The team behind a pioneering biological experiment sent to the lunar far side has released an image showing two green leaves grown on the moon. From a report: The experiment began shortly after China’s Chang’e-4 spacecraft made the first ever landing on the far side of the moon, on 3 January this year. Cotton, arabidopsis and potato seeds, and fruit-fly eggs and yeast were all aboard the 2.6-kilogram mini biosphere, but only the cotton produced positive results. Image processing has now shown that two cotton leaves had grown — rather than just one as initially thought — in what was the first biological growth experiment on the moon. All the species died with the onset of the first lunar night, with no power to protect the canister from temperatures that reached as low as minus 190 degrees Celsius. The cotton leaves were dead within one lunar daytime, or around 14 and a half Earth days. The experiment continued until May, however, in order to test the longevity of the apparatus. The Chang’e-4 lander and rover meanwhile have just started their tenth lunar daytime in Von Karman crater.
