Regina大学天文学者Samantha Lawler研究多项轨道数据中心申请，警告大型卫星群可能改变夜空，影响观星及望远镜观测。论文Rings in the Sky仍在同行评审阶段，其结果是基于拟议数量、轨道及卫星设计的模拟，不是所有设施已经部署后的实测结论。
报道列出SpaceX最多100万颗、Blue Origin最多51,600颗，以及Cowboy Space最多20,000颗卫星的申请方案。企业认为太空太阳能可减轻地面用电、用水及土地压力，但实际批准、部署规模、维护和散热仍有不确定性，不能把申请上限当成确定发射计划。
研究者指出，更大反射面积及较高轨道可能让卫星在夜间更长时间可见，加拿大等北纬地区夏至前后尤其值得关注。卫星碎片再入、碰撞规避及设备维修也需评估；SpaceX则表示可通过推进和轨道预测降低碰撞风险。
报道没有确认美国FCC何时审议这些申请。对加拿大而言，讨论涉及公共资助天文观测、夜空环境及航天规则；研究模拟并非预报普通居民即将被碎片击中。
