SpaceX Starship test tank set for destructive finale after ‘cryo proof’
SpaceX’s fourth Starship test tank is set for a destructive finale after completing a “cryo proof” pressure test on Thursday.
SpaceX’s newest Starship test tank – SN7.1 – is the second in a series of two planned prototypes, both designed to test the viability of using a new steel alloy to build future Starships and Super Heavy boosters. CEO Elon Musk says that SpaceX is technically customizing its own steel alloy for Starship production but Musk’s comments and the results from SN7 testing in June 2020 point towards an offshoot of 304L with minor metallurgical tweaks.
Prior to SN7’s test campaign, Musk revealed that the main goal of the new alloy was to reduce the brittleness of Starship tanks and any adjacent steel components under cryogenic conditions (i.e. extreme cold). Ultimately, SN7 appeared to confirm that the new alloy’s behavior was far more forgiving under cryogenic loads, reaching what were believed to be record pressures before the tank finally burst on June 24th.
Following in SN7’s footsteps, SN7.1 is much closer to an actual Starship prototype.
“SN7.1 is significantly more complex than its sibling and will test a ~304L Raptor mount (thrust puck) and skirt section. The forces and general conditions those new parts will be subjected to are substantially different than most of what SN7 was subjected to, meaning that there is a chance that 304L steel is actually worse in some scenarios.
With any luck, though, SN7.1’s test campaign – scheduled to begin as early as 9pm CDT (UTC-5), September 10th – will be a flawless success, proving that SpaceX’s new steel alloy is superior to 301 for all Starship-related applications. If that’s the case, Starship SN8 – the first full new-alloy prototype – will likely be fully outfitted with a nosecone and header tanks before beginning acceptance testing later this month.”

For SN7.1, increased ductility could theoretically be a mixed bag. Assuming SpaceX has also built the thrust puck out of 304L-adjacent steel, it may end up being too squishy under the extreme forces it will be subjected to. At full throttle, the thrust of three Raptor engines will compress the thrust puck – a cone with dimensions roughly the same as a large circular table – with the equivalent force of a ~600 metric ton (1.3 million lb) weight.
On September 10th, SpaceX put SN7.1 through its paces, performing a cryogenic proof test with liquid nitrogen (LN2) while the tank was still installed on the simple steel frame used to support it during production and transport. That simple decision offers a brief glimpse at the extensive planning that allows SpaceX to optimize for speed and efficiency while still conducting successful tests. While SpaceX could have technically installed SN7.1 directly onto a brand new launch mount custom-built for the exact kind of testing expected, the company instead left the tank on its build stand – much cheaper and far easier to replace than the former.
Technically, moving directly to the launch mount would have slightly simplified the test process, but a tank rupture during a routine cryogenic proof test could have extensively damaged or destroyed the mount, requiring weeks of work to build a full replacement. After SN7.1 successfully completed a cryogenic pressure test on September 10th, SpaceX simply lifted it off its work stand and installed it on a custom-built launch mount.
As early as 9pm CDT (UTC-5) on September 14th, SpaceX will once again load SN7.1 with liquid nitrogen. This time around, the tank – after reaching flight pressures of 7.5 to 8+ bar (110-120+ psi) – will be subjected to the simulated thrust of three Raptor engines by a series of hydraulic rams. Based on a public schedule of road closures, at least two tests are planned. The first will likely put SN7.1 through a range of Raptor thrust scenarios and profiles under the same tank pressures needed for orbital Starship flights. If that test is successful, SpaceX may move SN7.1 back to its work stand before intentionally pressurizing the tank until it bursts sometime around September 17th.

Tesla begins deliveries of its affordable Model Y Standard
The ‘Standard’ Model Y is now getting ready to fall into customer hands, according to some owners, who are preparing for or have already taken delivery of the new model.

Tesla has officially started deliveries of the affordable Model Y ‘Standard’ less than three weeks after the company launched it on October 8.
Following the loss of the $7,500 electric vehicle tax credit, Tesla launched the Model 3 and Model Y ‘Standard’ trims, both coming in at sub-$40,000 starting prices, but being stripped of many of the features that come in the ‘Premium’ configuration levels.
Tesla launches two new affordable models with ‘Standard’ Model 3, Y offerings
The vehicles are Tesla’s answer to the loss of the tax credit, which was phased out by the Trump Administration. Tesla said it has been developing these models for over a year, as it revealed in early 2024 that it was working to create new vehicles that would be more affordable.
It also said it was developing vehicles to be built on a new-generation platform, which is a likely reference to the Cybercab, which has also been spotted at both Gigafactory Texas and the Fremont Factory.

Tesla slated deliveries for November when the two vehicles launched on October 8, but that seems to be an underpromise and overdeliver type of situation.
The new features for the Model Y include:
- New athletically tuned exterior and new alloy wheels to improve aerodynamics
- 15.4″ touchscreen in the front, the same as the other trims
- Available in three colors: Stealth Grey (free), White ($1,oo0 extra), Diamond Black ($1,500 extra)
- Textile and vegan leather interior
- Range sits at 321 miles
- New front fascia
- Covered glass roof (textile on inside)
- Windows are not acoustically laminated for a quieter cabin
- Manual mirrors and seats
- Smaller frunk
- No rear infotainment screen
- No basic Autopilot
- 69 kWh battery
- New 19″ Aperture wheels
- 0-60 MPH in 6.8 seconds
- 7 speaker stereo, down from 15 speakers in premium models

Investor's Corner
Tesla analyst says this common earnings narrative is losing importance
“Numbers are going down next year, but that’s ok because it’s all about autonomy.”

A Tesla (NASDAQ: TSLA) analyst is doubling down on the idea that one common earnings narrative is losing importance as the company continues to work toward new technologies and projects.
This week, Tesla will report earnings for the third quarter, and one thing people always pay attention to is deliveries. Although Tesla reveals its deliveries for the quarter well before it reports earnings, many investors will look for commentary regarding the company’s strategy for responding to the loss of the $7,500 tax credit.
Tesla has made a few moves already, including a lease deal that takes a substantial amount of money off, launching new Standard models, and cutting up to 23 percent off of lease pricing.
Tesla makes crazy move to spur short-term demand in the U.S.
However, analysts are looking at the company in a different light.
Aligning with the narrative that Tesla is not just a car company and has many different projects, Gene Munster of Deepwater Asset Management believes many investors need to look at another part of the business.
Munster said the delivery figures for Q3, which landed at 497,099, the highest in company history, were padded by customers rushing to showrooms to take advantage of the expiring tax credit.
He believes that deliveries will be more realistic in subsequent quarters, but investors should not worry because the focus on Tesla is not going to be on how many cars it hands over to customers:

Tesla has been working nonstop to roll out a dedicated Robotaxi platform in various cities across the United States, and has already launched in two states: Texas and California.
It has also received regulatory approvals to test driverless Robotaxis in Arizona and Nevada, while seeking permissions in Florida and other states, according to the company’s online job postings.
Munster continued:
“Most people are hyper-focused on the Robotaxi opportunity and not focused as much on FSD.”
While Robotaxi is incredibly important, Tesla’s Full Self-Driving (Supervised) suite is also extremely crucial moving forward, as it sets the stage for the company to roll out a formidable self-driving service.
Tesla rolled out its newest FSD software to more owners last night, and as it expands, the company is gaining valuable data to refine its performance.
Earnings will be reported tomorrow at market close.

Tesla rolled out a new feature with FSD v14 to fix a major complaint
One of the most crucial cameras for FSD operation is located at the top of the windshield, and some owners have complained about condensation or other debris accumulating here, which impacts FSD’s availability during drives.

Tesla rolled out a new feature with Full Self-Driving (Supervised) v14.1.3 in an effort to fix a major complaint from owners.
Tesla’s approach to self-driving is significantly different than other companies as it only relies on cameras for operation. Tesla Vision was launched several years ago and completely axed any reliance the suite had on sensors, as CEO Elon Musk’s strategy was unorthodox and went against the grain.
However, it has proven to be effective, as Tesla still operates the most refined semi-autonomous driving suite in the United States.
There are some drawbacks, though, and one of them has to do with the obvious: cameras get dirty and need to be cleaned somewhat regularly.

Tesla has been working to confront this issue, and in classic fashion, it used a software update to work on resolving it.
With the rollout of Full Self-Driving v14.1.3 and Software Version 2025.32.8.15, Tesla added a new feature that aims to clean the front camera efficiently without relying on the owner to do it manually.

In its release notes for the suite, it said:
“Added automatic narrow field washing to provide rapid and efficient front camera self-cleaning, and optimize aerodynamics wash at higher vehicle speed.”
If the camera starts to have some issues with visibility, the car will automatically clean the front windshield camera to avoid any issues:

This new addition is a small but mighty change considering all things. It is a necessary process to keep things operational and avoid any disruptions in FSD performance. It is also a testament to how much better Tesla vehicles can get with a simple software update.
