This may be about to change with a $1 billion mission to drill 6 km (3.7 miles) beneath the seafloor to reach the Earth's mantle — a 3000 km-thick layer of slowly deforming rock between the crust and the core which makes up the majority of our planet — and bring back the first ever fresh samples."

The Mini Cooper-sized Mars Science Laboratory, which is now named Curiosity, will crawl the Martian surface under steam from a nuclear powerplant — but it's a gentle giant compared to its predecessors. Recent theories have emerged that previous attempts at identifying organic compounds in Martian soil may have actually cooked away any signs of life-giving elements. Curiosity will go to great pains to avoid scorching the Earth ... erm ... Mars."
