Cottoning on: Chinese seed sprouts on moon

A small green shoot is growing on the moon in an out-of-this-world first after a cotton seed germinated on board a Chinese lunar lander, scientists said Tuesday. The sprout has emerged from a lattice-like structure inside a canister since the Chang'e-4 lander set down earlier this month, according to a series of photos released by the Advanced Technology Research Institute at Chongqing University. "This is the first time humans have done biological growth experiments on the lunar surface," said Xie Gengxin, who led the design of the experiment.
