As China celebrates the 2026 Spring Festival, the crew of the Shenzhou-21 mission aboard the Tiangong space station has received a remarkable gift: a thriving harvest of tomatoes grown in orbit.
The “space vegetable garden” has once again demonstrated the potential for sustained plant life beyond Earth’s atmosphere.
In a video reported by China Media Group (CMG) on Wednesday, astronaut Zhang Hongzhang gave a tour of what he calls a “healing corner” of Tiangong, showing tomato plants exhibiting vigorous growth.
The aeroponic cultivation system nurturing these plants was developed by the China Astronaut Research and Training Center. It vaporizes water into a fine mist and uses a specially designed LED light spectrum to enhance energy efficiency, resulting in thriving space-grown tomatoes.
Delivered to the space station by the Tianzhou-9 cargo spacecraft in July 2025, the system’s primary mission is to validate technologies for cultivating plants in microgravity, with data informing future long-duration missions and bioregenerative life support systems.
Astronaut Wu Fei described the harvest as a treat for the crew: “Look at these tomatoes. They are so enticing, with a faint, fresh scent. Every time I pass by, I want to take a deep breath and enjoy the fragrance.”
Scientists on Earth are using the system to study space agriculture, including efficient cultivation methods, productivity of crops, atmospheric regeneration, and optimized care protocols for astronauts. Future plans include aeroponic trials of wheat, carrots, and medicinal plants, expanding the diversity of orbital crops.
For the crew, tending the garden provides a psychological boost amidst their demanding schedule. “To see such a vibrant splash of green in the vastness of space is incredibly healing,” said astronaut Zhang Lu.
Launched on Oct. 31, 2025, the Shenzhou-21 mission has now exceeded 100 days, with all scientific experiments, equipment maintenance, and health management progressing smoothly, according to the China Manned Space Agency.
