2. Need for more information and communication
Communities want more information and dialogue. Astronomers and other parties concerned about the impacts of LEO satellite constellations need to engage, listen, share, and act with affected constituencies, government agencies, and cultural, grassroots, and political leaders. Decision-makers and private satellite operators must intentionally invite the voices and groups that have historically been excluded from the power structure and decision-making regarding space activity. Involving youth is a key aspect to co-creating solutions together to protect the Earth and skies that they will inherit.
3. Engage with industry
Astronomers and other interested and affected groups need to continue to engage with the satellite industry to build relationships and find common ground. The Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference proposed by the International Astronomical Union (IAU) is one possible venue for such engagement.
4. Recognize and rebalance power structures
Decision-makers and advocates for the regulation of LEO satellites should recognize the economic, legal, and political structures that continually affect technology choices. The regulatory process must take those power structures into account to optimize societal and environmental benefit with equity — power over a global commons comes with responsibilities to the global good. The social systems of economic and technological opportunities that enable satellite constellations focus on technological solutions; but there is only so much back-correcting that software can do to remove satellite streaks in images, or that engaging affected communities in dialogue, reports, and conferences can do to make amends once irreparable damage is done to the sky and to communities — just as removing plastics from the ocean is proving an impossible task. We urge the broad inclusion of all affected communities in meaningful dialogue from the start.
At the same time, there has been an enormous amount of volunteer labor from mainstream astronomy, communities and institutions devoted to addressing the challenges posed by satellite constellations. Funding for training and FTEs from agencies and industry is needed for continued efforts in the future.
5. Learn from the past
History offers valuable lessons on many issues of concern with satellite constellations, including environmental concerns, loss of millenia-old practices, and the painful legacies of colonization. The past century in particular offers ample examples of disruptive technologies that have been developed first and regulated only later, with varying degrees of cost, benefit, risk, and impact, e.g., telephones, trains/ planes/cars, fossil fuels, and the Internet itself. Examples of global challenges requiring international collaboration include damage to the ozone layer, for which corrective action has been largely successful, and climate change, for which a global course of corrective action has remained elusive. We must learn from those examples as we grapple with the satellite constellation challenge.
