Dusty samples from the "most dangerous known rock in the Solar System" have been brought to Earth.

The American space agency Nasa landed the materials in a capsule that came down in the West Desert of Utah state.

The samples had been scooped up from the surface of asteroid Bennu in 2020 by the Osiris-Rex spacecraft.

Nasa wants to learn more about the mountainous object, not least because it has an outside chance of hitting our planet in the next 300 years.

But more than this, the samples are likely to provide fresh insights into the formation of the Solar System 4.6 billion years ago and possibly even how life got started on our world.

 

There was jubilation when the Osiris-Rex team caught sight of their capsule on long-range cameras.

Touchdown on desert land belonging to the Department of Defense was confirmed at 10:52 local time (14:52 GMT), three minutes ahead of schedule.

The car-tyre-sized container had come screaming into the atmosphere over the western US at more than 12km/s (27,000mph). A heatshield and parachutes slowed its descent and dropped it gently, perfectly on to restricted ground.

"This little capsule understood the assignment," said Tim Priser, the chief engineer at aerospace manufacturer Lockheed Martin. "It touched down like a feather."
