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.

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 Cybercab uses a unique strategy for picking up the right rider

Published

Tesla Cybercab is using a unique strategy for picking up the correct rider, which is a crucial part of ride-hailing to ensure people end up in the right place and are charged the correct price.

Cybercab will utilize an RGB strip in its front light bar that will illuminate in a variety of different colors to mark itself.

This identifying mark will also appear in the Robotaxi app, giving riders in the same location a notable distinction in an effort to avoid any confusion regarding who should get in each vehicle.

Other ride-hailing services use similar strategies: Lyft and Uber rides are recognizable through driver identity, vehicle type and color, as well as license plate. Waymo will display the rider’s initials on top of the vehicle, letting them know that the specific vehicle for them has arrived.

Tesla’s strategy is unique and interesting, but there are some flaws. Cybercab’s main purpose is aimed toward being an autonomous ride for all, including those who have disabilities like being blind or even color blind.

Tesla will likely have something in the pipeline for those who cannot see colors or have limited vision. There will definitely be multiple ways to identify which vehicle is the one that “you” specifically ordered.

Cybercab is set to start giving public rides next Thursday, September 3, in Austin, as it announced a dedicated event last week and invited many members of the Tesla community.

Tesla ends in-house wrap service that always seemed like a short-term program

Published

Tesla has said goodbye to one customization option for its vehicles: the wrap service it launched several years ago.

After launching an in-house wrap service in August 2020 for the first time in China. In the U.S., it launched in October 2023. Tesla continued to expand the program and adjust it with better pricing and fewer options for the Cybertruck.

By December 2023, it was giving owners of the Model 3, Model Y, and the Cybertruck the opportunity to give their vehicle a fresh look with a vinyl wrap.

It was only available in five locations: Costa Mesa, Oceanside, Santa Clara, West Covina, all in California, and Seattle, Washington.

However, Tesla made some big adjustments to its shop, and the wrap service is officially gone:

Wraps are very popular across the Tesla lineup, especially since the company offers relatively few colors. Many choose to wrap their Teslas with interesting colors, patterns, or even finishes, turning their cars from glossy to satin or matte.

However, Tesla’s wrap service was so limited geographically that it never really had a chance to get off the ground or compete with local shops. Every area in the United States is now overflowing with detailing shops, mobile detailers, and other automotive specialists, many of whom perform wrap services.

Tesla’s service was confined to the Pacific time zone and only spanned across two states. It was never going to be something Tesla was a major competitor in, nor was it going to disrupt the wrapping industry. Now that the program has ended, it seems pretty ideal to believe it was always going to be a short-term thing.

Along with the wrap service, Tesla removed several other products, but nothing too crazy. The Model 3 Door Pocket and Cupholder Liners, the Model S 19″ Magnetite Wheel and Winter Tire Package, Model X/Y Ski/Snowboard Carrier for Hitch Rack, Tesla’s Electric Summer Party Tee, and the Electric Summer Tee were the other items the company totally eliminated from its online shop.

Tesla Robotaxi fleet gets a brain upgrade ahead of Cybercab launch event

Tesla’s Robotaxi service now runs longer hours nationwide as its unsupervised fleet quietly grows larger.

Published

By

Tesla’s Robotaxi service just got easier to catch, with the company’s official Robotaxi account noting that rides are now available from 6 a.m. to 10 p.m., seven days a week, across its operating footprint. The account also said its unsupervised fleet is “a lot bigger” than before, though without specifics. The bigger change is what Tesla says upgraded intelligence in vehicle distribution and routing is what’s actually cutting wait times, not a new Full Self-Driving version.

While Tesla did not name the team behind the upgrade, the language points to its AI and fleet software group rather than the driving stack itself. Vehicle distribution and routing in Robotaxi has functioned mostly as a dispatch problem with the software deciding which idle car goes to which rider, and how far it has to travel to get there. “Upgraded intelligence” suggests a smarter version of that dispatch logic, likely using demand forecasting to position idle cars near where riders are about to request them rather than reacting once a request comes in. Tesla’s AI division has built similar prediction systems for other parts of the business, including the neural networks that power FSD itself, so applying that same approach to fleet logistics would be a natural extension rather than a new discipline for the team.

Tesla is also about a week away from a separate robotaxi milestone. The company plans to launch Cybercab, its purpose built two seat robotaxi with no steering wheel or pedals, in Austin on September 3. Cybercab has been giving employees rides on public and private roads for weeks, and the September event is expected to fold those vehicles into the existing Robotaxi fleet within days of the launch.


Austin previously ran Robotaxi from 6 a.m. to 2 a.m. as of last September, a schedule set before the service expanded into Dallas, Houston, Miami, Tampa, Orlando and the Bay Area. Wednesday’s post did not specify whether that extended overnight window still applies in Austin specifically or whether 6 a.m. to 10 p.m. is now the standard across every market. Tesla’s post, visible on its official Robotaxi account, framed the change simply as fewer riders waiting around for a car.

Whether the wider hours hold once Cybercab enters the fleet next week is the next thing worth watching. Tesla has tended to expand Robotaxi in increments, first geofence, then hours, then fleet size, and each step so far has arrived without much advance notice.
