The point is the advancement of science, not simply the travel itself. Space science is integral to many advances we take for granted these days.

Yes, we need to do things like space exploration because these are the endeavours that advance humanity. Even in practical terms, plenty of discoveries that are useful here come from technologies developed for space exploration. If you're really worried about unproductive use of resouces, maybe worry about how we deal with the pedo elites that rule over us and hoard resources on unimaginable scale.

Space exploration falls into the category of "luxury spending" for me. Only when every human on Earth is fed, clothed and housed should we be looking out to the heavens.

not strictly necessary, no. but so is a lot of what we do today.

it'd be cool.

No, it's unnecessary and a waste of money

How else will we be able to someday mass travel through space to find another planet once we inevitably kill this one?

Well… short term no it’s not necessary (although as other folks have said on the thread it does give some technology advancements, and gives humanity a warm fuzzy sense of achievement)

Long term, it depends on the eval criteria

1. If we want the human race to live as long as possible, then I would say yes - to diversify, distribute and minimise the risk of planetary (Earth) failure
2. If we don’t give a toss about the human race then no, the Universe will be just fine without us

Yes, but I think the efforts right now should go into solving the climate crisis rather than going to the moon.

All attempts to discover how the universe works benefits us. Even a lot of really esoteric stuff has proven useful in fields like medicine and civil engineering.

yes. there's two branching discussions here:

• Space as a scientific topic, it needs to be understood. Our observation of reality is very local, and although we can prove that some of our assumptions about physics, life and civilization work on our neighborhood, it doesn't mean that they're the same everywhere. That alone is sufficient reason for me, to explore.
• Space as the new frontier. Many if not all exploration done on planet Earth has been, in some shape or form, resource-motivated. Lands, food, medicine, minerals, routes, are all found through exploration and normally through people spending money looking for a return over investment. Space is no different.

I think the interesting part is where this two branches touch: If we ever plan on capturing an asteroid for mining, the technology needs to be there to do it, and hopefully the technology is about the benefit of all humankind. This kind of development is showing us the way to move forward and solve problems. Imagine a world when we don't need to destroy ecosystems in order to get iron because all iron comes from off-world.

Spaceflight creates jobs.

Yes.

The impact to society from space exploration is immense if not immeasurable.

Absolutely and unequivocally yes. Nothing should constrain the boundaries of scientific study in space, especially now that our years are numbered due to climate change and dumbass fascists and dictators with launch codes. Whities on the moon, while a noble and valuable sentiment, should be altered to whities on patrol or something.

I’m so sick and tired of seeing Americans bitch about space exploration colonialism and remain silent on the colonialism that continues to kill and exploit Innocent people across the world.

Yes, we need better social infrastructure desperately, but that should come at the cost of terrestrial imperialism, not space exploration.

Necessary, yes. Furthering our knowledge of the cosmos is a worthwhile pursuit for its own sake. That being said, the sudden focus on NASA is pure political distraction, a clumsy attempt to foment nationalism that isn't going to be as effective as its architects were hoping.

Not really, it's more like a childhood dream that nobody investing will see IF it will give any results and/or is just a over expensive hobby, for the sake of have the knowledge of guessing of what is the planet that is over 5000 years light away from us might be made of. Who knows! It might have some form of H2O!

Necessary? No. Not much except eating, drinking and breathing is. Even reproduction is optional from the view of a single individual.

A good idea? Absolutely:

1. Exploring space tells us a lot about earth. We currently assume that the moon formed when something big collided with earth and threw lots of material into a stable orbit. This means moon is probably made of the same materials as earth and because there is no erosion nor tectonic activity on the moon, it lets us study what earth may have looked like billions of years ago.
2. Lots and lots of things that were originally developed for space are very useful on earth: teflon coating, memory foam matresses, efficient solar panels and many more. Sure, they could have been developed without space exploration but the pressure to get something exactly right helped a lot. And of course we directly use satellites for a lot of earth stuff, too. Think tv, weather prediction, monitoring of climate change, communication, GPS, accurate maps and many more.
3. It gives humanity something to unite behind. Even during the cold war, the USA and the Soviet Union ignored their feud for a bit to make Apollo-Soyuz happen. These days, the ISS is one of the biggest multinational projects and I dread the day it gets decommissioned because Russia will have one less reason to talk to the rest of the world.

Only if music is.

The cheapest way to maintain control over the globe via military force is to establish a moon operation that runs at only a slight deficit and hold the specter of lunar regolith asteroid strikes over every person on the planet earth.

Space exploration is not the only thing that generates spin off effects. It's not the only interesting science. Directly funding research into solving real problems actually works. So yes, I think it should be funded, but at this point, unmanned missions are a much better way to spend the resources: for the same money you get more science, more spin off, more everything. Just less spectacle. Space will not be profitable, or habitable in this century and that's fine.

Ultimately, space exploration is outside the realm of production and will stay there at least for a long time. Therefore, what we spend on it is part of our societal surplus: the value we collectively create, that is left over after reproducing society. What happens to that value should be decided democratically. But in capitalism, it isn't. Corporations control almost all the surplus and spend it on what's profitable for them. All of space funding in the US is just crumbs falling off the table of the military industrial complex mixed with the potential for propaganda.

For example, all those year, when Hubble was the best telescope, the imperial oppression apparatus had multiple of Hubble sized telescopes whose potential was wasted on intelligence gathering for wars. Then they got even better ones and offered a few of the left overs to NASA, but NASA couldn't even afford to make use of several free Hubble sized telescopes.

Space exploration is weight lifting for science.

Looking at the list of government expenditures, I don't see space exploration as problematic as other things we are spending money on.

From a risk assessment standpoint, space exploration is a VERY good investment. We need to be on multiple planets, preferably in multiple solar systems or even multiple galaxies.

BUT. It absolutely must be paired with NOT destroying the planet we have! This is the only planet we've got right now and the only one we've got a guarantee on habitability - if we don't fuck it up.

So yes, space is vital. But so it protecting this place.

There's a special kind of nerd that I call Puzzle Demons. They have big brains and they get satisfaction from solving puzzles without thinking about them. It doesn't matter what the puzzle is so long as it's a challenge to solve. They'll look back on their work with satisfaction because they solved the puzzle, regardless of what that work is.

Puzzle Demons in the 1940s built V-2 rockets. We gave them space travel and the puzzle became making the rocket leave the atmosphere instead of hitting cities. That space travel made helpful consumer technologies to survive in extreme environments, things that were otherwise too expensive for commercial R&D.

Then we killed NASA in the 1980s. The Puzzle Demons had no socially positive puzzle. They built the tech industry instead. I dated a Puzzle Demon whose fun little puzzle to solve every day was designing the UI for smart locks that go on the bunkers of the wealthy. She was thrilled to make locking herself out of the bunker more user-friendly. There are Puzzle Demons at the social media websites whose entire job is making them more addictive for children. Puzzle Demons gave us crypto, guided missiles, murder robots, AI slop, and corporate efficiency consulting.

We need space exploration to pacify the Puzzle Demons. Without it, the population is still encouraged to go into STEM but most of the STEM jobs are profoundly evil. You stick them in a NASA office and they're just building useful things. Otherwise the prestige jobs are with defense contractors, tech companies, and multinationals.

Yes. Because I want an alien girlfriend.

Yes, absolutely, science in general is necessary for any kind of desirable civilization. Space exploration contributes a massive amount of knowledge to scientific research and betters the human race.

But it shouldn't be a playground for billionaires to plan space hotels for ultra-wealthy clientele. Public works for the public good, for the betterment of our human race as a whole, not just for the super rich.

Space tech can be dual use, as military tech to destroy usa. This way we can explore space, and solve the problem at home as well.

Yes

Setting aside all the intangible benefits such as answering why we are here and providing inspiration to generations there are tons of short and long term benefits.

In the short/medium term, research is so much about solving problems and your solutions having unexpected applications in other areas. A lot of our minituarization in tech happened because we needed things smaller and lighter to lift into space, think things like your smart phone camera or laptops. Also things like cordless tools and even memory foam were originally developed for their application in space travel.

In the long term, let's take a look back, what if we had the same stance when we looked at the ocean, and thought why its even necessary to figure out how to navigate the waters. For our species to propagate or even survive, we need to expand. Right now we are one decently sized asteroid from extinction, but if one day we figured out how to expand to multiple worlds, then we become a heck of a lot of more resilient.

I am of the opinion that space exploration and settlement is the single most important thing humanity should be doing. Currently humanity exists only on this planet, which through the course of its existence has had numerous mass extinction events. It is hubris to believe that we will never be affected by one. Right now all of humanity's eggs are in this single basket, and if that basket gets kicked over, humanity could cease to exist.

Now I will grant you that there are lots of things down here on earth that we should be spending money on to better the lives of humans generally, but these things are not mutually exclusive. Right now we're spending orders of magnitude more money and resources waging war on one another than space exploration. In the US in 2025, the US military budget was around $920b, whereas NASA's was $25b. The military budget was 36 times higher than the space budget. It's not even close. Space is not where dollars are being wasted.

Studies have also shown that NASA's impact is a net positive on the economy, consistently generating more economic impact than is put into it. It creates well paying jobs that employees find fulfilling and satisfying, generates public interest in the sciences, and benefits society as a whole as new technologies are developed that we all get to enjoy.

I would argue that what we NEED to do is stop needlessly murdering each other over religious and social disagreements, and spend our resources on feeding, clothing and taking care of one another such that we all have the time, security and ability to watch humans go out into space with wonder in our hearts.

We came from the stars, we should learn about our origins.

It is a virtual certainty that at some point a meteor large enough to wipe out all multicellular life on the planet will strike the Earth. It is an absolute certainty that the Sun will eventually burn out leaving the planet uninhabitable. Something else might wipe out our species long before either of these things happen, but it's not a bad idea to have another inhabited planet or two as a backups.

We had problems on earth before space exploration, and we’ll have problems on earth after space exploration. And if we colonize other planets we’ll have problems there.

Because every time humans solve a problem they create more, bigger, harder to solve problems.

Space exploration doesn’t affect this.

Yes but we need to treat the earth as the only habitable place we will ever have and run sustainably. We need to be using less than one earth year of renewable resources each year and use a minimum number of non renewable. I don't think we should be sending people into space all that much. We should as much as possible seek to learn how to mine, process, and produce in space. Its certainly something we cannot do now but if we are ever to make any real progess it will have to be something we figure out. Its also likely the best direction for the resources we put to space as far as return. By that I mean the same way much of our technology was spurred by the space race due to the challenge of getting out into it and to the moon. I feel learning to mine and automate in space will have the greatest returns in technological advancement for us. I think ideally any time we send people to space whe have a destination built already for them to go to. So send rovers and such to the moon and try to excavate and build a dome or such and install equipment. I mean if we could figure out a way to automate making rocket fuel in space and could make fuel depots that would be huge. I also want to experiment with things on the moon. Like I think we should make a moon space elevator. Not because its a very necessary thing for the moon but to figure out the tech. maybe later we try to make one on mars. if we made them on a variety of space objects we might get sure enough to do one on earth.

1. The amount of money spent on NASA is negligible compared to the MIC
2. Human intuition about what STEM stuff is useful is very poor. The basis for your ability to securely do online banking is a quirky little number theory equation that was useless for centuries. Or think about the reactionary complaints about “they’re paying scientists to study cat urine” or whatever. Those studies typically have a practical reason for getting some and practical implications once they’re finished. Even the stuff that is practical looks impractical to the layperson. Space travel is very similar in that the technology it enables can have other uses.
3. Whoever figures out asteroid mining first is going to make a lot of fucking money

Many people find hope in exploration, discovery, and pushing physical frontiers. These were necessarily parts of human history that shaped our intuitions and desires and I think without new frontiers people get cynical or bored that can lead to some awful behaviors and outcomes. It's the same with scientific research it doesn't need to take the majority of the public funds but there is a minimum especially for some planetary scale science efforts.

We have so many problems to fix isn't a good reason not to explore and inspire, I'm sure there were ancient people who thought investing in roads was a waste of public funds why do we need to connect to other cities or lands if we have problems already, but some of those problems were resolved with trade or treaties or pluralistic cultures the roads allowed.
