The British Interplanetary Society was founded in 1933 and has been working for 80 years to take ideas for space exploration from imagination to reality. The Society helped develop early concepts for rockets, satellites, lunar landers, and space stations. Key milestones included publishing some of the first proposals for communications satellites and lunar bases in the 1940s and 1950s. The Society also helped inspire generations of scientists and engineers through publications like Spaceflight magazine. After helping enable early UK and European space achievements, the Society continues working today on advancing technologies and concepts that can enable humanity to explore and utilize space.
