Chinese astronauts aboard the China Space Station have achieved a breakthrough in extraterrestrial agriculture, with tomato plants flourishing under their care in 2026. The Shenzhou-21 mission crew recently reported vigorous growth in the orbital greenhouse, utilizing an aeroponic cultivation system that nourishes roots through mist rather than soil.
Advanced LED light spectra guide the vines' development, mimicking Earth's natural cycles to optimize photosynthesis. This innovation marks a critical step toward sustainable long-term space missions, with researchers noting the experiment's implications for future lunar bases and interplanetary travel.
While previous space farming attempts focused on leafy greens, this year's tomato cultivation demonstrates progress in growing complex fruiting plants. Scientists on the Chinese mainland emphasize the project's potential to support crew nutrition and psychological well-being during extended orbital stays.
