Discussion of US space policy, centred on the FCC's role in approving satellite constellations. Posts criticize Amazon's request to launch 5,105 satellites while keeping debris-risk models secret, and a startup plan to beam sunlight to Earth, which environmental groups are petitioning the FCC to reverse. Astronomers warn constellations are far brighter than recommended thresholds, threatening the night sky and research, while experts note risks from orbital debris and weak regulatory oversight.
