Satellites

Question: To ask the Secretary of State for Business, Innovation, Science and Trade, what assessment the Department has made of the potential impact of orbital mirror constellations on astronomical observation and light pollution in the UK, and whether the Government is taking any steps, through international space regulatory bodies, to establish light-reflection limits for Low Earth Orbit satellites.

Answer: The UK Government has funded three studies to date and engages internationally through a range of fora, including the United Nations Committee on the Peaceful Uses of Outer Space, to help develop guidelines and governance structures that meet the needs of the modern space age. This work includes international engagement on matters such as sustainability and the protection of dark and quiet skies for astronomy and scientific observation.
