For the first time in history, a rocket that has been used before will be reused in launch.
SpaceX has launched several rockets that landed back on earth after completing the launch.
One of those rockets will be reused today to make another launch.
This is a game-changer for the space-travel industry. If successful, it will make it possible to think of space-travel like any other travel where the vehicle is reused again and again.
Eventually, Elon Musk would like to use this technology to send people to Mars, bring the rocket back, and launch again to send more people to Mars.
