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.

Cheaper launches as a result of reusable rockets may not necessarily increase demand for satellite launches.

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.

Tesla Cybercab includes this small but significant feature

The Cybercab is Tesla’s big plan to introduce fully autonomous ride-sharing in a seamless fashion. In fact, the Full Self-Driving suite was geared toward alleviating the need to manually drive vehicles.

Tesla Cybercab manufacturing is strikingly close, as the company is still aiming for an April start date. But small and significant features are still being identified for the first time as production units appear all over the country for testing and for regulatory events, like one yesterday in Washington, D.C.

The Cybercab is Tesla’s big plan to introduce fully autonomous ride-sharing in a seamless fashion. In fact, the Full Self-Driving suite was geared toward alleviating the need to manually drive vehicles.

This was for everyone, including the disabled, who are widely reliant on ride-sharing platforms, family members, and medical shuttles for transportation of any kind. Cybercab aims to change that, and Tesla evidently put a focus on those riders while developing the vehicle, evident in a small but significant feature revealed during its appearance in the Nation’s Capital.

Tesla has implemented Braille within the Cybercab to make it easier for blind passengers to utilize the vehicle. On both the ‘Stop/Hazard Lights’ button and the Door Releases, Tesla has placed Braille so that blind passengers can navigate their way through the vehicle:

This is a great addition to the Cybercab, especially as Full Self-Driving has been partially pointed at as a solution for those with disabilities that would keep them from driving themselves from place to place.

It truly is a great addition and just another way that Tesla is showing they are making this massive product inclusive for everyone out there, including those who have not been able to drive due to not having vision.

The Cybercab is set to enter mass production sometime in April, and it will be responsible for launching Tesla’s massive plans for an autonomous ride-sharing program.

Tesla and xAI team up on massive new project

It is the latest move by a Musk company to automate, streamline, and reduce the manual, monotonous, and tedious work currently performed by humans through AI and robotics development. Digital Optimus will be capable of processing and actioning the past five seconds of a real-time computer screen video and keyboard and mouse actions.

Elon Musk teased a massive new project, to be developed jointly by Tesla and xAI, called “Digital Optimus” or “Macrohard,” the first development under Tesla’s investment agreement with xAI.

Musk announced on X that Digital Optimus will “be capable of emulating the function of entire companies.”

It is the latest move by a Musk company to automate, streamline, and reduce the manual, monotonous, and tedious work currently performed by humans through AI and robotics development. Digital Optimus will be capable of processing and actioning the past five seconds of a real-time computer screen video and keyboard and mouse actions.

Essentially, it will be an AI version of a desk worker in many capacities, including accounting, HR tasks, and others.

Musk said:

“Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of real-time computer screen video and keyboard/mouse actions. Grok is like a much more advanced and sophisticated version of turn-by-turn navigation software. You can think of it as Digital Optimus AI being System 1 (instinctive part of the mind) and Grok being System 2. (thinking part of the mind).”

Its key applications would be used for enterprise automation, simulating entire companies, high-volume repetitive tasks, and potentially, future hybrid use with the Optimus robot, which would handle physical tasks, while Digital Optimus would handle the clerical work.

Tesla announces massive investment into xAI

The creation of a digital AI suite like Digital Optimus would help companies save time and money, as well as become more efficient in their operations through massive scalability. However, there will undoubtedly be concerns from people who are skeptical of a fully-integrated AI workhorse like this one.

From an energy consumption perspective and just a general concern for the human workforce, these types of AI projects are polarizing in nature.

However, Digital Optimus would be a great digital counterpart to Tesla’s physical Optimus robot, as it would be a hyper-efficient addition to any company that is looking for more production for less cost.

Musk maintains that there is no other company on Earth that will be able to do this.

Tesla China sold 58,599 vehicles wholesale in February, reflecting strong year-over-year growth. The figure includes both domestic deliveries in China and vehicles exported to international markets.

The update was shared by Tesla observers on social media platform X, citing monthly China Passenger Car Association (CPCA) data.

Tesla’s February wholesale result represents a 91% increase year over year, compared with 30,688 vehicles in February 2025. Month over month, the result was down 15.2% from January, when Tesla China recorded 69,129 wholesale units.

The February total reflects combined sales of the Model 3 and Model Y produced at Gigafactory Shanghai. The facility produces the two vehicles for both domestic sales and exports.

Gigafactory Shanghai continues to serve as Tesla’s primary vehicle export hub, supplying vehicles to markets across Asia and Europe. Data compiled by Tesla watchers shows that 18,485 vehicles were sold domestically in China in January 2026, while exports accounted for 50,644 units during the same period.

Tesla has also been extending financing programs in China as it pushes to strengthen domestic demand. The company recently extended its seven-year ultra-low-interest and five-year interest-free financing programs through March 31, marking the second extension of the promotion this year.

The financing initiative was first introduced on January 6 as a strategy aimed at offsetting higher ownership costs ahead of China’s planned 5% NEV purchase tax in 2026. The promotion was originally scheduled to expire at the end of January before being extended to February and then again through the end of the first quarter.

Tesla’s efforts come amid growing competition in China’s EV market. According to data compiled by CNEV Post, Tesla’s 2025 retail sales in China reached 625,698 vehicles, representing a 4.78% year-over-year decline. Part of that decline was linked to the Model Y changeover to its updated variant in early 2025, which temporarily reduced deliveries during the transition period.
