In the story by the Daily Mail about SpaceX’s Starlink project, there is a debate about how we as humans should use out space. The specific debate about Starlink is that Starlink hampers the ability of people on earth to see natural constellations, but there are further debates on the use of outer space.
Currently, the only regulation on what cannot be done in outer space is the Outer Space Treaty(Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies) signed in 1967. It prohibits the placement of weapons of mass destruction in outer space and that no nation can claim sovereignty over outer space or any celestial body.
Personally, I think that the Outer Space Treaty should be expanded to include some provisions that apply to Antarctica by the Antarctic Treaty System, which include a ban on all military activity, and freedom of navigation. What we also need is a system to dispose of human material in outer space once it is decommissioned, because our current system is to just blast satellites to higher orbits.
Outer space has always been free to all mankind(and possibly other organisms as well), and should remain so.
