Space Horticulture Lab
Machine-translated · View original
A lab that explores how plants respond to gravity and ultraviolet light in order to grow plants in space.

AboutAbout the lab
Growing plants in space.
The Space Horticulture Lab conducts research on growing plants in the space environment.
For people to stay on the Moon or Mars for long periods, technology to grow plants outside Earth as a source of oxygen and food is essential.
The lab studies how plants respond to environments very different from those on the ground, such as microgravity, space radiation, and ultraviolet light, and aims to develop cultivars useful for stable food production.
The results also form a foundation for technologies for sustainable food production on Earth.
Key terms
- Microgravity
- A state in which almost no gravity is felt, as inside a space station
- International Space Station
- A crewed experimental facility that orbits Earth and is jointly operated by multiple countries
- Cultivar
- A group within the same crop that is distinguished by differences in how it grows or its traits. New cultivars are created through breeding
