Students and researchers at MIT are designing a space mission to learn about the effects of Mars-level gravity using pint-sized astronauts. The 15 mouse-trounauts will orbit Earth for five weeks to help researchers learn how Martian gravity—about one-third that of Earth—will affect the mammalian body. The goal of the Mars Gravity Biosatellite Program is to send the mice into near-Earth orbit inside a one-meter space ship simulating Mars’ gravity, then bring them back to Earth. It won’t be the first time mice have flown in space, but it will be the first time mammals of any kind have lived in partial gravity for an extended period. The spin of the spacecraft will create an effect on the mice equivalent to Mars’ gravity.
