China also does this. We just don't hear about it because they also quash the reporting.
These are smart people, they’re not going to make major life decisions based on simplistic takes from political opportunists.
And kicking people off of twitter and facebook for similar banned thoughts?
It’s fine to talk about a “race” if jingoism is the thing that gets most people on board with funding Nasa. But we ought to know better.
They are co-occurring facts in the same area and the only reason China’s success is relevant in this discussion is because it is co-occurring with and in the same field as the American decline that is (unlike the tangential Chinese angle) directly relevant to the story here.
So, in this specific case, if we are going to mention China at all, the answer is yes. Not because the two things are so linked that they ALWAYS need to be discussed together, but because that is the relevant nexus between the present subject and China at all.
And ironically the US very much considers itself to be in a race with China including in space, it's just run by such thundering morons that most of the moves they make advance China's interests more than theirs. Now the cancellation of Mars Sample Return isn't that big an issue in terms of strategic benefit or decline narratives, nor is it a particularly massive surprise (the program's issues are longer term than just current administration cuts). But there is a certain irony in some of the people most interested in scorekeeping with China (and for that matter Mars!) being the ones likely to ensure China pulls off the sample return first.
The Chinese rise is also remarkable in its own terms, but it's not the subject of discussion here. The subject here is how the US is under cutting its former preeminence in science.
People took issue with the cost of space exploration in context of "the good the money could do here on Earth", but then when we shifted resources that way, the money did absolutely no good here on Earth.
What view do you have on the trajectory of the U.S.? Is America ascending or declining?
The success China is having isn’t something that’s occurring in isolation. There is a void and they are filling it.

This would be funny if it wasn't happening in real life. Clearly they did "ctrl-f diversity" and didn't actually read what they were cancelling.

No need to. Mars delivers:

I think the Trump admin decided since it will not make them a profit, like other scientific research already canceled, it is not worth doing.
It was supposed to launch in 2018, then was pushed to the early 2020s on a Russian rocket. For obvious reasons, it got pushed again, now launching in 2028.
The state of the world isn't great for space exploration, but I'm hopeful this mission will be revived at some point in the future.

With the price of launches so low compared to only 20 years ago due to advancements in launch technology and the increased cadence of launches it seems like it should be easier to do these kinds of missions and that there should be more, cheaper missions that are willing to take risks because the per mission cost is so much lower.
Can you comment on why that doesn't seem to be happening? Why aren't we covering Mars in cheap rovers and satellites?
In fact, that kind of standing order for a new Curiosity every year is exactly how you would keep the technology alive in practice.
And as others have said, there is really no such thing as a cheap rover. As a recent example, there was recently a push by NASA HQ to refurbish a Mars rover engineering unit (basically a one-to-one copy of the one sent to Mars, kept at JPL for use in ops planning and issue debugging) into an operational lunar rover. The estimated cost to take this existing piece of hardware and make it fully flight ready and suitable for the new mission was hundreds of millions of dollars.
Seems that the reduced cost is being taken advantage of. And, make sure to exclude the drastic reduction in non-lunar launches in your cost comparison for lunar launches.

In space everything is an orbital change. To change orbits you need to speed up and slow down, all of that requires fuel. Even using what are known as "low energy" trajectories that use a bunch of gravitational slingshots need velocity changes to adjust trajectories to get the right angle of approach to some large body.
Most commercial launch services focus on LEO because the secondary stages don't need to carry much fuel and their engines only need to fire reliably once to get into a stable orbit.
A planetary transfer requires multiple engine firings. That's much harder than a single reliable firing. It's not impossible but the testing and engineering is expensive.
A science mission often needs to beg, borrow, and steal to get built. There's one shot to accomplish the mission objectives. That's more expensive engineering and testing. Some mission profiles require specific planetary alignments with very narrow launch windows to boot. So there's a lot of expensive work made more expensive by a tight deadline.
The actual marginal cost of the rocket, fuel, and launch is a very small part of the mission cost. Halving the launch price doesn't necessarily affect the cost of anything else.
Starlink satellites are effectively disposable. If a Falcon 9 explodes or fails to get the second stage to orbit they're out maybe a few tens of millions of dollars. If a science mission has some mission-killing failure there's no funding for a do-over.
I’d be interested in working there to help accelerate the program but I’m not if I would get support internally.
Do it !
It says they have two sets of every sample: One onboard and one in the designated drop area.
The drop area is a backup: if the rover dies while travelling somewhere, the return pickup mission would not be in the right spot.
* Storing all the samples onboard means a larger and heavier rover
* Mass budget squeeze means no more helicopter
* The return requires a ground launch from mars, so no more SkyCrane delivery system
Who are these "powers that be"? And do they have an infinite credit card? Could they really just do whatever they want and for some reason they choose not to?
The "powers that be" chose to lose a completely optional and ill-conceived war on your dime. Instead of science or helping people they decided to spend money blowing up schoolgirls.
The reason why NASA ended the Apollo program is because the American public 1) was never as committed to Apollo as younger people seem to believe they were with most people being indifferent to it and plenty of people being outright against it as wasteful, and 2) even the modicum of support it had on the Apollo 11th landing was gone by the next mission. Famously, Apollo 13 was notable for regaining the attention of the public, which it almost certainly would not have had if it weren't for their lives being on the line.
The public has almost never voted for more funding to NASA. The Kennedy Administration put a shitload of money into NASA hands, without real public approval, for geopolitical goals. It was never for public anything. The public just cannot be assed to spend even a few dollars on things they don't like, and they've never cared for generic space science.
The general public can in fact do whatever they can manage to fund, including through enormous debt, which is how we spent like $40 trillion on stupid wars in the desert for no reason. I was never really in agreement with doing that, but for some reason such a suggestion was "Unamerican", as claimed by the very people bitching about the debt right now. Who just so happened to be mostly the same people voting on doing those stupid wars.
It doesn't matter how many games you want to play with how "the system" makes it hard to vote for the right people, or how the incentives are constructed, but even in such a system, the Trump power bloc is still based around voting people out if they get in his way. The power always comes down to voting. The people in our government do all the shenanigans they do because it's how you capture the votes. They pander to giant businesses because those businesses pay for their political ads, which always go up in price so that only the largest businesses can afford to control them. But politicians do it because those ads get them the votes. If just doing their job better got them more votes, they would do that, or be replaced with someone who would.
The powers that be are the voters, with caveats and nuance.
Maybe in some ideal world the US and China would work together to pass those samples on to a Chinese MSR, but it seems borderline impossible.

Which of the 180ish elements would possibly be found on a foreign body in enough scale that couldn't possibly be found, made, or replaced by cheaper means here on earth?
Space mining doesn't make sense! We can't even justify exploiting all known resources here on earth itself because they aren't profitable, how do you work those numbers when, instead of literal slave labor, you have to pay the energy cost of going up and then back down for every kilo of matter?
If it's often not worth it to mine literal gold here on earth because it can't be profitably extracted, the core limit on gold mines as an investment and business venture, why would it be profitable to, for example, mine that gold on Mars and try to bring it home?
That cancelled program became famous for leaving behind an already bought launcher that now will fly mass simulator

Excuse my French
Flying to Mars and then flying back is incredibly complicated and much more expensive. Rather than sending an exploratory rover or a satellite, you have to basically send an entire launch vehicle when we've never launched anything into orbit from Mars before. And it has to operate essentially autonomously (for the launch).
Even missions to get samples from comets and asteroids are far less complicated because you're not dropping into a gravity well with just enough atmosphere to cover all your stuff in dust but not enough for atmospheric braking. Mars has the exact wrong amount of atmosphere.
Obviously samples returned from Mars would be better but it diminishes the value when we already have samples here. So the huge price tag and incredible engineering complexity becomes harder to justify.

I was holding my breath for Nancy Grace Roman Space Telescope which amazingly wasn't cancelled but they did cancel its successor, the Habitable Worlds Observatory Space Telescope which would be able to spot earth-sized exo-planets
even though Congress already funded it, because somehow the executive is allowed to illegally pocket veto Congress over and over again past two years
it's all Heritage Foundation and Russell Vought, he has no use for science and education
And I mean I agree, for that much money we should be doing missions to Europa instead.
Mars has a little bit less gravity than Earth
How big would a rocket need to be even to send a small payload (let's think 20kg/45lb) even suborbitally so that it can be caught by another spaceship
Now check how big a rocket has to be to send all of that from Earth
You'd probably have to send this on Starship. And refuel it while on orbit
It would jeopardize important national security projects like the White House Ballroom, the Triumphal Arch, the Garden of Heroes and National Golf Course, and of course the Donald J. Trump Center for The Performing Arts (formerly The Memorial To That Loser That Got Assassinated.)
What makes you think the poster you responded to agrees with the Iran war expense? He simply commented on how difficult it is to cut anything from the Federal budget. He's right. Remember when all the lunatics were out keying Teslas a few short months ago?
