Starhopper update: SpaceX’s ungainly Starship testbed survives night of fireballs, Raptor testing

Despite what looked like several decidedly off-nominal fires after an apparently successful Raptor static fire, Starhopper looks unscathed in the morning light. (NASASpaceflight - bocachicagal, 07/17/2019)

SpaceX’s Starhopper appears to have come out the other end of an eventful night of fires, fireballs, and Raptor testing completely unscathed, although – as with all things rocketry – there is vastly more than meets the eye.

However, signs point towards Starhopper being almost entirely unharmed by its brief voyage inside a fireball – even if Boca Chica’s fire suppression system got a thorough workout and many a SpaceX onlooker likely suffered a partial heart attack. For the time being, it’s safe to assume that Starhopper’s planned flight activities have been indefinitely delayed as SpaceX technicians analyze the vehicle and engineers work to mitigate or completely prevent major fires from recurring.

According to NASASpaceflight.com’s well-informed sources, despite the spectacular fireworks that followed Raptor’s own impressive display, the engine’s static fire test was a full success – at least in terms of data produced by the engine. The large fireball was attributed to the ignition of a large methane vent that followed soon after Raptor’s shutdown.

For now, this means that Starhopper’s untethered flight test and hover test debut should not be expected to occur for several days, even in the event that the rocket, pad, and Raptor engine all made it through their July 16th ordeal completely undamaged. If there is zero damage, this accident will serve as an unfortunate but useful demonstration of a true stainless steel rocket’s theoretically exceptional sturdiness and heat resistance.

It may seem more than a little ironic, but it’s likely less than a coincidence. If it comes to fruition as a truly functional, orbit-capable steel rocket, spaceship, and upper stage, Starship/Super Heavy will exist in their shiny, steel forms almost entirely because of the unintuitive tradeoffs that could theoretically make heat-resistant-but-dense steel more efficient than a ship built out of ultra-light carbon composites. If Starhopper’s newly demonstrated resilience is anything to go by, a very happy side-effect of that efficient, heat-resistant steel could be an almost unprecedented resilience in the face of serious fires, fireballs, and other fire-related anomalies.

For almost any other rocket, exposure – at least outside of the engine section – to large fireballs and quite literally having parts burning while motionless on the ground are deeply, deeply worrisome things and risk a major vehicle malfunction – potentially up to and including a catastrophic failure (i.e. explosion). ULA’s Delta IV rocket family is famous for self-immolating during ignition and liftoff, a minimal concern to the rockets’ thin, aluminum tankage thanks to several inches of thick, fire-retardant foam insulation.

For a rocket like Falcon 9, almost entirely (by surface area) composed of thin, aluminum propellant tanks and carbon composite structures, there is a constant struggle to balance the vehicle’s extreme performance with the low melting point of its primary structures (~720 degrees C). The 301-series stainless steel Starhopper and Starship(s) are built out of has a melting point of ~1400 degrees C, nearly double aluminum-lithium alloys.

~12 hours later, Starhopper and Raptor SN06 bare no visible scars after pushing through multiple fires and a large fireball on July 16th. (NASASpaceflight – bocachicagal, 07/17/2019)

In short, while it boggles the mind and is decidedly unintuitive to anyone who watched July 16th’s live coverage of the static fire, it’s actually not a huge surprise that Starhopper has suffered serious fire-related anomalies with essentially zero visible damage. In fact, it’s almost impossible to tell that anything at all happened, let alone discerning some subtle sign(s) of damage incurred by fires. It may sound ironic to say so, but rockets and fire just do not tend to like each other much at all.

Time will tell if Starhopper and Raptor are in as good a condition as they appear to be.

Tesla Semi finally has an FSD timeline and it’s waiting on the Cybercab

Elon Musk told investors Semi self-driving should start working by early 2027, per today’s earnings.

During Wednesday’s’ Tesla Q2 earnings call, an analyst asked Elon Musk when Tesla would look at autonomy for the Semi. His answer set a real timeline for the first time, noting that self-driving on the Tesla Semi is expected to start working “around the end of this year or early next year”.

Musk framed the delay as a matter of priority, not capability. Tesla’s self-driving team is currently focused on Model 3, Model Y, and Cybercab, the vehicles that make up the overwhelming majority of Tesla’s fleet. Since Semi trucks on the road remain a small fraction of that total even after the recent Nevada factory ramp, Musk said it made more sense to keep the software team’s attention on what he called “the march of nines of safety” for the higher volume vehicles first. Autonomous Semi development is “taking a bit of a backseat for the next six months or so,” he said, before adding that it “will definitely be working next year and in time for the scale-up to high production of the Tesla Semi.”

Tesla Semi’s official battery capacity leaked by California regulators

The timeline lines up with what’s already been showing up on public roads. In June, a Tesla Semi was spotted in Sunnyvale wearing a full validation rig, the same rooftop sensor array Tesla mounts on vehicles ahead of an FSD milestone.

A second unit was seen near Fremont days later with a matching camera suite and lens washers. Separately, Tesla analyst Nic Cruz Patane posted video this month of the production Semi’s exterior camera array, ten AI4 based units built directly into the truck rather than added later.


Musk also gave the reason autonomy on the Semi matters in the first place, a persistent shortage of qualified truck drivers. “There is a really serious shortage of truckers,” he said on the call, framing a self-driving Semi as important both for addressing that shortage and for improving safety and comfort for the drivers running the truck today.

The timing also tracks with the Semi’s production reality. Tesla’s Q2 shareholder letter, dropped language promising the Semi would reach volume production this year. Musk pointed to 4680 battery cell output as the near-term constraint on Semi and Cybercab production. A software timeline landing in early 2027 gives Tesla’s autonomy team room to work while the hardware ramp catches up behind it.

It’s worth nothing that this isn’t necessarily a promise the Semi ships driverless next year. Musk’s own language, self-driving “working” by early 2027, describes internal validation catching up to hardware already riding on every production truck, not a public unsupervised rollout.

Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue

Published

on

Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.

The earnings results come after Tesla reported a massive beat on vehicle deliveries for the second quarter, delivering 489,126 vehicles and building 451,758 cars during the three-month span.

This was a major shock for those on Wall Street as they anticipated somewhere around 400,000 deliveries for the quarter, and showed Tesla still has plenty of demand for its vehicles around the world and in the U.S. despite losing the $7,500 EV Tax Credit last year.

Tesla Q2 2026 Earnings Results

  • Non-GAAP EPS – $0.33 reported vs. $0.53 expected
  • Revenues – $28.236 billion reported vs. $26.4 billion expected
  • Free Cash Flow- -$1.092B
  • Profit -$ 4.751B

Tesla (beat/missed) analyst expectations, so the market response to the company’s quarter is what we will look for next.

Tesla shares closed today down just over 1 percent, trading at $374.01.

In the past, it has been anyone’s guess with what Tesla shares will do after they report earnings. Strong quarters have resulted in sharp drops, while lackluster quarters have seen the stock shoot up considerably.

Tesla will hold its Q2 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.

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.
