In December of 2018, the OSIRIS-REx spacecraft entered the gravitational influence of the teeny asteroid Bennu. Since then it's been taking amazing images of the wee world, showing us the face of this bizarre alien place.

But taking images is only one aspect of the mission. It will (very soon!) collect samples of the asteroid to return to Earth for study, for example. It's also mapping the minerals in the surface rocks.
