A recent NASA-led study warns that reflections from satellites could compromise over 95% of images taken by space telescopes in the next decade. This phenomenon creates visual artifacts known as satellite trajectories, which have already been observed in Hubble Space Telescope images. As of December 2022, there were more than 10,000 active satellites, primarily from SpaceX’s Starlink program, with many more planned for launch.
The study highlights that the increasing satellite presence is expected to hinder telescopes like NASA’s SPHEREx, the European Space Agency’s ARRAKIHS, and China’s Xuantian Space Telescope, predicting that around 96% of their images could be affected. Hubble has already shown a significant rise in image contamination; researchers found that one ray from satellites appears in at least one-third of its images.
Experts express growing concerns about the potential collisions and glare caused by satellite constellations, urging collaboration with federal agencies and the satellite industry to mitigate these impacts. SpaceX has stated it is implementing measures to minimize satellite brightness, while the International Telecommunication Union calls for stricter regulations to ensure the sustainability of space resources.
