SpaceX Launches World's Most Powerful Rocket
SpaceX, a private space transport company owned by American billionaire Elon Musk, has launched the world's most powerful rocket, the Falcon Heavy. It is the larger version of the Falcon 9 rocket, which has successfully been putting payloads into space for years. The booster is made up of three rockets strapped together for combined thrust.
The Falcon Heavy was developed over a period of 7 years and cost about $500 million. It is 23 stories tall and has 27 engines. The rocket's thrust equals that of 18 Boeing 747 jumbo jets.
The new rocket is designed to send large satellites into earth orbit. It can carry 64 metric tons, twice the payload of other rockets, into space at a lower price. The rocket can also transport spacecraft to destinations further away from earth. In addition, its starting boosters are reusable.
SpaceX has been flying NASA cargo missions to the International Space Station for a few years. The company wants to compete with other business in carrying payloads to space. Musk's company has several commercial customers and has been receiving contracts to fly government payloads. The first manned mission to space is planned for the end of 2018.
