Massive Boulders Ejected During DART Mission Complicate Future Asteroid Deflection Efforts
College Park MD (SPX) Jul 09, 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 |

Ancient pollen reveals stories about Earth's history, from the asteroid strike that killed the dinosaurs to the Mayan collapse
Rolla MO (SPX) May 21, 2025 If you are sneezing this spring, you are not alone. Every year, plants release billions of pollen grains into the air, specks of male reproductive material that many of us notice only when we get watery eyes and runny noses. However, pollen grains are far more than allergens - they are nature's time capsules, preserving clues about Earth's past environments for millions of years. Pollen's tough outer shell enables it to survive long after its parent plants have disappeared. When pollen grain ... read more
