Mars Gravity Biosatellite will provide the first data on the adaptation of the mammalian body to the partial gravity of 0.38g found on the surface of Mars. It will help provide answers to one of the critical outstanding questions in the planning of future human expeditions to the Red Planet. Mars Gravity is led by the Massachusetts Institute of Technology (MIT), the University of Washington (UW) and the University of Queensland (UQ). In this edition: 1.

Students and researchers at the UW have a dream that one day, humans will be able to explore every part of the universe. They are making their dream a reality by designing a mission to determine mammals' response to the reduced-gravity environment of Mars. The program, called the Mars Gravity Biosatellite Program, is the collaborative effort of the UW, MIT and the University of Queensland in Australia.
Astronauts experience many detrimental changes in their bodies when they leave the 1g environment of Earth and travel in microgravity (0g). Such changes including loss of bone mass and muscle atrophy. We know a great deal about life in 0g thanks to numerous missions aboard the shuttles and the International Space Station; but now scientists are starting to wonder what will happen to humans living in environments like Mars, which experience a fraction of Earth's gravity. At .38g, is Mars gravity enough to keep human explorers healthy? Will they be able to readapt when they return to Earth?
From long experience on the space shuttle and various space stations, we have some knowledge of how mammals, especially people, respond to 0-g. We have even more experience with 1-g on Earth. But we still don't know what happens in between. What, for example, will happen to humans on Mars where the surface gravity is 0.38-g? Is that enough to keep human explorers functioning properly? And, importantly, how easily will they readapt to 1-g, once they return to Earth? In 2006 a group of mice-astronauts will orbit Earth inside a spinning spacecraft. Their mission: to learn what its like to live on Mars.
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 mouse cages will be designed for comfort and protection with room for the little travelers to lope around for exercise in the simulated gravity of Mars.

Move over, Disney Mouseketeers – here come the Mousetronauts. In a world first, University of Queensland engineers have said they will help blast 11 mice into space in an endeavour to understand the biological effects of low gravity. Four of the furry astronauts would be pregnant when they entered orbit some time in 2005. If all went according to plan, they should give birth during the 49-day mission. UQ manager for the Mars Gravity Biosatellite Project Jason Hoogland said the experiment was vital for determining whether human beings could withstand a mission to Mars, which would take at least three years in low to zero gravity.
SCIENTISTS plan to send pregnant mice into space to find out if mammals can colonise Mars. University of Queensland PhD engineering student Jason Hoogland today said the planned 2005 mission would be a world first with 11 mice launched into space to orbit the earth in a small rocket, including four which were pregnant.
Before man goes to Mars, mice will go to lava caves. And Central Oregon this weekend will host two pioneer rodents in what could become one giant step toward space exploration. For 48 hours, two female mice, Chevy and Pontiac, will live in a "life bubble" in Skylight Cave near Black Butte. The bubble could become the prototype of what will be used in the future when humans explore the galaxy.
Mouse-tro-nauts are about to become the next pioneers in space, leading the way to Mars, it seems. The University of Queensland is joining two American universities to send mice out there to test how mammalian bodies cope with long journeys and low gravity, even giving birth.
