Philip Linden | Space Time Card @ Vision Weekend Puerto Rico 2026
Summary
Philip Linden discusses the development of a space time card aimed at addressing lunar time coordination challenges. He emphasizes the importance of precise timing for navigation, communication, and event ordering in space, arguing that a unified timing system is essential for a cohesive cis-lunar economy.
Linden highlights the potential of decentralized shared infrastructure to promote cooperation among space missions. By distributing the cost and risk across multiple missions, he advocates for a system that allows for rapid iteration and development of timing solutions.
He presents a prototype developed by the Rochester Institute of Technology, which aims to create a functional clock suitable for space applications. Linden encourages collaboration and innovation within the engineering community to enhance the capabilities of timing systems.
Linden addresses the complexities of time coordination, noting that while simultaneous timekeeping is impossible due to relativistic effects, coordination among different systems is crucial. He stresses the need for peers to agree on time to avoid operational failures.
