Plants grown inflight experience a microgravity environment, and plants grown on the surface of Mars experience approximately 1/3 the gravity that Earth plants do. However, plants experience normal growth given that directional light is provided. [10] Normal growth is classified as opposite root and shoot growth direction.
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]
Tikhov's research into astrobotany would later develop into research into growing plants in space, or demonstrating the possibility of plants to grow in extraterrestrial conditions (especially comparing the climate of Mars and Siberia), but he was the first known astronomer to use color to attempt to measure the level of vegetation on an ...
Among various payloads and experiments were eight cowpea seeds ISRO had sent to space onboard the rocket to study plant growth in microgravity conditions, which germinated within four days of the ...
A Veggie module weighs less than 8 kg (18 lb) and uses 90 watts. [7] It consists of three parts: a lighting system, a bellows enclosure, and a reservoir. [8] The lighting system regulates the amount and intensity of light plants receive, the bellows enclosure keeps the environment inside the unit separate from its surroundings, and the reservoir connects to plant pillows where the seeds grow.
A plant only reacts to gravity if the gravistimulation is maintained for longer than a critical amount of time, called the minimal presentation time (MPT). For many plant organs the MPT lies somewhere between 10 and 200 seconds, and therefore a clinostat should rotate on a comparable timescale in order to avoid a gravitropic response.
