🌌 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.

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

https://fed.brid.gy/r/https://spacenews.com/colliding-space-debris-produces-radio-bursts-raising-prospect-of-debris-weather-alerts/

"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."

"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."

"[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."

“As a result of this low skill in our forecasts, #SpaceX saw 20 kilometers of position error in their one-day computations. If we’re uncertain in where our spacecraft are by 20 kilometers, then you can throw collision avoidance out the window.”

"The sharp altitude decay of SL1089 revealed by TLE data coincides with the storm main phase onset. Therefore, we call for future research to establish the eventual causal relationship between storm occurrence and satellite orbital decay."

"We need to initiate discussions as soon as possible. With space debris, it took us 20 or 30 years to define a solution. With [the satellite air pollution] problem, if we move on the same kind of timescale, it might be too late."
