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.
Zinnia plant in bloom aboard an Earth orbiting space station. The growth of plants in outer space has elicited much scientific interest. [1] 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.

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]
‘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 ...
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]
Horticulture began with the domestication of plants 10,000–20,000 years ago and has since been deeply integrated into human history. [2] [3] The domestication of plants occurred independently within various civilizations across the globe.
Aeroponic cultivation involves growing plants in an air culture, allowing them to develop and grow naturally. [2] [failed verification] Aeroponic growth specifically refers to the process of growing plants in an air culture. An aeroponic system refers to the collection of hardware and components designed to support plant growth in an air culture.
One of the plants in this study is Bamboo palm (Chamaedorea seifrizii). The NASA Clean Air Study was a project led by the National Aeronautics and Space Administration in association with the Associated Landscape Contractors of America (ALCA) in 1989, to research ways to clean the air in sealed environments such as space stations.
