SpaceX sends Starship heat shield “bakery” to Boca Chica

(NASASpaceflight - bocachicagal)

At the same time as SpaceX is assembling hardware and manufacturing dozens of Raptor engines for Starship’s inaugural orbital test flight, it’s also preparing for what will follow.

Last week, a local photographer captured photos of one of the many dozens of deliveries that arrive at SpaceX’s Boca Chica Starship factory every month – notable this time around because of package labels that reference a “heat shield” and “mini bakery.” In any other case, it would’ve been just another nondescript delivery – likely carrying the latest batch of the ceramic Starship heat shield tiles SpaceX currently manufactures in Cocoa Beach and Cape Canaveral, Florida.

However, as the photographer (@StarshipGazer) that captured the images noted, that Florida Starship heat shield factory just so happens to be colloquially known as “The Bakery” by the SpaceX team that runs it.

As the nickname would suggest, The Bakery is one of two main Florida-based facilities tasked with turning raw materials into the black, hexagonal heat shield tiles that have begun to spread across the exterior of Starship prototypes. The June 7th delivery of a “mini bakery” strongly implies that SpaceX has now begun to build out some limited capacity for heat shield tile production at Boca Chica itself – under the main Starship factory roof, in other words.

While the number of tiles present has only really begun to grow in the last six or so months, SpaceX has been building, testing, and refining Starship’s heat shield technology for more than two years. SpaceX’s custom-built ceramic tiles made their first public appearances in July and August 2019, first launching into orbit on a Cargo Dragon spacecraft and later tagging along on Starhopper’s spectacular 150m (~500 ft) hop a few weeks later. Dragon went on to reenter and splash down in the Pacific Ocean without issue about a month later, effectively marking the first successful orbital reentry of (part of) a Starship heat shield.

With Starship SN8 heralding the arrival of full-size prototype flight tests in the last few months of 2020, SpaceX began to substantially increase the number of tiles installed on Starships, jumping from a handful to hundreds within a few months. Although Starship SN15’s successful May 5th, 2021 launch and landing likely means it will never fly, Starship SN16 was outfitted with more than a thousand tiles (and SN15 flew with almost as many). While those tiles have essentially zero experience acting as a heat shield on Starship prototypes, launching them on suborbital test flights still subjects those heat shield installations to major thermal and mechanical stresses similar to (or worse than) what Starship will need to withstand during launch and after reentry.

Given that at least a few of the ceramic tiles installed on each prototype have invariably shattered at some point during testing, it’s unclear exactly how successful those coupon tests have been. Unlike the Space Shuttle, which also relied almost exclusively on catastrophically fragile ceramic heat shield tiles, Starship’s tiles are mounted directly to its hull and that hull is made out of steel instead of an aluminum frame. In theory, Starship’s structure can thus withstand – and remain functional – at temperatures approaching 800°C (1500°F), whereas the Shuttle’s heat shield had to keep the vehicle’s aluminum structure below ~180°C (360°F).

Of course, Starship has yet to even attempt to survive an orbital-velocity reentry with some 10,000 ceramic heat shield tiles mounted directly to its steel skin. If successful, SpaceX’s ultra-simple design could give Starship massive advantages over the Shuttle, which ultimately proved to be more dangerous than traditional crew capsules and about as expensive as a similarly capable expendable rocket. But Starship’s heat shield has its work cut out for it to prove that the vast spacecraft is truly up to the challenge of orbital reentry and safe, reliable reuse.

Tesla has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.

The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.

The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.

The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.

It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”

Tesla has used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.

It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing

The Robotaxi suite has continued to improve, and this week, vehicles were spotted in Austin without any occupants. CEO Elon Musk would later confirm that Tesla had started testing driverless rides in Austin, hoping to launch rides without any supervision by the end of the year.

Tesla stock closes at all-time high on heels of Robotaxi progress

Tesla stock (NASDAQ: TSLA) closed at an all-time high on Tuesday, jumping over 3 percent during the day and finishing at $489.88.

The price beats the previous record close, which was $479.86.

Shares have had a crazy year, dipping more than 40 percent from the start of the year. The stock then started to recover once again around late April, when its price started to climb back up from the low $200 level.

This week, Tesla started to climb toward its highest levels ever, as it was revealed on Sunday that the company was testing driverless Robotaxis in Austin. The spike in value pushed the company’s valuation to $1.63 trillion.

It is the seventh-most valuable company on the market currently, trailing Nvidia, Apple, Alphabet (Google), Microsoft, Amazon, and Meta.

Shares closed up $14.57 today, up over 3 percent.

The stock has gone through a lot this year, as previously mentioned. Shares tumbled in Q1 due to CEO Elon Musk’s involvement with the Department of Government Efficiency (DOGE), which pulled his attention away from his companies and left a major overhang on their valuations.

However, things started to rebound halfway through the year, and as the government started to phase out the $7,500 tax credit, demand spiked as consumers tried to take advantage of it.

Q3 deliveries were the highest in company history, and Tesla responded to the loss of the tax credit with the launch of the Model 3 and Model Y Standard.

Additionally, analysts have announced high expectations this week for the company on Wall Street as Robotaxi continues to be the focus. With autonomy within Tesla’s sights, things are moving in the direction of Robotaxi being a major catalyst for growth on the Street in the coming year.

Tesla needs to come through on this one Robotaxi metric, analyst says

“We think the key focus from here will be how fast Tesla can scale driverless operations (including if Tesla’s approach to software/hardware allows it to scale significantly faster than competitors, as the company has argued), and on profitability.”

Tesla needs to come through on this one Robotaxi metric, Mark Delaney of Goldman Sachs says.

Tesla is in the process of rolling out its Robotaxi platform to areas outside of Austin and the California Bay Area. It has plans to launch in five additional cities, including Houston, Dallas, Miami, Las Vegas, and Phoenix.

However, the company’s expansion is not what the focus needs to be, according to Delaney. It’s the speed of deployment.

The analyst said:

“We think the key focus from here will be how fast Tesla can scale driverless operations (including if Tesla’s approach to software/hardware allows it to scale significantly faster than competitors, as the company has argued), and on profitability.”

Profitability will come as the Robotaxi fleet expands. Making that money will be dependent on when Tesla can initiate rides in more areas, giving more customers access to the program.

There are some additional things that the company needs to make happen ahead of the major Robotaxi expansion, one of those things is launching driverless rides in Austin, the first city in which it launched the program.

This week, Tesla started testing driverless Robotaxi rides in Austin, as two different Model Y units were spotted with no occupants, a huge step in the company’s plans for the ride-sharing platform.

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing

CEO Elon Musk has been hoping to remove Safety Monitors from Robotaxis in Austin for several months, first mentioning the plan to have them out by the end of 2025 in September. He confirmed on Sunday that Tesla had officially removed vehicle occupants and started testing truly unsupervised rides.

Although Safety Monitors in Austin have been sitting in the passenger’s seat, they have still had the ability to override things in case of an emergency. After all, the ultimate goal was safety and avoiding any accidents or injuries.

Goldman Sachs reiterated its ‘Neutral’ rating and its $400 price target. Delaney said, “Tesla is making progress with its autonomous technology,” and recent developments make it evident that this is true.
