Shortly after Teslarati reported that the first operationalized Raptor had shipped to McGregor, Texas for its first full-scale static fire tests, SpaceX CEO Elon Musk took to Twitter to post the first official photos of the “radically redesigned” engine preparing for its critical debut test fire in Texas.

Designed with extreme reliability, efficiency, and reusability in mind, the Raptor seen in Musk’s photos is rated for just shy of 2.5 times the thrust of Merlin 1D at 200 tons (450,000 lbf) and has been commonized across both stages of BFR (Starship and Super Heavy) to spread out development costs and speed up the next-generation rocket’s orbital launch debut.

Aside from revealing some impressive photos of the first upgraded Raptor preparing for a static fire test, Musk went into a bit more detail on the future of the engine and its probable development path, describing Raptor in its current iteration as a sort of compromise between achieving nominal performance and minimizing the cost and timescale to arrive at a flight-ready engine. Currently stationed at SpaceX’s McGregor, Texas development and testing facilities, Raptor appears to feature an expansion ratio somewhere in between Merlin 1D (optimized for sea-level) and MVac (optimized for vacuum).

This increases the stress on the nozzle during ignition and operation at normal atmospheric pressures but it also improves engine efficiency once Starship (or Super Heavy) rises above the thickest parts of Earth’s atmosphere, even if a medium-expansion nozzle still can’t touch the performance of a giant vacuum-optimized bell like those used by MVac. As such, BFR in its earliest iterations will be significantly less capable than a fully-optimized version of the rocket when it comes to high-energy Earth/lunar orbits and interplanetary trajectories, a challenge that can at least initially be hurdled by accepting much lower nominal payload capabilities and relying on brute-force performance, much like Falcon 9 and Heavy.

Assuming the first hot-fire tests of the full-scale, operationalized Raptors go well, three of the next-gen engines could support the first hop tests of a full-scale Starship prototype sometime in the next few months, potentially as early as late-February or March. Musk also reiterated that Starship’s complimentary booster – known as Super Heavy and set to begin initial prototype assembly as early as April – will feature 31 Raptor engines capable of producing upwards of 12.4 million pounds of thrust (62,000 kN) at liftoff. However, Musk indicated that the sheer value of 31 advanced Raptor engines also means that the first Super Heavy flights may only feature a partial complement of engines in case the vast booster experiences a failure, far from uncommon during the first few launches of a new rocket.

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 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.”

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.

Tesla is burning the midnight oil this Christmas, with the Tesla AI team quietly rolling out Full Self-Driving (Supervised) v14.2.2.1 just a day after FSD v14.2.2 started rolling out to customers. 

Tesla owner shares insights on FSD v14.2.2.1

Longtime Tesla owner and FSD tester @BLKMDL3 shared some insights following several drives with FSD v14.2.2.1 in rainy Los Angeles conditions with standing water and faded lane lines. He reported zero steering hesitation or stutter, confident lane changes, and maneuvers executed with precision that evoked the performance of Tesla’s driverless Robotaxis in Austin.

Parking performance impressed, with most spots nailed perfectly, including tight, sharp turns, in single attempts without shaky steering. One minor offset happened only due to another vehicle that was parked over the line, which FSD accommodated by a few extra inches. In rain that typically erases road markings, FSD visualized lanes and turn lines better than humans, positioning itself flawlessly when entering new streets as well.

“Took it up a dark, wet, and twisty canyon road up and down the hill tonight and it went very well as to be expected. Stayed centered in the lane, kept speed well and gives a confidence inspiring steering feel where it handles these curvy roads better than the majority of human drivers,” the Tesla owner wrote in a post on X.

Tesla’s FSD v14.2.2 update

Just a day before FSD v14.2.2.1’s release, Tesla rolled out FSD v14.2.2, which was focused on smoother real-world performance, better obstacle awareness, and precise end-of-trip routing. According to the update’s release notes, FSD v14.2.2 upgrades the vision encoder neural network with higher resolution features, enhancing detection of emergency vehicles, road obstacles, and human gestures.
