The impact of DART has revealed new insights into asteroid behavior

  • NASA’s DART mission successfully changed the shape of asteroid Dimorphos
  • DART impacted Dimorphos to test humanity’s planetary defense capabilities
  • The impact reshaped Dimorphos into an oblong watermelon shape
  • The asteroid’s axis of rotation shifted off-center
  • Up to 1% of Dimorphos’ mass was ejected into space
  • Dimorphos is a loose rubble pile held together by weak gravity
  • DART’s impact also altered Dimorphos’ orbit around Didymos
  • Dimorphos now rocks backwards and forwards as it orbits
  • DART’s success is a step towards asteroid-deflection technology
  • The European Space Agency’s Hera spacecraft will further study the asteroids

NASA’s DART mission has achieved a significant milestone in planetary defense by successfully changing the shape of asteroid Dimorphos. The deliberate impact of the DART spacecraft on Dimorphos has transformed the asteroid from a relatively symmetrical object into an oblong watermelon shape. The impact also caused the asteroid’s axis of rotation to shift off-center. Scientists have determined that Dimorphos is a loose rubble pile held together by weak gravity, which allowed it to be reshaped by the kinetic energy of the impact. Additionally, DART’s impact altered Dimorphos’ orbit around its larger companion asteroid, Didymos. The success of the DART mission marks a crucial step towards developing asteroid-deflection technology. Future studies of the asteroids will be conducted by the European Space Agency’s Hera spacecraft, which will assess the extent of the damage caused by DART and further investigate the nature of these celestial bodies.
