Recent analyses warn that the rapid expansion of satellite constellations—such as Starlink and similar projects—may heavily disrupt future orbital telescopes. While ground-based observatories have faced challenges from satellite debris, the impact on space telescopes was previously considered minimal. However, new projections show that upcoming missions could be overwhelmed by satellite trails, with some detectors recording nearly 100 satellite crossings in a single exposure.

Ironically, measures intended to reduce the impact on ground telescopes might worsen the situation for satellites in orbit. Efforts to minimize light pollution and satellite visibility often involve modifications that could increase interference for space-based instruments.

Satellite Constellations vs. Space Astronomy

The threat from satellite networks is a recent concern. Before the advent of reusable rockets lowered launch costs, orbiting constellations were limited, comprising only a few dozen satellites. Today, mega-constellations like Starlink are transforming the orbital environment, posing significant challenges for astronomers trying to capture clear cosmic images.

Experts emphasize the need for international regulation and technological solutions to balance satellite deployment with the preservation of space-based scientific research.
