NASA solar sail asteroid mission readies for launch on Artemis I

NASA’s Near-Earth Asteroid Scout is tucked away safely inside the agency’s powerful Space Launch System (SLS) rocket at NASA’s Kennedy Space Center in Florida. The solar sailing CubeSat is one of several secondary payloads hitching a ride on Artemis I, the first integrated flight of the agency’s SLS and the Orion spacecraft.

Early Earth was bombarded by series of city-sized asteroids

Scientists know that the Earth was bombarded by huge impactors in distant time, but a new analysis suggest that the number of these impacts may have been x10 higher than previously thought.

This translates into a barrage of collisions, similar in scale to that of the asteroid strike which wiped out the dinosaurs,

Comet strike may have sparked key shift in human civilization

A cluster of comet fragments believed to have hit Earth nearly 13,000 years ago may have shaped the origins of human civilisation, research suggests.

Possibly the most devastating cosmic impact since the extinction of the dinosaurs, it appears to coincide with major shifts in how human societies organised themselves,

Researchers aim to move an asteroid

An asteroid strike on Earth could be prevented by new technology launching into space this year, involving a Queen’s University Belfast scientist.

Professor Alan Fitzsimmons from the Astrophysics Research Centre at Queen’s is playing a role in two space missions that will measure how hard it is to deflect an asteroid.

Giant comet found in outer solar system by Dark Energy Survey

A giant comet from the outskirts of our Solar System has been discovered in 6 years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit,

Lunar samples record impact 4.2 billion years ago

An international team of researchers led by The Open University (OU) has provided the first sample-based evidence, which they argue reflects the age of the Serenitatis Basin – one of the oldest craters on the Moon.

The formation and ages of the lunar basins and craters, created during large collisional impact events during the first ~500 million years of the Solar System history,

Asteroid 16 Psyche might not be what scientists expected

The widely studied metallic asteroid known as 16 Psyche was long thought to be the exposed iron core of a small planet that failed to form during the earliest days of the solar system. But new University of Arizona-led research suggests that the asteroid might not be as metallic or dense as once thought,

Earth’s meteorite impacts over past 500 million years tracked

For the first time, a unique study conducted at Lund University in Sweden has tracked the meteorite flux to Earth over the past 500 million years. Contrary to current theories, researchers have determined that major collisions in the asteroid belt have not generally affected the number of impacts with Earth to any great extent.

Did heat from impacts on asteroids provide the ingredients for life on Earth?

A research group from Kobe University has demonstrated that the heat generated by the impact of a small astronomical body could enable aqueous alteration and organic solid formation to occur on the surface of an asteroid. They achieved this by first conducting high-velocity impact cratering experiments using an asteroid-like target material and measuring the post-impact heat distribution around the resulting crater.

Research sheds light on origins, age of massive impact crater

Hidden beneath a kilometre of ice in northwestern Greenland, an impact crater that could swallow a city the size of London, Ont. is the subject of much debate about its origins and age.

Now, Western planetary scientist Elizabeth Silber has published new research suggesting the crater could be young –
