The germination of those cotton seeds mark the very first seeds to germinate on the moon's far side.
The lead scientist for China's lunar project revealed on Tuesday that USA space scientists had asked permission to use China's Chang'e 4 spacecraft and relay satellite to help them plan an American mission to the far side of the moon.
Liu Hanlong, who is leading the experiment, said Tuesday that potato seeds and rapeseeds also had sprouted, according to the South China Morning Post. A flowering plant called Arabidopsis, yeast and fruit fly eggs were also part of the organic experiment. The plants produced oxygen and food by photosynthesis and sustained the fruit flies.
Skygazers are set to be treated to a total lunar eclipse this weekend, on top of a "super blood wolf moon".
"In the past, we were always rushing to catch up to the advanced global standards" in space, said Wu Weiren, the chief designer of China's lunar exploration project.
It is hoped the experiment will pave the way for long-term space exploration and provide astronauts with the means to grown their own crops, à la Damon.
However, plants have successfully been grown on the global Space Station (ISS). The image above, taken on January 7, shows a sprouting of a cotton seed.
The Chang'e-4 lander, which carries the 3 kg biosphere, imaged by the Yutu-2 rover on the far side of the Moon in January 2019.
Xie said the experiment would allow scientists to learn how plants can grow in the "low gravity, strong radiation and natural lighting conditions of the Moon", according to the university. Many of these seeds were later planted back on Earth, becoming "Moon Trees".
Wu Weiren, chief scientist of China's lunar programme, told reporters with state broadcaster CCTV that Nasa scientists had made the request at an global conference a few years ago.
According to Wu, the Chang'e 6 mission will be created to bring samples back from the moon's south polar region.
The journey took more than 20 days, and scientists at the China National Space Administration spent two months doing final checks before sending it into space.
