Title: Space Debris: Another Tragedy of the Commons?
Abstract:
Since the successful launch of Sputnik 1 in 1957, the exploitation of space has increased rapidly. Satellites are providing crucial services, e.g., weather forecast, navigation systems, managing disasters, and it would be hard
to imagine our daily life without them. Two notable changes are worth mentioning in this area. First, private companies jumped in, that is, launching satellites is no more a state/government business. Second, there are active plans for launching tens of thousands
of satellites during the next few years. Inevitably, this will create space congestion, and the multiplication of space debris (objects with no function), especially in low orbits, which could ultimately render space non exploitable physically and/or economically.
In this talk, I first discuss some of the main issues related to space debris and remediation strategies. Next, I introduce a dynamic game model that considers the (future) presence of few mega constellations
(e.g., Starlink, Kuiper, OneWeb), and derive the conditions for a sustainable exploitation of space, and therefore avoid another tragedy of the commons.
(Presentation based on joint work with Pierre Bernhard and Marc Deschamps)
We hope to see you there,
