report from this newspaper (china youth daily·china youth daily reporter zhang miao) lu congmin, chief designer of the space application system of china's manned space project and deputy director of the space application center of the chinese academy of sciences, was at the china manned space station 2024 space science conference held on september 25 it was revealed at the annual conference on science and application that since the construction of china's manned space station, the space application system has carried out more than a hundred scientific experiments and application tests in orbit, and achieved important research progress including many firsts.
the china manned space station 2024 space science and application academic annual conference is the first academic conference for focused exchanges in various disciplines in the field of space science and application of china's manned space engineering. lu congmin introduced when delivering a keynote report on "progress in science and application of manned space station", since the construction of the space station, the uplink load and experimental samples of the space application system have been nearly 1.8 tons. nearly 100 samples have been returned in 6 batches with the manned spacecraft, weighing nearly 100 kilograms. the samples mainly include metal and alloy materials, functional crystals, and non-metal composite materials. and other material samples, as well as life experiment samples such as cells, proteins, and plants.
at present, the scientific experiments and application experiments of the china space station continue to produce phased research results: in the field of space life, it has revealed the mechanism of microgravity affecting the formation and changes of osteoblasts, and discovered more than 10 potentially important targets related to bone loss, which are expected to be applied drug intervention for osteoporosis; china built the zebrafish-hornwort binary ecosystem in orbit for the first time, and it operated stably in orbit for more than 40 days, achieving china's breakthrough in cultivating vertebrates in space; completing the "from seed to seed" process of rice in space for the first time cultivated and completed the space regeneration rice culture throughout the life cycle, discovered a new set of molecular regulation of microgravity-responsive flowering pathways, and carried out extravehicular exposure experiments on 16 samples including nematodes, microorganisms, rice seeds, and biological macromolecules.
in the field of space materials, a series of progress and important scientific discoveries with international influence have been made in the solidification mechanism of metals and alloys, functional crystals, and exposure of extravehicular materials. a variety of functional crystal materials with potential application value have been developed, and their performance is generally better than that on the ground. .
in the field of microgravity fluids, the complete characteristics of surface tension-driven flow in fully managed and semi-managed tank fluid structures have been obtained, providing scientific and technical support for the widespread application of plate-type tanks in my country's spacecraft. in the field of basic microgravity physics, all-optical traps are used to prepare bose-einstein condensates (bec) in orbit.
ding chibiao, vice president of the chinese academy of sciences, pointed out in the video speech that the manned space station, as the national space laboratory, has brought unprecedented development opportunities to china’s space science and applied research. it is necessary to unite the superior scientific and technological forces at home and abroad, give full play to the advantages of the national space laboratory, and focus on major issues. scientific and technological issues and major national needs, condense scientific goals, formulate scientific plans, and produce influential scientific results as soon as possible.
the academic annual conference has 6 disciplines, more than 20 academic sub-forums, and announced the list of the new scientific working committee in the professional field of china's manned space engineering space application system.
