Some 12 hours after Falcon Heavy successfully completed what Elon Musk described as the SpaceX’s “most difficult launch ever”, the CEO took to Twitter to offer some insight into the mission’s only sad note – an unsuccessful center core recovery attempt.

The second Falcon Heavy Block 5 center core built by SpaceX, B1057 suffered an untimely demise shortly after its first (and last) launch, failing to successfully land aboard drone ship Of Course I Still Love You (OCISLY). Although an undeniable disappointment, the overall STP-2 mission was a spectacular success and will without a doubt serve SpaceX well as the company eyes its first certified Falcon Heavy launches for the US military. New center cores can and will be produced and there should be no doubt that SpaceX will eventually perfect center core recovery (or transcend the need entirely with Starship).

As noted by both CEO Elon Musk and several SpaceX engineers-turned-webcast-hosts, aside from the fact that the overall mission was by far the company’s most challenging yet, center core B1057’s recovery was also expected to be the most challenging booster landing ever. The booster’s landing target was drone ship OCISLY, stationed a record-smashing 1240 km (770 mi) off the coast of Florida – almost 30% further than any previous recovery attempt.

Sadly, SpaceX either chose not to broadcast the center core’s onboard camera during reentry or the booster could not maintain a downlink connection during the ordeal. However, based on basic info that was included in the webcast, B1057 completed its boost burn and separated from the upper stage and Space Test Program-2 (STP-2) payload some 3 minutes and 40 seconds after lifting off from Pad 39A. At MECO (main-engine cutoff), the building-sized booster was traveling a blistering 3.1 km/s (Mach 9) at an altitude of more than 120 km (75 mi).

Running on slim propellant margins, the booster coasted through vacuum almost the entire way to drone ship OCISLY. Around 9 minutes after launch, B1057 began its entry burn, likely igniting three Merlin 1D engines to effectively cushion it against the worst of atmospheric reentry heating. Unintuitively, much of the actual benefit of that burn derives from that cushioning effect, while the burn only slows the booster down by a few hundred meters per second (mph).

Effectively falling in near-vacuum conditions, pulled by gravity, B1057 could easily have been traveling 3.5-4 km/s (Mach 10-12) by the time Earth’s atmosphere began to slow it down. Described by Musk himself, back-of-the-envelope analysis of available telemetry apparently indicated that that spectacularly fast and hot reentry either burned through B1057’s heavy titanium heat shield or broke through the smaller heat shield surrounding its M1D engine bells.

In short, the brutal heating and buffeting of hypersonic atmospheric reentry damaged the rocket’s central M1D engine, necessary for an accurately controlled drone ship landing. Incredibly, B1057 actually appeared to make it almost all the way to a successful recovery, veering off course just a few hundred meters above OCISLY. Musk also noted that this may have actually been an instance of the rocket’s autonomous guidance computer intentionally abort a landing attempt to protect the drone ship. It’s possible that the reentry didn’t fully destroy components, but rather damaged them to the point that they failed only after a sustained landing burn.

Regardless, the end result is unambiguous. Falcon Heavy center core B1057 did its job perfectly, supporting the STP-2 launch, boosting the upper stage and payload almost half the way to orbit, and eventually sacrificing itself to avoid potentially damaging OCISLY. SpaceX’s next Falcon Heavy launch is currently scheduled to launch the very large AFSPC-52 military satellite no earlier than September 2020, a full 15 months away. The company should have no trouble manufacturing multiple new center cores between now and then.

Tesla begins production of new Model Y trim at Giga Berlin

Tesla announced on Monday that its Model Y Standard configuration was officially being built at Giga Berlin, less than one month after the company officially announced the configuration early last month.

Tesla has begun production of the new Model Y trim at Gigafactory Berlin, the company’s production plant in Germany.

Tesla announced on Monday that its Model Y Standard configuration was officially being built at Giga Berlin, less than one month after the company officially announced the configuration early last month.

On October 7, Tesla announced the launch of the Model 3 and Model Y Standard trim levels, its answer to the call for affordable EVs within its lineup and its response to the loss of the $7,500 electric vehicle tax credit.

On October 3, Tesla started production of the vehicles in Germany:

The Standard iteration of the Model Y is void of many of the more premium features that are available in the Rear-Wheel-Drive, All-Wheel-Drive, and Performance trims of the vehicle are equipped with.

A few of the features of the Model Y Standard are:

  • Single Motor configuration
  • No rear touchscreen
  • Textile seats with vegan leather, instead of all vegan leather
  • 320-mile range
  • No glass roof

The launch of the Model Y Standard was truly a move to help Tesla get vehicles into the sub-$40,000 price point, and although many consumers were hoping to see the company get closer to $30,000 with these cars, this is a great starting point.

Deliveries in the United States have already started, and it seems it will be a vehicle that will do one of two things: either push some consumers to finally make the jump to Tesla, or it will give car buyers another reason to buy the Premium trims, as they may feel the lack of features is not a good enough deal.

This is something we saw with the Cybertruck’s Rear-Wheel-Drive configuration, which launched last year and ended up being more of the latter option listed above.

The Tesla Model Y Standard is actually a great deal in Europe

It was only a $10,000 discount from the All-Wheel-Drive Cybertruck, but it also did not have adaptive air suspension, premium interiors, or the powered tonneau cover, which many people felt was too much of a sacrifice.

The Rear-Wheel-Drive Cybertruck was discontinued only a few months later.

It does not seem as if this is the case with the Model Y Standard, which already seems to be an attractive option to some buyers.

Tesla has officially begun the wide rollout of Full Self-Driving (Supervised) v14 to the Cybertruck about a month after the company started rolling it out to other vehicles in the fleet.

On Monday, Tesla officially started rolling out v14.1.5 to Cybertruck owners, the first FSD v14 rollout for owners of the all-electric pickup.

Owners have been anxiously waiting for Tesla to begin the wide release of v14 to Cybertruck, as the company said it would refine the suite for the vehicle.

Tesla has finally started rolling out to many owners, who are reporting that their Cybertrucks are downloading Software Update 2025.38.8.5, which contains FSD v14.1.5:

Tesla has to be more cautious with rolling out FSD on the Cybertruck than on other vehicles for a few reasons. Initially, the Cybertruck utilizes an all-wheel steering system that turns differently than the S3XY lineup. This creates a challenge for the Tesla AI team as they have to cater to this specific maneuvering change.

Additionally, the Cybertruck is much larger, and the exterior cameras responsible for seeing the vehicle’s surroundings are placed differently than those of the other vehicles.

This requires additional calibration to ensure safety.

The full release notes for Full Self-Driving v14.1.5 are as follows:

  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, in a Parking Garage, or at the Curbside.
  • Added handling to pull over or yield for emergency vehicles (e.g. police cars, fire trucks, ambulances).
  • Added navigation and routing into the vision-based neural network for real-time handling of blocked roads and detours.
  • Added additional Speed Profile to further customize driving style preference.
  • Improved handling for static and dynamic gates.
  • Improved offsetting for road debris (e.g. tires, tree branches, boxes).
  • Improve handling of several scenarios including: unprotected turns, lane changes, vehicle cut-ins, and school buses.
  • Improved FSD’s ability to manage system faults and recover smoothly from degraded operation for enhanced reliability.
  • Added alerting for residue build-up on interior windshield that may impact front camera visibility. If affected, visit Service for cleaning!

Elon Musk shuts down Tesla ‘AMG’ division speculation: ‘Focus is autonomy’

“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”

Tesla CEO Elon Musk was asked by Joe Rogan late last week whether the company would ever consider establishing an “AMG division” like Mercedes-Benz has established for powerful, race-inspired vehicles.

However, Musk turned down any talk of that, highlighting that the company is laser-focused on autonomous vehicles, seemingly hinting that any distraction from autonomy would be a detriment to the future.

Rogan drives a Tesla Model S himself, but it is not your run-of-the-mill all-electric sedan. Already outfitted with the Plaid powertrain that Tesla developed, Rogan took his vehicle to Unplugged Performance for a true performance outfitting.

The vehicle is completely overhauled with performance parts and seats. Known as the Model S-APEX, Rogan took delivery of it from Unplugged in January.

Rogan asked Musk on Friday during his most recent appearance on the Joe Rogan Experience podcast whether Tesla would ever establish an “AMG division” that would focus on catering Teslas to performance-based standards.

Musk said:

“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”

Tesla fans have said for years that the company should consider acquiring Unplugged Performance and its Upfit Tesla division, which recently outfitted the Las Vegas Metropolitan Police Department’s fleet of Cybertruck cruisers.

However, it seems Tesla will keep things separate. Musk is primarily focused on autonomy, which will drive the technology forward and drive shareholder growth. Something like an outfitter for performance would be a cool thing for the owners who have the interest and the money.

It’s not a tremendous revenue driver or anything that would contribute to the financial state of the company. Mercedes-Benz, for example, is more accessible for consumers as it sold over 140,000 units from its AMG brand in 2024.

It helps with driving revenue higher by as much as 15 percent compared to similar models that are not AMGs. However, would Tesla see this much of a benefit? Likely not, because the Performance trim already caters to many owners.
