Britain challenges Nasa in race for Mars rock sample The Weekly Telegraph

British space scientists are proposing an ambitious project to send an unmanned probe to Mars and return with a piece of the planet. The mission would pave the way for the most detailed research yet into the history of Mars and whether it was once home to life. If the proposals get the backing of the European Space Agency, the team will bring the first freshly-mined Martian rock to Earth years before Nasa.
