SpaceX’s next Falcon Heavy launch – set to be the rocket’s fourth overall – has slipped several months into 2021 according to the vice commander of the US Air Force Space and Missile Systems Center (USAF SMC).

Known as AFSPC-44 (now USSF-44), the nature of Falcon Heavy’s next payload remains a mystery. Headed to geostationary orbit, the satellite will likely be involved in military satellite communications, possibly including espionage (also known as signals intelligence or SIGINT). Technically, the USSF-44 mission includes two separate satellites and at least two additional rideshare payloads and will weigh roughly 3.7 metric tons (~8200 lb) at launch.

When the contract was announced, Falcon Heavy was expected to launch USSF-44 no earlier than (NET) Q4 2020. By April 2020, that target was closer to late November or December. Now, four months after that report, Brigadier General Jason Cothern says that SpaceX’s next Falcon Heavy launch is scheduled NET February 28th, 2021.

The delay doesn’t come as much of a surprise. Based on public observation of SpaceX’s Falcon booster production and testing, requiring thousands of miles of extremely conspicuous highway transport, it was already clear that the mission was unlikely to launch this year. Of the six first stages spotted in transport over the last nine months, all were clearly Falcon 9 boosters and lacked any of the telltale parts that distinguish Falcon Heavy side and center boosters.

The most recent ‘core spottings’ – a new Falcon 9 booster headed West after acceptance testing and another preparing for acceptance testing in Texas late last month – all but confirmed that USSF-44 was significantly delayed. Since mid-2019, SpaceX has intentionally slowed down Falcon booster production to focus on the higher-volume production of expendable hardware (fairings and second stages). While the company could technically complete boosters every two weeks if its feet were put to the coals and has generally averaged 10 per year, that figure has dropped closer to 6-8 boosters per year over the last ~18 months.

Coupled with a report that all three of the USSF-44 Falcon Heavy rocket’s boosters would be brand new, the lack of sightings in the wild implied that has yet to ship even one of those complex rockets to McGregor, Texas for acceptance testing. Based on preparations for Falcon Heavy’s April 2019 Block 5 launch debut, the process of testing three new Falcon boosters singlehandedly takes at least three months. Additionally, all three of the Arabsat 6A mission’s new Falcon Heavy boosters arrived in Florida a full two months before launch.

In other words, given that a brand new Falcon 9 booster rolled out of SpaceX’s Hawthorne, CA factory on August 24th and that said factory isn’t really set up for concurrent booster completion, it would take unprecedented feats of manufacturing and testing for Falcon Heavy Flight 4 to be ready to launch less than four months from now (around the turn of the New Year).

In fact, even under the assumption that the next three boosters on SpaceX’s factory assembly line are all for Falcon Heavy Flight 4, the new February 2021 launch date is going to be a tight deadline. There is no evidence that SpaceX production delays are to blame for the USSF-44 launch delay and the coronavirus-related disruption of satellite production is equally – if not more – likely. Either way, SpaceX’s fourth Falcon Heavy launch will have to wait a few extra months. Barring a surprise mission over the next six months, Falcon Heavy Flight 4 will also be SpaceX’s first operational launch directly to geostationary orbit (GEO).

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.
