Have you ever imagined a car moving around our sun? It is true that a red Tesla car is moving around the sun right now. It's been in space since February 2018, when the private company SpaceX launched (发射) its first flight of the new Falcon Heavy rocket with the car as its test payload (有效荷载).
In 2002, young Elon Musk started the company because of his love and interest for space exploration (探索). After an unsuccessful try at buying Russian rockets to help him send mice to Mars and back, the young man made a surprising decision. He planned to build his own rockets.
Musk went to Southern California and started attracting people to help bring his dream to life. In a pretty short time, although with difficulties, SpaceX launched Falcon 1, the first successful privately-built rocket in 2008.
For SpaceX, the successful launch of Falcon 1 was a major achievement. But it was just the beginning of well-known firsts for the company. As the first Falcon rocket began testing, development for the Falcon 9 had been prepared. This much larger rocket, which uses nine engines, has another extremely important design. The rocket is able to return to Earth and land on their own power, ready to be reused for another flight!
This is an unbelievable development in the world of spaceflight. It can greatly reduce the cost of launching things into space. And Musk believes reusability is the key to the future of space exploration. And the effort has paid off. SpaceX has made it possible to put satellites (卫星) into space and provide needs for the International Space Station. But that's just the beginning, SpaceX has made plans for manned tasks. Perhaps someday, a SpaceX rocket with astronauts will pass by Musk's car on its way to Mars.
