2026 EDITION
The Top 100 Lists
Two parallel lists — the Top 100 Space Colonization Companies and the Top 100 Space Colonization Researchers — organized across the Ten Tiers. The 2026 Edition is in preparation.
Top 100 Space Colonization Companies
The companies building the industrial infrastructure of the Moon-to-Mars economy — ten per tier across the Ten Tiers.
Top 100 Space Colonization Researchers
The researchers advancing the science that keeps people alive and productive off Earth — ten per tier across the Ten Tiers.
The Top 100 Space Colonization Companies and Top 100 Space Colonization Researchers lists are determined solely by the independent editorial committee. Paid advertisers, sponsors, and job board customers are not eligible for listing consideration or influence. Entries are not ranked or scored against each other — within each tier they are listed alphabetically and treated as equals.
