European space probe lands on comet

The landing of a European space probe on a comet 500m km away has caught the world's imagination. Philae, launched from the Rosetta satellite, is sitting on the head of the comet - its scientific instruments are working, but it is not properly anchored. Clive Cookson, FT science editor, asked space scientist Ken Pounds what the project may reveal about the history of the solar system. Hosted on Acast. See acast.com/privacy for more information.
