Correction: humans are overzealous pattern-matching engines.

Eh, we have other things as well. Meat for one. ;) Maybe you could say that we are meaty pattern matching engines.

Who said computers couldn't be made out of meat?

We've had the discussion: https://news.ycombinator.com/item?id=4261806 A cessna would need wings as large as a 747 and be traveling about mach 1 to take off, iirc.

Mach 1 where?

On Mars. Mach, the speed of sound (vibrations), varies with changes in heat, density, etc.

Mach 1 always means the speed of sound in the local environment.

I'd say we are proof that they can be. ;)

Saying that humans are pattern matching engines seems equivalent to saying VW Bugs are internal combustion engines to me though.

Pardon my idiotic question, but why don't they just drive over there and check them out? Or are they just in a totally different place than the rover (like asking why someone in North America can't just hop over and check out Uluru)?

That is not an idiotic question at all, it's a very good question. The reason is that (as you surmised) the rovers are very far away. Which begs the obvious question: why didn't they land a rover closer? That's a much harder question to answer. Landing site selection is a complex and somewhat political process. But there have been two polar missions, one successful, one not:

It really does. However, one should keep in mind that humans have overzealous pattern-matching engines. We are really good at erroneously seeing things that we recognize.

And when it comes to Martian geography, we are hopelessly bad at judging scale. It's very easy to be several orders of magnitude off without a guide or legend.

Google Mars, the hero Gotham deserves, but not the one it needs right now.

How could you make that comment and not link to http://www.terrybisson.com/page6/page6.html

Mars is an entire world, it's a big place, we only have two rovers on the planet and they can travel at perhaps 10 km per year.
