Interplanetary explorers
b'In this month\\u2019s instalment, Edward Gomez and I chat about interplanetary explorers to the icy worlds of Pluto and Ceres, and Cassini\\u2019s capture of interstellar\\xa0dust\\xa0as it passed through the Saturn system. And, of course, we look ahead to May\\u2019s Transit of Mercury, which we\\u2019ll be viewing with members of the public and school groups here in Cardiff.\\nFurther afield, in both time and space, is the Breakthough Starshot initiative, which aims to send\\xa0a fleet of tiny\\xa0spacecraft\\xa0to another star system \\u2013 if they can pull it off, that is!\\n\\nOriginally broadcast on 28th April\\xa02016 as part of Pythagoras\\u2019 Trousers on Radio Cardiff.'
