No, no. There’s no mouse. It’s like that quasar water reservoir in space, where hydrogen and oxygen are slamming into each other around the black hole, creating a big ass ocean floating in the void.

It’s like that. But it’s the component parts of mouse jizz, just a giant, endlessly replenishing lake of rodent spunk, floating above the earth. A never ending source of protein for humanity to survive on, and use as an astonishingly effective hair gel, ala There’s Something About Mary Minnie.

Why go with one large mouse? What if we had a ring, like Saturn, but made of space mice instead of rocks?

The point of this experiment is the long-term preservation and storage of genetic material, not to answer whether or not we can reproduce in zero gravity. You’re familiar with the concept of a seed vault? It’s the same idea, just a different kind of seed.

That being said, who wants to bear the risk of medical complications from pregnancy 250 miles above the ground? It would not be an ethical experiment to intentionally do this. That being said, if it happened anyways despite protocol, you can bet your ass they’ll collect as much data about the pregnancy as possible.
