy Test Flight LIVE The Falcon Heavy rocket is poised to blast off from Florida's Kennedy Space Center. SpaceX chief and high-tech entrepreneur Elon Musk tweeted an update: It is equipped with three boosters and 27 engines designed to provide more than 2 million kilograms of thrust. If successful, it will be the most powerful rocket is use today, and the most powerful used since NASA's Saturn 5 rockets last carried astronauts to the moon 45 years ago. While such test rockets usually use things like steel or concrete slabs as payload, Musk has placed a cherry red Tesla roadster electric sports car on top of the rocket. With a mannequin "Starman" sitting at the wheel, the plan is for the car to be set in an orbit around the sun. In a tweet last month, Musk said he loves the thought of a car driving - apparently endlessly through space and, perhaps being discovered by an alien race millions of years in the future.
