In the 2010s there was an increased desire for long-term space missions, which led to desire for space-based plant production as food for astronauts. [10] An example of this is vegetable production on the International Space Station in Earth orbit. [10]
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.
However, plants experience normal growth given that directional light is provided. [10] Normal growth is classified as opposite root and shoot growth direction. This being said, many plants grown in a space flight environment have been significantly smaller than those grown on Earth's surface and grew at a slower rate. [10]
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]
Early space-flight had travelers either ejecting their wastes into space or storing it for a return trip. CELSS studied means of breaking down human wastes and, if possible, integrating the processed products back into the ecology. For instance, urine was processed into water, which was safe for use in toilets and watering plants.
Space manufacturing or In-space manufacturing (ISM in short) is the fabrication, assembly or integration of tangible goods beyond Earth's atmosphere (or more generally, outside a planetary atmosphere), involving the transformation of raw or recycled materials into components, products, or infrastructure in space, [3] where the manufacturing ...
Another source estimated over 100 startups in the space of 2018. [23] In Asia, adoption of indoor agriculture has been driven by consumer demand for quality. [24] The Recirculating Farms Coalition is a US trade organization for hydroponic farmers. [25] A 2020 survey of indoor plant farming in the U.S. [26] found that indoor production was: 26% ...
ISRU reverse water gas shift testbed (NASA KSC) ISRU Pilot Excavator – A NASA project. In space exploration, in situ resource utilization (ISRU) is the practice of collection, processing, storing and use of materials found or manufactured on other astronomical objects (the Moon, Mars, asteroids, etc.) that replace materials that would otherwise be brought from Earth.
