SpaceX announced this week that it will voluntarily bring down about 100 of its first-generation Starlink satellites, which provide broadband Internet from low-Earth orbit, as part of its commitment to “space sustainability.”

The satellites are presently operational and serving Internet customers. However, in a statement, the company said, “The Starlink team identified a common issue in this small population of satellites that could increase the probability of failure in the future.”

This only represents a small fraction of the Starlink megaconstellation, which SpaceX has been launching on Falcon 9 rockets over the last half-decade. To date, SpaceX has put nearly 6,000 satellites into orbit a few hundred kilometers above the planet. This rapid growth in the company’s constellation has raised widespread concerns about the cluttering of low-Earth orbit and the potential for a profusion of debris.
