The Europe Space Agency (ESA) has successfully completed its first test flight of a new space plane.
The flight lasted about an hour and a half and a massive rocket helped to blast the two tonne craft into space.
The space plane successfully landed in the Pacific Ocean, and the director-general of the ESA said that the test "couldn't have gone better."
Scientists launched the craft to learn how to overcome the problems they face when trying to come back to Earth.
When spacecrafts re-enter the Earth's atmosphere, the air slows down the space ship causing friction.
This friction then causes the craft to heat up, and could be quite dangerous for the mini-plane.
On its return to Earth the surface of the mini-space shuttle reached temperatures of 1,700 degrees Celsius.
The ESA hope that this test will help improve how space shuttles re-enter the Earth's atmosphere allowing them to be re-used more than once.
