COMPASSE represents the interests of AAS relating to the protection of dark and radio-quiet skies, the safe and sustainable use of outer space, and related issues, and empowers AAS members to be effective advocates for the protection for U.S. Astronomy.
Primary Concern: Impacts on access to the night sky and impacts on astronomical science.
Key Issues:
• Artificial Light at Night
• Increasingly crowded orbital space
• Preservation of observational environments

• Kyba et al. 2023 - an increase of sky brightness of 7%-10% per year.
• Falchi et al. 2023 - two-thirds of large observatories have surpassed the critical 10% increase in radiance above natural levels.
• In 2023 media coverage of light pollution doubled.
• Nature Astronomy Dark Skies collection (March 2023). Science special edition (June 2023).
•  Astrotourism valued at &gt;$1 billion.

Consider environmental impacts of ALL phases of SatCons (assembled by James Lowenthal and Diana Umpierre)
* Launch
- Air pollution, greenhouse gases
- Noise pollution, falling debris, explosions
- Environmental justice and equity
*Operation
- Visual appearance of night sky
- Sovereignty
- Animal navigation / migration
- Diffuse sky brightness
- Earth observation satellites
- Orbital debris, collisions (Kessler Syndrome)
* Deorbit
- Aluminum/heavy metal deposition during re-entry
- Re-entry and deorbit failures
- Uncontrolled/unplanned space object or debris landings
International cooperation and agreement are needed UNOOSA #Space Sustainability (2021)</a></label><br><a href="https://cdn.masto.host/astrodonsocial/media_attachments/files/112/599/400/951/164/578/original/d5d678a39f2daeca.png" rel="external">https://cdn.masto.host/astrodonsocial/media_attachments/files/112/599/400/951/164/578/original/d5d678a39f2daeca.png</a></li></ol></footer></blockquote>

Day 2 of #AAS244
First plenary: Dark and Quiet Skies for the Future of Astronomy and of the Space Environment, Aparna Venkatesan and Teznie Pugh, AAS Committee to Protect Astronomy and the Space Environment (COMPASSE).
The committee is trying to reduce the impacts of artificial light, EM interference, and satellite constellations.
The news is depressing. I will impact more than just astronomers: cultural sky traditions, environmental degradation, astrotourism, amateur astronomers, and more.
