China achieves orbital cultivation of 14 plant species
China has successfully cultivated more than 20 varieties across 14 plant species in orbit, marking a significant milestone for agricultural production on the Tiangong space station. This achievement was announced by the China Astronaut Center during an aerospace medical engineering conference in Tianjin.
Astronaut Zhang Hongzhang shared visual evidence of the “space garden,” which includes crops such as lettuce, carrots, sunflowers, potatoes, and wheat. The research focuses on controlled ecological life support technology, which aims to create a closed ecosystem capable of regenerating water, air, and food in situ. This technology is designed to reduce reliance on Earth-based supplies during long-term space missions.
Currently, two types of cultivation units are operational: substrate-based and aeroponic systems. Experts noted that wheat has already completed a full growth cycle from seed to maturity, with a second round of planting currently underway. These advancements serve as a foundation for future large-scale space farming and potential “lunar gardens” as part of China’s lunar exploration programs.
