• New studies suggest smaller impactors could be a better planetary defense strategy against asteroids

    Two studies published in Nature Communications explore and provide insights into efficient planetary defense strategies. These studies came out during the period when 2024 YR4 made headlines with its potential for impact in 2032. The results provide valuable insights into how to create better planetary defense procedures based on the behavior of asteroid Dimorphos ejecta produced by NASA’s Double Asteroid Redirection Test (DART) mission.

  • DART impact altered Dimorphos’ orbit and shape, proving asteroid deflection technique viable

    On September 26, 2022, NASA’s Double Asteroid Redirection Test (DART) mission made history by intentionally colliding with the asteroid Dimorphos, significantly altering both its orbital period and physical shape. This is the first time humanity has purposefully altered the motion of a celestial object, as well as the first full-scale demonstration of asteroid deflection technology.
