These include experiments with silkworm cocoon hatching, moss rehydration and oxygen generation using plants in the low lunar gravity.
Other projects on the shortlist include shielding from cosmic rays, and studies on the influence of the lunar gravity environment on the division of embryonic stem cells, and other biology experiments involving plants, insects, fungi and bacteria.
A similar contest has been opened to send a popular science experiment on China's near-Earth asteroid sample return mission, which plans to launch to small asteroid Kamo'oalewa in 2024 and also visit a main belt comet after delivering samples to Earth. .Shortlisted experiments for this mission include using seismic waves to investigate the interior of the target asteroid and various impact, landing and sampling experiments.China's ongoing Chang'e 4 mission on the far side of the moon also carried an experiment from a university.
