What can Pacific island colonization teach us about settling Mars? Archaeologist Thomas Leppard's groundbreaking research in Acta Astronautica reveals eight crucial lessons from humanity's ancient migrations that could determine the success of space colonies.

The study goes beyond engineering challenges to address critical factors: minimum viable populations (1,000+ people), resource distribution, maintaining cultural ties, and the physiological realities of living on Mars or Jupiter's moons.

By analyzing how our ancestors successfully colonized remote islands, researchers have created a science-based roadmap for humanity's greatest adventure—becoming an interplanetary species. Learn why these historical insights matter more than technology alone for long-term extraterrestrial survival.
