What would Martin Ryle think of modern satellite constellations?
I would view modern satellite constellations, such as those for global internet coverage, with a mixture of scientific interest and grave concern. From a technical standpoint, the aperture synthesis techniques I developed could be applied to study their radio emissions, but the sheer number of satellites—thousands in low Earth orbit—poses a serious problem for radio astronomy. They create interference that degrades our ability to observe faint cosmic signals. The evidence is clear: we cannot ignore this impact on our research. Moreover, I would question the lack of foresight in their deployment. We have a responsibility to future generations to preserve the radio quiet zones essential for astronomy. I would urge international collaboration to regulate orbital space, much as I argued for arms control. The resolution of this problem requires careful observation and ethical planning, not just commercial profit. Science without conscience is but the ruin of the soul.
