SpaceX has accidentally dropped one of its newest Falcon 9 booster’s landing legs during a retraction attempt in Port Canaveral while crews worked to prepare the rocket for transport.

Falcon 9 booster B1060 safely arrived in Port Canaveral, Florida on July 4th after a flawless June 30th launch debut, delivering the US military’s GPS III SV03 navigation satellite to an accurate orbit and becoming the first SpaceX rocket to launch and land as part of an operational US military mission. The major landing milestone was supported by drone ship Just Read The Instructions (JRTI) as part of its second East Coast recovery mission ever after an ~8000 km (~5000 mi) journey from Los Angeles and months of slow and steady upgrades.

Thankfully, despite the mishap caught on camera by diligent, unofficial observers, things appeared to work out just fine for booster B1060 as crews threaded recovery operations between bouts of disruptive Florida weather.

Based on video of the accidental leg drop captured by US Launch Report on July 7th, the most obvious conclusion is that operators either failed to release tension on a winch line or some kind of hardware/software/sensor failure unintentionally over-stressed the line. Regardless, around the same time as Falcon 9 or its ground operators were likely commanding the landing leg latch closed, one or both of the lines attached to the top of the retracting leg snapped, causing it to very quickly redeploy as gravity pulled it back to earth.

Almost certainly by design, nobody was underneath the ~1000 kg (~2200 lb) landing leg during retraction, and a small stand used to prop up the leg for winch line installation seems to have been moved out of the line of fire as part of the process. As a result, when the leg was accidentally released, it simply fell onto drone ship JRTI’s flat, steel deck under its own weight. Most importantly, nobody was (visibly) injured or at risk of injury

The landing leg’s impact and aftershock looks undeniably harsh in the footage but the reality is that SpaceX has already performed almost identical tests (albeit intentionally) on recovered boosters while leg retraction was still in development. Captured in the video above, B1049’s September 2018 leg retraction and deployment test appeared to be marginally gentler than B1060’s accidental leg smack, and B1049 went on to complete four more orbital-class launches without issue. That still ignores the fact that Falcon 9’s landing legs are designed to withstand extremely rough landings of entire ~30 metric ton boosters traveling up to several meters per second (~5 mph) – vastly more force than a single landing leg can exert on itself with gravity as the only input.

Confirming those suspicions, SpaceX ultimately got back on the saddle after a few slight weather delays and successfully retracted all four of B1060’s landing legs without issue. The once-flown rocket was quickly broken over (referring to the process of lowering it horizontally) and installed on a custom transporter, which will soon move it from Port Canaveral to a nearby SpaceX hangar (likely Pad 39A’s) to prepare for its next launch.

Tesla supplier Samsung preps for AI5 production with latest move

Tesla supplier Samsung is preparing to manufacture the AI5 chip, which will launch the company’s self-driving efforts even further, with its latest move.

According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team, which will help resolve complex foundry challenges, stabilize production and yields, and ensure manufacturing goes smoothly for the new project.

The hiring push signals that Tesla’s AI5 project is moving forward quickly at Samsung, which was one of two suppliers to win a contract order from the world’s leading EV maker.

TSMC is the other. TSMC is using its 3nm process, reportedly, while Samsung will do a 2nm as a litmus test for the process.

The different versions are due to the fact that “they translate designs to physical form differently,” CEO Elon Musk said recently. The goal is for the two to operate identically, obviously, which is a challenge.

Some might remember Apple’s A9 “Chipgate” saga, which found that the chips differed in performance because of different manufacturers.

The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, but it will also contribute to the Optimus program and other AI-driven features in both vehicles and other projects. Currently, Tesla utilizes AI4, formerly known as HW4 or Hardware 4, in its vehicles.

Tesla teases new AI5 chip that will revolutionize self-driving

AI5 is specialized for use by Tesla as it will work in conjunction with the company’s Neural Networks, focusing on real-time inference to make safe and logical decisions during operation.

Musk said it was an “amazing design” and an “immense jump” from Tesla’s current AI4 chip. It will be roughly 40 times faster, and have 8 times the raw compute, with 9 times the memory capacity. It is also expected to be three times as efficient per watt as AI4.

AI5 will make its way into “maybe a small number of units” next year, Musk confirmed. However, it will not make its way to high-volume production until 2027. AI5 is not the last step, either, as Musk has already confirmed AI6 would likely enter production in mid-2028.

Tesla discloses interesting collaboration partner for Supercharging

This BOXABL collaboration would be a great way to add a rest stop to a rural Supercharging location, and could lead to more of these chargers across the U.S.

Tesla disclosed an interesting collaboration partner in an SEC filing, which looks like an indication of a potential project at Supercharger sites.

Tesla said on Tuesday in the filing that it was entering an agreement with BOXABL to design and build a Micromenity structure. Simply put, this is a modular building, usually a few hundred square feet in size, and it has been seen at Superchargers in Europe.

In Magnant, France, Tesla opened a small building at a Supercharger that is available to all EV owners. There are snacks and drinks inside, including ice cream, coffee, a gaming console, and restrooms. It gives people an opportunity to get up and out of their cars while charging.

This building was not built by BOXABL, but instead by bk World Lounges. It is likely the final Supercharging stop before people get to Paris, as it is located 250 kilometers, or 155 miles, from the City of Light.

Magnant has 56 stalls, so it is a large Supercharging stop compared to most. The building could be a sign of things to come, especially as Tesla has opened up larger Supercharger stations along major roadways.

It is for just a single building, as the Scope of Work within the filing states “a comprehensive package for one Micromenity building.”

Superchargers are commonly located at gas stations, shopping centers, and other major points of interest. However, there are some stops that are isolated from retail or entertainment.

This BOXABL collaboration would be a great way to add a rest stop to a rural Supercharging location, and could lead to more of these chargers across the U.S.

Tesla has done a lot of really great things for Supercharging this year.

Along with widespread expansion, the company launched the “Charging Passport” this week, opened the largest Supercharger in the world in Lost Hills, California, with 168 chargers, opened the Tesla Diner, a drive-in movie restaurant in Los Angeles, and initiated access to the infrastructure to even more automakers.

Tesla CEO Elon Musk confirms Robotaxi safety monitor removal in Austin: here’s when

Musk has made the claim about removing Safety Monitors from Tesla Robotaxi vehicles in Austin three times this year, once in September, once in October, and once in November.

Tesla CEO Elon Musk confirmed on Tuesday at the xAI Hackathon that the company would be removing Safety Monitors from Robotaxis in Austin in just three weeks.

This would meet Musk’s timeline from earlier this year, as he has said on several occasions that Tesla Robotaxis would have no supervision in Austin by the end of 2025.

On Tuesday, Musk said:

“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.”

Musk has made the claim about removing Safety Monitors from Tesla Robotaxi vehicles in Austin three times this year, once in September, once in October, and once in November.

In September, he said:

“Should be no safety driver by end of year.”

On the Q3 Earnings Call in October, he said:

“We are expecting ot have no safety drivers in at least large parts of Austin by the end of this year.”

Finally, in November, he reiterated the timeline in a public statement at the Shareholder Meeting:

“I expect Robotaxis to operate without safety drivers in large parts of Austin this year.”

Currently, Tesla uses Safety Monitors in Austin in the passenger’s seat on local roads. They will sit in the driver’s seat for highway routes. In the Bay Area ride-hailing operation, there is always a Safety Monitor in the driver’s seat.

Three weeks would deliver on the end-of-year promise, cutting it close, beating it by just two days. However, it would be a tremendous leap forward in the Robotaxi program, and would shut the mouths of many skeptics who state the current iteration is no different than having an Uber.

Tesla has also expanded its Robotaxi fleet this year, but the company has not given exact figures. Once it expands its fleet, even more progress will be made in Tesla’s self-driving efforts.
