Dust grains older than our sun found in Asteroid Ryugu samples
Aug 18, 2022 (SPX)
Named after a Japanese folktale, Ryugu is a near-Earth object shaped kind of like a spinning top that orbits the Sun every 16 months. Hayabusa2 was the first mi...
NASA's Lucy team discovers moon around asteroid Polymele
Aug 18, 2022 (SPX)
On March 27, Lucy's science team discovered that the smallest of the mission's Trojan asteroid targets, Polymele, has a satellite of its own. On that day, Polym...
Space mission shows Earth's water may be from asteroids
Aug 16, 2022 (AFP)
In a quest to shed light on the origins of life and the formation of the universe, researchers are scrutinising material brought back to earth in 2020 from the ...
Meteorite provides record of asteroids spitting out pebbles
Aug 12, 2022 (SPX)
"It's fascinating to see something that was just discovered by a space mission on an asteroid millions of miles away from Earth, and find a record from the same...
Study finds evidence that giant meteorite impacts created the continents
Aug 11, 2022 (SPX)
Dr Tim Johnson, from Curtin's School of Earth and Planetary Sciences, said the idea that the continents originally formed at sites of giant meteorite impacts ha...
What part of a space rock survives to the ground?
Aug 09, 2022 (SPX)
"Most of our meteorites fall from rocks the size of grapefruits to small cars," says lead author and meteor astronomer Peter Jenniskens of the SETI Institute an...
NASA team troubleshoots asteroid-bound Lucy across the solar system
Aug 04, 2022 (SPX)
Data indicated that one of Lucy's solar arrays powering the spacecraft's systems - designed to unfurl like a hand fan - hadn't fully opened and latched, and the...
Modeling reveals how dwarf planet Ceres powers unexpected geologic activity
Aug 02, 2022 (SPX)
Then, in 2015, the hazy orb that was Ceres came into view. That view was stunning to scientists such as King. Data and images collected by NASA's Dawn mission g...

Jul 26, 2022 (SPX)
We are committed to launch the first asteroid mining mission in 2027 targeting 1,000 kg of platinum worth around $34 million. However, the Recovery Capsule retu...
Some asteroids aged early by Sun
Jul 25, 2022 (SPX)
Tens of thousands of years might sound pretty slow, but "we thought surface regeneration on asteroids took a few millions of years," said Marco Delbo, senior sc...
DLR to investigate dust from asteroid Ryugu
Jul 20, 2022 (SPX)
"Hayabusa2 was and is one of the most complex missions in the history of research into the bodies of the Solar System," emphasises Anke Pagels-Kerp, DLR Divisio...
Hopping space dust may influence the way asteroids look and move
Jul 13, 2022 (SPX)
That popcorn-like effect may even help to tidy up smaller asteroids, causing them to lose dust and look rough and craggy from space. The researchers published t...
Asteroid Bennu Reveals its Surface is Like a Plastic Ball Pit
Jul 11, 2022 (SPX)
It turns out that the particles making up Bennu's exterior are so loosely packed and lightly bound to each other that if a person were to step onto Bennu they w...
SwRI-led study provides new insights about surface, structure of asteroid Bennu
Jul 08, 2022 (SPX)
"The low gravity of rubble-pile asteroids such as Bennu weakens its near-subsurface by not compressing the upper layers, minimizing the influence of particle co...
