NASA scientists believe that once resources can be extracted from the moon, it will not only meet the needs of a lunar base, but the moon can also serve as a transit station for interstellar flight
According to Tencent Space (Luo Ji/compiler): At NASA's Kennedy Space Center in Florida, scientists are studying how to use raw materials from extraterrestrial celestial bodies to build colonies. Astronauts in future deep space missions need to use local materials to build bases . Josephine Burnett is the director of the Kennedy Space Center's Exploration Research and Technology Program. He believes that the development of space requires game-changing technology. At present, the Kennedy Space Center is developing some such new technologies. In the future, astronauts will no longer They need the earth to supply them with goods, and they should have the ability to be self-reliant and use the materials of extraterrestrial celestial bodies to build bases.
Jack Fox, director of science and technology programs, believes that if the deep space mission can achieve local material, then the spacecraft can be reduced by 40% of the departure mass. The resource utilization plan carried out by NASA is to use the material on extraterrestrial objects to build bases. Just like the early immigrants who arrived in North America, they only brought axes. They knew how to process trees into houses, so the immigrants came true. We believe that the use of extraterrestrial celestial resources can also be achieved. For example, the current 3D printing technology, once the input cost is reduced, then large-scale interstellar immigration will be possible.
In fact, extraterrestrial celestial bodies have many resources, such as water ice, metals, regolith materials, etc., which are all available materials, which can provide important help for the construction of lunar bases, Mars bases or other celestial colonies. Regolith is a loose material that covers the surface of rocks, including rubble, dust, etc., and is found on Earth, the moon, asteroids, and Mars. More critical is water resources. In 1994, the Clementine probe launched by Vandenberg Air Force Base found that there are water resources at the south pole of the moon, and in 1998, the Lunar Prospector mission also found that there are high concentrations of hydrogen in the polar regions. Lunar rover missions in 2008 and 2009 further confirmed the existence of more water resources on the moon.
The advantage of water is that it can meet the needs of human survival. At the same time, water can be used for fuel cell power generation. Hydrogen and oxygen are currently the most efficient chemical energy propellants. Once resources can be extracted from the moon, it can not only meet the needs of the lunar base, but also the moon. It can also be used as a transit station for interstellar flight, providing logistical support for humans to further explore around the solar system. At least so far, oxygen and water are necessities of life on Earth, and without them, we can't go anywhere. Since 1965, our unmanned probes have explored the major celestial bodies in the solar system. They are the pioneers of human beings, but in this century, we will focus on the surface of extraterrestrial objects, such as NASA is developing the RASSOR robot, Minerals on the surface of extraterrestrial objects can be mined.
