Some things, like gum and diapers, are designed to only be used once.
According to SpaceX though, their Falcon 9 rocket is not one of those things.
For the first time ever, SpaceX has launched and landed a rocket that had flown to space before.
This historic milestone was described as a "huge revolution in spaceflight" by SpaceX CEO Elon Musk following the mission.
This rocket was previously flown in April of last year.
SpaceX started working 6 years ago to try to make their rockets reusable, something Musk has envisioned for a decade and a half.
