The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]

The DART impact on the center of Dimorphos decreased the orbital period, previously 11.92 hours, by 33±1 minutes. This large change indicates the recoil from material excavated from the asteroid and ejected into space by the impact (known as ejecta) contributed significant momentum change to the asteroid, beyond that of the DART spacecraft itself.
Earth is getting a temporary second "mini moon," a.k.a. the 2024 PT5 asteroid. Here's how you can see it and if it will affect your astrological star sign.
NASA’s Dart mission ship successfully slammed into the tiny asteroid Dimorphos at 7:14 p.m. Monday, the space agency announced.
In horoscopic astrology, a Saturn return is an astrological transit that occurs when the planet Saturn returns to the same ecliptic longitude that it occupied at the moment of a person's birth. [ 1 ] [ 2 ] While the planet may not first reach the exact location until the person is 29 or 30 years old, the influence of the Saturn return is ...
The NASA Double Asteroid Redirection Test (DART) kinetic impactor spacecraft was launched in November 2021. The goal was to impact Dimorphos (nicknamed Didymoon), the 180-meter (590 ft) minor-planet moon of near-Earth asteroid 65803 Didymos. The impact occurred in September 2022 when Didymos is relatively close to Earth, allowing Earth-based ...
Ever since we learned that an asteroid sucker punched the dinosaurs 66 million years ago, we’ve been a little bit worried it might happen again, but with us in the crosshairs.
