"Grain Planting Grain" and "Planting vegetables" at the space station is a big topic

Reporter Fan Wei

"Global Times" reporter learned from the introduction of the phase progress of the manned space engineering space application and space stations on the 29th, and learned that as of now, the status of scientific experimental facilities such as the life ecological experimental cabinet deployed on the experimental compartment on the experimental compartment is in good condition. The work is stable, and the scientific experiment project launched with the cabin is carried out in the planning. Experimental units containing experimental samples of southern mustard seeds and rice seeds have been installed from a space staff to the life ecological ecological experiment module that asked the sky experimental cabin. At present, plants have germinated and growing.

Highly stalk rice has grown to 30 cm

In the past ten years, with returning to the moon, landing in Mars, and establishing a moon or Mars base, it has become an important goal of human space exploration. Taking the food production of food for long -term life in space, it is studied as a research object. How to cultivate or cultivate plants, explore the conditions and technical channels required for efficient production in the space environment, and finally achieve the goal of human long -term space exploration of human beings.

According to a reporter from the Global Times, on July 28, experimental units containing experimental samples and rice seeds were installed in the life and ecological experiment module of the interview compartment from the astronaut to The experiment was launched on July 29. At present, the seeds of Naman mustard and rice have been successfully launched. Multi-mustard seedlings have grown multiple leaves, high-straw rice seedlings have grown to about 30 cm, and low-straw rice is also 5-6 cm high. The experiments of Arabia and rice in the whole life cycle from the seeds to the seeds of the nanda and rice will be completed. During the experiment, the astronauts collected samples and frozen preservation, and finally returned to the ground with the astronauts to analyze.

Researchers at the Molecular Outstanding Center of the Chinese Academy of Sciences, Zheng Huiqiong, an experiment project leader of the "Molecular Mechanism of Higher Plants Flowing and Regulatory Molecule of Higher Plants under Micro Gravity Conditions", said in an interview with the Global Times on the 29th that the seeds of crops are both food and reproduction of breeding. The carrier of the next generation. With the deepening of the development of people's deep space detection, such as landing in Mars, in order to truly solve the problem of food guarantee for human long -term space exploration, it is impossible to rely on carried grain from the earth to meet the long -term space life and work needs of aerospace members. It is necessary to solve the problem of food production in space. Because the life of the earth cannot survive without protection under the conditions of severe space environment, the production of space crops in the future must be carried out in a completely closed artificial environment, and the planting space and energy supply must be very scarce. Therefore, the crops grown in space must meet the requirements of high -yield, high -quality, high production efficiency and low energy consumption.

Zheng Huiqiong introduced that the research on crop experimenting at the Chinese Space Station this time is expected to complete the training experiments from "seeds to seeds" full life cycle under the condition of spatial micro -gravity conditions in the world and obtain key environmental parameters of rice training. In order to further analyze the impact of space micro -gravity on rice growth and molecular basis, the use of rice to provide important theoretical guidance with spatial grain production.

Subsequent space experiments will be more "high -energy"

As of now, three astronauts in Shenzhou 14 have worked for more than 80 days. There will be a big task of the three astronauts multiplication, that is, waiting for the arrival of the Mengtian experimental compartment. According to a reporter from the Global Times, the second experimental cabin section of the Chinese space station — Mengtian Experimental Cels have completed all development work before the factory earlier this month, shipped to Wenchang Aerospace launches, and will be launched in October this year. After the launch is successful, my country's National Space Lab will be completed. Later, Tianzhou 5 freight ships and Shenzhou 15 manned spacecraft will be launched. After the dealer with Shenzhou 14, it will stay in the rails for 6 months.

At the introduction meeting held on the 29th, Zhao Liping, a researcher at the Chinese Academy of Sciences Space Application Center and the manned space engineering space application system, introduced the main working items of the subsequent space application system. Zhao Liping said that between August and October, the manned space engineering space application system will conduct a life ecological experimental cabinet tracking experiment, biotechnology experimental cabinet, life ecological experimental cabinet regular module inspection, and gravity science experimental cabinet, science science Glove boxes and low -temperature storage cabinets are tested on orbit. During the mission of Shenzhou 15, energy particles detectors and plasma in situ imaging detectors will be assembled, self -test, out -of -class installation, rail testing, and work on orbit.

After the completion of the China Space Station, my country will also choose to launch the sky -to -space telescope, fly with the space station for a long time, carry out sky -to -day observations, and stop the space station for supply and maintenance and upgrade in the short term.

Zhang Wei, a researcher at the Chinese Academy of Sciences Space Application Center and the director of the Application Development Center, previously stated in an interview with the Global Times and other media that the sky patrol space telescope was 2 meters caliber, the imaging quality was comparable to Hubble, and the field of view was nearly 300 times. The field of space astronomy and earth science will use astronomical observation facilities such as celestial lighting telescope, high -energy cosmic radiation detection facilities to carry out dark matter and dark energy, the formation and evolution of cosmic structure, the origin and evolution of galaxy, the formation and evolution of large quality black holes, the origin of the cosmic line origin As well as research on the exploration of ex -planet detection of the solar system; focus on the major issues of global climate change, carbon peak and carbon neutralization, etc., to carry out research and verification of new technologies and new systems on local observation of local observation.

In addition, the field of space new technology and application will also develop space robots and autonomous systems, space intelligent manufacturing and construction, tiny satellite formations and applications, ground moon space light communication and independent navigation technology, core components and ministry components and other space new technologies tests Essence Official announcement of the latest progress of the experimental compartment

At the introduction meeting held on the 29th, Zhao Liping, a researcher at the Chinese Academy of Sciences Space Application Center and the manned space engineering space application system, said that after the launch of the test cabin was launched, the three astronauts were in On July 28, the life ecological experimental cabinet universal biological training module unlock, status settings, radiation measurement module and plant training unit installation.

The astronauts also completed the unlocking and assembly of gravity science experimental cabinets, scientific glove boxes, low -temperature storage devices, and biotechnology experimental cabinets on August 8 and August 12, respectively. "After the assembly is completed, the gravity scientific experimental cabinet, scientific glove box, and low -temperature storage device have carried out the established on -orbit test content. Through downward remote test data and engineering data judgment, the relevant scientific experimental cabinets and the scientific experiment system work normally, the loading status is good ","

On July 28, after the installation of the scientific experimental unit of the three astronauts completed the ecological experimental cabinet scientific experimental unit in the general biological training experimental module, they began to injected the experimental samples and rice seeds with the experimental sample with the Chinese space station. In the rail experiment, under normal temperature, humidity, and light control, ground personnel analyzed and judged through the downlink image data, and the growth status of rice and nanda mustard seeds grew normally after germination.

Zhao Liping said that after the launch of the Tiangan experimental cabin was launched, the space environment guarantee system was divided into 24 hours to monitor the changes in the space environment. At present, a total of 549 spatial environment forecast products are released. According to the current space environment monitoring data analysis, the current level of solar activity is extremely low to low, and geomagnetic activities are mainly calm to micro -disturbances, which will help the space station on orbit work.
