China Harvests First Space-Grown Rice Crop on Tiangong Station
Astronauts on a space station grew rice in space and picked the first batch.
Growing food in space could help astronauts on long trips to the Moon or Mars.
If they can grow their own food, they will not need to carry so much from Earth.
The rice seeds traveled to the Tiangong space station on a spaceship called Shenzhou-23.
Three astronauts took care of the rice for more than two months before harvesting it.
This builds on an earlier experiment in 2022, when rice was grown in space for a full life cycle for the first time.
Now scientists want to see if rice that grew in space can produce more rice in space.
They are testing two ways of growing it, including letting new shoots grow from the roots of the first plants.
Some plant stems and leaves will be kept cold and brought back to Earth for scientists to study.
This research will help us learn how to farm beyond Earth one day.
Chinese astronauts aboard the Tiangong space station harvested the first batch of rice grown in orbit on the Shenzhou-23 mission.
Astronauts Zhu Yangzhu, Zhang Zhiyuan, and Lai Ka-ying collected the rice samples after more than two months of cultivation.
The harvest builds on China's 2022 world-first full life-cycle rice experiment, in which six seeds spent 120 days in orbit and produced 59 space-grown seeds.
Scientists are comparing two types of japonica rice and two growing methods — seed-to-seed reproduction and ratooning — aiming to grow two consecutive generations in orbit.
Stems and leaves preserved at low temperatures will be returned to Earth to improve space farming for future Moon and Mars missions.
- Who
- Three Chinese astronauts — Zhu Yangzhu, Zhang Zhiyuan, and Lai Ka-ying — aboard the Tiangong space station.
