A visit to the British Interplanetary Society's London headquarters, the world's oldest space advocacy group founded in 1933, finds members like 71-year-old fellow Jerry Stone still preoccupied with the prospect of human missions to Mars. The society's library holds decades' worth of books and speculative literature on Martian exploration, propulsion systems and colonization schemes.
