SpaceX is continuously deorbiting older Starlink satellites while launching record numbers of replacements into low Earth orbit.<\/figcaption><\/figure>\n\n\n\nReplacements keep coming<\/h2>\n\n\n\n
The replacement pipeline<\/a> is moving even faster.

Researchers are beginning to measure that trail rather than just model it.

A study published in Nature<\/em> in February 2026 went a step further.

One widely cited 2024 modeling study<\/a> estimated that a typical 250-kg. satellite could generate about 30 kg. of aluminum oxide nanoparticles during reentry.
