SpaceX’s Starship rocket sails through first “flight-like” fueling test

Published

SpaceX’s fully-assembled Starship rocket appears to have sailed through a major wet dress rehearsal test on the first attempt.

With the completion of that test, the next-generation SpaceX rocket has taken a big step toward its first orbital launch attempt. Starship measures around 120 meters (~394 ft) tall and 9 meters (~30 ft) wide, making it the largest rocket ever assembled. It’s designed to launch more than 100 metric tons (~220,000 lb) to low Earth orbit (LEO) in a fully-reusable configuration. At liftoff, Starship’s 33 Raptor engines will produce up to 7590 tons (16.7M lbf) of thrust, making it more powerful than any rocket in history by a large margin.

And on Monday, January 23rd, Starship likely became the heaviest rocket ever after SpaceX fully loaded the vehicle with propellant. Surprising most viewers, SpaceX also appeared to complete the complex test associated with that milestone without running into any major issues.

The apparent success is surprising because it simply hasn’t been SpaceX’s approach of choice while developing Starship. Since SpaceX began assembling Starhopper in an empty Texas field in 2018, the Starship program has been almost exclusively managed to prioritize speed and expect failures. The company almost always preferred to build, test, and learn from minimum-viable-product prototypes as quickly as possible, even if that meant that failures were guaranteed.

Because SpaceX expected failures, it learned from them and always had another prototype ready to carry the torch forward. Starship prototypes rarely completed ground or flight tests on the first try, as SpaceX was simultaneously learning – often catastrophically – how to test and operate those vehicles. The culmination of that failure-as-an-option strategy was a series of seven suborbital Starship tests – two short hops of identical prototypes and five launch and landing attempts of five more advanced prototypes between August 2020 and May 2021. On the fifth attempt, after four failures, a full-scale Starship successfully launched to 12.5 kilometers (~41,000 ft), shut off its engines, fell back to Earth, reignited its engines, flipped around, and landed in one piece.

By all appearances, the campaign was the ultimate corroboration of SpaceX’s development strategy. In the second half of 2022, however, SpaceX decided to dramatically change the Starship program’s approach to risk management and systems engineering. Starship testing has become exceptionally cautious over the last several months, as a result.

From fail-fast to slow-and-steady

There is a small chance SpaceX simply got lucky, but Starship’s first fully-assembled wet dress rehearsal test appears to indicate that that caution has paid off. Combined, both stages of the rocket – Ship 24 and Booster 7 – collectively completed dozens of separate proof tests and static fires since mid-2022. They also made it through several far more limited tests while stacked.

Having cautiously characterized each prototype about as well as it possibly could, SpaceX finally pulled the trigger on January 23rd. After hours of conditioning the Starbase, Texas orbital launch site’s giant tank farm, SpaceX opened the floodgates and loaded Ship 24 and Booster 7 with up to 4860 tons (~10.7M lbs) of cryogenic liquid oxygen and liquid methane propellant in about 90 minutes. Once fully loaded, the combined weight of the rocket and propellant likely exceeded 5000 tons (~11M lbs), making Starship the heaviest rocket in history. The next heaviest rockets ever built, Saturn V and N-1, weighed around 2800 tons (~6.2M lbs) fully loaded.

SpaceX was also able to drain Starship and return its propellant to the pad’s ground storage tanks about four hours after filling the rocket.

“Flight-like” testing

The company later confirmed that the test was a “full flight-like wet dress rehearsal,” as suspected, and noted that data gathered from it would “help verify a full launch countdown sequence, as well as the performance of Starship and the orbital pad for flight-like operations.” Parts of the test visible from unaffiliated webcasts like NASASpaceflight’s seemed to confirm as much. Shortly after Starship was fully loaded, for example, SpaceX activated the orbital launch mount’s fire extinguisher system, seemingly practicing the moments before the rocket would otherwise ignite its engines and take flight.

At no point during the wet dress rehearsal did SpaceX appear to enter any kind of hold or abort, indicating that the rocket’s systems were all working well enough together to smoothly complete it on the first try. The only mildly concerning behavior visible during the multi-hour test came shortly after Starship was topped off. Booster 7 opened one of its methane tank gas vents to relieve pressure and instead appeared to vent liquid methane, producing a flammable cloud thousands of feet long. More likely than not, the Super Heavy was slightly overfilled, and the liquid vent was an intentional response to that error. The cloud of methane thankfully did not find an ignition source, and Starship went on to finish the test as planned.

Booster 7’s accidental liquid methane vent was without a doubt the largest vent in Starbase history.

SpaceX has a lot of work left to prepare Ship 24 and Booster 7 for Starship’s first orbital launch attempt. Booster 7 must still complete one or several more static fires, during which it could become the most powerful rocket ever tested. To reduce risk, SpaceX will likely remove Ship 24 while testing Super Heavy, and reassemble the rocket only if Booster 7 passes its tests. SpaceX also needs to repair the pad after static fire testing and work with the Federal Aviation Administration (FAA) to finalize Starship’s first orbital launch license.

But after many false positives, Starship’s successful completion of a wet dress rehearsal on the first try has confirmed that the rocket’s orbital launch debut is – for the first time – actually close at hand.

Tesla gets price target boost, but it’s not all sunshine and rainbows

Published

on

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 2025 Holiday Update: Here’s what it includes, and what it’s missing

Published

on

Credit: Grok

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.

Tesla reportedly testing Apple CarPlay integration: report

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.
