Ex Parvis Initiis, Magnitudo – "From Small Beginnings, Greatness."​

​​

The Cosmouse Mission Series will be conducted as the first of three major research phases on mammalian reproduction in space.  They are designed to build on a small number of mammalian reproduction research missions conducted by NASA and other national space agencies since the late 1970s, such as Kosmos--1129, Neurolab, and Rodent Research-20. The Cosmouse missions will examine each stage of mammalian gestation in Low Earth Orbit (LEO) spaceflight using mice and rat subjects.

​

The experiment series will culminate with the launch of a research module modeled off of MICEHAB, a NASA--conceived orbital rodent colony – allowing scientists to observe the impacts of long-term exposure to microgravity and Galactic Cosmic Radiation (GCR) to mammalian reproductive health over the course of multiple generations.  The Cosmouse experiments will serve as crucial first steps in determining safe and viable parameters for eventual human reproduction in space environments in the coming decades.
