Space X made history two months ago by launching the world's most powerful rocket to Mars.
   Falcon Heavy，the 230 ft rocket，successfully launched from Cape Canaveral-the same station where NASA sent man to the moon almost 50 years ago.
   There were no humans on the Falcon Heavy-but it's not without a passenger.Founder of SpaceX.Elon Musk，sent one of his Tesla Car along for the ride with a human shape model called "Starman" sitting on the driver's seat.
   For now，the world is very excited by the successful launch of the rocket.Elon musk suggested the space trip could just become the greatest firework show ever seen.If it went wrong，the rocket actually managed to lift off.
   Why is there all this excitement？
   Watching live streams of an electric car floating in spare，while the extra engines that carried it there softly land themselves back on Earth.It's hard not to feel that we're living in the future.
   Where is all this leading？
   Falcon Heavy is a great piece of work，by the researchers at SpaceX.It's not the most powerful rocket ever made，and NASA's Space Launch System will beat it when it finally launches.But it runs very cheaply，for a rocket；the fact that it can be re-used，at relatively little expense，could launch an exciting future of much more regular space launches.
   The set of Mr.Musk's own car in the rocket is a sign of the real reason This launch is such a big deal：it is being done by a man with talent，and the strong wish to make people talk about him and what he's doing.There's no reason for the car to be going to space except for a talking point-indeed，the rocket could carry some important scientific instruments instead-but when viewed as a show for a private space company which hopes to be the future of personal space travel，everything becomes more reasonable.The idea behind that plan is that it makes such space trip much cheaper，since private companies can develop and build the rockets.The companies can then increase the money they may earn with other private satellite launches and other work，cutting down the cost of space travel.
