The Space Debris Challenge to the Sustainability of the Space Economy

While our modern world is today unimaginable without space, the space landscape is changing fast. For long near space has been a vast resource to exploit with few limits. This situation is however changing since in reality orbital resources are scarce and are threatened by the growth of the space debris population. Space debris is one of the human -made problems along the climate crisis, air pollution or ocean plastic pollution among other environmental issues that keep growing despite the awareness of their dangers to societies and our economies. The debris population has been growing drastically over the years due to the increase of rockets and satellites launches, accidental collisions of space objects, as well as deliberate Anti -Satellite Tests (ASAT s). Addressing appropriately the space debris issues is today an unescapable necessity to allow realising the deployments of the planned space constellations in a responsible manner. This would also provide stability and continuity to space activities so that the public and commercial sectors can continue to innovate and invest in new ventures that continue building a robust space economy. This paper discusses the direct and collateral challenges of space debris on the space economy and presents technological and political actions needed to face this growing problem for the present and future generations.
