• Plan produced in the 1970s by members of the British Interplanetary Society for an unmanned rocket mission to Barnard’s Star, powered by fusion motors. Project Daedalus is unlikely to be carried out in the near future, not least because it would require huge amounts of helium 3 as fuel, ‘mined’ from the atmosphere of Jupiter or Saturn. But Barnard’s Star remains a tantalising target because unlike nearer star systems like the Alpha Centauri group it seems to have at least one planet.
