After knocking out some figurative cobwebs, SpaceX has test-fired a Falcon Heavy rocket for the first time since June 2019.

Shortly before the static fire, NASASpaceflight’s Thomas Burghardt reported that Falcon Heavy’s first launch in 40 months – a mission for the US Space Force known as USSF-44 – had slipped from October 28th and October 31st to no earlier than (NET) 9:40 am EDT (13:40 UTC), Tuesday, November 1st. USSF-44 will be Falcon Heavy’s fourth launch since February 2018.

During its 10-second October 27th static fire, Falcon Heavy – the most capable rocket currently operational – appeared to ignite all 27 of its first stage’s Merlin 1D engines, likely producing up to 2350 tons (5.18 million lbf) of thrust. Only three liquid-powered rockets (N1, Saturn V, & Energia) and one rocket augmented by solid rocket boosters (the Space Shuttle) have produced more thrust at sea level, and the most recently active of those four vehicles (NASA’s Space Shuttle) was permanently retired in 2011.

NASA’s Space Launch System (SLS) rocket will retake the crown when it (hopefully) debuts later this year, but Falcon Heavy will remain the most powerful commercially-available rocket until SpaceX’s own Starship debuts. After Starship debuts later this year or early next, Falcon Heavy will continue on as the second most powerful commercial rocket for the indefinite future.

After more than three years of downtime, SpaceX unsurprisingly appeared to run into minor issues while preparing Falcon Heavy for a full wet dress rehearsal and static fire. SpaceX rolled the rocket – sans payload fairing – out to the launch pad late on October 25th, at which point the launch target had already slipped to October 31st. Falcon Heavy then sat horizontally for about 30 hours before SpaceX raised it vertical and fully attached the rocket and transporter/erector to the pad’s ground systems.

Another 12 hours of work later, SpaceX was ready to begin static fire test operations, and Falcon Heavy fired up at 8 pm EDT on October 27th, 50 hours after it rolled out. During Falcon 9’s most recent satellite launch out of Pad 39A, the rocket lifted off about 30 hours after rollout. While preparing for Falcon Heavy Block 5’s first launch (Flight 2 overall) in April 2019, the rocket went vertical 12 hours after rollout – 18 hours faster than Flight 4. Ahead of Flight 3 in June 2019, Falcon Heavy completed a static fire test 25 hours after rolling out – 25 hours faster than Flight 4.

Before it can launch, Falcon Heavy will have to return to LC-39A’s hangar to have its fairing (containing two classified USSF-44 satellites) installed and then return to the pad, repeating the rollout process. Falcon Heavy Flight 3 holds the record (5d 4h) for the shortest gap between a static fire and launch. Falcon Heavy’s updated launch target is 4 days and 14 hours after its static fire, meaning that SpaceX will have to break that record to launch USSF-44 as planned.

Update: The USSF-44 payload fairing – satellites safely encapsulated inside it – headed to Pad 39A less than four hours after Falcon Heavy Flight 4’s static fire.

Regardless, with a successful static fire under its belt, Falcon Heavy’s fourth launch is now all but guaranteed to occur within the next 5-10 days. The rocket’s fifth launch – carrying ViaSat’s first ViaSat-3 communications satellite – could follow as early as December 2022, and another four Falcon Heavy launches are currently scheduled between January and August 2023.

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.”

The executives’ unoccupied tests hint at the rapid progress of Tesla’s unsupervised Robotaxi efforts.

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.

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.
