I wonder is this burning-up satellite story will have any environmental impact. See what you think.
"Every 16 hours, more or less, a Starlink satellite falls out of the sky. It's part of the SpaceX business model: Old obsolete satellites re-enter to make way for newer models.
So far this year, 171 Starlinks have reentered, adding more than 5 metric tons of aluminum oxide to the stratosphere and mesosphere. How does this compare to natural sources?

The primary natural source is meteoroids -- the same "shooting stars" that streak across the night sky. As they burn up between roughly 75 and 110 km, they release a faint dusting of metals. Recent studies suggest that meteoroids disperse between 40,000 kg and 58,000 kg of Al₂O₃ into the atmosphere each year. Starlink in 2026 is on track to add between 26% and 39% of that natural total."
