SpaceX has successfully launched a futuristic starship that will eventually be used to send people to Mars for the first time.
The test flight soared more than six miles above the Gulf of Mexico before flipping over to descend horizontally and back to vertical again for the successful touchdown.
A fire emerged at the base of the upgraded SpaceX rocket, but it was quickly extinguished.
Experts behind the flight will breathe a sigh of relief, after the four previous tests ended in fiery explosions before.
And there ecstatic emotions aplenty at mission control following the successful landing.
Launch commentator John Insprucker said: “Starbase Flight Control has confirmed, as you can see on the live video, we are down. The Starship has landed!”
SpaceX head Elon Musk later tweeted : “Starship landing nominal!”
Success came on the 60th anniversary of the flight of Alan Shepard, the first American in space, and it capped a stunning two weeks of achievements for SpaceX.
This has included the launch of four more astronauts to the space station for Nasa, the nation's first night-time crew splashdown since the Apollo moonshots, and a pair of launches for its mini internet satellites.
Less than a month ago, Nasa chose SpaceX's Starship to deliver astronauts to the lunar surface in the next few years.
The 3 billion dollar (£2.15 billion) contract was halted last week, however, after the losing companies - Jeff Bezos' Blue Origin and Dynetics - protested the selection.
Mr Musk said last month that the Nasa money will help development of Starship, which is meant to eventually launch atop a Super Heavy booster.
He said it has been a "pretty expensive" project so far and mostly funded internally.
"As you can tell, if you've been watching the videos, we've blown up a few of them. So excitement guaranteed, one way or another," Mr Musk told reporters after the private company's second crew flight on April 23.
