Satellites: Adverse Effects on Astronomy

Debate between Lord Lancaster of Kimbolton and Lord Vallance of Balham

Wednesday 20th November 2024 Lords Chamber

[Lord Vallance of Balham (Lab)]

I thank my noble friend for the question. There is a 10% increase, year on year, in light pollution from land, and there is a substantial increase in the problem of radio and light interference from satellites, as my noble friend says. The number of satellites circulating was about 2,000 in 2019, but it is now well over 10,000 and projected to go very much higher. Because of that, we have pushed to get this very item discussed next year by the scientific and technical committee, which is a sub-committee of the Committee on the Peaceful Uses of Outer Space, to try to make sure that there is an international approach to reducing the problem, including mitigation strategies for satellites that will be put up.

[Lord Lancaster of Kimbolton (Con)]

My Lords, the UK space sector is worth over £20 billion and employs about 50,000 people. The UK launched its first space strategy in September 2021, and the noble Viscount may be concerned to learn that the first point of its 10-point plan is to dominate the European satellite industry. Do the Government still support the space strategy published in 2021, or do they intend to review it?

[Lord Vallance of Balham (Lab)]

The cost of launch has come down by something like 95%. The UK remains committed to getting a launch and remains committed to the space strategy as laid out.
