"The fact that the #EU #Space Act establishes some binding measures regarding collision avoidance, information sharing, cybersecurity, and other space activities will break with past reluctance to go down that path and establish a new model. The United States and other stakeholders will find new challenges to their preference for laissez faire-driven space traffic management and space sustainability policies."

"With over 34,000 large debris pieces in orbit and millions of smaller fragments, the threat of collisions and the #KesslerSyndrome looms large. International cooperation, stringent regulations, and technological solutions are proposed to address the crisis, emphasizing the need for a comprehensive global framework to ensure #SpaceSustainability for future generations."

Bad news for the impact of increasing rocket launches on the terrestrial #environment: "Our ‘ambitious’ scenario (2,040 launches/year) leads to a -0.29% depletion in annual-mean, near-global total column #ozone, relative to a simulation with no rocket launches. Antarctic springtime ozone decreases by 3.9%. Our ‘conservative’ scenario (884 launches/year) leads to a -0.17% annual depletion; current licensing rates suggest this scenario may be exceeded sooner than 2030."

To understand if significant ozone losses could occur as the launch industry grows, we examine two scenarios of industry aspirations. Our ‘ambitious’ scenario (2,040 launches/year) leads to a ...

"This potential treasure hunt in space has sparked discussions about ownership laws, space ethics, and environmental implications. As these celestial bodies could herald an era where space becomes a frontier for industry and sustainable energy, they invoke questions about the regulation of extraterrestrial resource claims."

Science Magazine · Asteroids to Power the Future? Space Mining Revolution Begins! - Science MagazineAsteroid mining is becoming a realistic prospect due to advancements in space technologies, offering possibilities for resource extraction and energy transformation. Governments and companies are investing in missions targeting asteroids, which are rich in valuable minerals like platinum, gold, and rare earth elements. Asteroids contain water, which can be converted into hydrogen and oxygen for fuel, enabling sustainable future space exploration. The pursuit of asteroid resources has initiated conversations on ownership laws, space ethics, and environmental implications. This initiative could alter economic principles and enhance space travel, offering potential solutions to Earth’s resource scarcity. Asteroids, those rocky bodies floating in

Here is a run-down on Dark & Quiet Skies activities at the recent UN COPUOS Science & Technology Subcommittee meeting from @iau_cps: cps.iau.org/news/un-meeting-fe

"The discussion included remarks on the need to find balanced solutions, the urgent need for nations to support research on mitigations, considerations on the cultural heritage of the night sky, and the importance of space sustainability discussions within international bodies."

"[W]hile [astronomers] continue to work on satellite interference issues, they are expanding their work to other topics broadly associated with space sustainability. These issues range from the threat of obtrusive space advertising and reentries that interfere with their observations to the danger of confusing asteroids with flying Teslas."

"Uncontrolled space debris raining down toward Earth is becoming a serious concern as activity in the skies ramps up."

Science Magazine · Skyfall: Why Uncontrolled Space Debris Could Threaten Your Flight - Science MagazineUncontrolled space debris poses a growing risk to aircraft due to increased space activities. The FAA’s prompt investigation into SpaceX highlights the urgency of managing space debris incidents. A new study indicates a 26% annual chance of uncontrolled debris reentering busy airspaces. Air travel growth and rising space missions complicate safety regulations for air traffic. Over 2,300 rocket bodies still orbit Earth, underscoring the ongoing debris management challenge. Proposed solutions include mandatory controlled ocean landings to reduce risks associated with space debris. There is an urgent need for enhanced safety protocols as space exploration continues to expand. Uncontrolled space debris

EU Statement at the 62nd Session of the Scientific and Technical Sub-Committee of the United Nations Committee on the Peaceful Uses of Outer Space, 3 February 2025: eeas.europa.eu/delegations/vie

"The EU and its Member States strongly support the rules-based international order, with the United Nations at its core, and a multilateral approach to international affairs."

Includes an appeal to "the universalisation of the Outer Space Treaty for the preservation of a secure, safe, stable and sustainable outer space environment."

All activities of States in exploration and use of outer space must be conducted in accordance with the Outer Space Treaty, and we encourage all States to ratify it and fully implement ts provisions. We underline the importance of the niversalisation of the Outer Space Treaty for the preservation of a secure, safe, stable and sustainable outer space environment. Together, States need to uphold this Treaty and other key instruments within the United Nations framework, to develop further transparency and confidence-building measures, and foster responsible behaviour in the peaceful and free exploration of outer space.
