SpaceX begins stacking Florida Starship launch tower
SpaceX has begun stacking Starship’s first Florida launch tower.
Less than half a year after the company restarted work on a Starship launch pad located just a few hundred feet away from existing Falcon launch facilities at NASA’s Kennedy Space Center (KSC) LC-39A pad, a massive new launch tower has begun to take shape. Once it reaches its final height, that tower will become the second tallest rocket-related structure (excluding lightning towers) on the East Coast, only beaten by NASA’s iconic Vehicle Assembly Building (VAB).
It could reach that height far sooner than later.
For Starship’s Pad 39A facilities, SpaceX faces the unique challenge of organizing a major construction operation at one of the busiest and most important active launch sites in the US. In just the first half of 2022, LC-39A is on track to support 10 Falcon 9 launches, imposing unique constraints on adjacent Starship pad construction. In a partial response to those challenges, as previously discussed on Teslarati, SpaceX has taken lessons learned from Starbase, Texas and optimized the assembly process of a number of pad components to limit the amount of work that will need to be done at the pad itself.
For the first launch tower, SpaceX and its contractors moved exceptionally quickly and took just over three months after work on the first prefabricated section began to stack the structure to its full height of ~146 meters (~480 ft). Each of the nine sections was essentially bare, however, reducing the amount of pre-stack work but drastically complicating and increasing the amount of post-stack work required to turn the tower into something useful. For Florida’s first Starship launch tower, SpaceX has spent more than three months assembling and meticulously outfitting the first six of nine prefabricated tower sections before the first stack.
The sections SpaceX began stacking on June 21st already have a variety of railings, elevator shafts, doorways, walkways, hardpoints, plumbing, and more preinstalled. While each section and all abbreviated plumbing and hardware will need to be connected after each stack, that process should be far easier and faster than the methods SpaceX used in South Texas. Offsite, SpaceX is also making excellent progress assembing the pad’s donut-like orbital launch mount and parts of the three giant arms that will eventually attach to Starship’s first Florida launch tower – two for lifting and catching rockets and a third for stabilizing and fueling Starship.
Much like the tower segments, there’s a good chance that those other Floridan components will be closer to completion than their Texas siblings were when they eventually head to the launch pad for installation. Additionally, if SpaceX’s experience in Texas is representative, Starship’s first Florida launch tower could reach its full height just a few months from now.
For the tower to be truly complete, SpaceX will need to finish and install three arms, and connect one of those arms to ground supplies of Starship gases and propellant located at Pad 39A. Because 39A has never needed methane, Starship’s fuel of choice, that step will also require the installation and activation of a new tank farm and plumbing capable of storing, rapidly ‘subcooling,’ and distributing at least a thousand tons (~2.2M lb) of liquid methane (LCH4). Starbase Florida is making great progress but a large amount of work still stands between SpaceX and launch readiness.

Elon Musk and Tesla AI Director share insights after empty driver seat Robotaxi rides
The executives’ unoccupied tests hint at the rapid progress of Tesla’s unsupervised Robotaxi efforts.
Tesla CEO Elon Musk and AI Director Ashok Elluswamy celebrated Christmas Eve by sharing personal experiences with Robotaxi vehicles that had no safety monitor or occupant in the driver’s seat. Musk described the system’s “perfect driving” around Austin, while Elluswamy posted video from the back seat, calling it “an amazing experience.”

Elon and Ashok’s firsthand Robotaxi insights
Prior to Musk and the Tesla AI Director’s posts, sightings of unmanned Teslas navigating public roads were widely shared on social media. One such vehicle was spotted in Austin, Texas, which Elon Musk acknowleged by stating that “Testing is underway with no occupants in the car.”
Based on his Christmas Eve post, Musk seemed to have tested an unmanned Tesla himself. “A Tesla with no safety monitor in the car and me sitting in the passenger seat took me all around Austin on Sunday with perfect driving,” Musk wrote in his post.
Elluswamy responded with a 2-minute video showing himself in the rear of an unmanned Tesla. The video featured the vehicle’s empty front seats, as well as its smooth handling through real-world traffic. He captioned his video with the words, “It’s an amazing experience!”
Towards Unsupervised operations
During an xAI Hackathon earlier this month, Elon Musk mentioned that Tesla owed be removing Safety Monitors from its Robotaxis in Austin in just three weeks. “Unsupervised is pretty much solved at this point. So there will be Tesla Robotaxis operating in Austin with no one in them. Not even anyone in the passenger seat in about three weeks,” he said. Musk echoed similar estimates at the 2025 Annual Shareholder Meeting and the Q3 2025 earnings call.
Considering the insights that were posted Musk and Elluswamy, it does appear that Tesla is working hard towards operating its Robotaxis with no safety monitors. This is quite impressive considering that the service was launched just earlier this year.

Starlink passes 9 million active customers just weeks after hitting 8 million
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
SpaceX’s Starlink satellite internet service has continued its rapid global expansion, surpassing 9 million active customers just weeks after crossing the 8 million mark.
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
9 million customers
In a post on X, SpaceX stated that Starlink now serves over 9 million active users across 155 countries, territories, and markets. The company reached 8 million customers in early November, meaning it added roughly 1 million subscribers in under seven weeks, or about 21,275 new users on average per day.
“Starlink is connecting more than 9M active customers with high-speed internet across 155 countries, territories, and many other markets,” Starlink wrote in a post on its official X account. SpaceX President Gwynne Shotwell also celebrated the milestone on X. “A huge thank you to all of our customers and congrats to the Starlink team for such an incredible product,” she wrote.
That growth rate reflects both rising demand for broadband in underserved regions and Starlink’s expanding satellite constellation, which now includes more than 9,000 low-Earth-orbit satellites designed to deliver high-speed, low-latency internet worldwide.
Starlink’s momentum
Starlink’s momentum has been building up. SpaceX reported 4.6 million Starlink customers in December 2024, followed by 7 million by August 2025, and 8 million customers in November. Independent data also suggests Starlink usage is rising sharply, with Cloudflare reporting that global web traffic from Starlink users more than doubled in 2025, as noted in an Insider report.
Starlink’s momentum is increasingly tied to SpaceX’s broader financial outlook. Elon Musk has said the satellite network is “by far” the company’s largest revenue driver, and reports suggest SpaceX may be positioning itself for an initial public offering as soon as next year, with valuations estimated as high as $1.5 trillion. Musk has also suggested in the past that Starlink could have its own IPO in the future.

NVIDIA Director of Robotics: Tesla FSD v14 is the first AI to pass the “Physical Turing Test”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine.
NVIDIA Director of Robotics Jim Fan has praised Tesla’s Full Self-Driving (Supervised) v14 as the first AI to pass what he described as a “Physical Turing Test.”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine. And just like smartphones today, removing it now would “actively hurt.”
Jim Fan’s hands-on FSD v14 impressions
Fan, a leading researcher in embodied AI who is currently solving Physical AI at NVIDIA and spearheading the company’s Project GR00T initiative, noted that he actually was late to the Tesla game. He was, however, one of the first to try out FSD v14.
“I was very late to own a Tesla but among the earliest to try out FSD v14. It’s perhaps the first time I experience an AI that passes the Physical Turing Test: after a long day at work, you press a button, lay back, and couldn’t tell if a neural net or a human drove you home,” Fan wrote in a post on X.
Fan added: “Despite knowing exactly how robot learning works, I still find it magical watching the steering wheel turn by itself. First it feels surreal, next it becomes routine. Then, like the smartphone, taking it away actively hurts. This is how humanity gets rewired and glued to god-like technologies.”
The Physical Turing Test
The original Turing Test was conceived by Alan Turing in 1950, and it was aimed at determining if a machine could exhibit behavior that is equivalent to or indistinguishable from a human. By focusing on text-based conversations, the original Turing Test set a high bar for natural language processing and machine learning.
This test has been passed by today’s large language models. However, the capability to converse in a humanlike manner is a completely different challenge from performing real-world problem-solving or physical interactions. Thus, Fan introduced the Physical Turing Test, which challenges AI systems to demonstrate intelligence through physical actions.
Based on Fan’s comments, Tesla has demonstrated these intelligent physical actions with FSD v14. Elon Musk agreed with the NVIDIA executive, stating in a post on X that with FSD v14, “you can sense the sentience maturing.” Musk also praised Tesla AI, calling it the best “real-world AI” today.
