SpaceX’s Falcon Heavy launch imminent as Elon Musk unveils first photos
For the first time in SpaceX’s history, the company is close enough to the inaugural launch of its massive Falcon Heavy rocket that the vast majority of the vehicle is already at Cape Canaveral, FL, and all three of its first stages have been mated together.

We know this because Elon Musk took to Instagram and Twitter last night and posted the first-ever real-life photos of the launch vehicle, currently stationed at the Horizaontal Integration Facility (HIF) at SpaceX’s LC-39A launch pad.
At launch, Falcon Heavy will only be surpassed in thrust and payload by the megarockets of the 1960s, the US Saturn V and the Soviet N-1. Best described by an eager employee, Falcon Heavy will have the same thrust as fifteen 747 Jumbo Jets at full throttle, and could nearly carry a fully-loaded 737 passenger jet into low Earth orbit (LEO) in a fully expendable configuration.
Over the past several weeks of inactivity, SpaceX’s pad technicians have been hard at work modifying the LC-39A launch pad and its Transporter/Erector/Launcher (TEL) to support the inaugural launch of Falcon Heavy. This mainly involved considerably upgrading the water deluge system used to muzzle the impact of the sheer sound created at launch, but also required the addition of four more hold-down clamps, necessary to abort a launch after engine ignition. An additional array of communications wiring and umbilical connections for fueling have also likely been added to the TEL in order to support the requirements of what are essentially three simultaneous Falcon 9 launches.

A lack of frenetic activity at the pad in the last handful of days suggests that those modifications are nearly complete, and SpaceX fans and followers are now eagerly awaiting the rollback of the TEL to 39A’s integration facilities, where Falcon Heavy will soon after be integrated with the TEL for the first time ever. After this milestones, we can expected Falcon Heavy to be rolled out the pad for what is known as a wet dress rehearsal (WDR), akin to a launch or static fire but without any engine ignition. It’s possible that a bug-free WDR could fluidly transition into the first static fire for the vehicle, but it is probable that SpaceX will take a more cautious approach with this launch campaign. Following the successful completion of the WDR and static fire, Falcon Heavy’s inaugural launch will be imminent. We are potentially no more than 40 days out, the closest SpaceX has ever been to a Falcon Heavy launch.
Of note, the final picture posted by Musk offers an absolutely stunning view of the vehicle’s business end, showing off its 27 Merlin 1D engines and revealing quite obviously that both of Falcon Heavy’s side cores are flight-proven, whereas the center core is new. The photos provided also offer a glimpse of the only component clearly missing, the second stage and its mysterious Tesla Roadster payload. Unconfirmed whispers in the fan community have it on good authority that the Roadster has in fact already been mated to the second stage’s payload adapter, and transport to the Cape and integration with the full Falcon Heavy stack are undoubtedly imminent.

Possibly most significant of all, Musk suggested that the Roadster payload would be sent on a course to Mars, although it has yet to be concluded whether that will be in the form of a general orbit similar to Mars or an actual trans-Martian injection culminating in an orbit around the Red Planet. The former is far more likely, but the latter would be an extraordinarily impressive test of SpaceX hardware in deep space, a necessary precursor for the company’s goals of interplanetary colonization. Time will tell, and in the meantime we can expect a veritable flood of rocket and payload photos as SpaceX rapidly approaches a historic moment for the company.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo
“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.
NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance.
More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system.
Jensen Huang’s praise for Tesla FSD
Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”
During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:
“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.
“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said.
Nvidia’s platform approach vs Tesla’s integration
Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.
“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.
He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.
“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”
He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.

xAI’s turbine deal details
News of xAI’s new turbines was shared on social media platform X, with user @SemiAnalysis_ stating that the turbines were produced by South Korea’s Doosan Enerbility. As noted in an Asian Business Daily report, Doosan Enerbility announced last October that it signed a contract to supply two 380 MW gas turbines for a major U.S. tech company. Doosan later noted in December that it secured an order for three more 380 MW gas turbines.
As per the X user, the gas turbines would power an additional 600,000+ GB200 NVL72 equivalent size cluster. This should make xAI’s facilities among the largest in the world. In a reply, Elon Musk confirmed that xAI did purchase the turbines. “True,” Musk wrote in a post on X.
xAI’s ambitions
Recent reports have indicated that xAI closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development. The funding, as per the AI startup, “will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products.”
The company also teased the rollout of its upcoming frontier AI model. “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote in a post on its website.
