Looks about that on my Replogle.
Interesting. I think you’re on to something here!
BTW, I was yapping with weighted Companion Cube yesterday, and realized that we already have proof that there was life on Mars.
Mars is red because the soil is covered with rust.
On earth, we had seas green with elemental iron. Rust didn’t happen until photosynthesis started dumping raw oxygen into the atmosphere. (It was our planet’s first ecological catastrophe).
So, how did Mars end up with enough free oxygen to rust the entire surface? The only model we have for converting a primordial methane/carbon-dioxide/dihydrogen-monoxide atmosphere into an oxidizing atmosphere requires life...
