markedup2 asked, “Are we doing this anywhere else?”

Assuming you are asking about other orbiters around other planets, the answer these days is, generally no. Juno is in orbit around Jupiter, but its camera is low resolution and the mission is not focused at imaging the planet. We presently have no orbiters taking images at Mercury, Venus, Saturn or beyond. And the other Mars orbiters don’t take images with the high resolution of MRO.

Are we doing this anywhere else? The spacecraft doesn’t seem _that_ large at about a ton.

Maybe when SLS gets cancelled (it really is just a matter of time), we can spend that money throwing these things across the solar system.
