U.S. Representative Kevin Kiley (R-CA) has sent a letter to FAA Administrator Michael Whitaker over his recent claims about SpaceX. During Tuesday’s Transportation Committee hearing, Whitaker advanced several alleged safety concerns about SpaceX’s operations, all of which were strongly denied by the private space company.
During his testimony, the FAA Administrator alleged that SpaceX must operate at the highest level of safety, which includes having a safety management system program and a whistleblower program. He also alleged that SpaceX had launched without a permit last year in Cape Canaveral, FL and that the delay in Starship’s Flight 5 launch was due to SpaceX failing to provide an updated sonic boom analysis, among other safety concerns.
FAA Administrator Whitaker made several incorrect statements today regarding SpaceX. In fact, every statement he made was incorrect.
It is deeply concerning that the Administrator does not appear to have accurate information immediately available to him with respect to SpaceX… pic.twitter.com/OrtMUvnCNI— SpaceX (@SpaceX) September 24, 2024
SpaceX strongly denied each of Whitaker’s claims. In a letter, Mat Dunn, senior director of global government affairs at SpaceX, stated that “every statement (the FAA Administrator) made was incorrect.” Dunn also argued that SpaceX is currently the “safest, most reliable launch provider in the world, and is absolutely committed to safety in all operations.”
Kiley’s recent letter to Whitaker carried some of the points from SpaceX’s rebuttal of the FAA Administrator’s claims. As per the Representative, Whitaker must provide answers to a number of questions surrounding his claims during the Transportation Committee hearing.
FAA Administrator Whitaker made a number of false statements in his testimony about @SpaceX. Either he doesn’t know what’s going on at his agency or he deliberately deceived Congress.
I’ve asked him which it is. Either possibility calls into doubt his fitness to lead the FAA. pic.twitter.com/lW2KcOnItT— Rep. Kevin Kiley (@RepKiley) September 25, 2024
Following is U.S. Representative Kevin Kiley’s letter to FAA Administrator Michael Whitaker.

Washington, DC 20591
Dear Administrator Whitaker,
On September 24, 2024, you testified at a hearing of the Aviation Subcommittee of the House Transportation and Infrastructure Committee. I asked you several questions during that hearing regarding the FAA’s decisions with respect to SpaceX launches. Your answers appear to be filled with inaccurate statements. Such falsehoods raise serious concerns about your fitness to lead the FAA. Please provide my office with responses in writing to the following questions –
- You claimed that SpaceX launched recent Falcon missions without a permit. SpaceX has said these claims are completely false, and that the FAA has not alleged previously that the company was not permitted or licensed to launch these missions. Can you share the evidence for your claim that SpaceX launched these missions without a permit?
- You claimed that SpaceX moved a fuel farm closer to the population without completing a risk analysis statement. SpaceX says that the new location was twice the distance from the nearest publicly accessible area, that the company provided the FAA with all the required analysis, and that the FAA ultimately approved the revised location. Please supply all correspondence between the FAA and SpaceX relative to the fuel farm.
- You claimed that SpaceX failed to provide an updated sonic boom analysis. SpaceX refutes this and says that the Fish and Wildlife Service had already reviewed Starship’s sonic booms and determined they had no environmental impact. While SpaceX has acknowledged it recently provided the FAA data showing a slightly larger sonic boom area than originally anticipated, the company maintains this results in no new environmental impact.
- What evidence does the FAA have of a new environmental impact?
- How long will it take the FAA to make this minor paperwork update?
- What evidence does the FAA have for your assertion that this is a safety related incident”?
- You claimed that SpaceX was in violation of Texas state law. What Texas laws did SpaceX violate?
- Does the FAA need to be reformed to keep up with innovation in the commercial space industry?
From the dawn of the space age, America has set the standard in exploration. Our nation’s spirit of innovation has propelled us to the moon and pushed the boundaries of what’s possible. If we want to keep that legacy alive, we must work with innovators, rather than slow them down. We cannot hinder private industry that is pushing the limits, with regulatory red tape and constant delays. The longer we stall, the more ground we lose. We must continue to empower our private space companies to innovate, build, and lead. This is the only way that we can ensure our national security, while also guaranteeing that America defines the next generation of space exploration. I look forward to your response.
Sincerely,
Kevin Kiley
Member of Congress

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.
