On: SpaceX craft overshot Mars’ orbit and is headed to...

If that roadster hits Mars and seeds Mars, that would be huge and interesting for science. Mostly because "How did something survive in space for that long?"

True, but by that time it won't be our science, it will be descendants-of-our-dolphins' science. Or aliens-from-outer-space science.

Seriously, the only way I can see humanity not getting to Mars before the Roadster is if we completely fail as a species.

Also "how did a plastic car survive reentry?"
