We Finally Know What China Found On The Far Side of The Moon

Added: 2026-05-26

[00:00:00]For years, most people assumed China's moon program was mostly symbolic. A few rover missions, some flags, a prestige project meant to show the world that China could reach space, too. But in 2024, something changed. Quietly, piece by piece, the curtain started lifting.

[00:00:19]On June 25th, 2024, China brought back 1,935.3 g of rock and soil from the far side of the moon. The first time in human history anyone had ever returned material from that side at all. The samples came from the south pole atken basin, one of the oldest and deepest impact structures in the entire solar system. Then came the renderings. For the first time, China and Russia publicly revealed detailed plans for something called the International Lunar Research Station, a permanent robotic and eventually humanup supported base near the moon's south pole. Chinese scientists began exposing experimental lunar bricks outside the Tiangong space station, testing whether materials made from simulated moon soil could survive radiation, vacuum, and brutal temperature swings in space. Then came the power plan. In May 2025, Rosscosmos and the China National Space Administration signed an agreement to study placing a nuclear reactor on the moon between 2033 and 2035 to power the future lunar base through the freezing 14-day lunar night. The missions aimed directly at the darkest places on the moon. Not the bright flat regions astronauts visited during Apollo, but craters near the lunar south pole that sunlight has not touched for billions of years. craters cold enough to preserve frozen water ice from ancient comets and asteroids. Water that could become oxygen, rocket fuel, and the foundation of a permanent off-world economy. For the first time, we are no longer guessing what China is building on the moon. The blueprint is finally visible.

[00:01:58]And if this works, the moon stops being a destination and becomes the first industrial outpost beyond Earth.

[00:02:09]Most countries that go to the moon focus on the landing. China focused on the system behind the landing. That difference changes everything. Back in the early 2000s, Chinese planners laid out a long-term lunar road map that stretched across decades. The goal was never a single dramatic mission. It was to slowly assemble every capability needed for permanent operations beyond Earth. First came Chang 1 in 2007. No landing, no astronauts, just mapping.

[00:02:39]The spacecraft orbited the moon for more than a year, building detailed topographic maps of the lunar surface and collecting the kind of geological data engineers would later use to plan future missions. Then came Chang 2 in 2010. Sharper imaging, better landing site analysis, higher resolution terrain models. Scientists could now identify dangerous slopes, unstable soil, and safer touchdown zones with far greater precision. Next, Chang 3. In 2013, China became the first country since the 1970s to soft land on the moon. The U2 rover rolled across the surface, collecting geological data that immediately suggested parts of the moon were far more chemically complex than previously believed. But the real turning point came in 2019. Chang4 landed on the far side of the moon, something many experts had considered nearly impossible because direct communication with Earth is blocked there. China solved the problem by placing a relay satellite called Quyo in a carefully positioned orbit where it could simultaneously see both Earth and the far side of the moon. Next, Chang A5 and Chang 6 sample return missions. Not just landing anymore, not just driving around anymore. Now, China was extracting material from the lunar surface, launching it back into orbit, docking autonomously above the moon, and bringing it all the way home to Earth.

[00:04:06]And the next missions go even further.

[00:04:08]Chang A7 is designed to hunt for water ice inside permanently shadowed craters at the South Pole using a hopping probe capable of leaping into terrain wheeled rovers cannot survive. Changi 8 is designed to test in situ resource utilization using lunar soil itself to manufacture bricks structures and possibly future habitats. Every mission was teaching China how to survive on the moon. It was less like a sprint and more like assembling a giant machine one piece at a time because the final objective was never simply visiting the moon. It was building infrastructure there that stays.

[00:04:49]For decades, humanity believed it already understood the moon. After all, NASA's Apollo astronauts had walked on the surface, brought back hundreds of kg of rock, and scientists had spent half a century studying those samples in laboratories around the world. Textbooks were written, geological models were built. An entire scientific story about the moon took shape. Then China landed on the far side. On June 1st, 2024, Chang 6 touched down inside the South Pole Atkin Basin, a colossal crater more than 2,500 km wide and believed to expose material from deep inside the lunar interior. Over the next few days, the spacecraft drilled and scooped 1,935.3 g of lunar soil and rock before launching the sample container back into lunar orbit, docking with a waiting spacecraft, and eventually returning the material safely to Earth on June 25th, 2024.

[00:05:49]The mission even left behind a strange signature that spread rapidly online in China. a sampling mark shaped like the Chinese character Jong, meaning middle or China. But the real shock came after scientists opened the samples. The rocks showed evidence of volcanic activity on the moon far more recently than many models predicted. One science paper published in late 2024 dated some of the far side basalt to around 2.83 billion years old, suggesting the moon stayed volcanically active much longer than previously believed. Another study suggested the lunar magnetic field may have strengthened again around the same period. Another found the far side mantle appears dramatically drier than the near side, implying the moon may be far more chemically asymmetric than scientists realized. In other words, the moon was not the simple geologically dead world many people imagined. It was more complicated, more active, more valuable. And suddenly these missions no longer looked like symbolic exploration.

[00:06:52]They looked like prospecting missions.

[00:07:01]When most people imagine the moon, they picture a dead world, gray dust, empty craters, a place astronauts visited once and left behind. But the most important part of the moon may actually be the one place sunlight almost never reaches, the lunar south pole. And what makes that region valuable has nothing to do with scenery. It has to do with darkness. The moon barely tilts on its axis. Because of that, sunlight hits the polar regions at an extremely shallow angle, almost sideways across the surface. Some crater walls near the south pole are so deep that sunlight never reaches the bottom at all. Not for a season, not for a century. In some places, not for billions of years. These are called permanently shadowed regions, and temperatures inside them can fall below minus 170° C, colder than the daytime surface of Pluto. For decades, scientists suspected those frozen craters were trapping something extraordinary.

[00:08:04]Water. Over billions of years, comets and water- richch asteroids slammed into the moon. Most of that water was destroyed by sunlight or escaped into space. But inside those permanently dark craters, the cold became a natural deep freezer. Molecules that entered rarely escaped. The result may be enormous reserves of ancient ice. Current estimates vary widely, but scientific models suggest the moon's polar regions could contain anywhere from hundreds of billions to potentially trillions of kg of water ice. And suddenly the moon stops looking empty. Because water in space is not just water. Water is oxygen. Water is hydrogen. Water is breathable air. And hydrogen and oxygen together form one of the most powerful rocket fuels humanity has ever used.

[00:08:57]That changes the entire equation.

[00:08:59]Launching cargo from Earth is brutally expensive because Earth's gravity is enormous. Every kilogram sent into deep space has to fight its way out of the strongest gravity well humans can currently launch from. But the moon's gravity is only about 16th of Earth's.

[00:09:18]If fuel can be produced directly on the lunar surface, spacecraft heading toward Mars, asteroids or deep space missions could refuel there instead of carrying everything from Earth. The moon becomes a gas station, a supply depot, a launch platform for the rest of the solar system. And that is why the South Pole matters so much.

[00:09:44]Finding water on the moon sounds simple.

[00:09:47]Just send a rover down into a crater and start digging. Except those craters are among the harshest environments anywhere in the solar system. No sunlight, no natural heat. Temperatures cold enough to freeze most electronic solid, jagged terrain untouched for billions of years, and almost no margin for failure. A normal solarp powered rover would struggle to survive there for long. So, China designed something different.

[00:10:14]Chang7 currently targeted for launch around 2026. It is one of the most ambitious robotic lunar missions China has ever attempted. The mission is not just one spacecraft. It is an entire coordinated exploration system. An orbiter, a lander, a rover, and something no country has ever operated on another world before. A hopping probe. The orbiter will circle above the south pole, mapping terrain and relaying communications back to Earth. The lander will touch down near the Shackleton crater region. A rover will move across the illuminated surface, searching for scientifically valuable targets. But the real star of the mission is the small jumping robot. Instead of relying on wheels, the probe is designed to leap directly into permanently shadowed craters that ordinary rovers cannot safely enter. It carries an instrument called L UWA, the Lunar Soil Water Molecule Analyzer.

[00:11:12]Its job is simple in theory and extraordinarily difficult in practice.

[00:11:16]Find usable water ice. The probe is designed for repeated hops of around 10 km at a time, descending into craters where sunlight has not touched the surface for over a billion years. Think about what that really means. Humanity has explored deserts, jungles, ocean trenches, Antarctica, even the deep vacuum of space. But these craters are something stranger. Places that have remained frozen and untouched since before complex life even existed on Earth. And China built a robot designed to leap into them.

[00:11:56]Finding water is only the beginning. The harder problem is construction because shipping building materials from Earth to the moon at scale is almost absurdly expensive. Every habitat wall, every landing pad, every radiation shield, every road, every kilogram has to survive launch, cross nearly 400,000 km of space, land safely, and keep functioning in one of the most hostile environments humans have ever encountered. Long-term, that model does not work. So, China is attempting something far more ambitious. Instead of bringing construction materials to the moon, it wants to manufacture them there. That is the purpose of Chang 8, currently planned for around 2028 to 2029.

[00:12:41]This mission marks a major transition in China's lunar strategy. Exploration is giving way to infrastructure. At the center of Chang 8 is a series of ISRU experiments in situ resource utilization which basically means using local lunar material instead of transporting everything from Earth. One of the most important systems is a solar concentrator furnace using focused sunlight. The device is designed to heat lunar soil to roughly 1,400 to 1,500° C. hot enough to melt regalith and turn it into solid construction material. In simple terms, China wants to bake bricks out of moon dust. The system is expected to 3D print structures layer by layer at roughly 40 cm hour. That may sound slow, but on the moon, even small autonomous construction capability changes everything. Landing pads could reduce dangerous dust clouds during spacecraft touchdowns. Protective walls could shield astronauts from radiation and micrometeorites.

[00:13:44]Roads could stabilize rover traffic across loose terrain. Future habitats could eventually be printed directly onto the lunar surface itself. And China is already testing whether these materials can survive space. In November 2024, experimental lunar brick samples were delivered aboard the Tanghou 8 cargo spacecraft and mounted outside the Tiangong space station for long-term exposure testing against radiation, vacuum, and extreme temperature swings.

[00:14:13]At the same time, Chinese researchers are developing autonomous robotic construction systems, sometimes referred to as Luna Spider robots, designed to assemble structures with minimal human supervision. This is the real shift happening right now. The moon is no longer being treated as a place humans briefly visit. It is being treated as a place where machines can begin building permanent systems before humans even arrive. And once robots can manufacture infrastructure using local resources, the economics of space change completely.

[00:14:47]At this point, the pattern becomes impossible to ignore. the mapping missions, the farside landings, the water hunt, the brick printing experiments, the communication satellites. None of these missions were isolated. They were all pieces of something much larger, an actual Luna Infrastructure Network. China calls it the International Luna Research Station or ILRS.

[00:15:12]And for years, many people treated it like science fiction. Not anymore.

[00:15:17]Official Chinese plans now openly describe a long-term station near the lunar south pole with surface facilities, orbital infrastructure, communication systems, navigation networks, transportation systems, and power generation. The stated goal is a basic model of the station by 2035, then a much larger expanded network stretching toward the lunar equator and far side by around 2050. 50.
