Could Elon Musk’s megalomania hinder exoplanet research?
ROX MIDDLETON, LIAM SHAW and JOEL HELLEWELL ask whether cluttering the skies with satellites is a good idea

EXOPLANET research seeks to identify and characterise alien planets orbiting other stars.

Since the first exoplanet was confirmed in 1992, thousands of others have been found.

One focus for this research is the characterisation of their atmospheres. Our own atmosphere, the gas layer in which we live, is so intimately linked to the existence of life on Earth that understanding the atmospheres of exoplanets provides crucial evidence to identify other Earth-like planets.

to have 1,600 satellites orbiting by 2024, and nearly 12,000 satellites up in the skies by 2027

We risk losing sight of the universe beyond and perhaps the ambition
to understand our place in it
