New Delhi, March 31: As humanity prepares for deeper space exploration, the significance of plants has increased. They are essential not just for aesthetics or oxygen but also for fresh food, vitamins, and mental well-being. To support this, NASA has developed a unique vegetable production system called ‘Veggie’ aboard the International Space Station (ISS).
Veggie is a small ‘space garden’ designed to grow plants in microgravity. This system, roughly the size of a carry-on bag, typically accommodates six plants at a time. Its primary goal is to study plant growth in microgravity and provide astronauts with fresh, nutritious food.
Each plant in Veggie is grown in a soil-based pillow filled with special fertilizers and nutrients. These pillows maintain the right balance of water, nutrients, and air for the roots. In the absence of gravity, water tends to form bubbles, making this balance challenging. LED lights above provide the necessary illumination, and since plants primarily utilize red and blue light, the Veggie chamber often glows a pinkish-red hue.
Various plant types have been successfully cultivated in Veggie, including three varieties of lettuce, Chinese cabbage, mizuna mustard, red Russian kale, and vibrant zinnia flowers. Some plants have been harvested and consumed by crew members, while others were sent back to Earth for study. Fresh fruits and vegetables are crucial not only for nutrition but also for the mental health of astronauts on long missions.
NASA believes that growing plants helps astronauts feel connected to Earth and reduces stress. In addition to Veggie, NASA has developed the Advanced Plant Habitat (APH), a more advanced and fully automated system. APH is equipped with over 180 sensors that continuously relay information to a team on Earth. Testing has already been conducted with dwarf wheat in APH, and in the future, NASA plans to grow tomatoes, peppers, berries, and other plants. These will not only provide nutrition but also offer some protection against radiation.
