At its Stanford convention, the Mars Society resolved to commit its resources to initiate the Translife Mission as its first spaceflight mission project. The Translife mission will consist of a Mars-level (0.38 g)artificial gravity spacecraft carrying a crew of mice (and possibly other animals and plants) in low Earth orbit for a period of roughly two months. During this period, the mice will be allowed to reproduce and the young will develop into adults. The spacecraft will then be brought down to Earth, and both the original crew and their progeny will be examined.
