Vera Rubin's keen eye on our solar system will inspire future missions

When the interstellar object (ISO) 'Oumuamua appeared in our solar system in 2017, it generated a ton of interest. The urge to learn more about it was fierce, but unfortunately, there was no way to really do so. It came and went, and we were left to ponder what it was made of and where it came from. Then, in 2019, the ISO comet Borisov came for a brief visit, and again, we were left to wonder about it.
