Rosetta's comet touchdown finale
The European Space Agency's Rosetta mission to a comet is about to end. Adam Rutherford discusses its discoveries and looks ahead to its imminent controlled slow-motion crash landing on comet 67P. Also in the programme - the marine excavation of human remains on a 2000 year old ship that sank with the extraordinary Antikythera mechanism: why most human evolution researchers don't rate the aquatic or waterside ape hypothesis: and H.G Wells, the science communicator.
