Other than the thrill of exploration, I still can't see why some people are so fascinated with such a desolate planet. Interesting to see, but I would rather sit by the lake and enjoy a glass of wine (or two).

Out Of Thin Air: NASA Rover Makes Oxygen From Martian Atmosphere.

The Perseverance rover used an instrument known as MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment, which superheated the carbon dioxide to cleave it chemically, producing about 5 grams of pure oxygen – about enough for an astronaut to breathe for 10 minutes, according to NASA.

Baby steps.
One day they'll be growing and crushing grapes on Mars. And you know what that will lead to.

I started thinking about this story, extracting oxygen from the Martian atmosphere and it reminded me of my heat pump.
It extracts heat from -15 outside air and transfers it into my house.
We've come a long ways.

Don't believe Hollywood movies (i.e. "The Martian"). Martian soil is toxic. Nothing grows in that stuff. Not sure how would they fix that on a planetary scale.

It is pretty amazing stuff.

BTW: Your heat pump likely switches to auxiliary heat at around -6 or -7*C unless you have a fancy high $$ unit designed to work when others don't. But a heat pump specially designed to operate in lower temps certainly CAN work at temps as low as -20*

I am wondering, ... If humans were to colonize another place in space, why not the Moon? It is no less habitable than Mars, but it's much closer.

I’m guessing some people want more distance between themselves and the EX.

I believe it comes down to a couple of things:
1) Water has been found on MARS. Not sure if the same can be said for the moon?
2) MARS has an atmosphere.

Except that ...
1) You can drink water all you want, but eventually you need to eat something. Unless you bring it from Earth, there is no such thing up there.
2) Which is insufficient and totally useless to support anything, let alone life. No big difference from our moon.

It seems you're of the opinion that having easier access to water, and an atmosphere (albeit thin) isn't an advantage. I mean - water is only the building block of life after all and atmosphere does far more for us than just allow us to breathe. There's also gravity to consider. While still less than 1/2 of earth, it's still far better than the moon's 1/6th.

I'm sorry I didn't understand the intend behind your question. I thought you were curious and wanted to learn. I now understand that it was simply a disguise for accusing NASA and the likes of making poor decisions.

If you actually want to learn about why, perhaps ask questions instead of arguing with responses?
