A video clip released on Oct. 20 shows a silkworm squirming on the fingertip of Jing Haipeng, one of the Chinese astronauts on the Tiangong-2 space lab.

After China's Shenzhou-11 spacecraft docked with the Tiangong-2 space lab, a total of six silkworms were brought into the space lab for experiments. In the first experiment, people can observe the silkworms’ development under microgravity, comparing it with the development of silkworms on Earth. The silkworms on the spacecraft were specially cultivated by scientists.
