NASA smacked a spacecraft into an asteroid – and learned details about its 12-million-year history
NASA’s DART was the first time we tried planetary defence – attempting to redirect an asteroid. The data from this landmark mission is still yielding new insights today.
Not just space rocks: 6 things we’ve learned about Earth from meteorites and comets
Vast amounts of space rocks litter our Solar System, and sometimes land on Earth’s surface. There are many things we can learn from them.
