Phase IFoundation

Background

Overview

UPSC cares about international space law and governance as it forms the framework for managing the increasing activities in outer space, including preventing conflict, ensuring sustainability (e.g., space debris), and promoting equitable access and benefits from space exploration. It's vital for understanding global efforts to maintain peace and stability in a new domain.

International space law comprises treaties, principles, and resolutions governing the activities of states in outer space, including the moon and other celestial bodies. Its primary aim is to ensure the peaceful exploration and use of outer space, prevent its weaponization, and promote international cooperation and responsibility.
