According to CEO Elon Musk, SpaceX’s Starship and Super Heavy rockets are about to get a new test stand that will enable additional and more useful static fire tests of their Raptor engines.

These modifications could reportedly lead to a simplified engine design and will generally expand SpaceX’s ability to rapidly acceptance-test a huge number of Raptors – a necessity given that each Starship/Super Heavy pair will need up to 43 engines.

Musk’s additional insight came by way of a tweet response to an article published today on NASASpaceflight.com, discussing SpaceX’s recently-unearthed plans to reactivate a test stand that hasn’t seen use in almost half a decade. Known as the tripod stand, the large concrete structure was originally built in the 1990s by Beal Aerospace, a now-defunct spaceflight startup, and came under SpaceX ownership when the company bought the McGregor, Texas facilities in 2003.

SpaceX repurposed the stand to static fire Falcon 9 boosters for a number of years, eventually replacing it with a ground-level installation in 2015 that has since been used to test more than 60 Falcon 9 (and Heavy) boosters. It’s not a huge surprise that SpaceX decided to make the change, given that the tripod stand necessarily placed Falcon boosters several hundred feet off the ground, making what was already a challenge even more arduous (and dangerous) for workers.

NASASpaceflight.com also notes that the stand produced far more noise pollution, encouraging SpaceX to move the replacement stand partially underground.

After four years of inactivity, NASASpaceflight.com photos show that SpaceX is well into the process of refurbishing McGregor’s tripod stand. This time, Musk says it will be modified to support vertical Raptor engine testing, likely requiring a new custom mount and new liquid methane and oxygen propellant farms.

By far the most interesting detail to come out of this development is Musk’s indication that moving Raptor static fires to a vertical stand could actually allow SpaceX to simplify the engine’s design by creating more flight-like test conditions (and thus better data). At the moment, all Raptor acceptance testing is done on a separate test stand located elsewhere at SpaceX’s McGregor facilities. Those stands are horizontal, an engineering decision likely motivated by their relatively cheap and fast construction thanks to sidestepping the need for large, water-cooled thrust diverters.

SpaceX does all of its Merlin Vacuum, Merlin 1D, Falcon 9 booster, and upper stage static fire testing on vertical stands at its McGregor facilities, with Raptor’s horizontal stands being the only exception to the rule. As such, it was likely just a matter of time before SpaceX replaced the horizontal Raptor facilities with vertical stands. Given that SpaceX plans to modify an entirely separate stand to support vertical testing, it’s likely that the company will modify the existing stands to support vertical testing as soon as the tripod stand is up and running.

For Falcon 9 and Heavy, SpaceX has relied on a total of five main engine/vehicle test stands: two for Merlin 1D, one for MVac, one for boosters, and one for upper stages. SpaceX builds engines and rockets in Hawthorne, tests every engine separately in Texas, returns them to Hawthorne, installs them on their respective booster/upper stage, and tests those stages in McGregor before they are shipped to their launch site.

Although that sounds undeniably arduous, the four stands pictured above (plus the F9 booster stand further up) have managed to support the entirety of SpaceX’s 82 launches. A new upper stage test stand is being built, but it has yet to be completed and is only necessary because Falcon 9 upper stages are expendable. According to SpaceX planning documents, Starship and Super Heavy will only perform static fire testing at the launch site. As such, something like the cluster of four Merlin stands above could very likely support the production and testing of 100-200+ Raptor engines annually, enough to build numerous boosters and ships.

SpaceX moves fast, so stay tuned for updates as work continues on the tripod stand and paves the way for even more significant changes at SpaceX’s McGregor, Texas test facilities.

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

Published

on

Credit: Tesla

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.

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.
