Was it a mistake to prioritize The Moon and Mars?
Mars is covered in perchlorates, is generally inhospitable, and to cap it all off has 1/3 Earth Gravity. The Moon isn't much better, with the added bit that there's absolutely no protection from radiation on either planetary body. We don't know the "minimum dose" of gravity yet required for humans to thrive and reproduce, and we also cannot pretend that launching hundreds, maybe thousands of rockets (reusable or not) is good for our environment.
Was it a mistake to reorient Orion, SLS, and general NASA program hardware towards the moon and Mars instead of the original asteroid redirect missions that the Obama admin were pushing for? resources gathered from asteroids would be orders of magnitude more valuable to space exploration efforts being that they are already on orbit. We'd also have the ability to ensure Earth like gravity and environments through centripetal ring stations, alleviating various micro-gravity related issues that we've seen crop up on the space station.
Basically: are the Moon and Mars pipe dreams distracting us from what we should be doing? Gravity wells that will trap us in the folly of trying to adapt to another planet when in fact we should be bringing our environments with us?
