Asteroid Stories
These X-ray computed tomography (XCT) scans released on March 17, 2026, give us a glimpse inside asteroid Bennu. They show the most common types of crack networks observed in Bennu samples; these networks solved a mystery that baffled NASA for…
In one of the biggest surprises of NASA's OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches of sandy or pebbly material scientists had expected…
Editor’s Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. These results were reported as part of NASA’s role in the International Asteroid Warning Network. NASA’s James Webb Space Telescope…
New research reveals that when NASA’s DART (Double Asteroid Redirection Test) spacecraft intentionally impacted the asteroid moonlet Dimorphos in September 2022, it didn’t just change the motion of Dimorphos around its larger companion, Didymos; the crash also shifted the orbit…
The asteroid Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth by NASA’s OSIRIS-REx…
Lucy’s high-resolution, black-and-white imager, L’LORRI, captured a series of photos between Sept. 15–17, as the comet was zooming toward Mars. Lucy was 240 million miles away from 3I/ATLAS, well beyond the orbit of Mars, on its way to explore eight…
At 12:56 p.m. EDT on Tuesday, Sept. 23, NASA’s OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification, and Security – Apophis Explorer) spacecraft will fly within about 2,100 miles (3,400 kilometers) of Earth. Passing about 100 times closer to Earth than the…
The IAU (International Astronomical Union), a global naming authority for celestial objects, has approved official names for features on Donaldjohanson, an asteroid NASA’s Lucy spacecraft visited on April 20.
On Sept. 11, 2022, engineers at a flight control center in Turin, Italy, sent a radio signal into deep space. Its destination was NASA’s DART (Double Asteroid Redirection Test) spacecraft, which was flying toward an asteroid more than 5 million…
The dwarf planet is cold now, but new research paints a picture of Ceres hosting a deep, long-lived energy source that may have maintained habitable conditions in the past. New NASA research has found that Ceres may have had a…
