NASA has launched a new chapter in space agriculture as Crew-11 astronauts carried out the latest VEG-03 experiments aboard the International Space Station (ISS), which began on August 1, 2025.
The mission features specially prepared seed pillows designed for cultivating crops in microgravity.
Astronauts can select plants from a seed library containing Wasabi mustard greens, Red Russian kale, and Dragoon lettuce, offering both nutritional and psychological benefits for crew members during long missions.
The plants will grow inside Veggie, a chamber about the size of a carry-on suitcase.
This system uses red, blue, and green LED lights to supply the spectrum needed for plant growth, while clear flexible bellows expand to create a semi-controlled environment for maturing plants.
Seeds are embedded in thin strips placed within fabric pillows filled with a clay-based medium and slow-release fertilizer.
The clay, similar to the material used on baseball fields, allows for even distribution of water and air around the roots in space’s weightless environment.
Astronauts will closely monitor the plants, water them as necessary, and document progress through photographs.
Once harvested, some produce will be eaten fresh on the ISS, while other samples will be frozen and sent back to Earth for analysis to determine nutritional value and safety.
NASA considers this work essential for future deep-space exploration, where fresh food will be vital for astronauts traveling to the Moon, Mars, and beyond.
The ability to grow a variety of crops will enhance dietary options and give crew members more autonomy in choosing what they eat.
Beyond supporting space exploration, these innovations could also have significant benefits for Earth.
The techniques developed for growing crops in the extreme conditions of space could be adapted to improve indoor agriculture and controlled-environment farming on Earth.
This could particularly help in regions with poor soil, limited water, or harsh climates.
NASA highlights that similar systems could also be incorporated into horticultural therapy programs, allowing elderly or disabled individuals to engage in gardening in a more accessible way.
The Biological and Physical Sciences Division of NASA leads these studies to better understand biological and physical processes in extreme environments, aiming to generate scientific knowledge that enables humans to travel farther and remain in space longer, while simultaneously contributing to advancements on Earth.
The VEG-03 MNO mission builds on previous experiments in space farming and is a step toward achieving sustainable food production during long-duration missions, bringing humanity closer to the reality of living and working in deep space for extended periods.
