Regina大學天文學者Samantha Lawler研究多項軌道數據中心申請，警告大型衛星羣可能改變夜空，影響觀星及望遠鏡觀測。論文Rings in the Sky仍在同行評審階段，其結果是基於擬議數量、軌道及衛星設計的模擬，不是所有設施已經部署後的實測結論。
報道列出SpaceX最多100萬顆、Blue Origin最多51,600顆，以及Cowboy Space最多20,000顆衛星的申請方案。企業認爲太空太陽能可減輕地面用電、用水及土地壓力，但實際批准、部署規模、維護和散熱仍有不確定性，不能把申請上限當成確定發射計劃。
研究者指出，更大反射面積及較高軌道可能讓衛星在夜間更長時間可見，加拿大等北緯地區夏至前後尤其值得關注。衛星碎片再入、碰撞規避及設備維修也需評估；SpaceX則表示可通過推進和軌道預測降低碰撞風險。
報道沒有確認美國FCC何時審議這些申請。對加拿大而言，討論涉及公共資助天文觀測、夜空環境及航天規則；研究模擬並非預報普通居民即將被碎片擊中。
