What's the point?
Humans have spent the last 60 million years carefully adapting to life at EXACTLY this pressure/temperature/chemical compilations and now you want to go into a sub-zero vacuum full of deadly cosmic radiation and material debris whizzing around at 100 miles a second? Just to satisfy some mundane curiosity about the PH levels of the soil on Mars?
What a fucking joke. Only NEET's with no concept of the vastness of space think interstellar travel is feasible, the few deluded schmucks too busy fapping to alien waifus to realize the futility of it all.
This isn't like mastering the ocean, a broad expanse of salt-water in a buoyant hunk of wood. This isn't like conquering the low-oxygen altitudes of the mountaintops with a $80 Parka you bought at Walmart. This is an infinitesimal expanse of fucking nothing but some dead rocks, gaseous wastes and incomprehensible pinpricks of condenses fusion. I am so goddamn sick of pot-brained burnouts thinking we can just toast this planet and fuck off to Mars with nothing more than a potted tomato plant.
Wake the fuck up.
