Microgravity Centre, PUCRS. The Microgravity Centre (Centro de Microgravidade), colloquially known as the "MicroG", [1] at PUCRS university, Porto Alegre, Brazil, was initially created as a laboratory in 1999 [2] by Professor Thais Russomano MD MSc PhD, as the first [not verified in body] academic and research establishment dedicated to Space Life Sciences in Latin America.
Researchers are investigating the effect of the station's near-weightless environment on the evolution, development, growth and internal processes of plants and animals. In response to some of this data, NASA wants to investigate microgravity 's effects on the growth of three-dimensional, human-like tissues, and the unusual protein crystals ...
Gravitational biology is the study of the effects gravity has on living organisms. Throughout the history of the Earth life has evolved to survive changing conditions, such as changes in the climate and habitat. However, one constant factor in evolution since life first began on Earth is the force of gravity.
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.
Disks Flown on STS-40 STS-40 Cargo Bay configuration. G-616, formally known as GAS canister #G-616: The Effect of Cosmic Radiation on Static Computer Media & Plant Seeds Exposure to Microgravity was an experiment flown on the Space Shuttle as a self-contained experiment, as part of STS-40.
Several ground-based paradigms have been used to emulate the effects of microgravity unloading on human skeletal muscle, including complete horizontal or 6° head-down-tilt bed rest, dry immersion, and unilateral upper- and lower-limb unloading with or without joint immobilization. In general, skeletal muscle responses to unloading have been ...
In the case of the Earth, the effects are minor, especially on objects of relatively small dimensions (such as the human body or a spacecraft) and the overall sensation of weightlessness in these cases is preserved. This condition is known as microgravity, and it prevails in orbiting spacecraft.
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]
