The Japan Aerospace Exploration Agency’s Hayabusa2 spacecraft has fired a copper cannonball into an asteroid in order to learn more about the composition. Now, a year later, the results are in from over 195 million miles away. The cannonball contained a small camera to capture a detonation that then took place in the asteroid. Images can be seen showing material that appears to be similar to sand shooting out of the crater. The asteroid’s gravity kept the material from completely floating away as it was pulled back into the hole from the cannonball.
