Elon Musk's SpaceX launched a successful test flight on Sunday, the last major simulation before it plans to dispatch a crew to the International Space Station (ISS).
The test simulated an emergency ejection of astronauts minutes after launch.
SpaceX CEO Elon Musk said after the test that he expects the first crewed mission could happen before June 2020.
No one was on board the rocket that launched from the Kennedy Space Center in Florida.
The private company is under contract with the US' National Aeronautics and Space Administration (NASA).
SpaceX put a new Crew Dragon capsule on top of a Falcon 9 rocket programmed to lift off into space.
As planned, the capsule's parachutes were deployed and it splashed into the Atlantic Ocean minutes after liftoff.
NASA's administrator Jim Bridenstine tweeted his congratulations for the team and said that recovery operations were underway.
