BEIJING, May 21 -- At the China Space Station (CSS), the three taikonauts of the Shenzhou-21 crew — Zhang Lu, Wu Fei, and Zhang Hongzhang — have been in orbit for nearly 200 days. They remain in good physical and mental condition, and all tasks are progressing in an orderly and steady manner as planned.

Recently, the crew received nearly 6.2 tons of supplies delivered by the Tianzhou-10 cargo spacecraft. The cargo includes experimental payloads, experimental units and samples, consumables, and spare parts, which will support the on-orbit research of 41 scientific experiments.
