A total of a species broadcast in the world ｜ Send an invitation letter from China Space Station, please click to check it

If someone asks you what there is in the sky and the ground?

Maybe you can answer immediately:

Stars and sun, flowers and grass

If you ask you, how to make space grow flowers

Can you still know the answer?

Human beings stood on the earth and space. They continued to deepen each other's connection for thousands of years. Wanjia lights moved the galaxy to the world, but it seems that it is not easy to make space like the earth and the earth.

However, don't be discouraged. The progress of science and technology can always make it impossible to become possible. Human beings have already taken the first step in space plants in space. The little friends may not wait to have a series of questions and want to ask: Can the seeds of plants come to space to germinate, grow, bloom, and produce seeds? Can these plants growing in space be used to supply astronauts? What is the difference between plants and ground plants in space?

To know that the answer is actually very simple. From September 9th to October 30th, under the guidance of the China Manned Aerospace Engineering Office, the Science Communications Bureau of the Chinese Academy of Sciences will jointly organize the "A total of a capacity of the world to broadcast a piece of the world. Season — Purpose of plants with astronauts with astronauts, follow us, answer your doubts!

Asked: "As the first experimental cabin, space life science experiment, see me!"

Speaking of asking the sky, everyone must be familiar with it. On July 24th, the Chinese Space Station asked the Tiangtian Experimental Curring to successfully launch and dock with the core compartment of the core cabin. Such a scientific experimental cabinet.

They support the advanced platform of space science experiments. Life ecological experimental cabinets can provide corresponding cultivation environment and life protection for plant, aquatic biology, small model animals, and small mammals. The biotechnology experimental cabinet supports the development of biotechnology and application research with biological cell cultivation and tissue construction, spatial protein crystals, protein and nucleic acid co -origin, and spatial biomechanics.

The China Space Station will be completed this year, which will provide a comprehensive experimental platform with larger scale, long -term care, device sample replacement, and wide coverage. It will become the national space laboratory. The comprehensive development has made contributions.

So, the platform and technology are all available, are you afraid that the plants will not be germinated?

Ask the sky: "Xiao Nan, Xiaowei, I want to take you to the sky!"

On July 24th, the questioning of the scientific experimental cabinet was launched, and this time scientists and engineers arranged a "big house" for Xiaonan and Xiaowei. Zheng Huiqiong Research Team, a molecular and excellent Innovation Center of the Chinese Academy of Sciences, undertakes the "Molecular Mechanism of Higher Plants Flowing and Regulating Molecular Mechanism under micro -gravity conditions".

There may be many friends who are puzzled. Who is this Xiao Nan and Xiao Wei? In fact, their true bodies are naman mustard and rice.

On July 28, experimental units containing experimental samples and rice seeds were installed in the general biological training module installed from a astronaut to the test of the experimental ecological science experimental cabinet of the Tianshi experimental cabin. On August 29th, for a month, Arabida mustard and rice seeds were successfully germinating and growing seedlings at the China Space Station.

As soon as the news came out, it immediately attracted a lot of attention and discussion on the Internet. It is expected to achieve the first international cultivation research on rice in the whole life cycle of rice from seeds to seeds. At that time, the seedlings ("Xiaonan") had multiple leaves, and the seedlings of high straw rice had grown to about 30 cm high, and low -straw rice ("Xiaowei") also grew to 5 to 6 cm high.

This also makes everyone very curious. What is the difference between rice planted in the space station?

Want to come once, "Is the Heaven and Earth Fantasy linkage? This invitation must be closed!

China Space Station has sprout the seeds on the earth in space, so what is the difference between ground planting and space planting. In order to satisfy everyone's curiosity and stimulate young people's interest in space science experiments and scientific research. We launched the "A total of a species of the heavens and the earth -a plant with the astronauts with the astronauts" activity. The event invited students from 13 provinces and cities to plant anti -south mustard and rice with astronauts.

At the launching ceremony on September 9th, the space staff on the space station will be displayed on how the spacecraft on the space station cultivate to take care of plants, and invite famous host Wang Xuechun, researcher Zhang Wei of the Chinese Academy of Sciences Space Application Engineering and Technology Center, Researcher Le Jie, Institute of Botanicals of the Chinese Academy of Sciences, and the History of Natural Sciences of the Chinese Academy of Sciences Researcher Luo Guihuan, Cai Jie senior engineer of the Kunming Institute of Chinese Academy of Sciences, shared the story of plant cultivation and plant seeds with everyone with everyone.

For spoilers, we will also carry out the science popularization live broadcast of space themes on September 21 and September 29.

On September 21, the theme of "care for space plants" will be taken. Everyone has the opportunity to understand the planting units with experts and explore the physical and engineering knowledge of plant growth on the space station.

On September 29, the "plant -painted" popular science live broadcast will be carried out in the national botanical garden. By then, the plant hand -painted experts will explain how to perform plant scientific painting in combination with the characteristics of Arabia mustard and rice plant. Mimic

If you have any questions, you can post Weibo topic #如果 如果 如果 如果 如果 如果, ask questions you want to ask, or ask us in the background, we will collect regularly, and please ask experts to answer.

Is it "a whole" expectation, then remember to go to the appointment on time. On September 9th, lock the live broadcast room, let us plant "the future" with the astronauts!

At 15:30 pm on September 9th (Friday) on September 9 (Friday), at the Chinese Popular Science Expo Science Live, the Institute of Physics of the Chinese Academy of Science Guangming.com, Science Network, Bilibili, Weibo, Douyin, Kuaishou, Baidu App, Tencent Video, Sohu Video, Kouxiang Academic, Beijing Time and other media platforms were broadcast.
