SpaceX was founded by him and he is an active force in the development low-cost, efficient spaceships. He hopes to send humans to Mars by the end of this decade and believes that it should not cost more than $200,000 per person to make a complete trip to the Red Planet.

Elon said that his reusable rocket could travel from Mars to Earth in 20 minutes. It could also carry up to 200 people.

But, everyone has been astonished by a new discovery. In 1952, Wernher von Braun wrote The Mars Project. He discussed how humans will one day reach Mars because of Elon.

He was a rocket scientist, an astronautics engineer and a space architect. While writing his book, he spent a lot of time on the one that will get us there.
