  • AIDA (asteroid impact and deflection assessment) is a global cooperation that aims to test if we could save the Earth from an asteroid aimed at our planet.
  • It will target a small asteroid orbiting a bigger asteroid, floating 6.8 million miles away from Earth.
  • NASA will start with DART (double asteroid redirection test), launching a 0,5 ton craft in 2021 to crash into the asteroid 16 months later at 14,700 miles per hour.
  • It will release a satellite before the collision to take images.
  • European Space Agency will then launch Hera, which will arrive at the asteroid in 2028 with more tools to perform a detailed study of the asteroid after the impact.
