Chinese planting of the moon boasts of its promise –

The latest Chinese space biology experiment, in which cotton seeds grow on the distant side of the moon aboard its Changsha 4 moon, is a "significant leap" in life-saving technologies for the future living space of people.

A probe container that forms a mini-sphere for cotton, rapeseed, potato and arabidopsis seed, as well as fruit fly eggs and some yeast has completed its work as planned, and the data gathered will be "invaluable to improve experimentation and eventually make the moon habitable for the people, "said See Gengsin, chief designer on Friday.

With the experiment and earlier related efforts, China is leading in the field of bioregenerative life support and space farming technologies that are critical to the long-term research of human space, according to Marshall Porterfield, who is the director of the Space Life Division NASA and Physics from 2012 to 2016.

The main differences in the experiment carried out on the mission of Changes 4 and those of others, including the International Space Station (ISS), are the automation and integration of bio-research capabilities in the lunar passenger, said Porterfield, now professor of agriculture and biological engineering at Purdue University.

"This puts the experiment out of the planet's radiation protection," he said, adding that deep cosmic radiation is the main obstacle to the study of human Mars, and the ISC's research does not currently expose experiments on the radiation environment in deep space.

Porterfield, who has been involved in space biology for more than 25 years, said that the Chinese surface lunar experiment earns life in a harsh environment and builds knowledge and experience in understanding life in deep space.

"When I was at NASA, we had the opportunity to develop these kinds of experiments, but we did not have any budget or resources." China is doing this important job that will greatly contribute to the future of living space, "he said.

NASA, the National Aviation and Space Administration, has a long history of bioregenerative life support and a controlled environment in the 80's and 90's.

Similarly, the former Soviet Union and later Russia invested and pursued such biotech platforms, starting with Saluto's first space stations and continuing through Peace, according to Porterfield.

Porterfield said that during his tenure as a director of a NASA division, he and his colleagues developed and completed experiments for vegetarians testing a plant system in the vicinity of space, and a one-year mission, a research project on the ISS board. investigates the health effects of long-term space flights.

"Based on my work experience and leadership in this field, I am very excited about the achievements of Chinese space science," he said.

While these biotech platforms are considered to be absolutely necessary and necessary for human resource research in the solar system, NASA and Russia have ceased their programs and currently lack the capacity and expertise to pursue bioregenerative lifesaving and agricultural technologies. ,

China is leading in this area now and has invested considerable resources in developing its own biotech test bed, he said.

"These recent experiments are a significant leap in pursuing modern life-saving technologies for prolonged human research," Porterfield said.

Briony Horgan, assistant professor of Earth, Atmospheric and Planetary Sciences at Purdue University, said sustained gardening and eventually agriculture in space would be "absolutely critical" to maintaining a permanent human presence on the Moon or Mars.

"Experiments such as Chang's biological experiments are an important step toward understanding how we can process in the unique conditions of space, including low or low gravity and sterile environment," said Horgan to China Daily.

The closest terrestrial vegetation to the moon was in 1971 when Apollo 14 astronaut Stewart Rose brought hundreds of tree seeds in orbit around the moon with it, reported on January 15th.
