CCTV News: The National Space Administration announced on October 2 that at the 74th International Astronautical Congress, China's Chang'e-5 team won the "Lawrence Team Award", which is the highest team honor of the International Academy of Astronautics. Established in 2001, the "Lawrence Team Award" is one of the two major awards issued by the International Academy of Astronautics every year, aiming to recognize aerospace project teams that have made outstanding achievements in the field of aeronautics, mainly in three aspects: technological innovation, scientific discovery and international cooperation.
Chang'e-5 is the continent's first unmanned lunar sampling and return mission
At this conference, the National Space Administration announced that Chang'e-5 lunar scientific research samples will be open to international applications, and scientists from all over the world are welcome to jointly research and share results.
Hu Hao, chief designer of the third phase of the China National Space Administration's lunar exploration project and chief designer of the Chang'e-5 mission: The lunar sample has been recognized internationally, and some foreign experts and research institutions also very much hope to get this sample to carry out scientific research. We are organizing procedures and methods for how to implement these things, gradually opening up to the international community, and international colleagues can also participate in applying to study these samples obtained on the moon.
Chang'e-5 is the continent's first unmanned lunar sampling and return mission, which was the space system project with the highest complexity and the largest technical span on the continent at that time, breaking through key technologies such as lunar surface sampling, lunar surface take-off and ascent, lunar orbit rendezvous and docking and sample transfer, and jumping re-entry return, and brought back 1731 grams of lunar samples after the interlocking flight process, becoming the world's largest single sampling unmanned lunar sampling mission.
The National Space Administration has completed the distribution of 77.68 grams of lunar samples
Hu Hao, chief designer of the Chang'e-5 mission, introduced that through the Chang'e-5 mission, mainland scientists have achieved a number of important original achievements in the study of lunar samples. At present, the National Space Administration has completed the distribution of 6 batches of 258 lunar samples to Chinese scientists, with a total of 77.68 grams. He has published more than 70 papers in authoritative journals at home and abroad. Through the study of lunar samples, it was determined that the formation time of young basalt was 2.030 billion years, which is 800 million years longer than previously understood.
Hu Hao, chief designer of the third phase of the lunar exploration project of the National Space Administration and chief designer of the Chang'e-5 mission: The landing site, the lunar activity period and the original research on samples obtained by other countries are different, our landing site is relatively young, providing more evidence of lunar activity, expanding the understanding of the moon has played a very important role.
In addition, through the study of lunar samples brought back by Chang'e-5, Chinese scientists have rejected two possible magmatic genesis models in the late lunar magmatic activity in the source region of the lunar mantle, which are rich in radioactive elements to provide a heat source and water-rich to reduce the melting temperature of rocks. At the same time, we also discovered a sixth new lunar mineral "Chang'estone".
The mainland has accelerated the promotion of the international lunar scientific research station
The lunar exploration project that the mainland has completed so far also gives China the ability to explore farther deep space. According to the National Space Administration, at present, the mainland is accelerating the promotion of the international lunar scientific research station big science project, hoping that more international partners will join in.
Hu Hao, chief designer of the third phase of the National Space Administration's lunar exploration project and chief designer of the Chang'e-5 mission: We can not only go to the moon, but also conduct general inspection and exploration around the moon, we can also go to the moon, drive the "Jade Rabbit" lunar rover, and return to the earth after rendezvous and docking in lunar orbit from the moon. This series of technical support ensures that we go to other planets to expand the footsteps of human beings.
In addition, collecting samples from the moon can deepen human understanding of the moon and provide important technical support for the further use of the moon.
The National Space Administration said that the continent is accelerating the promotion of the international lunar scientific research station big science project, and at present, the cooperation initiative has been actively participated and responded to by nearly 20 countries and international organizations around the world.
The mainland will comprehensively promote the fourth phase of the lunar exploration project this year
The moon is the moon of the earth, it accompanies the earth and has attracted the attention of human exploration for thousands of years. According to the National Space Administration, this year, the mainland will also comprehensively promote the fourth phase of the lunar exploration project. At present, Chang'e-6 is carrying out research and development work as planned, and it is planned to be launched around 2024, which will go to the far side of the moon to collect lunar samples and bring them back to Earth, which will also be the first time that humans have obtained samples from the far side of the moon.
The Moon is Earth's only natural satellite, and studying the Moon can complement Earth science, not only to understand the Earth's past, but even to see the Earth's future.
Li Chunlai: The moon may be part of the earth splitting off, or it may be a twin, the moon and the earth are highly complementary or very similar, we hope that through the study of lunar science and lunar geology, we can better understand the past of the earth and the path of the earth's geological evolution.
Li Chunlai told reporters that by studying lunar samples, scientists have found that there are many chemical components and mineral resources similar to those on the earth, and these studies have important promotion significance for the earth's geology, physics and other fields. At the same time, lunar exploration is also expected to discover a large number of available resources such as water, metals and helium-3, providing important energy and material support for the future development of mankind.
News link: Review of China's lunar exploration project
China's lunar exploration project was established in 2004 and has successfully completed the three-step goal of "circling, falling and returning". Through a short video, let's review the extraordinary road that China has traveled to explore the moon.
The lunar exploration project was established in 2004, which opened Chinese real exploration of the moon.
In 2007, Chang'e-1 was successfully launched, taking the first step in the lunar exploration project, and China became the fifth country in the world to launch a lunar probe.
In 2010, Chang'e-2 was successfully launched, and after orbiting the moon, it entered the Sun-Earth Lagrange L2 point in 2011 to orbit and fly by the Tutatis, setting a record for the farthest flight of a Chinese spacecraft at that time.
In 2013, Chang'e-3 successfully soft landed on the moon with the "Jade Rabbit" lunar rover, setting a world record for the longest working time on the lunar surface.
In 2018, Chang'e-4 was launched and achieved the first soft landing on the far side of the moon by a human probe on January 3, 2019.
In 2020, the lunar exploration project Chang'e-5 was successfully completed, successfully obtaining 1731 grams of lunar samples, once again refreshing the altitude of China's spaceflight.
Continental plans to achieve a manned lunar landing by 2030
The timetable for Chinese astronauts to explore space has always been step by step, step by step. Starting from next year, almost every year until 2030, China's aerospace industry will show us new achievements.
The moon is very round and dazzling, Chinese the footsteps of surveying the sky and exploring the sky are very busy and brave, in the past, "people climb the bright moon cannot be obtained", now stepping on the moon and exploring the starry river, the unattainable bright moon will eventually reveal the mysterious veil to us.
