NASA plans to grow plants in space to help feed astronauts and to provide psychological benefits for long-term space flight. [7] In 2017, aboard ISS in one plant growth device, the 5th crop of Chinese cabbage ( Brassica rapa ) from it included an allotment for crew consumption, while the rest was saved for study. [ 8 ]
Cabbage growing in a Veggie unit [1]. The Vegetable Production System (Veggie) is a plant growth system developed and used by NASA in space environments. The purpose of Veggie is to provide a self-sufficient and sustainable food source for astronauts as well as a means of recreation and relaxation through therapeutic gardening. [2]
Essentially, the space farm turns the spaceship into an artificial ecosystem with a hydrological cycle and nutrient recycling. [4] [5] In addition to maintaining a shelf-life and reducing total mass, the ability to grow food in space would help reduce the vitamin gap in astronaut's diets and provide fresh food with improved taste and texture.
The study of plant response in space environments is another subject of astrobotany research. In space, plants encounter unique environmental stressors not found on Earth including microgravity, ionizing radiation, and oxidative stress. [23] Experiments have shown that these stressors cause genetic alterations in plant metabolism pathways.
‘The ability to grow plants in space for fresh food and an improved crew living experience is important for future long-duration missions,’ Nasa says Space tomatoes head back to Earth Skip to ...
Wastewater treatment makes use of plants, particularly aquatic, to process the wastewater. It has been shown that the more waste is treated by the aquatic plants (or, more specifically, their root systems), the larger the aquatic plants grow. In tests, such as those done in the BioHome, the plants also made viable compost as a growth medium for ...
NASA space foods are packaged in retort pouches [13] or employ freeze drying. [11] They are also packaged in sealed containers which fit into trays to keep them in place. The trays include straps on the underside, allowing astronauts to attach the tray to an anchor point such as their legs or a wall surface and include clips for retaining a ...
The Moon Tree Foundation is an organization run by Roosa's daughter, Rosemary, which seeks to plant Moon trees in regions around the world.
