Will nuclear power plant pollute the moon? NASA said it was not sure



If the launch of the Soviet Union’s satellites in the last century and the manned landing of the United States on the moon ignited the space dream for mankind, then, as time enters the 21st century, the development of human science and technology has gradually made man’s space dream a reality. According to reports, NASA recently proposed a new future plan: before 2026, a nuclear power plant will be built on the moon. Then, the question is, is it feasible?


NASA will build a nuclear power plant on the moon

In terms of moon exploration, NASA has always been at the forefront of the world. From 1969 to 1972, the United States conducted 7 manned moon landings, including 6 successes and 1 failure, bringing back a large number of precious samples from the moon for mankind.

Entering the 21st century, with human beings becoming increasingly dissatisfied to live on the earth forever, NASA has once again set its sights on the moon. When it returns to the moon in 2024, the moon reconstruction plan will also be launched.

However, NASA sincerely invites many countries to join the international community. After all, there are many people and great power. Japan, Canada, and many other countries are now members of NASA’s Artemis project.

In addition to returning to the moon, a permanent human base will be established on the moon by transforming the moon. Not only that, a space station will be established in the orbit of the moon, and the moon will also become a “springboard” for NASA’s manned landing on Mars in 2030.

Take this plan to build a nuclear power plant on the moon. This plan includes the construction of a flight system, lander, and nuclear reactor on the moon’s surface, and if the lunar nuclear power plant is successfully completed and put into use in the future, then, when the United States goes on Mars in the future, And will also build a nuclear power plant on Mars during the transformation of Mars.


Can a nuclear power plant on the moon be successful?

Although the moon is very close to the earth, there is still a distance of 380,000 kilometers. Therefore, if you want to build a nuclear power plant on the moon, you need to obtain materials from the moon. Otherwise, if the required materials are transported from the earth, then it is feasible Sex is not great. However, the construction plan given by NASA shows that all the facilities of the nuclear power plant will be built and assembled on the earth, and will be transported to the moon after finally passing the safety test.

In this process, the flight system and lander mentioned above will come in handy. When a nuclear reactor device, more specifically, a nuclear fission power system, will be fully functional after it passes the test. Through the flight system, it is connected to the lander and finally reaches the surface of the moon.


In this way, even if there is no permanent staff on the moon, after the completion of the nuclear power plant, it can continue to operate normally on the moon and provide energy for mankind.

So, what is the purpose of this? In this regard, NASA said that when the lunar nuclear power plant is completed, humans can begin to transform the moon, because the nuclear power plant will bring enough power to the moon and will also help mankind realize the “Moon Migration Program.” According to the researcher, the lunar nuclear power plant will operate on the moon for about 10 years, and according to the current development speed of mankind, 10 years is enough to transform the moon.


Will nuclear power plants pollute the lunar environment?

Although it seems to be a good plan, will the construction of nuclear power plants on the moon cause pollution to the lunar environment? This problem is also a problem that many people worry about.

We all know that once a nuclear power plant leaks on the earth, it will cause a large area of nuclear radiation pollution. Although there is no life on the moon, if the nuclear power plant has an accident, it can pollute the environment on the lunar surface. In this way, humans If you are in a nuclear radiation environment after landing on the moon, you will naturally be in danger.

NASA has no way to give a positive answer to this question, because the environment on the moon is changeable, especially if a meteorite hits the moon after the nuclear power plant is built, then the possibility of the nuclear power plant being destroyed is also greater.

However, the moon, including the construction of nuclear power plants on Mars in the future, is also a key step in the process of human space migration, especially Mars, because if humans want to completely turn Mars into second earth, they need to simulate it on Mars. The atmosphere of the earth makes Mars warm and humid.

Should this be done? It is necessary to build nuclear power plants and chemical plants on Mars, and emit large amounts of greenhouse gases through combustion, so that the Martian atmosphere becomes thicker and warmer.

However, will there be a nuclear leak that will pollute the climate on Mars? This question cannot be answered either. Just like when a nuclear power plant is built on the earth, no one will be 100% sure that a nuclear leakage accident will not occur. Take Japan’s Fukushima Nuclear Power Plant as an example. Before 2011, it was the largest nuclear power plant in the world. Destroyed by the earthquake, nuclear radiation pollution still exists today.

Tianwen-1 completed the fourth midway correction of its orbit and returned the first image of Mars



At 20 o’clock on February 5, 2021, the engine of the first Mars exploration mission Tianwen-1 probe was ignited, and the fourth midway correction of the ground fire transfer section was successfully completed to ensure that Mars capture was carried out as planned.

Up to now, Tianwen-1 has been in orbit for about 197 days, about 184 million kilometers away from Earth, about 1.1 million kilometers away from Mars, and a flight mileage of about 465 million kilometers. The probe systems are in good condition.

Prior to this, Tianwen-1 acquired the first Martian image at a distance of about 2.2 million kilometers from Mars.

The potential mass range of dark matter is narrowed, helping to focus the search area



According to a report by the physicist organization network on the 27th, British scientists used the fact that gravity acts on dark matter to fundamentally calculate the mass range of dark matter for the first time. This range is much narrower than previously thought. The latest research has narrowed the range of potential masses of dark matter particles and also limited the search range for future dark matter “catchers”. It will also help scientists discover potential new forces in the future.

Dark matter does not emit light, emit electromagnetic waves, does not participate in electromagnetic interactions, and cannot be directly “seen” with any optical or electromagnetic wave observation equipment. Scientists have confirmed its existence through the effect of dark matter on galaxies. The result of the cosmic microwave background radiation observation experiment gives the proportion of dark matter in the total amount of cosmic matter. In the universe, ordinary matter accounts for only 4.9%, dark matter accounts for 26.8%, and dark energy accounts for 68.3%. Dark energy and dark matter are also considered to be two dark clouds in the physics sky at the beginning of the 21st century.

In the latest study, the research team led by Professor Xavier Kalmot of the School of Mathematics and Physical Sciences at the University of Sussex assumed that gravity is the only force acting on dark matter, and calculated that the mass of dark matter particles is between Between 10-3eV (electron volt) and 107eV, it is much narrower than the theoretically expected 10-24eV to 1028eV.

“This is the first time anyone has used quantum gravity to calculate the mass range of dark matter,” Carmott said. This study shows that unless there is a hitherto unknown force affecting it, dark matter cannot be like some theories. It is said to be “ultralight” or “overweight”.

The researchers believe that this research will benefit physicists in two ways: one is to focus on the search area of dark matter; the other is to help reveal whether there are mysterious unknown forces in the universe-if the mass of dark matter is found to exceed in the future The range predicted by the Sussex team indicates that dark matter is affected by other forces in addition to gravity.

The collapse of some marine species: sea surface temperatures continue to rise under multiple pressures



A zoology study published on the 28th in the British “Nature” magazine pointed out that some marine species are facing a crisis of “population collapse”-since 1970, the number of marine slatyfish in the world has decreased by 71%. Among these marine species, More than three-quarters of them are on the verge of extinction; and another study published at the same time pointed out the “climate crisis” of the ocean: global sea surface temperature has been rising for the past 12,000 years.

The ocean is facing multiple pressures. Issues such as climate change, rising sea temperature, pollution, overfishing, and ocean acidification have been affecting the health of the ocean. Scientists currently believe that the risk of marine species extinction should mainly come from overfishing. However, the reduction of individual species has always been difficult to measure. Although the reduction of marine and coastal plategill fish populations in different regions of the world has been recorded before, there has been no global development. analysis.

This time, the Simon Fraser University team in Canada estimated the relative abundance of 18 marine slaty fish species from 1970 to 2018 and assessed the extinction risk of all 31 marine slaty fish species. They found that from 1970 to 2018, the global abundance of marine slaty fish fell by 71.1%. Among these 31 species, 24 are on the verge of extinction; 3 shark species have declined especially, and are now classified as critically endangered—this is also the most threatened species in the World Conservation Union (IUCN) list The grade.

The researchers blamed the reduction of these species on fishing pressure, which increased 18 times during this period. The research team pointed out that immediate action should be taken to prevent “population collapse”, and specifically called on governments to implement fishing restrictions to help promote species recovery.

In the climate report published on the same day by the journal Nature, the Rutgers University of New Jersey team pointed out the “climate crisis” of the ocean. According to the report, the global average annual sea surface temperature has been rising for the past 12,000 years.

The researchers reinterpreted the two latest climate models this time and devised a method to assess the seasonal deviation of a single record, and then calculate the annual average sea surface temperature. They found that climate warming from 12,000 to 6,500 years ago was caused by the retreat of the ice sheet, while recent warming was caused by the increase in greenhouse gas emissions. The current temperature is the highest in the past 12,000 years. The temperature was similar during the last interglacial period about 125,000 years ago.

In addition to suggesting that emissions have caused the sea surface temperature to continue to rise, this study also fills a long-standing gap in the gap between climate models and data used to reconstruct historical climate changes in the Holocene.
