Infographic : A Brief History of Rockets

The principles of rocketry were first tested more than 2,000 years ago, but it's really only been in the past 70 years or so that these machines have been used for applications in space exploration. Today, rockets routinely take spacecraft to other planets in our solar system. Closer to Earth, rockets carrying supplies up to the International Space Station can return to Earth, land on their own and be used again.
