One of the cotton seeds carried to the moon by China's Chang'e-4 probe is the first ever to sprout1 on the moon.
 
由嫦娥四号带上月球的棉花种子,其中一粒率先在月球上发芽。
 
 
After making the first-ever soft landing on the far side of the moon, China's Chang'e-4 mission pioneered the first mini biosphere2 experiment on the moon.
 
Professor Xie Gengxin, of Chongqing University and chief designer of the experiment, said a canister installed on the lander of the Chang'e-4 probe contained the seeds of cotton, rapeseed, potato, and arabidopsis, as well as eggs of the fruit fly and some yeast3, to form a simple mini biosphere.
 
Images sent by the probe showed that a cotton sprout had started to grow, though no other plants were found growing.
 
The cylinder4 canister, made from special aluminum5 alloy6 materials, is 198 mm tall, with a diameter of 173 mm and a weight of 2.6 kg. It also holds water, soil, air, two small cameras, and a heat control system, said Xie.
 
More than 170 pictures have been taken by the cameras and sent back to Earth, according to the team.
