Let them have it.
I'm old enough to remember cool astronauts; guys like John Glenn, Neil Armstrong, Buzz Aldrin and others.
Now it's a bunch of random nobodies and even assholes like Mark Kelly, who looks like some creature from outer space himself.
There's nothing to gain except understanding of the universe, and evidently space telescopes do this well enough.

No, there's nothing to gain at all.
Manned space exploration, is stupid. It's got the sort of "neato" factor, but that's it.
There's literally no point in sending people to mars or the moon, and it's super expensive to do that. What have we discovered with the ISS? It's been up there for, what, 2 decades about? What discoveries have we made?
I know ONE - apparently you can eliminate bone loss by increasing resistance during exercise. That was worth a few 100 billion dollars to find out, right? And we can't go to Mars. Astronauts that are in space for 1 month, no matter what kind of physical regime they undergo, are invalids for days once they enter a gravity well again. It would take 3 months minimum to make it to Mars.

I imagine they've learned quite a bit in the space station. Much of it will be useful for future space travel, like maybe sending ppl to mars.

That's all we need is a bunch of french fried Chinese floating around in the Van Allen belt.

I have repeatedly challenged people to name any data that has come for the ISS.
Going to Mars is not a good idea, at least in the near future. To do that, we'd need, at minimum, a rotating ship to simulate gravity in a centrifuge. Once they get there, it's basically a year to stay before they can come back because of planetary alignment. It's not like going to the moon. Going to the moon is child's play compared to going to Mars and there's really no reason to do it other than PR points for whatever nation does it, provided the people sent there don't end up dying there.
We'd have to establish a semi-permanent base on the moon as a baby step. We'd need a rotating station and have people live in it for at least 3 months and see how well they do in a gravity well after. These are both tremendously expensive to do. Just having people live for 18 months WITHOUT supplies being added would be a challenge. We're nowhere close to going to Mars, and again, it serves no purpose other than propaganda.

Lunar samples collected by China’s Chang’e-5 probe are unveiling some new details about the Moon and how its resources can help Earth, the South China Morning Post reported.
In 2020, the Chang’e-5 lunar probe – named after China’s Moon goddess Chang’e – returned to Earth carrying nearly four pounds of lunar dust and rocks, the first samples to be retrieved in more than 40 years.
Since then, Chinese researchers have been carefully studying the samples and came across a new mineral. They reported that the particle – named Changesite-(Y) – was a phosphate found in lunar basalts and had a diameter of about one-tenth of a human hair.
Changesite-(Y) – also named after the goddess – is the sixth new mineral discovered on the Moon and its discovery makes China the third country to have discovered a novel lunar particle, after the US and Russia.
Scientists and officials explained that Changesite-(Y) could provide insights into the history and evolution of the Moon, as well as new details for deep space exploration.
But Changesite-(Y) is just one of the unique discoveries that astronomers made.
The collected samples were also found to contain Helium-3, a stable isotope of helium that many scientists say could be integral to developing new energy sources on Earth, Newsweek noted.
Helium-3 can be used to fuel future nuclear fusion reactors, an ambitious – but still nascent – technology that would provide greener energy for the planet.
Unlike existing nuclear fission plants, fusion reactors don’t produce dangerous and radioactive waste products.
Scientists have speculated that Helium-3 is abundant on the Moon and could be integral to Earth’s energy needs, although it would take many years until nuclear engineers could develop a reliable energy-producing fusion reactor.
