A company who make rockets to take tourists into space say they have successfully launched and landed a spacecraft in America.
The rocket is designed to take off and land standing up so it can used more than once; it's the first time that a rocket has managed to do this successfully.
The New Shepard rocket took off from West Texas in the US with no-one aboard and landed safely again.
It can carry up to six people into earth's upper atmosphere, where they will be able to experience weightlessness.
Reusing rockets, rather than discarding them, would be a big step toward making space travel less expensive.
