"Yes, but why?" If humans had never ventured beyond perceived limits, like crossing oceans or building planes, where would we be today?

"We’re light-years away from being interplanetary; it’s too costly and our energy is laughable." If people doubted the Wright brothers or mocked the idea of landing on the Moon, should we have stopped trying?

"How far are we from affordable Moon travel that’s worth it?" Humanity thrives when it takes risks and embraces exploration. Space is where the next wave of innovation and opportunity lies, and waiting for "perfect timing" ensures we stay stagnant while others move ahead. Why choose doubt over progress?

We have no lack of spending opportunities for "progress"; there are dozens of promising research fields, and the ressources we can realistically invest are limited.

Most historical progress was driven and motivated by incremental gains; exploration as an end in itself was not even enough to get Columbus funded, and big space projects are much more ressource intensive than that.

> Space is where the next wave of innovation and opportunity lies.

That's just, like, your opinion. I consider this extremely unlikely; to me, the most promising fields short and mid-term are AI and synthetic biology. Space exploration does not even come close-- even if we magically gained the capability to build large scale, self-sufficient cities on Mars and populated them with millions of people (which is extremely unlikely to happen in the next decades)-- what does that do for us? What progress do we gain? If you want to build habitats in unlivable, hostile environments, you can just as well do this in Antarctica, some desert or the deep sea, and I'd consider that likewise mostly an exercise in futility.

edit: To make my position a bit clearer: I think its fine to invest "reasonably" in space exploration; the current moon project I'd consider mostly a waste, but still somehwat justifiable. But spending twice or more of what NASA currently costs on Moon or Mars base projects would be a non justifiable waste in my eyes.

1. What is a "reasonable cost," and who decides?

Reasonable cost is subjective, but NASA’s budget provides perspective. At 0.4 percent of the US federal budget, it amounts to just 27 billion dollars in 2023, while the defense budget is 842 billion dollars, or 13 percent of annual spending. Redirecting just 5 percent of defense funding, about 40 billion dollars, would more than double NASA's budget and allow for significant progress on Moon and Mars projects. This minor reallocation would not impact national security, making space exploration both affordable and worthwhile. When we consider the technological, scientific, and economic benefits, investing in space stands out as a smart, future-focused decision.

2. Are there any minerals on the Moon worth exploring?

The Moon holds valuable resources like helium-3 for clean fusion energy, water ice for fuel and life support, and rare earth metals for advanced technologies. Helium-3 could power nuclear fusion reactors and potentially yield trillions of dollars in energy benefits. Water ice can be converted into hydrogen and oxygen, creating rocket fuel that reduces reliance on costly Earth resupplies for space missions. Mining rare earth metals on the Moon could also lessen our dependency on Earth’s finite resources and help minimize ecological damage caused by terrestrial mining. The long-term financial value of these resources far outweighs the costs of extracting them.

3. Will Moon and Mars bases actually double NASA’s existing budget?

This claim is incorrect. The Artemis program, for example, is projected to cost 93 billion dollars over more than ten years, with yearly spending far below doubling NASA’s current 27 billion dollar budget. Additionally, technologies like reusable rockets, such as SpaceX’s Starship, have lowered launch costs by 90 percent, making Moon and Mars exploration increasingly achievable. With international collaborations and private investment, developing these projects is far less expensive than critics often assume, and will not significantly burden taxpayers.

4. What about other technologies, like AI or synthetic biology?

While AI and synthetic biology can offer exciting short-term benefits, they focus on Earth-based solutions and neglect humanity's long-term survival. Space exploration addresses critical long-term challenges, such as resource scarcity, reducing dependence on Earth, and avoiding extinction-level threats. Unlike efforts in Earth’s hostile environments like Antarctica or the deep sea, Moon and Mars exploration unlock completely new resources and pathways for innovation. Delaying investment in space exploration risks stagnating progress, and waiting for the "perfect time" could mean missing transformative opportunities that secure humanity's future.

Crossing oceans and building planes wasn't done for the sake of it, those goals were clearly useful.

The biggest problem of the moon mission isn't SLS, it's that the moon is a big dry ball of rock with nothing of any value or use there. There's literally no reason to go.

[vincenthwt]

Crossing oceans and building planes were not always seen as clearly useful by everyone. Skeptics at the time dismissed them as dangerous, impractical, or unnecessary, yet those who pursued these goals unlocked advancements that transformed human history. The same applies to the Moon. It is far more than just a big, dry ball of rock; it contains highly valuable resources with practical potential.

For instance, the Moon has helium-3, a rare isotope that could one day power clean nuclear fusion energy, a trillion-dollar industry waiting to happen. Lunar water ice can be converted into hydrogen and oxygen for rocket fuel and life support, making sustainable space exploration feasible and reducing the need for costly Earth-based resources. The Moon also has rare earth metals that are vital for technology and renewable energy systems, helping us address resource scarcity and reduce the environmental damage caused by terrestrial mining.

We do not explore the Moon for its own sake. The point of space exploration is to create a foundation for future industries and innovation while solving long-term challenges, such as resource depletion and planetary risks. Given the enormous technological, economic, and environmental benefits these resources could provide, the Moon is far more than just a barren rock; it holds the key to securing humanity's future.
