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]
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 study researchers showed that the arabidopsis plant – thale cress – can successfully grow in soil collected during the Apollo missions.
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]
Astrobotany – Sub-discipline of botany that is the study of plants in space environments. Archaeoastronomy – studies ancient or traditional astronomies in their cultural context, utilizing archaeological and anthropological evidence. Space archaeology – the study of human artifacts in outer space
In archaeology, a biofact (or ecofact) is any organic material including flora or fauna material found at an archaeological site that has not been technologically altered by humans yet still has cultural relevance. [1] Biofacts can include but are not limited to plants, seeds, pollen, animal bones, insects, fish bones and mollusks. [1]
