Earth is hit by meteorites every day. Some are harmless, some could be dangerous. But now we have the most advanced tool to discover and predict them, the Vera Rubin Observatory. Will it be enough to predict a hit with enough precision to catch up a meteorite mid-flight? Finding out in this interview.
