Can Satellite Mega-Constellations Justify their Impact on Astronomy?

TL;DR

This paper examines whether the benefits of satellite mega-constellations for internet connectivity can outweigh their negative impacts on astronomical observations and science.

Contribution

It provides a critical analysis of the potential scientific impacts of satellite mega-constellations and discusses whether their advantages justify the consequences for astronomy.

Findings

Satellite mega-constellations significantly affect astronomical observations.

The impact depends on constellation design and mitigation strategies.

The paper questions if the scientific benefits can justify the impact.

Abstract

Private space companies are increasingly commercializing near-earth space. Some estimates show that more than 100,000 satellites may orbit the Earth by 2030. This increase in the number of satellites has many consequences for science, particularly astronomy. Satellite mega-constellations for satellite Internet connectivity are one of the main drivers behind the explosion in the number of satellites. Here, we briefly note whether such satellite mega-constellations can justify their impact on astronomy.
