In 1996, they knew exactly what would make or break moon colonization. Without lunar ice, you're hauling everything from Earth at massive cost. With it, you produce fuel locally and moon bases become economically sustainable. This wasn't about water for drinking, this is about extracting hydrogen and using it...

[Heo Seongbeom Youtube] 260305 Jin - Moon 🌕🌏 (part1) 👨‍🏫It’s a solo song by Jin, and BTS are also preparing for a comeback in March. I’m really looking forward to it. I’m the moon, and you are the Earth. So it becomes a kind of love triangle. Earlier the sea loved the moon, but who does the moon love? The moon loves the Earth. That idea is reflected in this song, so let’s try interpreting it. Since when have the moon and the Earth been together like this? We’ve been together for so long, but when did it start? About 4.51 to 4.53 billion years ago. Scientists figured this out through radioactive isotope analysis, which showed that the Moon is about 4.51 to 4.53 billion years old. “Shining just by existing.” This line is directed at the Earth. But does the Earth actually shine just by existing? No. Because the Earth is a planet and does not produce its own light. If the Earth appears to shine, it’s probably because of artificial lights made by humans. “Can I stay by your side and protect you?” It sounds shy, but in reality the moon can’t help staying there, because it’s bound by gravity. And here we see the main line of the song. “You are my Earth, and to you I’m just a moon. Your small star that lights up your heart.” It’s poetic, but is the moon actually a star? No. Celestial bodies are generally divided into two categories. First, there are stars (stellar bodies). These produce their own light. Second, there are planets. Planets do not produce their own light. Instead, planets usually orbit around a star. The Earth is a planet. From our perspective, the star in our system is the Sun. So when you look at the night sky and see stars, those lights are actually other suns, each producing their own light. But sometimes when you see a particularly bright “star,” it may actually be a planet like Mercury, Venus, Mars, or Jupiter. Then you might ask: if planets don’t produce their own light, why do they shine? Because they reflect sunlight. The Moon also appears bright because it reflects the Sun’s light. #JIN #방탄소년단진 방탄소년단

Jeff Bezos just described the Moon as a fuel depot, and the number behind it explains why nothing has ever left this planet cheaply. Bezos: “it has a very low gravitational field, only a sixth of Earth’s, which means it takes about 30 times less energy to lift a kilogram of mass off the Moon than it does to lift it off the Earth.” Thirty to one. That number rewrites the economics of everything beyond this planet. Every rocket ever launched has fought the same math. The fuel required to escape Earth is so heavy that most of what a rocket carries is the fuel needed to carry the fuel. The Moon breaks that cycle. It sits outside the well with water frozen in its shadowed craters, and water splits into hydrogen and oxygen. Hydrogen and oxygen are rocket fuel. Bezos: “the Moon is really a gift” Fill the tank up there instead of down here and the arithmetic of the entire solar system changes. Bezos: “So we can use the Moon as a rocket fuel depot to go to the rest of the solar system.” Not a destination. A gas station. Then there is the second constraint, which is that the sky itself runs on a schedule. Bezos: “unfortunately to get to other planetary bodies, they have very rare launch windows. Mars, you can go to Mars once every 26 months or so.” Miss the window and the answer is not next week. It is two years and change. Every world beyond our own operates on a timetable that does not care about human ambition. Bezos: “It’s so close to Earth. It’s only three and a half days away.” Except the Moon. The Moon is always there. Always reachable. That is what makes it the staging ground rather than the trophy. Apollo treated it as an endpoint, planted a flag, and came home. The flag was the mistake. A gas station is worth more than a monument. Monuments end the story. Infrastructure is what lets everyone who comes after take the trip for granted. Every era of exploration on Earth followed the same shape. Someone crossed once for glory, then someone built a port, and only after the port did ordinary people go. We have been staring at the Moon for three hundred thousand years thinking it was a destination. It was never the destination. It was the door. Every planet in the solar system just got closer. Not because the distances changed, but because the starting point did.
