"DART Mission: NASA Alters Asteroid's Shape and Orbit"

NASA's DART spacecraft successfully changed the trajectory and shape of the Dimorphos asteroid, demonstrating the potential to avert a disastrous impact on Earth. The intentional collision altered the asteroid's shape from a symmetrical oblate spheroid to an oblong watermelon due to its loosely packed debris composition. The collision reduced Dimorphos' orbit time around its parent asteroid, Didymos, and upcoming ESA's Hera spacecraft will provide further insights into the asteroid's changed shape and orbit.

DART Mission Unleashes Swarm of Boulders in Asteroid Collision

NASA's Hubble Space Telescope has observed a swarm of 37 boulders that were ejected from the asteroid Dimorphos after the DART spacecraft crashed into it as part of a planetary defense test mission. The impact successfully changed Dimorphos' orbit, bringing it closer to its parent asteroid. The boulders, ranging in size from three to 22 feet, likely flew off the surface of Dimorphos due to the collision. Astronomers hope to gather more data to understand the precise trajectories of the boulders and analyze the impact further with the upcoming Hera probe mission in 2024.

ESA's Hera mission set to launch gravimeter to Dimorphos asteroid.

The European Space Agency's Hera mission, which will complete the first post-impact survey of the asteroid that NASA's Double Asteroid Redirection Test collided with in September 2022, is closer to launch after the gravimeter for small solar system objects (GRASS) completed its ground tests. GRASS is a tiny instrument that can measure the gravity levels of an asteroid and will be carried by Hera to measure the minuscule gravity levels of Dimorphos, the orbiting moonlet of the 65803 Didymos binary system. GRASS is designed to measure the expected gravity levels and the precise mass of the Dimorphos asteroid.
