I read this morning that NASA has a plan to get to Mars in 20 years. (1) If it takes 20 years, they will probably land at Elon’s third DragonPort and freshen up a bit at the local SpaceX hotel. (2) But that’s not the point. Once on Mars and cleaned up after the long trip, when those intrepid NASA explorers take a Model Y out for a run in the circumplanetary desert they will have no water, no trees, no animals, no oxygen, and a thin CO2 atmosphere in which to suffocate should their breathable air bottles spring leaks.
Which is to say, why bother? Our new EPA chief may be able to recreate this environment on Earth in less than 20 years and save a lot of money.
