The Chang'e 4 lander contains seeds to grow plants on the Moon. The Moon has non-sustainable life conditions. Among those are the lack of water, atmosphere, the varying extreme temperatures, the low gravity, the solar radiations, etc.
However at least one cotton plant has germed and is in the process of growing.
How did the CNSA engineers have the plants germ then grow on the Moon? And are the plants supposed to die of natural death or will the harsh conditions kill them, if such, which one first?
