I4IS = Initiative for Interstellar Studies 英國非營利組織「星際研究倡議」
Project Dragonfly is a feasibility study for an interstellar mission, conducted by small, distributed spacecraft, propelled primarily by laser sails. The spacecraft shall be capable of reaching the target star system within a century and be able to decelerate. We believe that such a mission can be conducted with technology available by 2024-2034 as well as a space infrastructure, available by 2050.
