SpaceX tests Starship and Frankenstein ‘test tank’ simultaneously
After another few weeks of downtime, SpaceX has simultaneously tested the first orbital-class Starship prototype and a Frankenstein-esque ‘test tank’ at its South Texas facilities. While nothing that occurred was all that visually spectacular, the afternoon of testing was still noteworthy for a couple of reasons.
First up, following a successful six-engine Raptor static fire – the first in Starbase history – on November 12th, all signs pointed to Starship S20 attempting another static fire (its fourth) on December 1st. In the almost three weeks of inactivity between those planned tests, SpaceX likely performed extensive inspections of the pathfinder prototype and its Raptor engines. Technicians also repaired the minor heat shield damage and tile loss that testing incurred and patched a few other ‘holes’, effectively leaving Ship 20 with the first fully finished heat shield by the end of November.
Earlier this week, one of the few remaining Boca Chica Village residents received a safety notice from SpaceX indicating that a static fire test was scheduled on Wednesday, December 1st – followed soon after by a notice to mariners (NOTAM) warning boaters to keep to a safe distance. Two hours into the 10am to 6pm CST test window, Starship S20 was already venting and starting to get frosty, confirming that propellant loading had begun. A little over an hour later, it was clear that SpaceX had aborted the first static fire attempt of the day. For the next three hours, Ship 20 exhibited some unusual behavior including new vents, an apparent header tank pressurization or fill test, and still more odd venting in new places.
In the middle of Starship’s weird nose-related testing, SpaceX began simultaneously loading a new ‘test tank’ known as B2.1 with liquid nitrogen (LN2) – marking the first truly simultaneous test of multiple Starship test articles. As Ship 20 seemingly detanked for the second time that day, the B2.1 tank was fully loaded with LN2 and apparently pressure-tested not long after. A few hours later, the test tank was also detanked and the road to the pad was reopened, marking the end of the day’s testing.
Normally, nothing is particularly unusual or noteworthy about test tank testing. Since January 2020, SpaceX has routinely built and tested tanks that are effectively just shorter versions of actual tanks and hardware, using them to qualify changes to Starship’s design, materials, operations, and more before applying those changes to full-size prototypes. B2.1 is the tenth dedicated test tank to reach the launch pad in a little under two years.
Normally, the ‘B2.1’ name SpaceX has given the tank would imply that it’s a newer booster test tank (using Bx instead of BNx) following in the footsteps of BN2.1, which passed cryogenic and load testing this summer. Instead, though, B2.1 is a bit of a nightmarish amalgamation of seemingly random Starship and Super Heavy parts. Its forward dome is an old, unused booster section complete with the hexagonal structure grid fins would have been brace against. Its aft section is a booster thrust structure. Up to that point, it’s effectively just a copy of BN2.1.
However, SpaceX inexplicably installed a Starship thrust dome inside B2.1’s booster thrust structure, creating a test tank with no obvious relevance to any conceivable Starship or Super Heavy design or prototype. Further, SpaceX rolled B2.1 to the launch site for testing only after installing it on an unused device that’s believed to be the aft half of a dedicated booster structural test stand. In theory, a sort of ‘cap’ would be fitted on top of a booster or test tank installed in the stand’s base and strong cables would connect the two, allowing SpaceX to subject prototypes to compressive stress – like, perhaps, the forces a booster might experience while carrying a fully-fueled 1300-ton Starship to space. The upper half of that test structure has yet to be moved to the launch site.
Altogether, the weird half-complete test stand and bizarre fusion of ship and booster parts make B2.1’s purpose and initial testing a complete mystery. It’s unclear what value it provides that makes it more of a priority than, say, finally starting to test the first flightworthy Super Heavy booster (B4). Ultimately, the most interesting thing about B2.1’s test debut is the fact that it appears to mark the first use of Starbase’s brand new orbital tank farm, which is approaching completion.

Elon Musk gives key update on plans for Tesla Diner outside of LA
More Tesla Supercharger Diners are on the way, Elon Musk says, as long as the initial one is successful.

Elon Musk has given a key update on its plans for the Tesla Supercharger Diner, as the first location in Los Angeles is set to open today, July 21.
The idea for the Supercharger Diner, which resembles a 50s-style eatery with elements of futuristic technology, is seven years in the making. Many wondered whether Tesla would expand its idea for a Supercharger restaurant outside of LA, and now we have an answer directly from Musk.
Elon Musk confirms awesome new features at Tesla Diner Supercharger
The Tesla CEO said that the company will establish these types of experiences “in major cities around the world, as well as at Supercharger sites on long distance routes.”
If our retro-futuristic diner turns out well, which I think it will, @Tesla will establish these in major cities around the world, as well as at Supercharger sites on long distance routes.
An island of good food, good vibes & entertainment, all while Supercharging! https://t.co/zmbv6GfqKf

The Supercharger Diner has plenty of ways to draw in customers, and although the food and merchandise sold at the location will not be a major contributor to Tesla’s balance sheet, where investors want to see it, it could pay off in other ways.
The Diner is not exclusive to Tesla owners, so those who drive gas cars can still stop in for a burger, fries, and a shake while roaming around Los Angeles. The features of the Diner, however, do require a Tesla vehicle.
In-car ordering and movie screens syncing to the center touchscreen are two things that Tesla owners will enjoy that other drivers will not. These might be trivial, but the experience on its own could be a way that some consider buying a Tesla.
It might sound crazy that a singular diner experience would flip someone to buy a car, but it’s not the most outlandish thing we’ve ever come across.
The question is where Tesla will plan to build these Supercharger Diners. Musk has already indicated that Starbase, Texas, will be one location, which fits with one of his other companies, SpaceX.
Austin could be an ideal location, but New York, Miami, Washington D.C., Boston, and plenty of other popular metro areas within the U.S. could see their own diners in the coming years.
Investor's Corner
Tesla analyst says this stock concern is overblown while maintaining $400 PT
Tesla reported $2.763 billion in regulatory credit profits last year.

One Tesla analyst is saying that a major stock concern that has been discussed as the Trump administration aims to eliminate many financial crutches for EV and sustainable industries is overblown.
As the White House continues to put an emphasis on natural gas, coal, and other fossil fuels, investors are concerned that high-powered sustainability stocks like Tesla stand to take big hits over the coming years.
However, Piper Sandler analyst Alexander Potter believes it is just the opposite, as a new note to investors released on Monday says that the situation, especially regarding regulatory credits, is “not as bad as you think.”
Tesla stacked emissions credits in 2023, while others posted deficits
There have been many things during the Trump administration so far that have led some investors to consider divesting from Tesla altogether. Many people have shied away due to concerns over demand, as the $7,500 new EV tax credit and $4,000 used EV tax credit will bow out at the end of Q3.
The Trump White House could also do away with emissions credits, which aim to give automakers a threshold of emissions to encourage EV production and cleaner powertrains. Companies that cannot meet this threshold can buy credits from other companies, and Tesla has benefitted from this program immensely over the past few years.
As the Trump administration considers eliminating this program, investors are concerned that it could significantly impact Tesla’s balance sheet. Potter believes the issue is overblown:
“We frequently receive questions about Tesla’s regulatory credits, and for good reason: the company received ~$3.5B in ‘free money’ last year, representing roughly 100% of FY24 free cash flow. So it’s fair to ask: will recent regulatory changes threaten Tesla’s earnings outlook? In short, we think the answer is no, at least not in 2025. We think that while it’s true that the U.S. government is committed to rescinding financial support for the EV and battery industries, Tesla will still book around $3B in credits this year, followed by $2.3B in 2026. This latter figure represents a modest reduction vs. our previous expectation…in our view, there’s no need for drastic estimate revisions. Note that it’s difficult to forecast the financial impact of regulatory credits — even Tesla itself struggles with this — but the attached analysis represents an honest effort.”
Tesla’s regulatory credit profitability by year is:
- 2020: $1.58 billion
- 2021: $1.465 billion
- 2022: $1.776 billion
- 2023: $1.79 billion
- 2024: $2.763 billion
Potter and Piper Sandler maintained an ‘Overweight’ rating on the stock, and kept their $400 price target.
Tesla shares are trading at $329.63 at 11:39 a.m. on the East Coast.

Tesla rolls out update to Robotaxi service that makes pickups so much better
The update was confirmed by CEO Elon Musk in a post on social media platform X.

Tesla has rolled out a minor update to its Robotaxi service that will likely make the driverless ride-hailing system notably better and more convenient for consumers. The update was confirmed by CEO Elon Musk in a post on social media platform X.
Robotaxi service updates
The Robotaxi update was observed by users of the driverless ride-hailing service over the weekend. As observed by Tesla enthusiast Owen Sparks, the Austin Robotaxi fleet no longer strictly navigates to the pickup point listed on the app. Instead, the Robotaxis now stop in the exact location of a user’s phone.
Elon Musk confirmed the update, noting in a post on X that the change was an upgrade to the service. It’s a reactively minor update in the grand scheme of things, but it should make the Robotaxi service feel more organic and humanlike.
Driverless taxis
Tesla’s Robotaxi service in Austin has been receiving good reviews from users since it was launched, with many praising the vehicles for their cautious and humanlike behavior. Some users on social media even noted that Tesla’s Robotaxis feel safer on the road than cars from services like Uber, which are manually driven.
Tesla’s minor updates to its Robotaxi service are expected to make the customer experience of the driverless ride-hailing service more refined. By doing so, Tesla could ease customers into its service, even if only a fraction of ride-hailing users are familiar with fully autonomous cars. With this in mind, even small updates like picking up customers based on their specific phone location will likely go a long way towards making Tesla’s Robotaxis more accepted by the general public.
