SpaceX continues to build full-scale Starship hardware at a jaw-dropping pace, testing the limits of rocket production to complete the fifth full-scale prototype in three months and prepare the ship for its first Raptor engine ignition tests.

This time around, SpaceX CEO Elon Musk is fairly confident that the latest Starship prototype – known as serial number 3 (SN3) – has the best chance yet of becoming the first full-scale ship to pass acceptance tests and kick off a Raptor engine static fire campaign. A step further, if said static fires go according to plan, Starship SN3 could become the first full-scale vehicle of its kind to perform controlled flight tests.

Starship SN3 will thus attempt to follow in the footsteps of Starhopper and hopefully avoid an unintentional launch debut similar to the one that destroyed Starship SN1 earlier this month. A successful Starship flight test powered by three Raptor engines would be a major bode of confidence in the upgraded rocket factory SpaceX is building in South Texas. Musk recently made it clear that setting up the machine that builds the machine is currently just as important as individual Starship tests. Thankfully, given that SpaceX is already managing to build colossal rocket prototypes in a matter of weeks for what has to be pennies on the dollar, all with a team of just a few hundred people, the next Starship test campaign is likely just a week or two away.

On March 9th, Musk revealed that the Starship SN2 prototype – an incomplete tank repurposed for specific testing – had passed a proof test with flying colors. SN2’s brief test campaign managed to prove that SpaceX had already fixed the weak point believed to have destroyed Starship SN1 less than two weeks prior. Featuring a redesigned engine section and thrust structure (or “thrust puck,” per Musk), the Starship SN2 test tank survived pressure testing and even made it through engine thrust simulations with the help of an industrial-scale hydraulic jack.

Transformed into a test tank, Starship SN2 successfully passed its proof tests on March 8th, paving the way for SN3+ to aim higher. (NASASpaceflight – bocachicagal)

While the tank passed its tests looking no worse for wear, the last-second design changes SpaceX had to make to rapidly perform thrust structure verification testing made it impossible to repurpose for any alternative use. Starship SN2 has thus been relegated to the scrapyard, a technical necessity but also a sign of both the program’s high rate of progress and low prototype cost. SpaceX’s Boca Chica factory has already more or less completed a new engine section for Starship SN3 and is probably just a day or two away from integrating it with the rest of the steel vehicle.

Less than three days after SpaceX’s brand new vehicle assembly building (VAB) had a single, small Starship section sat inside it, two additional sections of Starship SN3’s tank section departed their fabrication tents and were stacked on March 18th. Less than a day later, the third segment of the rocket’s tank section capped off the two that were stacked the day before. Once those three stacked sections are fully welded together to form a single, cohesive piece of steel, it will need to be stacked atop the aft tank dome and thrust structure to effectively complete Starship SN3’s tank section.

Starship SN3’s thrust structure and aft dome was flipped on March 18th and will likely be ready for installation just a day or two from now. (NASASpaceflight – bocachicagal)

After all four sections are joined, technicians will need to install a few internal parts, but most remaining work mainly involves running wiring and plumbing for power, communications, propellant management, and pressurization. More likely than not, SpaceX replicate its Starship Mk1 and SN1 testing strategy and bring Starship SN3’s tank section to the launch pad for proof testing as soon as outfitting is complete. If the rocket passes proof testing, SpaceX can – for the first time – install functional Raptor engines on a full-scale Starship prototype and begin a crucial wet dress rehearsal (WDR) and static fire test campaign.

At the current rate of progress, SpaceX could easily be ready to transport Starship SN3 to the pad within the next week, give or take. Stay tuned for updates as the company works to quickly finish SN3 integration and move onto the testing phase.

Tesla is about to make parking in busy lots less stressful than ever

Tesla is about to make parking in busy parking lots at businesses and other points of interest less stressful than ever by allowing drivers more control over where they park and how, CEO Elon Musk confirmed on X.

Tesla has been working to improve the parking performance of vehicles utilizing the Full Self-Driving suite, but now it is looking to add more customization, allowing drivers to choose the specific space they park in, but also potentially the orientation the car pulls into the spot:

Musk has reiterated on X twice over the past several weeks that Tesla is working to make things with the FSD suite based more on the driver’s specific preferences and behaviors that were seen in past drives.

Essentially, it sounds like if you tend to park away from a business to avoid other vehicles, Tesla FSD will soon recognize that preference of yours and start parking further away as well. Additionally, the prospect of assigned parking spaces has been something many owners have voiced concerns about.

Living in a community with assigned parking spaces makes using FSD incredibly difficult as it will rarely park in the correct spot when there are so many to choose from. This is also pertinent in work settings where there are sometimes assigned parking spaces.

The updates to Tesla’s Full Self-Driving suite in terms of listening to driver preferences with parking are also extending to routing. Tesla announced yesterday that with the release of its 2026 Summer Update, it was adding Automatic Navigation and Preferred Routes:

Tesla has always maintained the idea that any human input is bad input, and that, ideally, Tesla Full Self-Driving will always make the right decision. Of course, this is all in theory, but the issue is that so many of Tesla’s interventions have come because it does something that is not necessarily wrong, but perhaps not what the driver would prefer.

Taking these preferences into account will help Tesla alleviate some of the potentially unnecessary interventions that drivers perform.

Tesla starts preparing for Optimus in its smartphone app

Published

on

Tesla is starting to prepare for the launch of the Optimus robot in its smartphone app, new coding strings show. Elon Musk has referred to Optimus as what will be the greatest-selling product of any kind of all time, and now, Tesla is getting ready for its launch.

Tesla’s smartphone app had several first-time mentions of the Optimus program, according to Tesla App Updates, who intially reported on the appearance. Here’s what they found:

A Dedicated “Robot” Phone Key Authentication

Tesla is working on a Bluetooth Low Energy, or BLE, authentication that is specifically for robots. This does not only apply to Optimus, though, as Robotaxi, which is Tesla’s autonomous ride-hailing platform, might also identify vehicles within the fleet as robots as well.

Essentially, pairing your phone as a key to anything Tesla identifies as a robot to a “whitelist” of authorized devices. Optimus, Robotaxi, or other products that fall into this category will only respond if the device trying to communicate with it is authorized.

This is a great security feature that will eliminate at least face-value and low-level threats.

Home Data Collection and System Alerts

This appears to be somewhat of a neural network for Optimus within your house. There will be a dedicated screen that asks for consent to collect both video and spatial data while Optimus performs in-home tasks. Everything from vacuuming, washing dishes, dusting, and other activities will be tracked.

There will also be a comprehensive alert system that will track everything from low battery to mechanical issues.

Other Changes

Most of the changes tracked in this particular app update are related to Tesla’s 2026 Summer Update, and include things such as image assets for new features, a preview of the new custom wraps feature, and other unique features.

Tesla Q2 Earnings: Here’s what to expect

Published

on

(Credit: Tesla)

Tesla (NASDAQ: TSLA) will report its earnings for the second quarter of 2026 this evening after market close, and investors and analysts are waiting anxiously to see what the company will report for the second three-month span of the year.

Analysts have already put out their expectations from a financial standpoint for the company’s second quarter, but what’s unknown is what Tesla plans to discuss during the call.

Financial Expectations

Wall Street consensus expectations put Tesla’s Earnings Per Share (EPS) at $0.53, while revenues are expected to come in around $26.4 billion.

This would compare to an EPS of $0.39 and $22.19 billion compared to Tesla’s Q2 2025. Last quarter, EPS came in at $0.41 on $22.387 billion of revenue. Additionally in Q1, Tesla beat analyst expectations, but shares dropped over 3 percent the following trading day.

What We Expect

In terms of discussions, Tesla earnings are pretty sporadic and depend on a handful of things, including current events, investor questions, and more.

Tesla uses a platform called Say to field questions from investors and analysts. These questions are what will be used during the call. Here are the top 5 from the Retail side and top 3 from the Institutional side:

Retail:

“Tesla has missed short-term guidance on robotaxi 3 earnings reports in a row, from 50% coverage of USA by end of 2025 to most recently 7 new cities in 1H26. What is keeping Tesla back from accomplishing these short term goals that they’ve set for themselves?”

“What are the main constraints to expanding robotaxi operations faster, and how do you see that lining up with Cybercab production?”

“What’s the current status of Optimus Gen 3 production ramp, initial deployment in factories, and external sales timeline/volume for 2027? What tasks can we expect the Optimus to perform by end of 2027?”

“To reward long-term Tesla retail shareholders for their loyalty, can you commit to achieving at least half of the goals outlined in your 2025 compensation plan before considering any offers to acquire or merge Tesla?”

“Why has growth of robotaxi vehicles stalled? When will we see cybercab start customer rides?”

Institutional

“Previously, you’ve said Tesla would lead the R&D while SpaceX would lead production for Terafab. Can you provide an update on how that division of responsibilities is evolving, and any additional clarity on the expected capital contributions from Tesla and SpaceX?”

“For autonomous driving, Tesla’s fleet created a huge data advantage by collecting billions of real-world miles. That advantage doesn’t yet exist for Optimus. How should we think about data availability and its impact on Optimus development?”

“Why is it necessary to limit robotaxi operations within specific zones within cities to start? Will every city have to be rolled out this way?”
Tesla will report earnings for Q2 this evening with the Shareholder Deck at 4 p.m. ET, with the call starting around 5:30 p.m. ET.
