Philae lander detects organic molecules on Comet 67P Rosetta scientist, Professor Monica Grady from the Open University discusses the latest news from last week's historic comet mission. Philae, the Rosetta robot probe, made history last week when she finally landed on the surface of Comet 67P. But she ended up lying on her side, and only in partial sunlight. Her batteries were on borrowed time. After around 60 hours, Philae powered down, and went into hibernation mode. However, her instruments harvested some data and now the first results are in. UK-led crowdfunded Moon mission Lunar Mission One aims to land a robotic spacecraft on the unexplored lunar South Pole by 2024. It's a space mission with a difference: it could be funded by you. For a small fee supporters can send a human hair to the Moon in a Blue Peter-style time capsule. And the spacecraft will drill up to 100 metres below the surface to ask questions about the Moon's origin, aiming to find out more about the minerals that exist there, several of which are potentially valuable. Our reporter Sue Nelson went to the British Interplanetary Society's Reinventing Space conference in London to hear more. The Selfish Gene debate As another bout of biological warfare breaks out between two scientific superpowers, Adam Rutherford gets to grips with evolutionary theory, with social insect expert Professor Adam Hart. He hears from Richard Dawkins and E.O. Wilson and finds out why, after forty years of promoting the idea of kin selection, E O Wilson now dismisses the whole idea as 'rhetoric'. Presenter: Adam Rutherford Producer: Anna Buckley Assistant Producer: Jen Whyntie.
