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] Veggie was designed in conjunction with ORBITEC and went operational aboard the International Space Station in 2014, with another Veggie module added to the ISS in 2017. [3]
The ‘Veggie’ vegetable production system was deployed to the ISS as an applied research platform for food production in space.. Among the goals of this project are to learn about how plants grow in a micro-gravity environment and to learn about how plants can efficiently be grown for crew use in space. [2] Veggie was designed to be low maintenance, using low power and having a low launch mass. Thus, Veggie provides a minorly regulated environment with minimal control over the atmosphere and temperature of the module. The successor to the Veggie project is the Advanced Plant Habitat (APH), which was delivered to the International Space Station in 2017. [4] [5]
In 2016 the Veggie-3 experiments (VEG-03 A,B,C,D) grew "outredgeous" red romaine lettuce, Tokyo Bekana Chinese cabbage, Mizuna mustard and Waldmann's Green lettuce . [3] [6]
A Veggie module weighs less than 8 kg (18 lb) and uses 90 watts. [7] It consists of three parts: a lighting system, a bellows enclosure, and a reservoir. [8] The lighting system regulates the amount and intensity of light plants receive, the bellows enclosure keeps the environment inside the unit separate from its surroundings, and the reservoir connects to plant pillows where the seeds grow.
Veggie's lighting system consists of three different types of coloreds LEDs: red, blue, and green. Each color corresponds to a different light intensity that the plants will receive. [2] Although the lighting system can be reconfigured, the following table shows the default settings and their corresponding intensities in micromoles per second per square meter. [2]
Setting | Red | Blue | Green |
---|---|---|---|
Low | 120±10% | 30±10% | - |
Medium | 240±10% | 60±10% | - |
High | 360±10% | 90±10% | - |
On | - | - | 30±5% |
Potential | 550 | 150 | 100 |
In addition to this lighting system, Veggie also uses opaque bellows to obstruct external sources of light. [2]
The bellows enclosure controls the flow and pressure of air within the container. The bellows are made from a fluorinated polymer and connected to the lighting system at its top and a baseplate at its bottom. Power and cooling is provided to the hardware that powers the bellows by ExPRESS Racks. [2] Although the bellows regulate air flow and air pressure, temperature and humidity are left controlled by the surrounding environment of the Veggie module. [8]
The reservoir of the Veggie module contains and provides water to the plant pillows in which plants grow. The plant pillows contain all other material such as fertilizer and seeds for the plant to grow. Seeds are oriented inside the sticky plant pillow so that their roots will grow downwards into the substrate provided by the plant pillow and that their stems will grow upwards outside of the plant pillow. [9]
The following plants have been grown using the Vegetable Production System:
In 2010, Desert Research and Technology Studies (Desert RATS) performed operational tests of the Vegetable Production System with lettuce. The three lettuce cultivars that were initially planted yielded positive results, growing and being consumed in 14 days. The Desert RATS team reported uniformly positive psychological results from the test crew. [15] No substantial information has been released as of yet on the differences between the nutritional values of space-grown plants and earth-grown plants.
As of August 2015, the Veggie system has succeeded in growing edible plants on the ISS. [9] Further, NASA has announced plans to launch a more advanced plant growth system named Advanced Plant Habitat in 2017. [2] No results have been recorded on the psychological benefits of the Veggie system in space.
The International Space Station (ISS) is a large space station assembled and maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA, Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ISS is the largest space station ever built. Its primary purpose is to perform microgravity and space environment experiments.
Lettuce is an annual plant of the family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, celtuce, is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. As of 2021, world production of lettuce and chicory was 27 million tonnes, 53 percent of which came from China.
Cauliflower is one of several vegetables cultivated from the species Brassica oleracea in the genus Brassica, which is in the Brassicaceae family.
The Destiny module, also known as the U.S. Lab, is the primary operating facility for U.S. research payloads aboard the International Space Station (ISS). It was berthed to the Unity module and activated over a period of five days in February, 2001. Destiny is NASA's first permanent operating orbital research station since Skylab was vacated in February 1974.
Aeroponics is the process of cultivating plants in an air or mist environment, eliminating the need for soil or an aggregate medium. The term "aeroponic" originates from the ancient Greek: aer (air) and ponos. It falls under the category of hydroponics, as water is employed in aeroponics to deliver nutrients to the plants.
Mizuna, kyouna (京菜), Japanese mustard greens, or spider mustard, is a cultivar of Brassica rapa var. niposinica.
Space food is a type of food product created and processed for consumption by astronauts during missions to outer space. Such food has specific requirements to provide a balanced diet and adequate nutrition for individuals working in space while being easy and safe to store, prepare and consume in the machinery-filled weightless environments of crewed spacecraft. Space food is commonly freeze-dried to minimize weight and ensure long shelf life.
The Space Station Processing Facility (SSPF) is a three-story industrial building at Kennedy Space Center for the manufacture and processing of flight hardware, modules, structural components and solar arrays of the International Space Station, and future space stations and commercial spacecraft. It was built in 1992 at the space complex's industrial area, just east of the Operations and Checkout Building.
Astrobotany is an applied sub-discipline of botany that is the study of plants in space environments. It is a branch of astrobiology and botany.
Napa cabbage is a type of Chinese cabbage originating near the Beijing region of China that is widely used in East Asian cuisine. Since the 20th century, it has also become a widespread crop in Europe, the Americas, and Australia. In much of the world, it is referred to as "Chinese cabbage". In Australia, it is sometimes referred to as "wombok".
TROPI, or "Analysis of a Novel Sensory Mechanism in Root Phototropism", is an experiment on the International Space Station (ISS) to investigate the growth and development of plant seedlings under various gravity and lighting combinations. It was launched on Space Shuttle Endeavour during the STS-130 mission and was performed on the ISS during Expedition 22. Frozen plant samples from the TROPI experiment were returned on the landing of the STS-131 mission on Space Shuttle Discovery.
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit. The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology. The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector.
Expedition 39 was the 39th expedition to the International Space Station. It marked the first time the ISS had been under command of a Japanese astronaut, space veteran Koichi Wakata. After Expedition 21 in 2009 and Expedition 35 in 2013, it was only the third time an ISS crew was led by neither a NASA nor an RSA crew member.
SpaceX CRS-3, also known as SpX-3, was a Commercial Resupply Service mission to the International Space Station (ISS), contracted to NASA, which was launched on 18 April 2014. It was the fifth flight for SpaceX's uncrewed Dragon cargo spacecraft and the third SpaceX operational mission contracted to NASA under a Commercial Resupply Services (CRS-1) contract.
Space farming refers to the cultivation of crops for food and other materials in space or on off-Earth celestial objects – equivalent to agriculture on Moon.
The growth of plants in outer space has elicited much scientific interest. In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens. In the context of human spaceflight, they can be consumed as food and provide a refreshing atmosphere. Plants can metabolize carbon dioxide in the air to produce valuable oxygen, and can help control cabin humidity. Growing plants in space may provide a psychological benefit to human spaceflight crews. Usually the plants were part of studies or technical development to further develop space gardens or conduct science experiments. To date plants taken into space have had mostly scientific interest, with only limited contributions to the functionality of the spacecraft, however the Apollo Moon tree project was more or less forestry inspired mission and the trees are part of a country's bicentennial celebration.

A space habitat in a basic sense is any facility providing shelter and fulfilling habitational purposes in outer space. It is not to be confused with an extended space settlement, an arrangement of or infrastructure for multiple habitation facilities, in the sense of a space settlement. Space stations or theoretical extraterrestrial stations, such as a Moonbase or Mars habitat, include or are basic space habitats.
