What’s causing SpaceX’s Falcon Heavy delays?
Although uncertainty in the schedule remains, SpaceX’s Falcon Heavy rocket appears to be nearly ready for its first engine ignition test (called a ‘static fire’) sometime within the next week or so.
An attempt at 1 PM EST today, January 16, was canceled for unspecified reasons, although Kennedy Space Center reportedly maintained the usual roadblock to prevent vehicles from driving past, implying that SpaceX still intends to conduct propellant loading tests with Falcon Heavy. It was noted earlier this morning by spaceflight journalist Chris Bergin that things were “a bit too quiet” if a test was indeed planned for today, and his intuition appears to have been correct. It still remains the case that Falcon Heavy is an experimental and untested rocket to an extent, and these delays are to be expected as SpaceX works out the inevitable kinks and bugs that arise during the extensive testing big launch vehicle has been and is still being put through.
KSC is in roadblock stance, so they will still do some testing it would seem, but we will have to wait for the Static Fire itself. https://t.co/DxzsRn85NR

Due to range requirements in support of an upcoming launch of the United Launch Alliance’s (ULA) Atlas 5 rocket, currently NET Thursday, SpaceX has postponed the static fire of Falcon Heavy without a replacement date. It is unlikely that another attempt will occur before the upcoming weekend, but SpaceX should have at least a solid week of uninterrupted range support once ULA’s launch occurs, hopefully without delay. Godspeed to ULA, in the meantime.
The crazy complexity of rocketry
Most recently, and perhaps somewhat related to Falcon Heavy’s static fire delays, SpaceX completed as many as two complete wet dress rehearsals (WDRs), which saw Falcon Heavy topped off with full tanks of its cryogenic (super cool) liquid oxygen (LOX) and rocket-grade jet fuel (RP-1). In essence, the rocket became equivalent to several hundred tons of carefully stabilized explosive. Nominally, these rehearsals appear entirely uneventful to an outside observer, with little more than ice formation and the occasional bursts of propellant tank vents to suggest that something important is occurring. However, anomalies like the failure of Falcon 9 during the Amos-6 static fire provide a staggering demonstration of just how explosive and sensitive a rocket’s fuel is, and Falcon Heavy has approximately three times the fuel capacity of Falcon 9. Empty, Falcon 9’s mass has been estimated to be around 30 metric tons, a minuscule amount of structure in the face of the more than 500 metric tons of propellant the vehicle carries at liftoff.
These propellant loading tests can also be challenging for reasons aside from their highly explosive nature. Due to basic realities of the physical nature of metal, the predominate ingredient for Falcon 9’s load-bearing structures, metallic structures shrink under extreme cold (and expand under heating). In the case of Falcon 9’s massive 45 meters (150 foot) tall first stage, the scale of this contraction can be on the order of several inches or more, particularly given SpaceX’s predilection towards cooling their propellant as much as possible to increase its energy density. For Falcon 9, these issues (thermodynamic loads) are less severe. However, add in three relatively different first stage boosters linked together with several extremely strong supports at both their tops and bottoms and that dynamic loading can become a fickle beast. The expansion or compression of materials due to temperature changes can create absolutely astounding amounts of pressure – if you’ve ever forgotten a glass bottled drink in the freezer and discovered it violently exploded at some future point, you’ll have experienced this yourself.
With several inches of freedom and the possibility that each Falcon Heavy booster might contract or expand slightly differently, these forces could understandably wreak havoc with the high precision necessary for the huge rocket to properly connect with the launch pad’s ground systems that transmit propellant, fluids, and telemetry back and forth. Information from two reliable Kennedy Space Center sources experienced with the reality of operating rockets, as well as NASASpaceflight.com, suggested that issues with dynamic loads (such as those created by thermal contraction/expansion) are a likely explanation for the delays, further evidenced by their observations that much of the pad crew’s attention appeared to be focused at the base of Transporter/Erector/Launcher (TEL). The TEL base hosts the clamps that hold the rocket down during static fires and launches, as well as the Tail Service Masts (TSMs) that connect with the Falcon 9/Heavy to transport propellant and data to the first stage(s). These connection points are both relatively tiny, mechanically sensitive, and absolutely critical for the successful operation of the rocket, and thus are a logical point of failure in the event of off-nominal or unpredicted levels of dynamic stresses.

Test, launch, land, repeat.
All things considered, these difficulties demonstrate that even after months (even years) of relentless modeling, testing, remodeling, and retesting, rockets (and especially huge rockets like Falcon Heavy) are immensely complex, and even tiny mistakes can lead the vehicle to stray from its expected behavior. Quite simply, the reality of engineering only truly comes into play once hardware is fully in the loop, and it’s in this state that SpaceX has demonstrated again and again a distinct and elegant ability to learn from their hardware, rather than attempt to salve uncertainty with a neurotic and counterproductive level of statistical analysis, modelling, and documentation. The agile launch company still dabbles in those aspects when beneficial or necessary, but testing comes first in its importance.
The conclusion here, then, is that Falcon Heavy’s delays betray this aspect of SpaceX – a launch company that loves its fans, but also understands the need for cautious testing when it comes to new and untried rocket hardware. Whether Falcon Heavy succeeds or fails, SpaceX will learn from the proceedings, and they will be better off for it (although maybe less so financially…).

Tesla ‘Model Q’ gets bold prediction from Deutsche Bank that investors will love
Tesla’s Model Q could be on the way soon, and a new note from Deutsche Bank thinks it will contribute to Q4 deliveries.
The Tesla “Model Q” has been in the rumor mill for the company for several years, but a recent note from Wall Street firm Deutsche Bank seems to indicate that it could be on its way in the near future.
This comes as Tesla has been indicating for several quarters that its development of affordable models was “on track” for the first half of 2025. The company did not say it would unveil the vehicles in the first half, but many are anticipating that more cost-friendly models could be revealed to the public soon.
Potential affordable Tesla “Model 2/Model Q” test car spotted anew in Giga Texas
The Deutsche Bank note refers to one of the rumored affordable models as the “Model Q,” but we’ve also seen it referred to as the “Model 2,” amongst other names. Tesla has not officially coined any of its upcoming vehicles as such, but these are more of a universally accepted phrase to identify them, at least for now.
The rumors stem from sentiments regarding Tesla’s 2025 delivery projections, which are tempered as the company seeks to maintain a steady pace compared to 2023 and 2024, when it reported 1.8 million deliveries.
Deutsche Bank’s analysts believe the deliveries could be around 1.58 million, but they state this is a cautious stance that could be impacted by several things, including the potential launch of the Model Q, which they believe will make its way to market in Q4:
“Looking at the rest of the year, we maintain a cautious stance on volume calling for 1.58m vehicle deliveries (-12% YoY) vs. consensus +1.62m, with the timing of Model Q rollout as the key swing factor (we now assume only 25k in Q4). In China, Tesla will introduce the Model Y L this fall (6 inch longer wheel base allowing for larger 3-row seating with six seats).”
Interestingly, the same firm also predicted that the Model Q would launch in the first half of the year based on a note that was released in early December 2024.
Those estimations came from a reported meeting that Deutsche Bank had with Tesla late last year, where it said it aimed to launch the Model Q for less than $30,000 and aimed for it to compete with cars like the Volkswagen ID.3 and BYD Dolphin.
Tesla’s Q2 Earnings Call is slated for this Wednesday and could reveal some additional details about the affordable models.

Tesla preps to expand Robotaxi geofence once again, answering Waymo
Just days after Waymo responded to them, Tesla is preparing for a potentially massive expansion of the Robotaxi geofence.
Tesla is preparing to expand its Robotaxi geofence yet again, just days after Waymo responded to its initial broadening of the area.
Tesla launched its first expansion last week, less than a month after introducing Robotaxi rides in Austin.
The company opted for a very interesting shape for its geofence expansion, which was more of an indication that it could launch more rides in virtually any area of the city due to the new geofence it chose.
Waymo then responded to Tesla shortly after with an expansion of its own. After Tesla’s first expansion of its geofence, it had 42 square miles of Robotaxi-accessible travel region. This was larger than Waymo’s 37 square miles.
However, the Waymo expansion last week brought the company to a substantial 90 square miles of Austin:
Waymo responds to Tesla’s Robotaxi expansion in Austin with bold statement
Tesla appears to be ready to respond. Drone operator and Gigafactory Texas observer Joe Tegtmeyer spotted Tesla Robotaxi validation vehicles well west of downtown Austin in the area of Marble Falls, Texas.
This would significantly increase Tesla’s square mileage if it could manage to bring its geofence to that size:
🚨 We could see Tesla’s response to Waymo’s expansion in Austin very soon
Based on Tesla’s expansion last time, it’s safe to assume they can go to any area of Austin whenever they choose
It’s not a coincidence they chose, well, you know, the shape they did 🤣 https://t.co/xB92SQ1ntC

The two companies are not directly responding to one another with these expansions, but it appears that there is a significant amount of competition underway, which ultimately benefits the consumers.
Waymo has been operating in Texas since March from a fully public perspective, while Tesla is still slowly expanding its test size for the Robotaxi fleet on a nearly daily basis. Tesla launched Robotaxi rides to a handful of Early Access Program members on June 22.
Tesla is also expanding to other regions of the United States, particularly in Arizona and California. However, the Texas expansion is a priority currently, as it is the only region where Tesla has received approval to operate passenger rides in a driverless setting in the country.

Elon Musk confirms awesome new features at Tesla Diner Supercharger
More details continue to be revealed about the Tesla Supercharger Diner as its opening seems to be imminent.
Elon Musk has confirmed a few new features that will be present at the Tesla Diner Supercharger in Los Angeles.
Musk confirmed these two new details as he revealed he recently ate at the Supercharger Diner. We also recently confirmed a few menu items as a soft launch has already occurred, and a public launch date appears to be within reach.
The new features were revealed by Tesla Joy on X. We shared the details, and Musk confirmed that these are, in fact, features of the Diner that Tesla owners will be able to enjoy.
Tesla reveals key detail of Supercharger Diner, but it’s bigger than you think
The Diner is not exclusive to Tesla owners, but these two features do require a Tesla for compatibility purposes.
Order Food from Your Car
As you pull into the Supercharger Diner, you can order any food item you want, including burgers, wings, fries, shakes, cookies, and more, directly from your vehicle.
A prompt will likely appear that will open a menu to the Supercharger Diner, allowing you to order food. An employee will bring the food out, that is, if Tesla decides to continue with a true and traditional 50s diner theme.
We get it, it’s not a groundbreaking feature. It’s still cool, convenient, and another advantage to visit the diner as a Tesla owner.
Movie Screen Audio Will Sync to Your Tesla
There are two massive movie screens that will play various entertainment options during your visit to the Supercharger Diner. There have been movie clips and even SpaceX launch highlights playing during recent drone flyovers at the location on Santa Monica Boulevard.
Instead of having to open your windows to hear the content on the screen, it will instead sync the audio and play directly in your vehicle through your car stereo speakers.

The Supercharger Diner has also appeared on the Tesla app for the first time, and is currently showing 80 stalls at the location:
🚨 The Tesla Diner is now showing up on the phone app.

— TESLARATI (@Teslarati) July 18, 2025
Although the stalls are not yet active, the culmination of all the details we’ve learned over the past week about the Diner only points to one thing: an imminent grand opening.
Tesla has not yet confirmed a date for the Supercharger Diner’s opening, and Los Angeles building and construction permits also do not state a specific target date for opening.
It seems as if Tesla will reveal the date itself, potentially in the coming week, as it will report earnings on Wednesday, July 23.
