It takes light about 12 minutes to get to Earth from Mars, so whatever’s going to happen may have already happened.

Not sure that is correct on light speed. Transmission speed maybe?
It sounded way too long and this is what I found.

Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes. Closest recorded approach: 187 seconds, or 3.11 minutes. Farthest approach: 1,342 seconds, or 22.4 minutes. Nov 14, 2017
