“All aluminum is coated with a surface oxide, and until now we did not know what the structure of this native oxide layer on the nanoparticles was. This has been a limiting factor preventing the ...

Not only was the gallium dissolving the aluminum oxide, it was also causing the aluminum to separate into nanoparticles, and keeping them separate. “The gallium separates the nanoparticles and ...

A 550-pound satellite will release about 66 pounds of aluminum oxide nanoparticles during reentry. Starlink’s satellites have grown heavier over time, with the latest version weighing in at ...

of aluminum oxide nanoparticles (1-100 nanometers in size) during its reentry plunge. Most of these particles are created in the mesosphere, 50-85 kilometers (30-50 miles) above Earth's surface.

In 2022, 18.7 tons of aluminum oxide nanoparticles were released into the atmosphere by falling satellites, they said. Looking ahead to planned satellite launches, this could increase to as much ...
