Plants can metabolize carbon dioxide in the air to produce valuable oxygen, and can help control cabin humidity. [3] Growing plants in space may provide a psychological benefit to human spaceflight crews. [3] Usually the plants were part of studies or technical development to further develop space gardens or conduct science experiments. [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]
‘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 ...
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. [10]
The plant Arabidopsis thaliana is used in laboratories as a model organism to understand how genes control the growth and development of plant structures. [25] NASA predicts that space stations or space colonies will one day rely on plants for life support. [26] Scientific advances in genetic engineering led to developments in crops.
