Russian space researchers will lock six men in a metal tube for more than a year in an effort to mimic the stresses and challenges of a manned mission to Mars.
Researchers are working on setting up a global positioning system for the Red Planet to aid future scientific exploration and development.
Finding life on Mars has proved an elusive dream for decades. But scientists now believe they may be able to do it for themselves - by turning the Red Planet into a blue world with streams, green fields and fresh breezes and filling it with Earthly creatures.
The new Bush space initiative is doomed to failure because a multi-decade government program is unsustainable, argues Phil Smith. Instead, the government needs to stoke the engine of commerce in order to create a sustainable human presence in space.
