Visualizing the Impact of Space Pollution

Space Trash Signs is an initiative to visualize the consequences of space debris on different aspects of life on Earth. These signs were identified by monitoring real debris orbiting the planet. Each sign depicts the impact of a single consequence of the collective problem that space pollution represents.

The matters of space are discussed in closed conference rooms around the world, and they are barely made accessible to the general public. But we all have the right to participate. After all, our lives on Earth heavily depend on space.

The initiative is open to supporters from all over the world. Our goal is to educate people and inspire action against galactic pollution.

Privateer is creating the data infrastructure that will enable sustainable growth for the new space economy. Privateer’s proprietary knowledge graph technology offers a whole new approach to how information about space objects is collected and processed. Even as orbital highways become more congested, this data and the applications built on it will allow space operators to maneuver safely and effectively. Privateer’s innovative technology ensures the sustainable expansion of the new space economy for generations to come.

European Space Agency

The European Space Agency is an intergovernmental organization of 22 member states dedicated to the exploration of space. In 2022, they announced their “Zero Debris” approach to drive the development of technologies required for no more debris to be left in orbit by 2030. Building on this principle led to the development of the Zero Debris Charter, a community-driven initiative for the global space community which contains guiding principles and specific targets to achieve Zero Debris by 2030.


Astroscale is the only company dedicated to on-orbit servicing across all orbits. Founded in 2013, Astroscale is developing innovative and scalable solutions across the spectrum of on-orbit servicing, including life extension, in-space situational awareness, end-of-life, and active debris removal. Astroscale is also defining the economics of on-orbit servicing and working with government and commercial stakeholders to develop norms, regulations, and incentives for the responsible use of space.
