Human spaceflight raises ethical, cultural, and legal issues as science fiction becomes reality. Growing projects to settle the Moon, Mars, low-earth-orbit satellites, and other celestial bodies raise important questions about cultural preservation and interplanetary human rights. This article examines how space-faring human clusters could preserve Earth's cultures while creating new identities in alien communities. Without legal frameworks, space science and commerce may compromise cultural continuity and human rights. Current space governance systems cannot address cultural preservation and human rights in space settlement, like the 1967 Outer Space Treaty. This research emphasizes the need for new laws to protect space explorers' human rights and cultural heritage. This study promotes proactive governance in accordance with international human rights law to preserve Earth's cultural legacy, create new cultural identities in space, and protect intellectual property. International cooperation and multidisciplinary research could guide space exploration and human settlements using ethical guidelines that respect human dignity and promote cultural diversity and invention.
