U.S. GAO, "Large Constellations of Satellites: Mitigating Environmental and Other Effects"
GAO is recommending that FCC review and document whether licensing large constellations of satellites normally does not have significant effects on the environment. FCC同意我们的建议.

Stakeholders across the space industry should recognize the urgency of the need to organize and properly fund a vigorous program of scientific research in order to understand the global impacts of spaceflight.
Depending on the atmospheric residence time of material from re-entered satellites, each mega-constellation will produce fine particulates that could greatly exceed natural forms of high-altitude atmospheric aluminum deposition...
We face an existential crisis: Space is at risk of developing the equivalent of the ocean’s “drifting island of plastic.” Air, space, and light pollution now present looming environmental threats created by the launch of new “mega-constellations” of thousands of satellites...
Treating space as the ‘Wild West’ frontier that requires conquering continues to incentivize claiming by those who are well-resourced.
有足够数量的明亮卫星, these stakeholders could be impacted as well and should be included in deliberations as LEOsat deployment continues.

Thousands of small satellites are being launched into the “lower orbit” of space... concern is growing among atmospheric scientists about how they may harm the protective ozone layer that shields life on Earth from dangerous radiation from the sun.
The recent launch of low Earth orbit satellite constellations is creating a growing threat for astronomical observations with ground-based telescopes that has alarmed the astronomical community.
很难想象还有什么比这更能把夜空弄脏的了. The satellites can be as bright as the stars you can see with your naked eye, 一旦计划完成, 卫星将比恒星多得多.
In early 2020, 有人认为，这种夜晚的变化, 对天文学和公众都是如此, 可能违反了美国宪法.S. environmental law, specifically the National Environmental Policy Act (NEPA).

However, 批评人士警告称，星链项目, and others like it, will lead to light pollution - in the form of streaks that can already be observed from here on Earth.
Without significant, rapid, large-scale action, the night sky will likely be forever changed. 下面是我们能做的.
Astronomers have also raised concerns about constellations on their observations of the universe...
The effect is similar to ground-based light pollution from lamps and other nighttime light sources, 这有效地冲淡了夜空的视觉对比, 使较暗的天文目标更难被看到.

但是天文学界, which has spent decades designing and building sensitive optical equipment tuned to pick up the faintest of glimmers from across the galaxy and beyond, 将同样的景象视为对他们事业的威胁.
当我们每隔几周发射几十颗卫星时, we remove the environment's ability to inform us of the unitended consequences of our actions and we cannot preduct what the dynamic equilibrium state actually is.
