Satellite Reflections Threaten Space Telescope Imaging Quality

Reflections from an increasing number of satellites in orbit are threatening the quality of images captured by space telescopes. A recent study led by NASA predicts that over 95% of images taken by some space telescopes could be compromised by satellite streaks in the next decade.

The study highlighted that more than 10,000 active satellites are currently in orbit, with SpaceX alone operating over 7,800 Starlink satellites. The Hubble Space Telescope has already shown signs of this issue, where about 4% of its images experienced light streaks from satellites between 2018 and 2021.

This number is expected to rise significantly, with predictions suggesting that one in three Hubble images could be affected. New telescopes like NASA's SPHEREx, the European Space Agency's ARRAKIHS, and China's Xuntian Space Telescope are projected to experience up to 96% of their images contaminated by satellite reflections.

The American Astronomical Society has raised concerns over the implications of this satellite boom on astronomical observations, pushing for collaborative efforts with federal agencies and satellite companies to mitigate these impacts.

SpaceX has claimed to be taking steps to reduce the light pollution caused by its satellites, such as testing darker coatings and adding visors. The International Telecommunication Union has echoed these concerns, advocating for stricter regulations on satellite launches to ensure the sustainability of space for future astronomical research.
