企業が宇宙ごみ除去を追求する
thousands of satellites and spent rocket stages are crowding low-Earth orbit, and a spent SpaceX Falcon 9 upper stage recently crashed into the moon after being left on an uncontrolled trajectory. Defunct satellites and rocket parts can remain for years, creating collision risk and producing fragments too small to track; OrbitRadar counts about 30,000 objects with roughly 18,500 active satellites. Companies such as Astroscale and ClearSpace are building docking, capture and servicing systems and securing government grants and contracts, but funding challenges, legal responsibility and the need for regulation are central barriers to a sustained commercial market.
Regulation is needed to create commercial demand for debris removal
背景
Many satellites and spent rocket bodies already orbit Earth. A recent uncontrolled upper stage impact on the moon highlights long-lived debris. Governments and companies may push regulation and more cleanup missions next.
