Nine days to the moon, how the myth comes into reality!
For thousands of years, human beings have never stopped longing for and exploring the moon. On January 23, 2004, China's lunar exploration program was officially approved, marking a new era of deep space exploration for China's aerospace industry.
Over the past 20 years, from taking photos around the moon, to landing on the far side of the moon by the world's first spacecraft, to successfully bringing back the "native products" of the moon, the three-step strategy of "orbiting", "falling" and "returning" has been successfully completed, making outstanding contributions to the cause of human lunar exploration.
The start of the lunar exploration project: Chang'e-1 and Chang'e-2
In 2007, the successful launch of Chang'e-1 ushered in the "orbiting" phase of China's lunar exploration program.
Chang'e-1 successfully entered the lunar orbit after several orbit changes and obtained high-resolution stereoscopic images of the whole moon, which is the first time that the Chinese have obtained their own scientific data.
This was followed by the launch of Chang'e-2 in 2010, carrying a high-definition camera to explore the moon in more detail. Chang'e-2 not only successfully completed the lunar exploration mission, but also went to the Sun-Earth Lagrange L2 point, opening a new journey of China's deep space exploration.
Moonfall phase: the breakthrough of Chang'e-3 and Chang'e-4
In 2013, Chang'e-3 successfully landed on the surface of the moon aboard the Yutu lunar rover, which was an important step in the "landing" stage of China's lunar exploration program. Chang'e-3 and Yutu carried out detailed topographic and geomorphological surveys on the lunar surface, and used radar to detect the underground structure of the moon, which provides important information for us to understand the internal structure of the moon.
In 2018, Chang'e-4 successfully landed with the Yutu-2 lunar rover in Von Kármán in the South Pole-Aitken Basin on the far side of the Moon, which was the first soft landing and roving survey of a spacecraft on the far side of the Moon in human history. The success of Chang'e-4 has not only unveiled the mystery of the ancient moon's back, but also opened up a new field for scientific research on the far side of the moon.
Sample Return: The Historic Achievement of Chang'e-5
In 2020, Chang'e-5 was successfully launched and returned, achieving China's first unmanned lunar sample return. Chang'e-5 landed in the Moon's stormy ocean region, completed automatic sampling, and brought samples back to Earth. This achievement not only demonstrates the maturity of China's space technology, but also provides scientists with a valuable opportunity to study the material composition of the moon.
Future prospects: Lunar Exploration Project Phase IV and Queqiao-2
With the continuous deepening of the lunar exploration program, China has begun to plan future lunar exploration missions. The goal of the fourth phase of the lunar exploration project is to establish a base on the moon and develop and utilize lunar resources. To this end, in March 2024, the Queqiao-2 relay satellite was successfully launched, which will become the new "Queqiao" between the Earth and the Moon, providing relay communication services for Chang'e-4, Chang'e-6 and other missions.
China's space station has entered normal operation!
On January 17, 2024, the Long March 7 carrier rocket, known as the "rocket train" of the space station, carried the Tianzhou-7 cargo spacecraft straight into the sky, sending the 2024 "New Year's Space Gift Package" to the Chinese space station.
In 2024, the mainland will also successively carry out two manned missions of Shenzhou 18 and Shenzhou 19, as well as the replenishment mission of the Tianzhou 8 cargo spacecraft. Among them, Shenzhou 18 and Shenzhou 19 are both composed of 3 astronauts. Through the four launch missions this year, China's space station will stage two in-orbit "shifts", and six astronauts will be stationed in the "space home" one after another.
With the "Space Home" equipment in place, the space station will start the normal operation mode. How will astronauts work and live in space?
What did the "courier brother" send to the astronauts?
The daily necessities transported by Tianzhou-7 this time are about 2.4 tons, mainly including astronaut clothing, food, etc., in addition to rice, noodles, various dishes, and dumplings. Of these, almost 90 kilograms of fresh fruit alone.
This is because of the long-term life in orbit, fresh fruits are the most popular food for astronauts. Due to the greatly increased carrying capacity of Tianzhou-7, the astronauts' desire to eat fresh fruits and vegetables has been satisfied.
What kind of fruit can astronauts eat?
Apples stand out from many fruits because they are nutritious, less juicy, shelf-stable, and easy to eat, and are added to astronauts' recipes.
In addition to apples, oranges, mandarins, pears, grapes, ready-to-eat juices: sugar cane juice, coconut water, and space recipes are also added.
What do astronauts do in space?
During the "space business trip", astronauts are like space farmers, planting various experimental crops and studying magical phenomena in microgravity. The three astronauts of the Shenzhou-17 crew, Tang Hongbo, Tang Shengjie and Jiang Xinlin, carried out two out-of-cabin activities during their time in orbit, and successively completed the established tasks such as platform maintenance, scientific experiments, aviation medicine, and experimental maintenance of the solar wing of the Tianhe core module;
What is the difference between the experimental materials sent by Tianzhou-7?
With the normal operation of the space station, Tianzhou-7 carried 61 scientific payloads with a total weight of about 473 kilograms, including 33 scientific experiments such as space life science, space materials science, microgravity fluid physics and combustion science, to support astronauts to continue to carry out space experiments.
Among the many experimental samples, the cell experimental sample is a special "passenger", and one of the experimental samples is bone marrow mesenchymal stem cells, which are used to study the phenomenon of osteoporosis in space. Bone loss in space will accelerate, and experiments can find out what biological signals will occur in bone marrow mesenchymal stem cells in the space microgravity environment, find intervention targets, and develop drugs or intervention methods for these targets.
In 2024, 20 years after the official establishment of China's lunar exploration project, the Chinese once again embarked on a new journey of lunar exploration.
Chang'e-6 is scheduled to take samples on the far side of the moon and return to Earth, while Chang'e-7 and Chang'e-8 will land at the moon's south pole to explore water ice resources, the moon's internal structure, and prepare for the construction of an international scientific research station. The success of these missions will bring a new leap forward in humanity's understanding of the Moon and lay the groundwork for future deep space exploration.
The romance of China's aerospace is hidden in every time you look up at the starry sky!
For the vast universe, the ancient Chinese had countless romantic imaginations. Now looking up again, those glittering names have brought ancient myths into reality one by one.
In the past, it was rumored that Chang'e ran to the moon and became an immortal, and the Jade Rabbit accompanied it and lived in Guanghan Palace together.
Today, Chang'e is the name of China's lunar exploration project, Yutu is our affectionate name for the lunar rover, Guanghan Palace is the area near the "Chang'e-3" probe after landing on the moon, and the three nearby impact craters are named craters, Taiwei and Tianshi.
Once upon a time, Zhu Rong was the god of fire in ancient mythology. "Wish" means forever, and "Rong" means light.
Today, Zhurong is China's first Mars rover. It ignites the fire of our interstellar exploration, and guides astronauts to constantly surpass themselves and pursue their dreams of the stars.
Wukong, who used to make havoc in the Heavenly Palace, is now a continental dark matter particle detection satellite; Kuafu, who used to chase the sun, is now a comprehensive solar detection satellite on the mainland; Jumang, the god of spring in folk mythology, is now a carbon detection satellite for the continental terrestrial ecosystem; Queqiao, where cowherds and weavers gathered in the past, is now the mainland's Chang'e-4 relay communication satellite......
"Dapeng rises with the wind one day and rises up to 90,000 miles" and "travels to the Yinque Pearl Palace, looking down at the accumulated qi" has become a reality, and "The sun and the moon belong to the stars and the stars?" The questions raised by the ancients about the vast universe are being responded to one by one.
We look forward to it
More Chinese myths become reality
We look forward to it
More Chinese footprints remain in space
We hope
More Chinese red shines in the universe
China aerospace, come on!
