Back in January, China became the first country to grow a plant on the Moon — a single cotton seedling sprouted before dying in
the harsh cold of the lunar night.
But newly-released images reveal that the cotton plant fared a little bit better in its sealed-off biome than previously believ
ed. The seedling grew two green leaves before it died, according to IEEE Spectrum, instead of just one as previously reported.
While the difference between growing one and two cotton leaves is fairly inconsequential, the images are a fascinating glimpse
into China’s attempts to study how the lunar environment affects life.
The Chinese National Space Administration also tried to grow potatoes and yeast, and to hatch fruitfly eggs, in the tiny canist
er that contained the cotton plant.
None of them survived, but IEEE Spectrum reports that the experiment continued through May anyway to determine how well the pre
ssurized biome canister held up over time.
Even so, the scientists had more ambitious plans — they wanted to send a tortoise to the Moon so they could learn how animals a
re affected by lunar gravity, potentially as a preliminary step toward establishing a Moon colony.
Thankfully — for the tortoise, at least — the Chang’e-4 probe couldn’t support that much extra weight, so the critter stayed ho
me on Earth.
“Even though it is very meaningful to choose tortoise, the oxygen inside the payload can only be used for about 20 days for tur
tles,ö project leader Xie Gengxin of Chongqing University told IEEE Spectrum.
