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.
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]
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 Moon Tree Foundation is an organization run by Roosa's daughter, Rosemary, which seeks to plant Moon trees in regions around the world. The foundation sponsors and hosts ceremonies to plant new trees, with seeds produced by the original generation of trees that grew from the seeds carried by Roosa in 1971.
A Kalanchoe species was one of the first plants to be sent into space, sent on a resupply to the Soviet Salyut 1 space station in 1979. [4] The majority of kalanchoes require around 6–8 hours of sunlight a day; a few cannot tolerate this, and survive with bright, indirect sunlight to bright shade. [citation needed]
NASA life support GAP technology with untreated beans (left tube) and biocontrol treated beans (right tube) returned from the Mir space station aboard the space shuttle – September 1997. Plants had their first encounters with Earth's orbit back in 1960 during two separate missions, namely Sputnik 4 and Discoverer 17 (for a comprehensive ...
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.
