12 January 2018. In the past decade, the count of trackable debris fragments has more than doubled, driven by collisions in space, several high-profile ASAT tests, the proliferation of cubesats and growing number of upper stages left in orbit. Additional European leadership will be needed to fully respond to the emerging space traffic challenges presented by various trends including the incoming LEO mega-constellations and increased risk of collisions. The ESPI Brief 19 provides an overview of the growing concern of orbital debris, Europe’s efforts in this domain, and proposes a way to break the international deadlock in debris mitigation efforts.
