On this week's Naked Scientists, we seek the start of the solar system. We'll be finding out how clouds of gas and dust can clump and diversify to become stars, asteroids and the planets we know so well. Plus, we find out what happens to sculpt the surface of planets, and how the Rosetta mission will be the first craft to land on a comet! Also,how the smell of old books can help to preserve them, deleting old memories to make room for new ones and the frightening rate of Greenland ice loss. Plus, in Kitchen Science, Ben and Dave explain how margarine and meteorites tell us about Earth's origins!

Were the red sands of Mars caused by biological activities because when the levels of oxygen rose on Earth billions of years ago, large quantities of iron rusted out of the atmosphere, and that left iron oxide deposits in rocks. So could the same thing have happened to Mars?
