SpaceX Falcon 9 booster sails into port after historic third launch and landing
Although a sister rocket did not fare nearly as well during a separate landing attempt 48 hours later, SpaceX Falcon 9 Block 5 booster B1046 nailed its third successful launch and landing on December 3rd and arrived in Port of Los Angeles a bit less than 48 hours later.
Greeting the rocket after its milestone third reuse was a rare Los Angeles rainstorm, lending a lovely reflective sheen to all uncovered surfaces as low clouds and an obscured sun bathed everything in a stark and uniform off-white light.
That’s one scorched booster, still standing on JRTI at the moment, in the rain. B1046.3 arrived back at port earlier this morning after launching and landing for the 3rd time during the SSO-A mission. What. A. Sight. #spacex pic.twitter.com/EhHY9HK9cD

It is difficult to conceive of a set of conditions that might serve to better emphasize the well-worn patina of soot and charring now fully covering the once-shiny white exterior of B1046’s fuel and oxidizer tanks, a sort of literal badge of honor for the three orbital-class launches the booster has now supported in the last six months. Functionally speaking, cleaning a Falcon 9 booster from top to bottom would be an unbelievably tedious, time-consuming, and largely pointless task, requiring careful spot-cleaning of something like 400 square meters (4300 square feet).

While SpaceX did repaint recovered Falcon 9 boosters a handful of times around the start of commercial reflights, it always served more of an aesthetic purpose over anything seriously utilitarian. Furthermore, aerospace-grade paint like that used by SpaceX is quite heavy potentially weighing several hundred kilograms per booster and requiring a week at minimum to fully apply a new coat. Some followers like to point out the lost benefits of Falcon 9’s reflective white paint, serving as a mild thermal insulator for Falcon 9’s tanks when filled with supercool propellant. While it certainly exists, the additional heating induced by soot coatings is completely negligible for Falcon 9, which is constantly topped off with chilled propellant prior to launch.
As such, sooty boosters will be around as long as the kerolox-power Falcon family remains in operation. Not too long from now, shiny new Falcon rockets will likely be as rare as the expendable rocket launches they partially represent – the launch vehicles of the future will be rugged workhorses more comparable to the 737s that fill the ranks of airliner fleets than to single-use works of art. Nevertheless, soot is by no means an innate feature of rockets, reusable or otherwise, instead deriving from Falcon 9’s pragmatic choice of kerosene as fuel – soot is simply an inevitable byproduct of kerosene combustion.

A long and sooty future
Whenever it begins flying, the sole byproducts of the combustion of BFR/Starlink/Super Heavy’s methane-oxygen (methalox) propellant are water vapor and carbon dioxide, although true methane supplies will inevitably have slight impurities and thus cause the negligible production of some less pleasant byproducts. Raptor, the methalox rocket engine that will power BFR, has been performing hot-fire tests for more than two years, and the sheer differences between the exhaust of Merlin and Raptor are a striking example of the different chemistries at work. As a result of much cleaner combustion, BFR may produce no soot byproducts whatsoever – enjoy it while it lasts!
In the meantime, Falcon 9 will continue to fly and refly for the foreseeable future. B1046’s third successful launch and recovery is a huge step in that direction and the very fact that the most noticeable difference is a new coating of soot at least partially hints at the efficacy of Block 5’s reusability-minded upgrades. Even when twice-flown Block 5 octaweb heat shields are glimpsed, it’s all but impossible to tell the difference between an unflown or twice-flown example, while the new jet-black thermal protection on Block 5 interstages and octawebs only exhibit subtle scarring after reentry heating.
It almost goes without saying that the real killer in multi-use aerospace products – fatigue – is rarely visible to the naked eye, so the external appearance of Falcon boosters is more of a swoon-worthy placebo than anything else. Still, Falcon 9 Block 5 continues to demonstrate that its external appearance is almost equally indicative of truly robust reusability engineering.

Tesla says it has launched ride-hailing Robotaxi teaser to employees only
Tesla is using Full Self-Driving (Supervised) to court employees around in two areas.

Tesla announced earlier today that it has already launched an abbreviated version of what will eventually be launched as its Robotaxi fleet in both Austin and the San Francisco Bay Area. It is available to employees, Tesla said.
The automaker did not specify exactly how long it has been operating the fleet, which uses the company’s Full Self-Driving (Supervised) suite, but it did indicate that it has completed over 1,500 trips, totaling 15,000 miles of driving.
FSD Supervised ride-hailing service is live for an early set of employees in Austin & San Francisco Bay Area.
We’ve completed over 1.5k trips & 15k miles of driving.
This service helps us develop & validate FSD networks, the mobile app, vehicle allocation, mission control &… pic.twitter.com/pYVfhi935W

As seen in the video shared by the company, there is a human driver still responsible for keeping tabs on the car and its movements. It is not the version that Tesla plans to eventually roll out in June, which would be completely unsupervised.
Tesla said that using this service has helped develop and validate Full Self-Driving networks. It will also be used to create a mobile app that will facilitate ride requests, vehicle allocation, mission control, and remote assistance operations.

The app appears to be somewhat similar to the images Tesla shared of a mock-up version of the platform last year.
Right around this time in 2024, Tesla shared images of what would be the ride-hailing app for the company, enabling passengers to request a ride from a driverless robotaxi:

We also know, according to Tesla App Updates on X, that Tesla will simply integrate this ride-hailing portion of the platform directly into the app the company already operates. There will be no dedicated app for requesting a ride:

The company said in 2024 when teasing the app:
“We have been investing in the hardware and software ecosystems necessary to achieve vehicle autonomy and a ride-hailing service. We believe a scalable and profitable autonomy business can be realized through a vision-only architecture with end-to-end neural networks, trained on billions of miles of real-world data.”
Tesla said it still remains on track to launch a pilot version of the Robotaxi program in Austin in June, something the company has reiterated several times since the start of the new year.

Tesla analyst sees brighter future after Elon Musk reduces DOGE work
Wedbush hikes TSLA’s price target after Musk says he’s cutting back on DOGE. Analyst Dan Ives calls it a “turning point” for Tesla’s story.

Wedbush Securities analyst Daniel Ives sees a brighter future for the automaker now that Elon Musk plans to reduce his time with the DOGE team. After the company’s latest earnings call, the long-time TSLA bull raised Tesla’s price target from $315 to $350 with a BUY rating.
“Last night was a pivotal conference call for Musk to turn the corner from this dark chapter as 1Q numbers [ending] a disaster quarter in which deliveries were very soft and Tesla missed the Street on basically every metric.
“More important than numbers, this was the time [Elon] Musk could pivot, speak to shareholders/employees, and take a turn away from the DOGE/Trump White House and recommit as CEO of Tesla…and he did it loudly and clearly in a conference call that we view as a turning point in the Tesla story,” Ives said after Tesla’s earnings call.
Before Tesla’s Q1 2025 earnings call, the Wedbush analyst said the company was at a crossroads. He listed six factors that might be affecting Tesla, which he believed the company should address. Number one on Ives’ list was Tesla’s ascension to a global political symbol associated with the Trump Administration and DOGE.
It must be noted that these are Ives’ opinions and do not apply to the entire public. Some groups separate Elon Musk and Tesla from President Trump and his administration.
During the recent TSLA earnings call, Elon Musk made the separation more apparent partly by announcing that he would significantly reduce his time with DOGE.
“And I think starting probably next month, May, my time allocation to Doge will drop significantly…But starting next month, I’ll be allocating far more of my time to Tesla and now that the major work of establishing the Department of Government Efficiency is done,” Musk said.
Musk also shared his stance on Trump’s auto tariffs, differentiating himself further from the U.S. President and the current administration.
“And I undoubtedly, I’m gonna get a lot of questions about tariffs. And I just wanna emphasize that the tariff decision is entirely up to the President of the United States. I will weigh in with my advice with the President, which he will listen to my advice. But then it’s up to him, of course, to make his decision.
“I’ve been on the record many times saying that I believe lower tariffs are generally a good idea for prosperity, but this decision is fundamentally up to the elected representative of the people being the President of the United States. So, you know, I’ll continue to advocate for lower tariffs rather than higher tariffs, but that’s all I can do,” Musk said.

Tesla units delivered in America have 100% ‘MADE IN THE USA’ battery packs

In its Q1 2025 Update letter, Tesla shared that all Model Y and Model 3 units delivered in America use 100% U.S.-built battery packs. The announcement reveals Tesla’s forward-thinking strategies and showcases how prepared it is to take on President Trump’s auto tariffs.
“Gigafactory Nevada achieved record battery pack production. Model 3 and Model Y deliveries in the U.S. are now made with 100% U.S.-built battery packs,” noted Tesla in its recent update letter.
During the TSLA Q1 2025 earnings call, Tesla’s Supply Chain Executive, Karn Budhiraj, noted that the company is regionalizing its batteries to mitigate supply chain risks.
“Building on our efforts to reduce supply risk, we have developed our 4680 supply to ensure each component is sourced from at least two countries of origin.” added Tesla in its letter.
Karn clarified that Tesla adopted its regionalization strategy before the pandemic and accelerated efforts after the pandemic. Tesla’s strategy to mitigate supply chain risks includes supply diversification, dual sourcing, vertical integration, advanced analytics, and local partnerships.
Elon Musk commented that Tesla might be the most vertically integrated car company since Henry Ford’s time. He pointed out that Tesla already has a lithium refinery in South Texas and a cathode refinery in Austin. He added that Tesla could have an anode refinery or figure out how to eliminate that part of the cell.
“That’s the dream, [for] lithium batteries to not have an anode. But either way, we better have the anode, the cathode, the lithium, and the electrolytes, and the separator to make a cell. But, there’s no other car company that is building lithium refineries and cathode refineries. Were ridiculously vertically integrated. And that’s our best position to protect against supply chain disruptions,” Musk said.
In its update letter, Tesla noted that its lithium refining and cathode production plants are on track to start production this year. The two Tesla refineries will on-shore production of critical battery materials in the United States, an essential task considering Trump’s auto tariffs.
