Massive Boulders Ejected During DART Mission Complicate Future Asteroid Deflection Efforts
College Park MD (SPX) Jul 11, 2025 University of Maryland astronomers discovered that an unexpected blast of space rocks ejected during DART mission carried three times more momentum than the spacecraft itself, leading to new insights for future planetary defense missions. When NASA's DART spacecraft slammed into the asteroid moon Dimorphos in September 2022, it didn't just change the asteroid's orbit as intended-it unleashed a massive barrage of boulders that carried more than three times the momentum of the spacecraft itself. ... read more |

Numerical models uncover how barred olivine crystals formed in ancient meteorites
Tokyo, Japan (SPX) May 26, 2025 Researchers from Nagoya City University and Tohoku University have successfully simulated the formation of barred olivine, a rare mineral texture found in chondrules-small spherical particles within meteorites dating back to the early solar system. Unlike textures in Earth rocks, barred olivine is unique to these primordial materials. Led by Associate Professor Hitoshi Miura, the team used a phase-field model to numerically reproduce barred olivine structures, offering new insight into how these t ... read more
