America's newest capsule for astronauts has blasted off towards the International Space Station on a test flight.
It's been designed by the firm SpaceX.
It successfully launched from the Kennedy Space Center in Florida in the early hours of this morning.
For this 'Demo-1' mission the capsule is unmanned, instead containing a life-size test dummy.
However, NASA and SpaceX are hoping the craft could regularly carry humans to and from the International Space Station (ISS).
The test involves a Falcon 9 rocket and Crew Dragon spacecraft.
NASA Administrator Jim Bridenstine said today's launch "represents is a new era in spaceflight".
He said: "We’re looking forward to being one of many customers in a robust commercial marketplace in low-Earth orbit.”
SpaceX CEO Elon Musk, meanwhile, explained that the launch went as expected and "everything is nominal".

SpaceX NASA partnership
NASA and SpaceX have teamed up as part of the space agency's 'commercial crew programme'.
If this test is successful, a planned Demo-2 mission will carry two NASA astronauts - Bob Behnken and Doug Hurley - to the ISS.
NASA is currently hoping that mission will take place in July.
Meanwhile, the newly-launched Crew Dragon is set to dock with the ISS tomorrow.
It will remain there until next Friday.
The spacecraft's then expected to return to Earth and 'splash down' in the Atlantic Ocean several hours later.
NASA said the current test is a "significant step toward returning to the nation the capability to launch astronauts on a US-built spacecraft from US soil".
Such flights haven't taken place since the retirement of the space shuttle programme in 2011.
