NASA's little DART satellite hit its target asteroid 11 million kilometres away. Hooray!

Now begins a process of observation and analysis to measure what impact it had on the asteroid's trajectory and if such a system could be used to defend our planet.

This - the final image from the satellite - is what success looks like.
