What if there's a traffic accident on the moon?

Titan believes that Perovsk’s mining operation is releasing pollution and contaminating experiments, so they send a rover to investigate.

“They collide,” says Boggs. “Now everyone’s upset.”

Perovsk sues Titan over the damaged equipment in the International Court of Justice. Titan accuses Perovsk of breaking the law by polluting the moon. It’s unclear who should pay for what, and why. Rovers don’t carry insurance, and there’s a larger question about who has the right to use, or pollute, the moon in the first place.

Boggs says the case exemplifies one of her favorite things about space law: it’s ambiguous.
