We’ve equipped Mars with a laser. Our latest rover there, called Curiosity, actually shoots fricken laser beams from its head. How cool is that?
Is there a scientific purpose in aiming the rover’s laser at Earth and detecting the flash here? I think there must be. We could use it as confirmation that SETI’s laser detection scheme from a distant solar system would be viable. I seriously hope NASA is prepared to conduct this experiment.
Make sure the laser doesn’t zap a part of the rover itself. MAA doesn’t cover self inflicted LASER damage.
If Martians sent us a mobile, nuclear powered robot that shoots fricken laser beams from its fricken head, I’m pretty sure we wouldn’t be as gracious as they’ve been so far.

That c killed the cat thing is awesome. I also agree the martians have been awful nice. Martians aren’t cats, are they?
If they are, our robot will be their new overlord.
Earth’s cats have manged to reduce humans to servants. A laser wielding robot doesn’t stand a chance.
Curiosity seemed to handle that first one pretty well though.
