The three Chinese astronauts from the Shenzhou-13 crewed space mission measured their height in a microgravity environment for the first time after traveling for more than two months aboard China's space station core module Tianhe. A camera captured Zhai Zhigang, Wang Yaping and Ye Guangfu as they attached fixators to the bulkhead of the space craft and tied ropes to them before taking their measurements. The height change of an astronaut in space is not only an indicator of the change in their external body shape, but also an important way of checking their bone condition.
