Satellites: Adverse Effects on Astronomy

Lord Clement-Jones Excerpts

Wednesday 20th November 2024 Lords Chamber

[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.

[Lord Clement-Jones (LD)]

My Lords, in that National Space Strategy, the previous Government focused on encouraging lower earth orbit satellites, which are increasingly contributing to the loss of dark skies, as we have heard. Will this Government focus on incentives for the development of higher-orbit satellites, such as geostationary satellites, particularly the micro versions, of which far fewer are needed? They offer the best cost economics, compared to LEO systems, and have a lower impact on the night sky.

[Lord Vallance of Balham (Lab)]

The noble Lord makes an extremely important point about the size of satellites, which is one of the problems with the interference from both radio and optical imaging. The smaller satellites, which the UK is extremely good at making, will become an increasing part of the solution. On orbit, we have a commitment to low orbit through the OneWeb approach—where there are about 700 in low orbit—and to higher orbit where it is appropriate to do so.
