SpaceX loses dozens of new Starlink satellites to “geomagnetic storm”

Published

SpaceX says that dozens of the 49 Starlink satellites aboard its most recent Starlink launch may have been doomed by a “geomagnetic storm” that arrived the day after.

In an update published on SpaceX.com, the company revealed that “up to 40 of the [49 Starlink V1.5] satellites [launched on February 3rd] will reenter or already have reentered the Earth’s atmosphere” after the “severity of the storm caused atmospheric drag to increase up to 50 percent higher” relative to past Starlink launches. The incident is likely the first time in spaceflight history that a geomagnetic storm – solar weather – has caused satellites to fail because of its effects on Earth’s atmosphere.

There’s some ambiguity in SpaceX’s statement as to how exactly the storm caused up to 40 Starlink satellites to fail or if those satellites actually failed, per se. According to SpaceX, a geomagnetic storm that began on February 4th caused “the atmosphere to warm and atmospheric density at [the mission’s] low deployment altitudes to increase [up to 50%],” thereby increasing the drag on each Starlink satellite by the same amount. SpaceX intentionally launches almost every batch of Starlink satellites to very low parking orbits with perigees (the point of the orbit closest to Earth) around 200 kilometers (125 mi).

At that altitude, both Falcon 9’s upper stage and malfunctioning Starlink satellites will naturally reenter Earth’s atmosphere in a matter of weeks or even days, thus guaranteeing that satellites that fail early on won’t become space debris. Only the Starlink satellites that pass initial testing in orbit are allowed to raise themselves to operational orbits around 550 kilometers (340 mi), where a failed satellite will instead take years to deorbit. Just 500 kilometers higher, natural decay takes decades or even centuries.

For Starlink 4-7, it’s ambiguous if the radiation environment created by the geomagnetic storm or days of exposure to the edge of the atmosphere actually damaged dozens of Starlink satellites beyond recovery or if they simply deorbited so quickly in the unusual environment that they fell past the point of no return. In the latter scenario, the incident is effectively an unforeseen fluke of nature – especially given that three-dozen other Starlink launches have run into no such issues in the last three years. In the fluke-of-nature scenario, it’s also unclear if SpaceX could have predicted – and thus prevented – the anomaly.

SpaceX says it “commanded the satellites into a safe-mode where they would fly edge-on (like a sheet of paper) to minimize drag” as soon as it was aware of the issue but that “the increased drag…prevented the satellites from leaving safe-mode to begin orbit raising maneuvers.” Based on that phrasing, the most obvious explanation is that the added drag caused up to 40 of the satellites to fall far enough into the atmosphere that their ion thrusters would no longer be able to raise their orbits faster than the drag was lowering them. Raising their solar arrays into the position needed for maximum power generation (and thus maximum sustained thrust) would also drastically accelerate reentry.

The 40 satellites SpaceX believes will be lost likely cost the company anywhere from $10 million to $40 million to build, making for a very expensive lesson. The anomaly also means that SpaceX will likely need to factor in yet another weather condition – geomagnetic storms – into Starlink launch planning. If a bit more time could have saved Starlink 4-7, it’s possible that the company will also consider slightly raising the low parking orbits used for Starlink, trading slightly slower natural reentries to reduce the risk of losing dozens of brand new satellites again.

Tesla’s Supercharger network is proving to be a key factor in the company’s dominance in several key markets. These include Norway, which has become a place of strength for the new Model Y. 

This was hinted at by Tesla’s Director of Charging, Max de Zegher, on social media platform X.

Supercharger network sets the industry standard

As noted by the Tesla executive, the Model Y accounted for 29% of all vehicle sales in Norway in September. Part of the vehicle’s success was likely due to the reliability of the Supercharger Network, which is class leading even in Norway, where 98% of new cars sold are electric.

De Zegher emphasized on X that Tesla Superchargers are still in a class of their own. An EPSI survey of nearly 1,500 Norwegian EV drivers supported his claim, as Tesla Superchargers retained first place in customer satisfaction for the fifth consecutive year. 

Respondents to the EPSI survey praised the Supercharger network’s strong uptime, abundant capacity, and user-friendly digital solutions, placing it ahead of other operators such as Uno-X. Survey researchers highlighted that Tesla has set the standard when it comes to simplicity in the charging process.

Drivers also cited competitive pricing and seamless plug-and-charge functionality as major reasons they prefer Tesla’s network, especially in Norway’s extreme winter conditions where reliability is critical.

Superchargers for everyone

As Norway approaches full EV adoption, network dependability has become a decisive factor in the electric vehicle ownership experience. What is especially notable is the fact that Tesla Superchargers are open to all EVs in Norway, making the network beneficial for everyone.

De Zegher also noted that despite the company’s progress in Norway, Tesla will continue to learn from Norwegian customers so service could be improved further. “We’re always learning from our Norwegian customers. Plug & charge should be the way all customers pay for charging. Extreme cold makes that further obvious,” he wrote.

Tesla Senior Vice President for Automotive Tom Zhu, a key executive behind the company’s success in China and Giga Texas, recently highlighted the “prime directive” of Full Self-Driving (FSD).

Zhu’s comments emphasize Tesla’s uncompromising focus on safety, which has made the company’s vehicles among the safest on the road.

Echoing Musk’s vision for safe autonomous driving

Zhu’s post quoted Musk’s statement from 2021, where the CEO reportedly stated that FSD must avoid accidents even if the most ridiculous events happened in the middle of the road. Zhu stated that beyond everything, Tesla’s systems like Autopilot and FSD are designed to keep passengers safe.

“Elon said it in 2021: “For self-driving, even if the road is painted completely wrong and a UFO lands in the middle of the road, the car still cannot crash and still needs to do the right thing. The prime directive for the autopilot system is: Don’t crash. That really overrides everything. No matter what the lines say or how the road is done, the thing that needs to happen is minimizing the probability of impact while getting you to your destination conveniently and comfortably,” Zhu stated.

“The prime directive, the absolute priority, is to minimize the probability of injury to yourself or to anyone on the road, to pedestrians, or anything like that. It can’t be dependent on the road markings being correct.”

Tesla leadership rallies behind global FSD rollout

Tom Zhu, who previously led Tesla China through its record-breaking growth phase, now oversees automotive operations worldwide. He has reportedly become a problem solver for Elon Musk over the years, with previous reports stating that he was brought in to help Giga Texas optimize its vehicle production ramp.

Zhu’s comments may sound ambitious, but FSD has proven that it values safety above all else over the years. This was highlighted recently in an incident in Australia, when a Model Y was hit by what could very well be a meteor. Despite the impact and part of its windshield melting, the vehicle was able to drive safely and keep its passengers safe.

Elon Musk’s biggest tech rival just canceled his reservation for a Tesla Roadster, the supercar the company has been developing for nearly eight years.

Sam Altman, the CEO of OpenAI, announced on X on Thursday evening that he canceled his Tesla Roadster reservation, or at least is trying to:

Altman placed his Tesla Roadster reservation with a $50,000 deposit way back on July 11, 2018. However, he recently decided that he had waited long enough and decided to email the company to officially cancel the order.

“Hi, I’d like to cancel my reservation. Could you please refund me the $50k?” Altman emails to reservations@tesla.com.

He then received an immediate response, but not from Tesla. Instead, it was a bounce-back message from Google, stating that the message could not be delivered to the email because it was not active.

Altman then provided a reason for his cancellation, and it was not related to the intense rivalry he had with Elon Musk:

“I really was excited for the car! And I understand delays. But 7.5 years has felt like a long time to wait.”

Altman and Musk have a lengthy history with one another that dates back to 2015, when OpenAI was created. The feud has resulted in lawsuits over breaching founding agreements by prioritizing profits.

Musk has been especially critical in recent years because of Altman’s decision to turn OpenAI into a for-profit business that he says is “built on a lie.”

This year, Musk offered over $97 billion to buy OpenAI, and a judge blocked his request to stop the company from being converted into a for-profit in March.

OpenAI then countersued Musk in April, while xAI, Musk’s company, sued OpenAI for allegedly stealing secrets through poached employees in September.

Regarding the Roadster, Tesla has been developing it for several years and has delayed its release for five consecutive years. The company says it will have a demo of what it has changed since it was unveiled in 2017 later this year, but no date has been set quite yet.
