Man can't go anywhere without water, and space is no exception. Today, the drinking water of astronauts on the space station is still produced on Earth, and the cost of carrying supplies by rocket is much higher. Transporting water from the Earth obviously cannot meet the operational needs of future space facilities such as long-distance and crowded lunar bases.
The scientists say that the moon, the asteroid and other celestial bodies have abundant water resources, and the water can provide life support for astronauts, and can be broken down into hydrogen and oxygen as fuel to the passing spacecraft.
But how do we extract water from space? Is it necessary to transport the machines on the earth to drill wells? How is NASA going to solve this problem?
Make good use of solar energy to melt water and ice on the moon
This year, Transastra Inc. and George of the Colorado Mining Institute.
Transastra's project is called.
The reason why there is a large amount of water ice in the crater is that the terrain is low, the sun is not seen all day, and the temperature is very low. But the crater's edge is sunny all day. In fact, these pits are not deep, only about 100 meters from the bottom to the top. Therefore, Transastra's research team envisages building a water extraction base in the crater, inserting hundreds of meters high masts, and installing solar arrays on top to provide endless energy for the base. Because the surface of the moon has very little gravity, there is no need to worry about the batteries bending the mast.
The specific collection of water is completed by an electric roaming car. They stroll back and forth on the ice, emitting special rays consisting of radio, microwave and infrared rays, evaporating water ice through radiation, and recovering it by condensation. The researchers believe that the rover can be made up of a huge NASA
Transastra researchers believe that LPMO will greatly reduce the cost of building and maintaining a huge lunar polar base, an outpost that can serve as a beachhead for the industrialization of the moon in the United States, with the first and foremost priority being construction.
If LPMO needs to convert solar energy into electricity and then into radiation, Soworth's project uses solar energy directly. In June, he gave a speech at NASA's Future Space Action (FISO) team.
The Sovos team believes that this concept has tremendous potential for extracting industrial water for propellant production from the permanently shadowed region of the moon.
Cover the asteroid and distill the water inside
In addition to extracting water ice from the Moon, Transastra also has a project to extract water from asteroids, which is funded by NIAC, similar to the Solvos team's proposal to use concentrated sunlight to evaporate water from asteroids.
The difference is that the project requires a spaceship to capture asteroids directly and then use special
The project has entered the third phase, that is, to complete all the preparations for the demonstration task. Transastra plans to carry out the demonstration mission in the early 1920s, that is, to launch a code name of about 250 kilograms into low-Earth orbit.
However, the capture of an asteroid is

However, from NASA-funded projects, drilling wells may not be as useful as solar energy to get space water.
