Jay TateThe half-a-kilometer-wide asteroid Bennu is already one of the most well-studied asteroids prior to the OSIRIS-REx mission.
By using positional data collected over the course of the two-year sample return mission, however, scientists were able to improve their knowledge of Bennu’s trajectory by a factor of 20, NASA scientists said at a press briefing.

Jay TateA close examination of the millimeter-wavelength emissions from the asteroid Psyche, which NASA intends to visit in 2026, has produced the first temperature map of the object, providing new insight into its surface properties. The findings, described in a paper published in Planetary Science Journal (PSJ) on August 5, are a step toward resolving the mystery of the origin of this unusual object,

Jay TateHow do you track an asteroid that hit the Earth over 60 million years ago? By using a combination of geology and computer simulations, at least according to a team of scientists from the Southwest Research Institute (SwRI). Those methods might have let them solve a long-standing mystery of both archeology and astronomy – where did the asteroid that killed the dinosaurs come from?

Jay TateNASA’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.

Jay TateScientists 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,

Jay TateA 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,

Jay TateAn 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.

Jay TateA 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,
…
Jay TateAn 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,

Jay TateThe 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,
