Scientists have analyzed images of the twin asteroids Didymos and Dimorphous taken by NASA's DART mission before it impacted the smaller space rock...

Asteroid Bennu's boulder-covered surface gives it protection against small meteoroid impacts, according to observations of craters by NASA's OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) spacecraft. OSIRIS-REx traveled to near-Earth asteroid Bennu

Scientists analyzing data from the DART mission in 2022 have found new evidence of how the binary asteroid system of Didymos and Dimorphos originated. The post When the DART mission struck an asteroid moon first appeared on EarthSky.

In the moments before NASA's DART spacecraft slammed into the asteroid Dimorphos in a landmark planetary defense test in 2022, it took high-resolution images...

In studying data collected from NASA's DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission's science team has discovered new information on the origins of the target binary asteroid system and why the DART spacecraft was so effective in shifting Dimorphos' orbit.

Since NASA's Double Asteroid Redirection Test (DART) successfully impacted its target nearly five months ago, on September 26 — altering the orbit of the asteroid moonlet Dimorphos by 33 minutes — the DART team has been hard at work analyzing the data collected from the world's first planetary defen
