The Federal Communications Fee simply gave Starlink the inexperienced mild to vastly increase its mega-constellation of satellites, which might doubtlessly deliver thousands and thousands of Individuals sooner web. However the scientists I spoke with are sounding the alarm, saying that 7,500 extra satellites in uncharted orbits might have wide-ranging penalties, together with negatively affecting Earth’s ambiance.
This approval for the deployment of extra Starlink satellites was by no means actually doubtful — Trump’s FCC has persistently sided with Elon Musk’s SpaceX — despite the fact that it was simply half the variety of satellites the corporate initially requested.
“I am happy to see the FCC didn’t simply go, ‘Have as many as you need,’” Jonathan McDowell, an astrophysicist who tracks satellite tv for pc launches. “The FCC is continuing at the least considerably intentionally, though I nonetheless have considerations in regards to the environmental affect of those constellations.”
The authorization will practically double the variety of Starlink satellites in orbit to fifteen,000 by 2031, raising familiar distress from scientists in regards to the danger of collisions in an more and more crowded stratosphere, in addition to overreliance on satellite tv for pc communications.
“This can be a lot of satellites, nevertheless it’s solely the start,” McDowell stated. “They will ask for extra. China will throw rather a lot up. Different corporations and international locations will throw stuff up. We’ll move the 100,000 mark most probably.”
Whereas there are at the moment about 40,000 objects in space tracked by house surveillance networks like NASA and the European Area Company, there are numerous extra that aren’t tracked. The variety of objects in house able to inflicting “catastrophic harm” is estimated to be over 1.2 million.
“The problem will not be the massive objects we hold monitor of. The problem is at all times the sub-10 centimeter objects that we do not hold monitor of,” Vishnu Reddy, a professor of planetary science on the College of Arizona, informed CNET.
FCC applauds order
FCC Chair Brendan Carr stated in an announcement that the authorization of extra Starlink satellites was a “sport changer for enabling next-generation companies,” touting the advantages to the American financial system and broadband connections nationwide.
“President Trump is restoring America’s know-how management,” Carr stated. “By authorizing 15,000 new and superior satellites, the FCC has given SpaceX the inexperienced mild to ship unprecedented satellite tv for pc broadband capabilities, strengthen competitors, and assist be certain that no neighborhood is left behind.”
Buried within the actual order is much extra measured language: “Whereas SpaceX requests motion on its complete proposed 29,988-satellite constellation, we proceed incrementally right here.”
The FCC’s order predicts that the approval will “dramatically enhance companies to clients in America,” even going as far as to say it can ship “pace service, together with symmetrical obtain and add speeds.”
The FCC can also be authorizing SpaceX to maneuver its satellites decrease in orbit, which is predicted to improve latency issues which have dogged Starlink for years, however might make them extra prone to photo voltaic storms.
Starlink gained FCC approval for a further 7,500 V2 satellites.
An more and more crowded orbit
The doomsday state of affairs with all these satellites in movement is the Kessler Syndrome, a hypothetical state of affairs through which particles in house units off a sequence response: One house object crashes into one other, which creates extra particles till Earth’s orbit is so cluttered with house junk that satellites can not function.
To ensure Starlink satellites don’t come into contact with this house particles, SpaceX requires that they maneuver every time the likelihood of a collision is 3 in 10 million. That customary was truly new in Starlink’s July 2025 status report with the FCC; beforehand, it had been 1 in 1 million.
Regardless of that greater threshold, Starlink satellites carried out 144,404 danger mitigation maneuvers within the six-month interval ending in Might 2025, an increase of about 200% from the earlier six months. There have been 148,696 maneuvers in an increase of about 200%.
That’s about one maneuver each 106 seconds, and that’s only for Starlink. The roughly 5,000 different lively payloads at the moment in orbit don’t publicly report the variety of maneuvers they make. This excessive variety of maneuvers is each good and dangerous — they’ve managed to keep away from collisions to date, however the elevated motion makes it more durable for different operators to know the place satellites shall be.
“If everyone on the road is attempting to keep away from getting hit, ultimately, we’ll have accidents,” Reddy informed me in a earlier interview.
This was described as an “orbital home of playing cards” in one recent paper, with researchers estimating that it could take 5.5 days for a catastrophic collision to happen if there have been no maneuvers or a extreme loss in situational consciousness occurred. In 2018, the yr earlier than Starlink launched its first satellites, that quantity was 164 days. (The paper has not been peer-reviewed.)
“What occurs if there is a photo voltaic occasion the place we have misplaced management of the satellites? It will be dangerous,” Reddy stated.
The extra satellites which can be launched, the upper the stakes are. Occasions like a Starlink satellite explosion in December or the breakup of a Chinese rocket body in 2024 all tip the scales a bit extra towards these doomsday situations.
Results on the ambiance
Starlink’s satellites usually final round 5 years. After that, they’re “deorbited,” a pleasant manner of claiming that they’re steered into the Earth’s ambiance to deplete. Since Starlink launched its first satellites in 2019, we haven’t but seen the results at scale.
“We do not perceive the reentry chemistry once they eliminate them, to what extent that is affecting the ambiance,” stated McDowell.
However the early indicators aren’t nice. One 2024 study, funded by NASA and printed in Geophysical Analysis Letters, discovered {that a} 550-pound satellite tv for pc releases about 66 kilos of aluminum oxide nanoparticles throughout reentry. These oxides have elevated eightfold from 2016 to 2022. The Gen2 satellites authorised by the FCC weigh about 1,800 kilos.
“That is primarily a priority for the massive variety of satellites to be launched sooner or later,” Joseph Wang, one of many examine’s authors, told CNET at the time. “We projected a yearly extra of greater than 640% over the pure degree [of aluminum oxide nanoparticles]. Based mostly on that projection, we’re very anxious.”
Samples taken in 2023 by scientists with the Nationwide Oceanic and Atmospheric Administration discovered that about 10% of particle particles within the stratosphere contained traces of metals from rockets and satellites. They estimated this might develop to 50% or extra “primarily based on the variety of satellites being launched into low-Earth orbit.”
What impact that may have continues to be one thing of an open query, however there’s little question that the huge improve in satellites — and their inevitable de-orbiting — will change the composition of the stratosphere considerably.
Photo voltaic storm dangers at decrease orbits
One issue that’s been underdiscussed within the newest FCC approval is the elevated danger of photo voltaic storms wiping out satellites in decrease orbit, based on Sascha Meinrath, professor of telecommunications at Penn State College.
Over the course of 2026, Starlink will decrease 4,400 satellites from 342 miles above the Earth’s floor to 298 miles, according to a Jan. 1 post on X from Michael Nicolls, vice chairman of Starlink engineering at SpaceX. The brand new FCC order authorizes Starlink to maneuver satellites as little as 211 miles.
“I am extra involved simply because we hold shifting them decrease and decrease,” Meinrath informed CNET. “There is a motive why individuals are like, ‘Oh, wow, this has higher statistics for his or her efficiency.’ There is a motive why they’re empty. It is due to the chance.”
The results of photo voltaic storms on satellites in low-Earth orbit can vary from community efficiency degradation to satellite tv for pc deorbiting in excessive circumstances, based on researchers at the University of California, Irvine. Photo voltaic storms can set off atmospheric drag, which prompts Starlink’s satellites to autonomously modify their altitude in response. Neighboring satellites make their very own changes, and it will probably take three to 4 days earlier than they’re stabilized at their authentic positions.
“The self-driving algorithms, optimized for regular operations, might inadvertently amplify storm impacts by triggering chains of orbital changes,” say the UC Irvine researchers.
That is largely a priority for community efficiency, but when we’re more and more counting on satellites to ship important companies, the affect of photo voltaic storms could possibly be extremely critical, Meinrath stated.
“In the identical manner that you’ve got a wireline infrastructure strung up on poles, that you must take note of issues like wind storms or ice storms. Photo voltaic storms are additionally an inevitability,” he stated. “That very actual drawback stays, so far as I can inform from the filings, unaddressed.”
It’s not simply Starlink
Having 15,000 new satellites within the sky is an enormous deal — it’s greater than the variety of lively satellites at the moment in orbit — however Starlink is much from the one entity that’s lively in house.
“The opposite actually vital growth was that China simply filed for an additional 200,000 satellites with the ITU,” stated McDowell, referring to the Worldwide Telecommunication Union, an company throughout the United Nations that facilitates assigning satellite tv for pc orbits.
Some observers are skeptical that the Chinese language authorities will truly attain this huge quantity, describing the submitting as extra of a land-grab than a possible plan. Underneath ITU guidelines, China would have seven years to launch its first satellite tv for pc, then seven extra to finish the constellation.
“SpaceX will not be as massive a priority because the Chinese language constellations, that are worse on nearly all fronts,” McDowell stated.
China at the moment has over 1,300 satellites in orbit, based on a US Space Force fact sheet. Amazon’s Venture Leo, previously referred to as Venture Kuiper, has additionally launched about 200 satellites out of a proposed 3,236.
Extra satellites will enhance connectivity for thousands and thousands
Whereas Starlink is commonly higher than different choices in rural areas, it has nonetheless by no means persistently met the FCC’s definition of broadband internet as 100Mbps obtain and 20Mbps add speeds. It has additionally struggled on the latency entrance, with the latest knowledge from pace take a look at web site Ookla displaying a median lag of 45ms — about 4 instances greater than the average American gets. (Disclosure: Ookla is owned by the identical firm as CNET, Ziff Davis.)
Starlink has an excellent argument that it’s going to reduce latency by shifting satellites decrease. The approval will even tackle its different essential hurdle: capability. An analysis from Penn State College’s X-Lab discovered that Starlink’s satellites can deal with simply 6.66 households per sq. mile earlier than service begins to dip beneath the FCC’s minimal.
“Shifting all these satellites down of their orbital shells will reduce latency, and it’ll permit for added capability,” Meinrath informed CNET. “If you learn between the traces, you are like, ‘Oh, it is a tacit acknowledgement that, the truth is, there are some extreme capability limitations, and so they’re attempting to determine the way to resolve for these.’”
Whereas the considerations about more and more crowded skies need to be taken severely, so do the advantages of a contemporary high-speed web connection. Companies just like the FCC and SAMHSA have even gone so far as to name broadband entry as a “super-determinant” of well being due to the affect it has on training, employment and well being care entry.
Over the previous a number of years, I’ve talked to dozens of individuals dwelling in rural areas who’ve described Starlink as an absolute sport changer for them.
“You deliver a Starlink dish on the market and plug it in. Two minutes later, you’ve got obtained the entire world once more within the palm of your hand,” Eben Hopson, a photographer in Utqiagvik, Alaska, informed me in a previous interview.
It’s not a stretch to say these Starlink connections are life-altering for thousands and thousands of individuals all over the world. However simply because their satellites are floating in house a whole bunch of miles away doesn’t imply there’s no danger for us right here on the bottom.
