Threshold Acceleration for Gravisensing - 2 (Gravi-2) - 12.03.13
Science Objectives for Everyone
Threshold Acceleration for Gravisensing - 2 (Gravi-2) grows lentil seedling roots under various gravity conditions on board the International Space Station (ISS) to determine the amount of acceleration force sufficient to stimulate the direction of root growth.

Any research in plant biology will help for future long-range space missions where plants are planned to be an essential part of a bio-regenerative life support systems. The use of plants to provide a reliable oxygen, food and water source could reduce the resupply requirements for the International Space Station (ISS), and provide sustainable sources, such as fresh food, necessary to make long-duration missions more feasible. However, before plants can be effectively utilised for space exploration missions, a better understanding of their physiological behaviour under weightlessness is essential.Earth Applications
The experiment will allow scientists to better understand the role gravity plays in plant growth and development, in particular the mechanisms by which a plant root perceives and responds to a change in the direction of the gravity vector. Any advances made to plant cultivation techniques in weightlessness could also improve our knowledge of such processes on Earth.
