嫦娥4 completed the first human biological experiment of the moon, the first cotton grows on the moon

Zhongxin.com, Beijing, January 15 (Guo Chaokai) The reporter learned from the China National Space Administration's Lunar Exploration and Space Engineering Center on the 15th that the bio-copper load test carried by the No. 4 mission has been completed. From the pictures taken, the test was carried out. The seeds of cotton have signs of germination, which also marks the completion of the first biological experiment conducted by humans on the moon.

At present, Yutu No. 2 patrol has entered the state of doomsday, and the science test organisms carried out will slowly decompose in the bio-technical test load tank in the fully enclosed state, and will not affect the lunar environment.

The latest pictures show that the cotton shoots grow well. This is the first plant shoot that grows on the moon after experiencing severe environmental changes such as high vacuum, wide temperature difference and strong radiation. It is the first time for humans. The biological growth cultivation experiment of the lunar surface.

It is understood that the bio-science test conducted on the moon was designed by Chongqing University. Six species of cotton, rapeseed, potatoes, Arabidopsis, yeast and fruit flies were selected as samples to bring their seeds and eggs to the sample. Cultivate on the moon. A simple micro-ecosystem is formed between the six organisms, all placed in a sealed bioscience test load tank. During the ground assembly and capping process, all bio-loading operations are performed in a clean bench in a strictly sterile environment to ensure no biological contamination throughout the process.

The screening of biological species for this popular science experiment has very stringent requirements. Due to the limited load size, the animals and plants inside can not occupy too much space, so the first condition is “small size”. At the same time, it must be able to adapt to the extreme conditions of the lunar surface, requiring animals and plants to withstand high temperatures, freeze resistance, and to resist radiation and anti-interference.
