When we think of the lunar probe Chang'e-5, we often think of its successful return of samples to Earth, marking a huge milestone in China's space history. However, a recent study has groundbroken another surprising discovery of the Chang'e-5 mission – the connection between water and some mysterious element.
This mysterious element was once suspected of being present in the Apollo program, but was never openly discussed. What did the scientists discover this time? Is there some kind of secret connection between the two? Let's dive into the unspoken matter and unravel the mystery of Chang'e-5.
The Secret Behind the Apollo Program: Why Has the Apollo Program Failed to Reveal the Existence of Water on the Moon?
It is worth noting that the Apollo program was implemented in the 60s of the 20th century, when the technology was much less developed than today. The detection equipment and instruments at that time were relatively rudimentary and could not provide sufficiently accurate data. Therefore, if there are trace amounts of water molecules on the Moon, there is a good chance that they will be ignored or misunderstood.
With the goal primarily focused on landing and returning safely, the Apollo program focused on surveying the Moon's geological structure and surface features in order to provide the basis for future exploration. Finding liquids such as water was not a priority at the time. As a result, the Apollo program had relatively limited surveys of water resources.
The environment of the Moon is extremely harsh, with extremely low surface temperatures and strong solar radiation. This means that water molecules on the Moon may exist in a solid form, or they may be tightly bound to rocks and soil, making them difficult to detect directly. The detection equipment and technology used by the Apollo program did not have enough sensitivity to solve this problem.
Through these missions, scientists have found that there are craters containing water ice on the surface of the moon, ice in Antarctic craters, etc. These discoveries provide important resource support for the establishment of a lunar base in the future. In fact, access to water is essential for future lunar exploration and deep space exploration, where water can be broken down into oxygen and hydrogen not only as a drink and plant plant, providing astronauts with breathing and fuel.
Chang'e-5 mission: Why did Chang'e-5 choose the south pole of the moon for exploration?
The South Pole region of the Moon is rich in scientific value. The south pole of the moon is the shadow region of the Earth, and it is also a place where the sun's light cannot directly reach it. The temperature here is very low, which can reach around minus 230 degrees Celsius. Due to the lack of sunlight, the surface here is in a constant state of darkness.
There may be a large amount of icy water in the South Pole region of the Moon. Water resources are very important for the future survival and development of human beings in space, so Chang'e-5 chose the south pole region of the moon for exploration to find and verify the existence of these ice water resources.
The South Pole region of the Moon is of great significance for the exploration of lunar caves. Scientists believe that there may be many huge caves in the south pole region of the moon. These caves could provide protection against radiation from space and could also be ideal places for humans to establish a base on the moon in the future. The Chang'e-5 mission includes the exploration and exploration of these caves, in order to provide strong support for the subsequent exploration and use of the moon.
The South Pole region of the Moon also has unique geological features. Scientists believe that the south pole region of the moon may be rich in mineral resources, such as hydrogen, oxygen and other important resources, which are of great significance for the subsequent activities and development of human beings in space. One of Chang'e-5's missions is to help scientists better understand the geological structure and resource distribution of the moon's south pole region by collecting samples and conducting field analysis, so as to provide a scientific basis for future resource development.
The choice of the region of the south pole of the moon is also related to the environmental factors of the planet. Due to the relatively flat terrain of the south pole region of the moon, the landing conditions are relatively good, which provides a good guarantee for the safe landing of Chang'e-5. In addition, the south pole region of the moon also has a longer sunshine time and less lunar dust, which is very beneficial to the work and protection of the Chang'e-5 probe.
Water Detection: How did Chang'e-5 look for traces of water?
Chang'e-5 is China's first lunar sample return mission, and its goal is to collect samples from the lunar surface and bring them back to Earth for study. In this important mission, Chang'e-5 also undertook a key mission, which is to detect the presence or absence of water on the surface of the moon. Water is of great significance in space exploration, not only providing drinking water and oxygen for astronauts, but also potentially becoming an important resource for future deep space exploration.
Chang'e-5 is equipped with a high-resolution camera, and by photographing the surface of the moon, scientists can observe the possible presence of water. Water is usually found on the surface of the moon in the form of ice, so scientists look for special landforms related to ice. For example, the Moon's South Pole region is considered to be the most water-rich region, so the camera will take a more intensive picture of this area in order to catch any water-related signs.
Chang'e-5 also carried a microwave radio frequency excavator, which can detect the water content of the moon's surface by emitting microwave signals and receiving the reflected signals. Due to the high dielectric constant of water, it will have a significant reflection and absorption of the microwave signal, so that the instrument can judge the presence or absence of water based on the strength of the reflected signal. Using the data from the microwave RF excavator, scientists can map the distribution of water on the surface of the moon and further understand the distribution of water resources.
In addition to the above two methods, Chang'e-5 also uses laser positioning and velocimeter to detect water. Laser locator and velocimetry can determine the distance between the detector and the target by emitting a laser beam and measuring its return time.
Through multiple measurements, the position and velocity information of the target can be obtained. In the process of detecting water, Chang'e-5 will use laser positioning and velocimeter to scan the surface of the moon, and if it finds that the surface features of certain areas match those of water-bearing areas, then there may be traces of water.
For a mission like Chang'e-5, the accuracy and reliability of the instrument are very important. Scientists have carefully designed and rigorously tested the instrument to ensure that it can work properly in the harsh environment of space and provide accurate data. During the actual exploration process, Chang'e-5 will continue to maintain communication with the ground control center, transmit the detection results in a timely manner, and make corresponding adjustments and decisions based on the results.
Analysis of Lunar Soil Samples: What Truth Does Chang'e-5 Reveal About the Moon?
The Chang'e-5 mission is part of China's lunar exploration program, which aims to collect and bring back lunar surface samples to Earth. On November 23, 2020, Chang'e-5 successfully landed on the surface of the moon and returned lunar soil samples to Earth after sample transfer at the deep space exploration station in Lanzhou. The results of the analysis of these lunar soil samples have attracted extensive attention and research. So, what exactly does Chang'e-5's mission reveal about the moon?
Through the analysis of lunar soil samples, scientists are able to gain insight into the composition and evolutionary history of the Moon. The composition of chemical elements in lunar soil samples can reveal the composition and proportions of lunar surface material.
For example, the content of certain elements may be related to the original material that was present at the time of the formation of the Moon, while the presence of other elements may be due to a comet or subsequent impact event. In addition, by analyzing the rocks and minerals in lunar soil samples, scientists can infer the geological evolution of the lunar surface. This is of great importance for solving the mystery of the origin and evolution of the Moon.
The Chang'e-5 mission has provided strong support for the development and utilization of lunar resources. During the analysis of lunar soil samples, scientists also discovered some important mineral resources. For example, lunar soil is rich in oxygen, iron, titanium and other elements, which can be used in future lunar base construction and space exploration missions.
There are also resources such as water storage ice and hydrogen on the Moon, and the discovery of these resources is undoubtedly a huge breakthrough for space exploration and deep space navigation. The mission of Chang'e-5 has laid a solid foundation for the continued exploration and use of the moon in the future.
The results of the Chang'e-5 mission will play an important guiding role in the future lunar landing program. Through the analysis of lunar soil samples, scientists are able to better understand the environment and characteristics of the lunar surface.
This is an important reference for subsequent lunar landing programs, including the design and operation of human lunar landings and lunar probes. In addition, by analyzing the tiny cosmic dust and gas composition in lunar soil samples, scientists are also able to study the origin and evolution of the solar system, leading to a more comprehensive understanding of other celestial bodies beyond Earth.
