Last images from DART as it crashed into an asteroid

NASA smashed a spacecraft into an asteroid on purpose on Monday, and we all got a ringside seat. The Double Asteroid Redirection Test (DART) probe rammed into the harmless asteroid Dimorphos to test whether humanity could reroute a dangerous asteroid heading for Earth. DART took pictures every second as it approached the space rock. Telescopes on Earth watched the collision. And a tiny satellite flew alongside and photographed the impact, which took place 11 million kilometres from Earth. Studying its shots of the plume of debris that was ejected from Dimorphos will help scientists to understand exactly how the impact unfolded.
