An astronaut in outer space with a view of the [[Earth reflected on his visor |thumb]] Bioastronautics is a specialty area of biological and astronautical research which encompasses numerous aspects of biological, behavioral, and medical concern governing humans and other living organisms in outer space; and includes the design of space vehicle payloads, space habitats, and life-support systems. In short, it spans the study and support of life in space.

This is expressed as being greater than 1 g. Hypergravity conditions are created on Earth for research on human physiology in aerial combat and space flight, as well as testing of materials and equipment for space missions. Manufacturing of titanium aluminide turbine blades in 20 g is being explored by researchers at the European Space Agency (ESA) via an 8-meter wide Large Diamet
