🌌 Above us, an invisible constellation grows. Not of stars, but of our own making: fragments racing through the dark at unfathomable speeds, each piece a ghost of ambition turned hazard.

💫 What we send skyward returns as legacy, sometimes circling for decades or longer in silent judgment.

Colliding space debris produces radio bursts, raising prospect of ‘debris weather’ alerts

The advent of reusable rockets led to a dramatic increase of space waste influx into the atmosphere - thanks to non-reusable upper stages. About half of the influx is coming from Space Karen. From a recent paper by Schulz et al. https://arxiv.org/abs/2510.21328 #SpaceSustainability

What a disappointment! The proposed #EU Space Act does not include any measures to reduce the environmental impact of the space sector. Only a lifecycle analysis needs to be done, yet this does not reduce environmental impacts! So as usual, the only sustainability action will be a recognition that our activities are not sustainable 🤡 #SpaceSustainability

What a great idea to invent more and more machines that burn fossil fuels 🤪

Humanity is trashing the Moon by dumping its garbage on it. And they call it Resilience. #SpaceSustainability

"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."

Springer International has just released "Space Ecology: From Earth to Moon and Mars", by Patrizia Caraveo. The book "extends the concept of environmental protection to orbital space, which should be used in a sustainable way."

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."

"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."

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

Meanwhile, although I never imagined I would agree with the government of #Iran about much, here we are. "Another critical consequence of the unchecked expansion of mega-constellations is light pollution."

"'It's a very difficult problem to communicate to the general public. It's not like an oil spill, where the pelicans are dying. It's not visceral. There's debris you can show them through a telescope. But it's just a dot.'"

"During the conference launch, Joanne Wheeler, Director of ESSI, highlighted a crucial yet often overlooked aspect, namely: 'Space is part of our Earth’s ecosystem – our home,' and 'What we do in space is an extension of our life on Earth.'"

"[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."

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: https://www.eeas.europa.eu/delegations/vienna-international-organisations/eu-statement-62nd-session-scientific-and-technical-sub-committee-united-nations-committee-peaceful_en
"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."

Ende September letzten Jahres hatte ich das Vergnügen, bei den Bochumer Weltraumtagen der AMSAT-DL einen Vortrag über Weltraumschrott-Vermeidung halten zu dürfen. Seit kurzem ist der nun online.

Can we really achieve a "zero debris" future in orbital space? The European Space Agency thinks so, and it offers this prescription for how to get there.
Among its chief objectives: "protect dark and quiet skies".
