SpaceX’s first ever Block 5 booster gives one last hurrah, in photos
After helping SpaceX enter a new era of routine rocket reusability, the very first Falcon 9 Block 5 booster is officially nothing more than bits, pieces, and a few artificial reefs at the bottom of the Atlantic Ocean — intentionally destroyed to give SpaceX the confidence it needs to soon launch astronauts.
Captured on camera by Teslarati photographer Richard Angle, the upgraded Falcon 9 booster was able to give one last spectacular hurrah prior to its even more spectacular demise, returning fire to Kennedy Space Center (KSC) Launch Complex 39A for the first time in more than half a year. Lacking landing legs and grid fins, visible instead as comically stark outlines on the booster’s sooty exterior, Falcon 9 B1046 lifted off for the fourth and final time on January 19th, 2020.
In doing so, B1046 became the third orbital-class booster ever to fly launch four separate missions — a more than fitting end to the first in a line of upgraded Falcon 9 rockets that have brought with them major improvements in reusability and reliability. Nevertheless, a little over 90 seconds after lifting off for the fourth time, Falcon 9 B1046 – left behind after Crew Dragon successfully escaped the (simulated) failing rocket – yielded under intense off-nominal stresses, rupturing the booster’s propellant tanks and creating a vast fireball at least 300 meters (1000+ ft) in diameter.
Powered by nine Merlin 1D engines and capable of producing up to 7600 kN (1.7 million lbf) of thrust, Falcon 9 B1046 was extensively tested at SpaceX’s McGregor, Texas development facilities over a period of two or so months – unusually lengthy. The extra time was used to make sure that the first completed Block 5 booster – representing an almost clean-slate upgrade of the Falcon rocket family – was agreeing with SpaceX’s engineering models and expectations at all points.
The company likely spent several weeks or more performing numerous wet dress rehearsals (WDRs) — filling Falcon 9 B1046’s propellant tanks with liquid oxygen, refined kerosene (RP-1), helium, and nitrogen and verifying that the rocket was structurally sound and functioning smoothly. Once complete, SpaceX moved onto static fire testing, igniting the booster’s M1D engines for increasing periods of time. Finally, the company wrapped up the rocket and shipped it by road from Texas to Florida.
Shortly thereafter, the rocket was quickly prepared for flight and became the first Falcon 9 Block 5 booster to successfully launch and land in May 2018. Over the course of 2018, SpaceX debuted another five Block 5 boosters, while Falcon 9 B1046 became the first Block 5 booster to launch both twice and three times in August and December.
Finally, on January 19th, 2020, Falcon 9 B1046 lifted off for the fourth and last time, becoming the third SpaceX booster to do so in barely two months. Fittingly, B1046’s last launch occurred at Pad 39A, the same launch site it lifted off from for the first time back in May 2018. Carrying an expendable upper stage, Dragon trunk, and Crew Dragon capsule C205, B1046 could not have experienced a more perfect 90 or so seconds of uninterrupted flight. Interrupted, however, it would shortly thereafter become.
Around 85 seconds after liftoff, Falcon 9 B1046 shut off its Merlin 1D engines at the same time as Crew Dragon C205 ignited eight SuperDraco engines, briskly carrying the spacecraft several thousand feet away in just a handful of seconds. Now fully uncontrolled and rudely interrupted to a supersonic wall of air, B1046 found itself bent and contorted in ways – and under loads – it simply was not designed to survive. Seconds later, the booster’s pressurized propellant tanks were breached, releasing a rapidly dispersing cloud of fuel and oxidizer that almost instantly ignited, creating a fireball the size of several city blocks.
All things considered, not a bad way to go for a well-worn rocket.

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.

Tesla AI team burns the Christmas midnight oil by releasing FSD v14.2.2.1
The update was released just a day after FSD v14.2.2 started rolling out to customers.
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.
New Arrival Options also allowed users to select preferred drop-off styles, such as Parking Lot, Street, Driveway, Parking Garage, or Curbside, with the navigation pin automatically adjusting to the ideal spot. Other refinements include pulling over for emergency vehicles, real-time vision-based detours for blocked roads, improved gate and debris handling, and Speed Profiles for customized driving styles.
