chang e 5 lunar mission

Chang'e-5 collected lunar soil in December 2020. The sample point was located in the 43-degree northeast corner of the Storm Ocean, which was relatively young. Chang'e-5 used a combination of surface drilling to collect lunar soil. On one hand, it used a robotic arm to collect the soil on the surface of the moon. On the other hand, it used a drilling tool to drill the soil under the surface of the moon. In the end, the Chang'e-5 probe collected about 1.73 kilograms (1731 grams) of samples from the surface of the moon and successfully brought them back to Earth. This was the first time that China had achieved the return of extraterrestrial celestial bodies. It was also the first time humans had brought back samples from the surface of the moon after 44 years. The novel "Flood Dragon" is equally exciting. Everyone is welcome to click and read it!

In 2024, Chang'e 6 successfully brought back lunar soil. The Chang 'e-6 probe was launched on May 3,2024. On June 2, it accurately landed in the pre-selected area of the South Pole-Aitken Basin on the back of the moon and carried out sample collection. On June 4, the ascender ignited and took off, accurately entered orbit, and completed the rendezvous and docking and sample transfer with the orbiter and returnee combination. On June 25, the returnee accurately landed in the predetermined area of Siziwang Banner in Inner Mongolia, bringing back 1935.3 grams of lunar samples.

Chang'e 5 landed on the moon at 23:11 on December 1,2020 and brought back 1.73kg of lunar soil. The lunar soil was divided into two parts and three uses. Most of them were placed at the National Astronomical Observatory of the Chinese Academy of Sciences in Beijing, while the other part was kept in Shaoshan, Hunan Province. There were three kinds of uses: one was for scientific research; the second was to enter the national museum for public visits; and the third was that according to international conventions and cooperation agreements, some lunar soil might be given to friendly countries or foreign scientific research institutions as a "national gift". The Hong Kong Polytechnical University had successfully obtained lunar soil samples collected by Chang'e-5, including a 400-milligram surface shovel sample and a 42.6-milligram deep drilling sample. The harbin institute of technology had obtained 1330 milligrams, and Peking University had obtained 300 milligrams. In addition, scientists had made new discoveries in the lunar soil brought back by Chang'e-5, such as confirming the existence of pure carbon in the form of graphene, and discovering three micro-glass beads to rewrite the history of the moon for billions of years.

The most important mission of Chang'e-5 was to achieve China's first unmanned lunar sample return. The Chang'e-5 probe consisted of four parts: the orbiter, the returnee, the lander, and the ascender. The entire mission process included launch, moon landing, sample collection, ascent, rendezvous and docking, and return. It took more than 20 days from launch to successful return, which involved multiple separation and combination of the four components of the probe. Chang'e-5 was launched on November 24,2020. On December 17, the returnee successfully returned to the ground with lunar samples. This mission marked the successful completion of China's first extraterrestrial celestial body sample return mission and contributed to deepening human scientific understanding of the moon's origin and the evolution of the solar system.

In the Lunar New Year game, the "new moon" must be on the first day of each month in the lunar calendar. The "moon" was usually 14 days, 18 hours, and 22 minutes after the "new moon." The exact date of the start and progress of the game was determined by the lunar calendar. As long as the game could be launched between the first day of each lunar month (New Moon) and about 14 days, 18 hours and 22 minutes (Hope), there was no fixed Gregorian calendar date to correspond with.

There were many types of lunar spacecraft, such as the Soviet Union's LM lunar spacecraft and the United States 'Apollo program's moon landing spacecraft. The Soviets 'LM lunar spacecraft was an important piece of equipment in the Soviets' manned moon landing program. The Soviet Union had taken the lead in the early stages of the space race. In 1959, they sent the lunar probe, Luna 2, to the surface of the moon. In 1966, they launched a lunar orbit satellite. Its moon landing plan included a lunar spacecraft to orbit the moon and a lunar rover to land on the surface of the moon, but the plan failed due to various factors such as a poor rocket system. The lander of the LM lunar spacecraft could only carry one astronaut at first. There were problems such as simple functions and light weight. For example, astronauts could only observe the surface of the moon through a small window during landing. The take-off engine was the same as that of the moon landing, and the L2 lunar orbital module had no internal connection facilities between the two spacecraft to reduce weight. After the failed launch in 1971 and 1972, the Soviet moon landing program was forced to shelve. The Apollo program of the United States implemented a series of manned moon landing missions from 1961 to 1972. The lunar spacecraft consisted of a command module, a service module, and a lunar module. The command module was the control center, the service module had power and electrical systems, and the lunar module was used for astronauts to arrive and leave the lunar surface. The plan used the Saturn V launch vehicle as the final vehicle for landing on the moon. A total of six spacecraft successfully landed on the moon, and 12 astronauts stayed on the moon's surface, promoting human understanding of the moon. It also achieved the political goal of the United States to surpass the Soviet Union in the space field. The novel " Hundred Years of Spaceship " is equally exciting.

The lunar month was also known as the lunar month. It was the average period of the moon's revolution around the earth relative to the sun, and also the average period of the moon's phase. Its length was calculated based on the time interval from the new moon to the next new moon or from the moon to the next moon. The average was 29.53059 days, which was actually 29 days, 12 hours, 44 minutes and 3 seconds. Our ancestors called the cycle of the moon as a "new moon", and the day when the moon could not be seen at all was called "new day", which was the first day of each month in the lunar calendar. The day when the moon was the roundest was called "Wangri", which was the fifteenth (or sixteenth) day of each month in the lunar calendar. From the new moon to the new moon was the first half of the lunar month, from the new moon to the new moon was the second half of the lunar month, and from the new moon to the new moon was the lunar month.

There were 22 lunar seas on the surface of the moon. Except for the East China Sea, the Moscow Sea, and the Zhihai Sea on the back of the moon, the other 19 lunar seas were distributed on the front of the moon.
