The threat posed by Elon Musk's satellites also affects space telescopes like Hubble

"First came some curious lights in the sky after nightfall, which surprised astronomy enthusiasts. The most excited about the new phenomenon caused by Elon Musk's Starlink satellite network encouraged everyone to go out and watch the spectacle of the luminous trains created by these satellites as they ascended. Then came the protests from astronomers, who saw how those lights ruined images from their telescopes, streaking them with intense white lines."

"Now, a NASA study warns that not even space telescopes like Hubble will be safe from the threat that satellite constellations pose to astronomy. The new research, led by Spanish astrophysicist Alejandro Serrano Borlaff, shows that at least one in three Hubble images will be contaminated by satellite light if the projects planned for the next decade for large constellations like Starlink are completed."

Predictions indicate that 96% of ARRAKIHS images will be contaminated by sunlight reflected from more than 500,000 planned satellites from Starlink and other megaconstellations. Early public reaction included excitement over luminous trains created by ascending satellites, followed by astronomers' protests as streaking white lines ruined ground-based telescope images. Promised technical improvements by Starlink were never fully implemented, and companies urged expansion to space-based observatories. Contamination will affect space telescopes: at least one in three Hubble images are expected to be compromised, with even worse consequences for newly launching next-generation space telescopes.
