On January 3, 2019, the Chinese Chang’e-4 spacecraft made a successful soft landing on the far side of the moon in the Karman crater. In addition to all kinds of scientific instruments and meters, the robotic kit contained a special airtight container with plant seeds and insect eggs for an interesting biological experiment – the creation of a closed self-sufficient biosphere in extreme conditions of the Earth’s satellite. The first to grow cotton seeds. Unfortunately, cotton seed is the only one of all participants (there were six in all: cotton, potatoes, rape, yeast, fruit flies, Tal rezhovidka), who managed to sprout on the moon. However, according to the researchers, the moonlit night was too aggressive for every \The cotton sprout died because the temperature in the tank dropped to -52 ° C, although the container was supposed to support temperatures from 1 ° C to 30 ° C. Thus, the experiment, which lasted a little more than 212 hours, was completed. For their part, Chinese experts said that all organisms delivered to the Earth’s satellite will only slowly decompose within the sealed container in which they are located, that is, their effect on the lunar environment will be zero.
