What is the business case? Can this be profitable?
A Large OrbitSweeper Cubesat (LOSC =100 kg wet, 20 kg dry, 2000s ISP) is estimated to cost $2M to build, test, launch and operate. While some companies might contract to remove a single object, it is more likely that a companies with large constellations will pay to reduce collision risk in an orbital shell, reducing the need for collision avoidance maneuvers and thus extending the operational life of their satellites. SSO is place to start, as SpaceX Transporter offers low cost launches to this orbital family, and there is a lot of debris here. In the diagram below the combination of Altitude and Inclination label "High ROI Objects" are ones that will cross both Starlink and Kuiper mega constellations.
