Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what assessment her Department has made of the potential impact of satellite debris falling to earth on the environment.

The UK Space Agency has led global research on the potential environmental impact of satellites burning up in Earth’s atmosphere (atmospheric ablation) through a set of short, complementary research studies. Initial outcomes conclude there is an impact of metals on the atmosphere, but further research is needed to fully identify knowledge gaps and provide a solid evidence base for decision-making.

The Space Industry Act (2018) requires applicants for launch operator and spaceport licences to provide the UK Civil Aviation Authority (CAA) with an assessment of the effects that launches of spacecraft are expected to have on the environment.

The National Space Operations Centre monitors all trackable space objects and provides indicators and warnings of re-entry and projected paths, particularly where objects are expected to have sufficient mass and volume for some or all components to survive to the surface.
