2025 – Austin, Texas

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.

The Call for Papers is here!

The symposium’s objective is to foster an exchange on various aspects of interstellar travel, including human and robotic exploration, power systems, communications, system reliability, psychology, crew health, anthropology, legal regimes, ethics, propulsion, potential destinations (including exoplanet research), life support systems, and habitats.

The symposium will include Special Sessions, Keynote Lectures, Working Tracks, Seminars, science fiction author engagement, as well as an art exhibition.
