A look at two missions attempting one of the most difficult feats of space exploration - to collect a rock from another world. This episode checks in on the US and Japanese attempts to bring a piece of an asteroid back to Earth. The missions have ... (more)taken decades of planning, but the results will be worth it. We find out how studying these space rocks can teach us about the origins of our solar system and may one day help save Earth from a catastrophic collision.
