Lunar development is heating up again.

Since the completion of the Apollo program in 1975, lunar research seems to have had a tendency to be neglected. Recently, however, the situation has reversed. In a review article, Paul D Spudis from the Lunar and Planetary Institute in Houston, USA, elaborated on a new vision for space scientists and astronomers to develop the moon.

Three spacecraft are orbiting the moon: China's Chang'e-1, Japan's Kaguya, and India's Chandrayaan-1. A U.S. MOON-ORBITING SURVEY SATELLITE WILL BE LAUNCHED LATER THIS YEAR; Russia is developing a lunar rover; Germany and the United Kingdom have their own plans, in addition to participating in the European Space Agency (ESA) program; China and India are discussing launching a manned spacecraft to the moon in the next decade or so.

There are two reasons why the Moon is once again the goal of becoming a space power: (1) scientific developments have raised some new questions related to the Moon and (2) the Moon may offer opportunities for humanity in some ways. The Moon plays a key role in the development of the solar system.

Over the past 50 years, our space probes have flown past the boundaries of the solar system, and astronomers have further focused on the boundaries of the universe, the history of the universe, and the physics within it. However, the high cost of launch vehicle launches, coupled with the risk of failure, makes the implementation of space launch plans often affected by policy winds. A workaround is:

Reduce the number of launches, and use long-term satellites to complete the set tasks.

Future space development requires us to fly beyond the Earth's gravitational potential well, according to the space development plan approved by the U.S. Congress in 2005: new vehicles must go beyond the limits of low-Earth orbit and be able to serve many different types of research goals; the resumption of manned flights to the moon within 10 years; learn to live, produce, work on the moon (in another world); Use the knowledge and abilities gained to further explore the entire solar system. The most interesting aspects of this plan are:

Harness the abundance of resources found on the moon to create our new capabilities. In fact, solar energy has been powering vehicles since the early days of spaceflight; However, for the use of other lunar resources, such as water condensed in special environments, many professionals believe that:

That's an ethereal thing. In response to this kind of problem, SPUDIS believes that the moon is the "upper stone" for human beings to go to deep space.

He paints a hopeful vision map for us.

Alas, landlord, you will know all about these questions you ask.

The moon has almost no atmosphere, no magnetic field, weak gravity field and stable geological structure and other characteristics, the surface soil of the moon contains millions of tons of helium-3, helium-3 is an efficient, clean and safe nuclear fusion fuel, 1 ton of helium-3 produces enough electricity for all mankind for one year; The abundant silicon, aluminum, titanium, and iron on the moon are also huge reservoirs of future mineral resources on the earth.

I did too.

The Moon is the most thoroughly studied celestial body. The second celestial body that humans have ever visited is the Moon. The age of the Moon is about 4.6 billion years.

The Moon, like the Earth, has a layered structure such as a shell, mantle, and core. The average thickness of the outermost lunar crust is about 60-65 km. Below the lunar crust to a depth of 1,000 km is the lunar mantle, which occupies most of the moon's volume.

Underneath the mantle is the lunar core, which is about 1000 degrees warm and most likely molten. The diameter of the moon is about 3476 kilometers, which is 1 4 of the earth and 1 400 of the sun, and the distance from the moon to the earth is equivalent to 1 400 of the distance from the earth to the sun, so the moon is as big as the sun from the earth. The volume of the Moon is only 1 49 of the Earth, and the mass is about 735 billion tons, which is equivalent to about 1 80 of the Earth's mass, and the gravity of the lunar surface is about 1 6 of the Earth's gravity.
