Is it really necessary to send humans to those places just to get the knock-on benefits? Couldn’t we do those things directly, without going there?
It seems to me that, today, those who have the money to spend on these endeavors would only do so if there were perceived short-term benefits to themselves. That means they plan to exploit the resources, or increase their own power somehow.
I know the good engineers that make this happen are doing it for the challenge and in the pursuit of knowledge, and I know that’s why we poors support it, but that doesn’t “pay the bills.” What is the motivation behind the money? Why are they really doing this?
The moon could be like an orbital gas station which is much easier to land and launch from compared to Earth (no atmosphere, less gravity). Building a buffer on the moon would make it considerably easier to ship mass to other planets. I don’t really see a way we build a Mars base without having succeeded on the Moon first.
This just pushes the question out one ring. What do we need to do on other planets that we can’t do on Earth?
The sad answer is there isn’t really anything. Go live on Mars and it will suck compared to Earth - no nature to enjoy, extremely limited variety of food, largely cut off from the rest of human culture and experience. After hundreds of years, it might be developed to look like suburban Ohio - you’ll have some iron mines and some Applebee’s and maybe enough people that the martian memes are fire … but you still won’t have a beach, or anything to see outside, or a blue sky.
It will just be Earth, but worse.
If people had had your attitude, humanity would still be huddled in one tiny corner of Eastern Africa, never having advanced past hunter-gathering. “Why go to that new empty valley over the mountains? First you have to get over the mountains. Then once you get there, there’s nobody there. You’ll be all alone. It will be just like our current home, but worse.”
If that one corner of Eastern Africa was the only habitable place on the planet, and getting to the next valley over required generations to live in suffering while available resources are used to make mountaineering gear, and settling that valley would represent a constant resource drain for centuries at a minimum…
Sure, same thing.
People didn’t leave Africa due to the moral imperative to explore, they did not have the resources to support large scale migration on a whim. They left Africa for food.
There’s no food on Mars, or the Moon.
Human expansion on Earth did require just the kind of investments you’re imagining. You’re just not using your imagination.
You couldn’t just immediately enter a new valley and start eating whatever you found there. Some things might be edible, but many could kill you. You encountered entirely different biomes than what your culture was adapted for, and you encountered new species that may or may not be habitable.
I imagine most expansion on Earth happened a lot like space colonization will happen in the future. When traveling to a new area, it probably started with exploratory expeditions. Small groups would go over the mountains and explore. Maybe they would bring back a few kinds of food to try. Maybe there they would find a few species they were already familiar with. (Similar to how there will be some resources we can use right from the get-go on Mars.) Later more regular expeditions would go, maybe once a year a group from the tribe would cross the mountains to gather some rare food type or animal skin. Over time, as people spent more time in the new biome, they did the hard work of figuring out what was edible. They did that hard painful work. And in time, they learned enough of about the plants and animals in the area to be able to safely gather enough food to sustain a population. It took generations. It was a learning process. A lot of people died in the process.
The thing you need to not forget about Mars is that we are no longer hunter gatherers. It doesn’t matter if we won’t find a garden of food on Mars, waiting for us to eat. We’re an advanced industrial civilization. We don’t gather food; we grow and manufacture it. What matters is not if there is food on Mars, but if there are the raw materials to support our food factories. Sure, settling Mars will require a lot more resources than hunter-gatherers than our ancestors needed when colonizing the next valley. But we also have a hell of a lot more resources and technology at our disposal than those ancestors did.
Say we put in all that effort, expend all those resources - what do we get for it?
Another place to put strip malls and parking lots. With the added benefits of brain swelling, heart atrophy due to the reduce gravity, and shortened lifespans from the increased radiation.
Or we could just, idk, make Earth a better place to live. If we have all these resources, surely it would be easier to make Earth more habitable given the much better starting conditions than to go to dead dust ball months to years away and try to live in an ant farm.
Just a thought
The problem is that you will never reach a point where you feel it’s worth expanding off of Earth. There will never be a point where things are perfect and all our problems here are solved. In fact, if we ever do reach that point, we probably shouldn’t expand out that point, as that means we’ve probably become a species of entirely self-obsessed narcissists that believes we are perfect.
Self-criticism is healthy. But you shouldn’t allow it to hold back your own life or your whole species.
I think you just have far to little faith in your fellow human beings. Thankfully history isn’t moved forward by naysayers. For every inventor that transformed the world, there were a hundred jealous naysayers that said it shouldn’t or couldn’t be done.
Just a thought.
It is only a “problem” if you consider space exploration a moral imperative.
I don’t. There isn’t anything up there that we can’t get easier down here. The resource expenditure is a poor investment. Not to mention how much this would further inequality.
If there will always be problems on Earth, then it sounds like we’ll never be bored staying here.
Frankly then, this isn’t a topic for you. Space exploration is not something that will be done by the entire human race. It’s something that will be done by those that believe in it. You and those like you can stay home and play video games while other people advance the human race. If you don’t get it, that’s a you problem.
Because exploration is in the human DNA. We seek to push out further, see and learn about new places, and further our understanding. Your question is like asking “why did explorers sail ships across the Atlantic when they had a perfectly good continent already?” At first, the new world was just “Europe but worse”, or the various islands of the Pacific were just “Asia but worse” - humans have always felt the need to explore and see what’s around every corner.
Sure, the Moon and Mars may be boring compared to all the sights on earth, but space exploration starts somewhere. Just like sailing the ocean, you start with learning how to build a boat that can cross a lake or river; you don’t start by building an ocean liner.
European exploration across the Atlantic was driven by a desire for trade routes with Asia that did not pass through the intervening Islamic civilizations that were often in conflict with the explorers, it was an economic motive. After the European discovery of the American continents, they were, in fact, largely ignored for about a century.
If exploration is so core to the human experience, why did the people of Asia - much more numerous than the Europeans even back then - not undertake any large exploration or colonization efforts? Or those of Africa?
The economic motive for space exploration is rather weak. There are asteroids full of valuable metals, but they are very far away and recovery would be more difficult and expensive than expanding Earth extraction efforts. We evolved to live here, life elsewhere disagrees with our biology - reduced gravity is great for your back and terrible for your heart and brain.
We don’t need the living space, and the population looks set to decline by the end of the century anyway.
While I understand you want to ascribe some kind of moral imperative to exploration, it is a large and completely unnecessary expenditure of resources that could be better deployed to make life here better for far more people.
You have deeply disappointed Admiral Zheng He. This may cost you your head.
And then he got back and they dismantled all the boats and never did it again. Definitely had exploration in the DNA.
And meanwhile the peoples of modern-day India, southeast Asia, Korea, Japan, Pakistan, Afghanistan, etc. never did this. Curious.
You’re a member of a species that owes its entire existence to exploration and expansion. We expanded from one biome in a tiny corner of Africa to a species of billions dominating an entire planet. We explored every corner of it and adapted to every possible biome. We learned how to live everywhere from isolate islands to endless deserts to polar wastes. We’re the ultimate explorer and colonizing species.
I cannot comprehend how a human being can look at that and then respond with the most bone-headed take imaginable, “we don’t have exploration in our genes.”
China engaged in all sorts of colonization. How do you think they ended up with Taiwan? India engaged in colonization in Sri Lanka and other areas. You’re just ignorant of history.
I believe you find yourself thinking that a lot if you don’t understand why people disagree with you.
Sorry, I just can’t wrap my mind around the motivations of misanthropic trolls. I have more faith in humanity than you do. You should try and find the good in other people rather than obsessing over the bad.
Exon Mobile on the moon. As long as they have some snacks I think it would do well!
