Call to Protect the Dark and Quiet Sky from Harmful Interference by Satellite Constellations
The growing number of satellite constellations in low Earth orbit (LEO) enhances global communications and Earth observation, and support of space commerce is a high priority of many governments. At the same time, the proliferation of satellites in LEO has negative effects on astronomical observations and research, and the preservation of the dark and quiet sky. These satellite constellations reflect sunlight onto optical telescopes, and their radio emission impacts radio observatories, jeopardising our access to essential scientific discoveries through astronomy. The changing visual appearance of the sky also impacts our cultural heritage and environment. Both ground-based observatories and space-based telescopes in LEO are affected, and there are no places on Earth that can escape the effects of satellite constellations given their global nature. The minimally disturbed dark and radio-quiet sky is crucial for conducting fundamental research in astronomy and important public services such as planetary defence, technology development, and high-precision geolocation. Some aspects of satellite deployment and operation are regulated by States and intergovernmental organisations. While regulatory agencies in some States have started to require operators to coordinate with their national astronomy agencies over impacts, mitigation of the impact of space objects on astronomical activities is not sufficiently regulated. To address this issue, the CPS urges States and the international community to take steps to protect the dark and quiet sky as specified in this paper.
DoomsdaysCWAre We Going to Mess Up Outer Space Too?
As nations jockey for military edge in orbit, there is a growing threat from above

"Over the past decade, however, space has become much more contested and harder to govern. Nearly 1,000 private companies now offer space-based products and services. Expanding #SatelliteConstellations offer better internet access in remote and developing communities, enabling more people to access online health care, work remotely, and connect with family and friends. Space technologies also support better weather and climate monitoring, improve navigation and transportation logistics, and enhance agricultural productivity through the use of land- and water-quality sensors. All this has contributed to a space economy with an estimated value of $447 billion (US), on a trajectory to reach $1 trillion by 2030. And missions focused on exploration and scientific discovery are expanding—including the US-led Artemis program that aims to land human beings on the moon for the first time in over fifty years.
"But this new space age poses substantial risks. #OrbitalDebris from inactive satellites, discarded rocket parts, and anti-satellite #weapons tests threatens the infrastructure on which our social and economic well-being now depends, as well as the lives of astronauts working on space stations. In addition to the 30,000 objects large enough to track, there are an estimated 1 million debris fragments—between one and ten centimetres in diameter—that are too small to be picked up by ground-based radar and surveillance networks. Experts put the likelihood of future collisions between these objects at near certainty, with potential for cascading and catastrophic damage including entire satellite communication systems being taken out and larger debris fragments falling to #Earth and threatening lives and #ecosystems."

Protecting ALMA's Skies | ALMA
The Atacama Large Millimeter/submillimeter Array (ALMA), renowned for observing the cosmos's darkest and most distant corners, has taken a step to ensure its observations remain unaffected by human-made interference. A recently concluded study, led by senior Radio Frequency (RF) engineer and Spectrum Manager Giorgio Siringo, alongside ALMA Director Sean Dougherty, presents an extensive analysis of...
