Kirsty Young's castaway is the scientist Professor Colin Pillinger. A world-class planetary scientist, his first job was for NASA, analysing the lunar samples brought back by Apollo 11. He is best known, though, for being the public face of Beagle 2, the daring mission to search for life on Mars. Although Beagle 2 was unsuccessful, he is adamant that the mission was not a failure. Now it is hoped that the technology developed for the mission to Mars can be used to diagnose TB faster than has ever been possible before.[Taken from the original programme material for this archive edition of Desert Island Discs]Favourite track: As Time Goes By by Johnnie Ray Book: Journey into Space by Charles Chilton Luxury: A picture of the Clifton Suspension Bridge.
