An experiment conducted at Pioneer Astronautics for the Mars Society has demonstrated that the Coriolis forces that mice will be exposed to during the Translife Mission will not be excessive. Coriolis forces are a secondary byproduct of rotating artificial gravity systems. It has long been argued by advocates of zero-gravity space travel that such forces would prove disorienting to astronauts, especially at rotation rates above 4 revolutions per minute. The Mars Society’s Translife Mission will place a group of mice in low Earth orbit for about 50 days in a rotating spacecraft that will supply them with artificial gravity at Mars levels, 38% that of the Earth. During this time, the mice will be allowed to reproduce and the young will grow up in Martian gravity.
