NASA Smacked A Spacecraft Into An Asteroid - What It Learnt From The Mission

In September 2022, the DART spacecraft smashed into the companion "moon" of a small asteroid 11 million kilometres from Earth. One goal was to find out if we can give such things a shove if one were headed our way.

NASA's DART mission – Double Asteroid Redirection Test – was humanity's first real-world planetary defence mission.

In September 2022, the DART spacecraft smashed into the companion “moon” of a small asteroid 11 million kilometres from Earth. One goal was to find out if we can give such things a shove if one were headed our way.

By gathering lots of data on approach and after the impact, we would also get a better idea of what we'd be in for if such an asteroid were to hit Earth.
