NASA says SpaceX's Crew Dragon abort test is go for launch on doomed Falcon 9 rocket
NASA has formally given SpaceX permission for Crew Dragon’s second launch – a crucial test flight that should be the last before SpaceX launches NASA astronauts to the International Space Station (ISS) for the first time ever.
Known as its In-Flight Abort (IFA) test, Crew Dragon will attempt to escape a Falcon 9 rocket while airborne, a feat that CEO Elon Musk says will almost certainly destroy the rocket in the process. Technically speaking, NASA and SpaceX completed what is known as a Launch Readiness Review (LRR) sometime on Thursday, allowing SpaceX to proceed with launch preparations. By all accounts, Crew Dragon’s IFA test will likely be one of the most spectacular SpaceX launches ever, given that it is all but guaranteed to result in the intentional in-flight failure of a massive Falcon 9 rocket – “destroyed in Dragon fire” according to Musk.
Thanks to a much smoother launch flow compared to Crew Dragon’s Demo-1 orbital launch debut on Falcon 9, SpaceX’s newest Crew Dragon capsule is scheduled to lift off from Kennedy Space Center Launch Complex 39A (KSC LC-39A) as early as 8 am EST (13:00 UTC), Saturday, January 18th. The In-Flight Abort test will likely be one of Crew Dragon’s most challenging hurdles yet but success would be a major boon for the spacecraft’s demonstrated safety. While both Boeing and SpaceX will ultimately ferry NASA astronauts to and from the ISS, only SpaceX chose to prove Crew Dragon’s in-flight abort capabilities in the real world.
Effectively condemned to destruction to support a greater cause after a productive life, Falcon 9 Block 5 booster B1046 rolled out to Pad 39A – Crew Dragon mounted atop it – on January 16th after successfully performing its last routine static fire on the 11th. As previously discussed on Teslarati, B1046 is the first Falcon 9 Block 5 booster completed by SpaceX and is thus also the oldest flightworthy rocket in the company’s substantial fleet.
“After becoming the first SpaceX booster to launch three times in December 2018, B1046 spent several months at SpaceX’s Hawthorne, CA factory undergoing inspections and refurbishment. At some point, SpaceX assigned the thrice-flown booster to support Crew Dragon’s In-Flight Abort (IFA) test – effectively a death sentence – and shipped the booster to Florida, where it publicly appeared for the first time in months on October 3rd, 2019. Given that four more Falcon 9 boosters have now successfully performed three (or even four) orbital-class launches each, B1046’s now-imminent demise is certainly disappointing but remains extremely pragmatic.”

As such, there is arguably no better booster for SpaceX to expend even if its loss is still less satisfying than a successful post-launch landing. In fact, aside from NASA’s prematurely-retired Space Shuttle, the entire history of orbital-class rocketry has effectively operated on the assumption that it’s both normal and necessary for rockets to be almost entirely expendable.
Only by sheer force of will has SpaceX turned that assumption on its head, making the act of expending Falcon 9 or Falcon Heavy boosters feel suddenly morose. Even then, the practice of propulsively landing orbital-class boosters is scarcely four years old, while reusing those boosters has been ongoing for less than three years. As such, B1046’s demise should be enjoyed for what it ultimately is: the spectacular retirement of a rocket that has already helped launch three separate payloads to orbit.
Perhaps even more importantly, B1046’s sacrifice should – if things go as planned – also pave the way for Crew Dragon to launch its first NASA astronauts into orbit just a few months from now. For the test to be successful, however, Crew Dragon will have to perform an extremely precise string of maneuvers – the failure of any one of which could potentially lead to the spacecraft’s destruction.
“Traveling as fast as Mach 2.5 (860 m/s) at an altitude of 28 kilometers (17 mi), Crew Dragon will ignite its abort thrusters and attempt to escape, the very act of which will likely hammer the spacecraft’s windward surfaces with an extra dozen or so metric tons (~25,000 lb) of aerodynamic pressure. Crew Dragon C205 could thus find itself traveling almost Mach 3 (more than a kilometer per second) moments after separating from Falcon 9, eventually reaching an apogee of almost 75 km (45 mi), after which it will reenter the bulk of Earth’s atmosphere and have to deploy an array of parachutes to ensure a gentle Atlantic Ocean splashdown.”

Unfortunately, Crew Dragon escaping a supersonic Falcon 9 also means that that same Falcon 9 – basically a thin, flexible tube designed to be as light as possible – will meet a supersonic blast of air the moment Dragon’s SuperDraco abort thrusters ignite. A bit like if a hurricane on all kinds of meteorological steroids just sort of punched a soda can for fun, that airstream will almost certainly obliterate Falcon 9’s sacrificial upper stage into a sort of aluminum snow, quickly revealing – and likely then destroying – B1046’s carbon fiber interstage.
The rest of the thrice-flown Falcon 9 booster is also liable to break up after that supersonic punch. In fact, SpaceX engineers are so confident in B1046’s imminent demise that the booster will have neither landing legs or grid fins come launch. In a best-case scenario, if, against all odds, B1046 survives Dragon’s escape, the intact booster will subsequently impact the Atlantic Ocean at terminal velocity and become a nice, artificial reef off the coast of Florida. Stay tuned for updates from Teslarati and photographers Jamie Groh and Richard Angle as Falcon 9 B1046’s demise inches ever closer.

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.
