SpaceX Starship pop test opens the door for 60,000 foot hop [update]
SpaceX has successfully destroyed a Starship ‘test tank’ for the fourth time, opening the door for the first high-altitude prototype to roll to the launch pad as soon as tomorrow.
The culmination of three nights and more than 20 hours of concerted effort, SpaceX was finally able to fill Starship test tank SN7.1 with several hundred tons of liquid nitrogen before dawn on September 23rd. With just an hour left in the day’s test window, SpaceX closed the tank’s vents, allowing its cryogenic contents to boil into gas and expand with no outlet. At 4:57 am CDT, SN7.1 burst, bringing its lengthy test campaign to a decisive end.
A handful of hours later, new road closure notices revealed SpaceX’s plan to roll Starship SN8 – the first full-size prototype and first ship meant for high-altitude testing – from its Boca Chica factory to the launch site.
Update: All road closures planned for Starship SN8’s roll to the launch pad (Sept 24) and first test campaign (Sept 27-29) have been canceled. Stay tuned for updates on the high-altitude prototype’s test schedule.
Short of new information from SpaceX or CEO Elon Musk, little is known about the results of SN7.1’s lengthy test campaign, but the fact that it survived two nights of nondestructive testing – including the use of hydraulic rams to simulate Raptor thrust – effectively clears Starship SN8 for suborbital testing. Based on a speculative, amateur analysis of the aftermath of SN7.1’s burst test, it can also be tentatively concluded that the tank failed almost exactly where one would expect it to: the in-situ weld attaching the upper tank dome to SN7.1’s steel ring hull.
SN7.1’s forward dome appears to have cleanly sheared off around much of its circumferential weld joint – exactly what one would theoretically expect from a good, uniform weld. Assuming that SN7.1 reached pressures well above 8.5 bar (~125 psi) before it burst, the tank’s final test can likely be deemed a success.
The very same day SpaceX kicked off what would become Starship SN7.1’s last burst test attempt, teams worked to install functional flaps on a full-scale Starship prototype (SN8) for the first time ever. Effectively answering the question of whether SpaceX would fully outfit the ship with a nosecone and flaps before its first acceptance tests, SN7.1’s successful pop was followed by road closure notices for SN8’s transport to the launch pad around dawn on September 24th and cryptic “SN8 Testing” as early as September 27th.
As of September 23rd, SN8’s twin aft flaps – large aerodynamic control surfaces meant to stabilize free-falling Starships – have been fully installed alongside ‘aerocovers’ that will protect each flap’s control mechanisms. The only hardware Starship SN8 is missing is a ~20m (~60 ft) tall nosecone, two smaller forward flaps, and the plumbing needed to access a smaller liquid oxygen “header” tank located in the tip of said nose.
At the moment, SpaceX has installed one Starship nosecone prototype atop five unpressurized rings – creating a full nosecone stack. That particular prototype has no liquid oxygen header tank, however, meaning that SpaceX would likely need at least a day or two to weld one of the noses with a header tank atop one of several finished five-ring sections. In other words, to transport SN8 to the pad tomorrow, there’s almost no chance that SpaceX will have time to finish and install a proper nosecone on the prototype, meaning that the company has chosen to test the Starship before that milestone.
Doing so should reduce any inconvenience caused by vehicle failure in the event that Starship SN8’s acceptance test campaign doesn’t go as planned. In hindsight, the inclusion of Starship SN8’s aft flaps and aerocovers during the ship’s first major tests was likely a necessity, given that almost half of each flap and its support structure is installed directly to the skin of its liquid oxygen tank. Theoretically, when chilled to the temperature of liquid nitrogen or oxygen, the diameter of the stainless steel rings Starship SN8 is built out of could shrink by as much as 0.3% (~20 mm or ~0.8 in).
Only half of Starship SN8’s aft flaps will be directly subject to that tank contraction, resulting in a relatively complex environment for such a large, high-stress mechanical system. As such, testing flap actuation under cryogenic loads is likely a critical part of SN8’s cryogenic proof test, otherwise meant to demonstrate the structural integrity and functionality of Starship’s propellant tanks. If SN8 rolls to SpaceX’s launch facilities on schedule, the Starship’s first cryogenic proof test could begin as early as 9pm CDT (UTC-5) on Sunday, September 27th.

Tesla received a price target boost from Morgan Stanley, according to a new note on Monday morning, but there is some considerable caution also being communicated over the next year or so.
Morgan Stanley analyst Andrew Percoco took over Tesla coverage for the firm from longtime bull Adam Jonas, who appears to be focusing on embodied AI stocks and no longer automotive.
Percoco took over and immediately adjusted the price target for Tesla from $410 to $425, and changed its rating on shares from ‘Overweight’ to ‘Equal Weight.’
Percoco said he believes Tesla is the leading company in terms of electric vehicles, manufacturing, renewable energy, and real-world AI, so it deserves a premium valuation. However, he admits the high expectations for the company could provide for a “choppy trading environment” for the next year.
He wrote:
“However, high expectations on the latter have brought the stock closer to fair valuation. While it is well understood that Tesla is more than an auto manufacturer, we expect a choppy trading environment for the TSLA shares over the next 12 months, as we see downside to estimates, while the catalysts for its non-auto businesses appear priced at current levels.”
Percoco also added that if market cap hurdles are achieved, Morgan Stanley would reduce its price target by 7 percent.
Perhaps the biggest change with Percoco taking over the analysis for Jonas is how he will determine the value of each individual project. For example, he believes Optimus is worth about $60 per share of equity value.
He went on to describe the potential value of Full Self-Driving, highlighting its importance to the Tesla valuation:
“Full Self Driving (FSD) is the crown jewel of Tesla’s auto business; we believe that its leading-edge personal autonomous driving offering is a real game changer, and will remain a significant competitive advantage over its EV and non-EV peers. As Tesla continues to improve its platform with increased levels of autonomy (i.e., hands-off, eyes-off), it will revolutionize the personal driving experience. It remains to be seen if others will be able to keep pace.”
Additionally, Percoco outlined both bear and bull cases for the stock. He believes $860 per share, “which could be in play in the next 12 months if Tesla manages through the EV-downturn,” while also scaling Robotaxi, executing on unsupervised FSD, and scaling Optimus, is in play for the bull case.
Will Tesla thrive without the EV tax credit? Five reasons why they might
Meanwhile, the bear case is placed at $145 per share, and “assumes greater competition and margin pressure across all business lines, embedding zero value for humanoids, slowing the growth curve for Tesla’s robotaxi fleet to reflect regulatory challenges in scaling a vision-only perception stack, and lowering market share and margin profile for the autos and energy businesses.”
Currently, Tesla shares are trading at around $441.

Tesla Optimus dramatically collapses after teleoperator mishap
It seemed blatantly obvious that whoever was controlling the Optimus robot from behind the scenes did not disconnect their ability to manipulate its movements
Tesla Optimus dramatically collapsed after a teleoperator mishap at the company’s “Future of Autonomy Visualized” event in Miami this past weekend.
It seemed blatantly obvious that whoever was controlling the Optimus robot from behind the scenes did not disconnect their ability to manipulate its movements, then left the controls, causing Optimus to collapse.
A video captured at the event shows Optimus doing a movement similar to taking a headset off, likely what the teleoperator uses to hear guest requests and communicate with other staff:

After the headset removal motion was completed, Optimus simply collapsed backward, making for an interesting bit of conversation. While it was a mishap, it was actually pretty funny to watch because of the drama displayed by the robot in the situation.
This was obviously a mistake made by the teleoperator, and does not appear to be a spot where we can put any sort of blame on Optimus. It would have likely just stood there and waited for controls to resume if the teleoperator had disconnected from the robot correctly.
However, details are pretty slim, and Tesla has not announced anything explaining the situation, likely because it seems to be a pretty face-value event.
Tesla Optimus shows off its newest capability as progress accelerates
The Tesla Optimus program has been among the most hyped projects that the company has been working on, as CEO Elon Musk has extremely high hopes for what it could do for people on Earth. He has said on several occasions that Optimus should be the most popular product of all time, considering its capabilities.
Obviously, the project is still a work in progress, and growing pains are going to be part of the development of Optimus.
In its development of Optimus Gen 3, Tesla has been working on refining the forearm, hand, and fingers of Optimus, something that Musk said is extremely difficult. However, it’s a necessary step, especially if its capabilities will not be limited by hardware.
All in all, Optimus has still been a very successful project for Tesla, especially in the early stages. The company has done an excellent job of keeping Optimus busy, as it helps with serving customers at events and the Tesla Diner, and is also performing tasks across the company’s manufacturing plants.
Tesla has finally announced the features for the 2025 Holiday Update, which includes a wide variety of new inclusions that are both functional and just for fun.
The new features are plentiful, but there were a handful of things we were expecting to see based on what we know. We don’t want to sound ungrateful, because there are a lot of great new things on the way with this update.
Here’s what was included:
Grok with Navigation Commands (Beta)
Grok will now have the ability to add and edit navigation destinations, which is a drastic improvement considering Tesla owners had to use their standard voice commands for this in the past.
The utilization of Grok will likely improve the navigation experience by offering some insight into your destination, including reviews and other points of interest nearby.
It will be enabled by using Grok’s “Assistant” personality.
Tesla Photobooth
“Turn your car into a photobooth! Take selfies from inside your Tesla & give yourself a makeover with fun filters, stickers, and emojis. Share with others right from the Tesla app.”
This feature will be available within the Toybox.
Dog Mode Live Activity
When using Dog Mode to keep your four-legged friend comfortable in the car, you’ll now be able to check in on them as it will share periodic snapshots of the cabin, along with live updates on temperature, battery, and climate conditions.
Dashcam Viewer Update
Dashcam clips are awesome, but they’re void of a lot of information, which could be useful in some instances, especially if there is an accident.
Now, there will be additional details included on each Dashcam clip, like speed, steering wheel angle, and Self-Driving state.
Santa Mode
New graphics, trees, and a lock chime are now available.
Light Show Update
A new Light Show, called Jingle Rush, will be available.
Custom Wraps and License Plates in Colorizer
Colorizer will now be known as “Paint Shop” in the Toybox. You will now be able to personalize your Tesla Avatar with window tints, custom wraps, and license plates. Preloaded designs will be available, but owners will be able to use their USB Flash Drives to create one that suits their style.
Navigation Improvements
Changing the order of your destinations will be easier through a new “Favorites” tab, and Home and Work can now be set by dropping a pin.
There will also be “Suggested Destinations,” which will be determined through recent trips and habits while parked.
Supercharger Site Map
Perhaps the most significant feature of the Holiday Update, Tesla is adding a 3D view of select Tesla Superchargers by tapping “View Site Map.”
When navigating to a location with this capability, the site layout, live occupancy, and nearby amenities will be available. Drivers will also be able to choose which stall to Supercharge.
This is only available at a handful of locations currently, but it will expand to more Superchargers as it becomes more robust.
Automatic Carpool Lane Routing
Navigation will include an option to utilize carpool lanes. Your route will automatically choose the carpool lane when eligible.
Phone Left Behind Chime
If the in-car occupant detection system does not see anyone in the car and there is a phone key, or if a phone is left inside the cabin, your Tesla will chime a few seconds after the doors close.
Charge Limit Per Location
You can now save a charge limit for the current location while parked and it will be applied automatically the next time you charge there.
ISS Docking Simulator
In a SpaceX collaboration, Tesla has added this game to its in-car Arcade:
“Become an astronaut and prove your skills by docking with the International Space Station. Control & guide the rocket in this 3D docking simulator game using a set of controls based on actual interfaces used by NASA astronauts.”
Additional Improvements
-
Enable or disable wireless phone charging pads in Controls > Charging (S3XY) or Controls > Outlets & Mods (Cybertruck)
-
Add Spotify tracks to your queue right from the search screen & scroll through large Spotify playlists, albums, podcasts, audiobooks & your library seamlessly, without paging
-
Take the vibes up another level with rainbow colors during Rave Cave. Accent lights color will change along with the beats of your music. App Launcher > Toybox > Light Sync
-
Lock Sound now includes Light Cycle from Tron Mode. Toybox > Boombox > Lock Sound
What’s Missing
There are a handful of features we expected to see with the Holiday Update, but were not included.
Banish Feature
Tesla has been teasing the Banish functionality for quite a few years, but evidently, it is not quite there yet.
Banish will allow owners to get out of their vehicle at the entrance of their destination, and the car will go find a spot and park itself. Some refer to it as “Reverse Summon.”
Apple CarPlay
With all of the rumors regarding Apple CarPlay and then the evidence that Tesla was working to bring CarPlay to vehicles, we really expected it to come with the Holiday Update.
We’re not upset it’s not here, though. Tesla’s in-car UI is significantly better, at least in our opinion.
Parking Spot Selection
One of the biggest gripes about the new Arrival Features with Full Self-Driving v14 is that choosing a set parking spot is not available. This is especially frustrating for Tesla owners who rent or live in townhouse neighborhoods or apartment complexes with assigned parking.
Tesla seems to be working on this based on the release notes for v14.2, where it said future capabilities would include Parking Spot Selection.
