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. [1]
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.
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.
They found plant life — mostly mosses — had increased in this harsh environment more than 10-fold over the past four decades, according to the study by scientists at the universities of Exeter ...
Ashley Cooper/Getty Figuring out how to feed people in space is a major part of a larger effort to demonstrate the viability of long-term human habitation of extraterrestrial environments. On May ...
In the late 1980s, NASA conducted a study on ways to improve air quality in sealed environments (such as space stations—go figure). It found that plants enhance indoor air quality by absorbing ...
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]
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]
