SpaceX is attacking an FAA report for claiming Starlink risks creating dangerous falling debris that could slam back into the planet.
According to SpaceNews, the company sent a letter to the Department of Transportation on Monday, criticizing an FAA report sent to Congress about the potential hazards of disposing satellites from large constellations.
In SpaceX’s case, the company’s satellites are designed to completely burn up in our planet’s atmosphere once they’ve been set to retire. Still, the FAA report says it “would be worthwhile to definitively evaluate if any debris” from a SpaceX craft such as Starlink might survive atmospheric reentry.
If no debris survives reentry, then any disposed Starlink satellites should pose no risk, the FAA says. But if some debris does remain intact during atmosphere reentry, the agency says the plummeting Starlink fragments could pose a public danger.
“By 2035, if the expected large constellation growth is realized and debris from Starlink satellites survive reentry, the total number of hazardous fragments surviving reentries each year is expected to reach 28,000,” the report concludes. This could lead to one person being killed every two years or potentially more if the falling debris hits an aircraft, the FAA adds.
Although the agency’s risk assessment is theoretical, SpaceX is taking issue with how the FAA’s report could mislead Congress members about Starlink, which currently spans over 4,800 active satellites.
“To be clear, SpaceX’s satellites are designed and built to fully demise during atmospheric reentry during disposal at end of life, and they do so,” the company wrote in the letter, which was posted by Ars Technica. “Extensive engineering analysis and real-world operational experience verify this basic fact,” the company added.
To develop its report to Congress, the FAA contracted a nonprofit called Aerospace Corporation to help it assess the risks of large satellite constellations. However, SpaceX claims the Aerospace Corp. used a “flawed methodology” and old information from NASA to make its assessment. The nonprofit also apparently never reached out to SpaceX for more information about its own satellites.
“Instead, Aerospace chose to base its evaluation on assumptions, guesswork and outdated studies relating to satellite constellations developed decades ago,” the company added. As a result, SpaceX is asking the FAA to correct its report to Congress.
In response, the FAA told PCMag it’s currently reviewing the SpaceX's letter to the Department of Transportation.
SpaceX didn’t immediately respond to a request for comment. But it's not the first time the company has defended Starlink from orbital hazard concerns. Last year, SpaceX did the

The release date for the slimmer and lighter mid-gen refresh of the PS5 has seemingly leaked online, alongside details about its first bundle. As per reliable tipster Billbil-kun — notorious for accurately leaking monthly PS Plus games ahead of time — the new PlayStation consoles with smaller form factor will go on sale November 10 in the US before spreading out to other regions; both disc and digital versions. A bit before that, on November 8, Sony would be bundling it with the newly launched Marvel's Spider-Man 2 at $559.99, which is the same amount as the existing standard edition bundle. While not explicitly mentioned, the content should be the same, with a digital voucher for the game, alongside a themed controller.
