After rejection a year ago, the Scientific and Technical subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) has agreed to add the issue of satellite constellations as an agenda item for further discussion. It will be addressed as ‘Dark and Quiet Skies, astronomy and large constellations: addressing emerging issues…
