Distant Worlds, Neighboring Opportunities
This theme evokes the fact that while truly interstellar missions remain an aspirational goal, all steps that we take now can have far-reaching effects by coloring our immediate challenges.
Just as habitat engineering studies have benefits for improving living in harsh earth environments; studies of culture, law, art, and governance here on earth will have lasting impacts on crewed interstellar missions.
We want to underscore how the breadth of the human experience will determine the success of our expansion to Distant Worlds and stars beyond. Neighboring opportunities reminds us that space is for all.
Meet the Organizing Committee!
