Dr. Shantanu Naidu: “When DART made impact, things got very interesting…the entire shape of the asteroid has changed, from a relatively symmetrical object to a ‘triaxial ellipsoid’ – something more like an oblong watermelon.”

On November 24, 2021, NASA launched the Double Asteroid Redirection Test (DART) mission with the goal of demonstrating that deflecting an incoming asteroid could prevent it from striking Earth by striking the asteroid itself. Just over nine months later, on September 26, 2022, this demonstration was successfully carried out as DART acted as a kinetic impactor and intentionally struck the Dimporphos asteroid, which measures 560 feet (170 meters) in diameter.

But while the impact successfully altered Dimorphos’ orbit around the binary near-Earth asteroid, Didymos, could it have altered other aspects of Dimorphos, as well? This is what a recent study published in The Planetary Science Journal hopes to address as a team of international researchers led by the NASA Jet Propulsion Laboratory (JPL) discovered the impact also altered the shape of Dimporphos.

When it was first discovered in 2004, Apophis was identified as one of the most dangerous asteroids in that there was a risk that it could impact Earth. But that impact assessment changed over the years after astronomers tracked Apophis, also known as asteroid 99,942, and its orbit became better determined, and it became clear that it was on course to miss our planet.

The probe “performed as predicted” during the first of seven close approaches to the sun on its way to Apophis, NASA said.

Researchers measured the temperature of the Chicxulub crater 66 million years ago, unlocking mysteries of the dinosaur-dooming mass extinction event.

A newly identified species upends the theory that the dinosaurs were already dying before the asteroid.

Two tight fasteners kept the majority of the Bennu asteroid sample from scientists since it returned to Earth in September. Now they’ve finally prised it open.
