Mars Rising

So I watched this awesome show on the the discovery science channel called Mars Rising. Its a new series and they talk about some really interesting things pertaining to Mars. Yesterday they talked about the problems that humans would face if they were to take a manned mission to Mars. One of the main problems would be atrophy of the muscles. Departments at MIT and CAL are working on ways to prevent muscle atrophy from taking place. They are constantly trying new methods because a trip to Mars would take months and months and atrophy is a serious problem. Another issue they talked about was radiation. It's a really interesting show and if you got some spare time you should watch it.
