The National Space Society (NSS) is calling for submissions to the 2025 NSS Gerard K. O’Neill Space Settlement Contest. Submissions must relate to free space settlements. Settlements may not be on a planet or moon, although support activities such as mining may be. Settlements must be permanent homes, not temporary work camps. Typically, what distinguishes an outpost from a settlement is generational habitation. Submissions may focus on one or a few aspects of space settlement and supporting systems, including mines, activities leading up to settlement (such as space hotels), economic and social issues, etc. The best submission, regardless of category, wins the grand prize. The submission will be hosted on the contest web site. Finally, the highest ranking entry whose student(s) attend(s) ISDC will receive the Herman Rubin Memorial Scholarship of $5,000 and give a talk at the conference.
