on a planet quite literally perfectly designed to promote our survival, we would be able to survive on another planet.
People love to argue about the little stuff, but if you look at where American taxpayer money ends up (I say American because that's where I live and what I'm familiar with, not because I'm not aware other countries exist) our military expenditures absolutely dwarf everything else. NASA, the cost of healthcare, the cost of college education, and even smaller, even more hot button issues like welfare, that's all peanuts compared to what we spend on military. That's not to say I don't support our soldiers but come on, if there's fat to trim that's the place to look! I'd like to stop blowing up other places for a bit and focus on home.
We will probably blow ourselves up here eventually anyway. If humans manage to spread to another planet it won't take long for fighting to break out there too, only if it's a completely lifeless planet that we colonize there won't be the huge diversity of other species around. I suspect at least the first several attempts at colonizing another planet will fairly quickly end in catastrophe of one sort or another. Eventually something might work out but I think we're a long way off.

I have in several threads mentioned the mysteriously disappearance of 21 trillion USD getting ridiculed by your fellow citizens for it now you trying to make point of very same Pentagon spending and you didnt know it was 21 trillions, as if i dont know how the corrupt USA works. The soldiers is not yours but the oligarchs mercenaries im not baffled you support such pathetic criminal crap! There is a reason USA is the planet laughing stock so MAGA and Covfefe!
Have you figured out why your so called fellow soldiers still invading and stationary in Afghanistan do you?

How is this not the single most important thing being investigated by Congress?
It’s all about who owns Congess Dave.

The only answer IMO is full public financing of elections and once you leave congress, a lifetime ban on lobbying or working in any industry you were involved in regulating. I know, it will never happen, but I can dream...

The really sad thing is that our Congress critters have been so successfully bought (or so successfully sold themselves) that these numbers are hardly influential. While the numbers in the chart look huge, they are a tiny fraction of the net worth of all but the newest and least influential, even if focused on only a couple of people.
. But under US law, corporations cannot donate to political campaigns. (They can donate to allegedly-independent PACs, but that is not what this chart describes.)
If you've ever donated to a political campaign, you are required to disclose the name of your employer.
Remember, for a federal campaign, a US citizen is allowed to contribute something like only $4600 to each candidate.
So the real money influence on campaigns comes not from individual donations, but from the super PACs legalized by the Citizens United decision, which basically allowed unlimited money contributed by anonymous people to run "issue ads" supporting preferred candidates and blasting opposition. The real money influence comes from lobbyists who can promise "jobs" in a district , and they can sweep that PAC money to a candidate.
NASA's budget is absolutely tiny in the grand scheme of things, it's no wonder they haven't undertaken anything really monumental in a long time.
I think space is fascinating, but unlike many I'm not so enamored by the idea of sending people to Mars. Even under the best conditions, it's a less hospitable and far more isolated environment than the most climate-extreme, desolate "corners" of the Earth. What exactly is someone who goes there going to do? I suspect the novelty of being on another planet will wear off pretty quickly once they get there. If an emergency occurs, they are on their own, even if we were to send them needed supplies it would take months for them to get there.
I would be more interested in sending unmanned robotic probes to more places. It's much cheaper and less risky, and we can send them to far more places, learning much more than we can by putting a human on Mars. Exploration can be mechanized and automated, the only reason to send a human there is because we can.
I didn't like Andy Weirs new book about the moon as much as The Martian, but his description of a practical colony on the moon sounds at least realistic compared to setting up a Mars colony.
We can get a lot more tonnage to the moon much cheaper and quicker, and tourists could take realistic two week long vacations there.
Mars is more hospitable to larger scale colonisation for sure, but several orders of magnitude more tricky.
Colonising Mars? No atmosphere, no magnetic field, no water. Terra-forming isn't realistic. I guess you could have people living in pressurised underground structures. But how would the colonists construct them and set up the necessary manufacturing facilities and mining operations (for the raw materials) without massive support from Earth. It's not going to happen any time soon.

There are all sorts of scientific reasons to send humans to Mars. Nearly everything that happens to those humans in that environment, and much of what they see and do, would be scientific data that's unobtainable anywhere else. It doesn't stop being science just because it's expensive as hell and may not happen in our lifetimes.
But the same data can be collected by robots for a fraction of the cost and risk, so there is no reason to send humans.

Let me know when a robot can collect data on how humans function in a Martian environment without having humans in a Martian environment.

Why not? What a human would be doing is collecting rock/soil samples and operating the measurement equipment that was prepared back on earth. A robot (remote controlled from earth) can do that as well (that's what the mars rovers have been doing). A human might be better at it but not enough that it motivates the extra cost/risk.

The answer is - not that much. Something very simple for a human often is extremely difficult for a robot. Robots are good for doing tasks which are easily automated and need high volume of repeated operations. But general tasks are extremely difficult for them.
