A full-scale Starship rocket has passed a critical test for the first time ever, strongly suggesting that the next-generation launch vehicle could be much closer to orbital readiness than most would imagine.

To be clear, a huge amount of work remains before Starship can be deemed anywhere close to its first orbital flight tests, not the least of which is the fabrication and assembly of the first massive Super Heavy booster(s). However, after Starship SN4’s latest successful May 9th test, it’s hard to see any apparent showstoppers that can’t be handled with a combination of fairly routine testing and iterative progress, as well as time and money. There is certainly room for improvement throughout the program but SpaceX has effectively demonstrated that the biggest practical concerns about its approach to Starship are moot.

Captured live on May 9th and 10th by local resident and photographer Mary (bocachicagal) with the help of NASASpaceflight.com, SpaceX worked for about two days to reconfigure its fourth full-scale Starship prototype after two successful Raptor engine static fires and prepare it for a different kind of test. That work mainly involved removing said Raptor and replacing it with a hydraulic ram stand used to simulate the thrust of 1-3 engines without actually needing to perform a static fire test, further allowing SpaceX to simulate much longer engine operations than its spartan test pad could survive. Around 9pm CDT on May 9th (02:00 UTC, May 10), Starship SN4’s latest trial began.

Known as a cryogenic pressure and load test, it differed from a prior “cryo proof test” completed on April 26th, in which Starship was fully loaded with liquid nitrogen (more than twice as cold as dry ice), pressurized to a bit less than 5 bar (~70 psi), and stressed with hydraulic rams. About a week later, after installing a Raptor engine on a full-scale Starship prototype for the first time ever, Starship SN4 fired up said engine on May 5th – another historic first for the next-generation launch vehicle. 30 hours later, SpaceX performed another wet dress rehearsal (WDR) with liquid methane and oxygen and fired up Starship’s Raptor engine again.

After about 48 hours of reconfiguration, SpaceX moved on to a much more serious cryogenic test. As noted by CEO Elon Musk, the 4.9 bar the rocket previously reached was accepted as enough to perform a Raptor static fire test and possibly enough for a low-stress, low-altitude flight test to ~150m (500 ft). For orbital flight, however, Starship needs to withstand a minimum of 6 bar (~90 psi), while 8.5 bar (125 psi) is preferable to give the rocket the 1.4x safety factor optimal for human spaceflight.

This time, SpaceX – having successfully gathered data from two static fire tests and several wet dress rehearsals – was ready to risk Starship SN4 and pressurized it all the way to 7.5 bar (~110 psi). While ~12% shy of minimum human spaceflight standards, Starship SN4 successfully reached and maintained 7.5 bar while the ship stressed with hydraulic rams to simulate the thrust of three Raptor engines, all of which it survived fully intact. What 7.5 bar does offer, however, is a 1.25x safety factor – on the higher end of aerospace industry standards for uncrewed orbital spaceflight (i.e. cargo/satellite launches).

If Starship can reliably sustain tank pressures of 7.5 bar, the ship’s structure is effectively ready for orbital flight. (SpaceX)

Ready for orbit?

Technically, this means that – pending much additional testing and verification with different serial prototypes and (likely) higher pressures – Starship’s stainless steel structure is effectively qualified for uncrewed orbital launches. Of course, reality is much more complex. To actually perform and survive orbital flights, SpaceX will first need to build and similarly qualify the first Super Heavy boosters and ensure that those unprecedentedly large rockets can survive and sustain ~20-30 Raptor engines firing simultaneously.

Super Heavy’s Raptor count has been reduce to 31 engines but that quantity will still give it the most of any rocket booster in history. (SpaceX)

Aside from Super Heavy, it’s unknown if SpaceX has begun testing Raptor engines at the durations they will need to burn to booster Starships into orbit (TBD; likely 5-10 minutes of continuous operation). Along those lines, SpaceX also needs to build, test, and qualify Raptor’s vacuum-optimized sibling to complement the sea level version’s smaller, less-efficient nozzle. Still, Musk has already revealed that RaptorVac could be a matter of weeks from its first static fire and rocket engine development – while incredibly challenging – is more of a known quantity for SpaceX.

Perhaps the most important unknown is whether SpaceX’s recent May 2020 WDRs and static fires have used autogenous pressurization, a more efficient method of pressurizing rockets by using hot gas generated by their own engines. It’s extremely likely that SpaceX has been autogenously pressurizing Starship SN4 for its recent tests, but if that weren’t the case, it would be a big source of schedule uncertainty without significant redesign work.

Ultimately, SpaceX appears to have proven that orbital-class rockets can be built cheaply out of commodified steel in extraordinarily spartan production facilities. Many, many challenges remain but the biggest uncertainty and hurdle facing SpaceX’s Starship program and ambitions is well on its way to being fully put to rest.

Elon Musk hits back at former Tesla employee who disagrees with pay package

Tesla is worth more than all other automotive companies combined. Which of those CEOs would you like to run Tesla?

It won’t be me.

Elon Musk gave a tough response to a former Tesla employee who spoke out on X about the structure of the CEO’s pay package, arguing that it is an overpayment and would not generate enough shareholder value.

Without a doubt, the biggest issue on the bill at this year’s Tesla Shareholder Meeting in November is that of the pay package that was proposed to CEO Elon Musk.

As the Shareholder Meeting approaches, Tesla is urging those investors to vote in support of Musk’s pay package. So far, the community has been overwhelmingly supportive of giving Musk his massive payday, which could give him $1 trillion in additional holdings if he completes each of the outlined performance tranches.

However, there are a handful of institutional and individual shareholders who have pushed back against the package, either because of its value or because they feel it does not benefit shareholders enough.

Last week, we reported that Institutional Shareholder Services (ISS) advised voting against Tesla’s pay package for Musk. The firm said the payday would give Musk”extraordinarily high pay opportunities over the next ten years,” and it would “reduce the board’s ability to meaningfully adjust future pay levels.”

Tesla CEO Elon Musk’s $1 trillion pay package hits first adversity from proxy firm

Additionally, it called the value of the pay package “astronomical.”

On Saturday, a former Tesla employee said on X that Tesla’s proposed pay package for Musk would “barely beat inflation and it would underperform the S&P 500 considerably.” Additionally, he said:

“Sorry, Tesla, some of us (and supposedly, ISS too) simply don’t think that underperforming the S&P 500 this much is worth paying somebody 20 billion dollars worth of company value.

As a fan, I love Tesla, I want it to succeed. As a shareholder, I don’t want Tesla to over-pay for its CEO I strongly believe that the 2025 pay package proposal would over-pay for its CEO, and that other competent CEOs could grow Tesla just as much with way less political drama and cost investors much less that this proposal.”

Musk responded bluntly:

“Tesla is worth more than all other automotive companies combined. Which of those CEOs would you like to run Tesla? It won’t be me.”

It seems the worry about Musk’s potential involvement in politics still looms to many, based on the responses to Musk’s post, which frequently mention that as a downside of his last year as Tesla CEO. However, Tesla’s Board confronted that directly.

In its proxy filing after announcing the pay package, Tesla said that it had three commitments, one of which was that the company would “receive assurances that Musk’s involvement with the political sphere would wind down in a timely manner.”

Musk’s previous pay package was approved by shareholders twice, but it never made it to the CEO because of a lawsuit with the Delaware Chancery Court brought forth by a small-time shareholder.

The response from Musk does seem to show that if this time is no different, he will inevitably step down as CEO in the coming years.

Tesla rivals are lagging behind alarmingly in this crucial EV necessity

Tesla rivals are lagging behind the company in alarming fashion in this crucial EV necessity: charging.

Tesla has had a long-standing reputation for having the most expansive electric vehicle charging infrastructure, and even as other companies have launched their own as part of the vehicle manufacturing, nobody seems to keep pace with the EV leader.

A report from Paren exhibited this trend in Q3, showing that Tesla overwhelmingly dominated EV charging stall installations over the past three months. This data is based on U.S. installations, where Tesla has long held a dominating position as the leader in overall electric vehicle sales for many years.

In Q3, Tesla installed 1,820 new chargers in the United States, bringing its total presence to 34,328, an all-time market share of 53.2 percent of all charging stalls in the country.

What’s alarming is the fact that all other networks — ChargePoint, Red E, Electrify America, EV Connect, EVgo, Ionna, Blink, Pilot Flying J, and Rivian Adventure — only installed 841 chargers collectively in Q3. That is nearly 1,000 units behind Tesla, despite there being nine companies contributing as competitors.

These nine networks have 10,055 stalls in total, the data from Paren shows, accounting for 15.6 percent of the chargers in the United States.

EV charging is such a crucial part of the ownership experience, and also a part of the ongoing expansion of EV adoption in the United States.

As more people buy EVs and they become a more prominent form of passenger transportation, more chargers are needed. Many owners charge at home, but charging options in public are important to have for traveling, commuting, and for those who do not have access to residential charging.

Tesla ownership without home charging: Here’s how it’s done

With Tesla opening its Supercharger Network to the majority of EV brands over the past two years, things have gotten better.

It has been alarming to see so many companies involved in EV infrastructure essentially accept the gap between Tesla and themselves; not a single company has tried to up its pace to catch up to what Tesla has.

When it comes down to it, as long as there is charging, the manufacturer does not truly matter.

However, it would be nice to see Tesla have some competition in the space, but with its domination and head start in the infrastructure division, it seems the company will have this competitive advantage for years to come.

Tesla updates fans on its plans for the Roadster

Earlier in 2025, Musk said Tesla would host the “most epic demo” for the Roadster in late 2025. We’re in Q4, so time is running out, but we finally got the update we’ve been waiting for from von Holzhausen on the Ride the Lightning podcast yesterday.

Tesla has finally updated fans on its plans for the Roadster after stating earlier this year it would host the “most epic demo,” showcasing the vehicle’s capabilities.

The Roadster is amongst the most highly anticipated automotive releases in the entire industry, and was set for release in 2020 initially. However, Tesla got so caught up with scaling up the Model Y and focusing on autonomy that the project took a figurative backseat.

Elon Musk teases Tesla’s “most epic demo” by end of year

In the years since its planned release, we have not seen much of the vehicle. Company executives like Elon Musk and Chief Designer Franz von Holzhausen have hinted at things about it and teased us with potential release dates, but each time, it has been delayed.

Last year, Tesla planned to show something, but Musk saw what improvements had been made from the original design unveiled back in 2017 and figured the company could go a step further, only delaying the project another year.

But what’s another year, right?

Earlier in 2025, Musk said Tesla would host the “most epic demo” for the Roadster in late 2025. We’re in Q4, so time is running out, but we finally got the update we’ve been waiting for from von Holzhausen on the Ride the Lightning podcast yesterday.

Confirming the demo was still on for this year, he also teased some new features that the Roadster will have, like new paint options.

Von Holzhausen said:

“I’m excited to showcase the Roadster for a lot of different reasons. The wait will be worth it.”

Additionally, he said the capabilities of the Roadster are truly something, and they have gotten the vehicle to a point that it seems to test the “limits of physics.” Franz added that Tesla has “really gotten to a point where we are going to be achieving that standard that we set out.”

Obviously, the Roadster is not a major contributor to Tesla’s mission or to its future, which mostly leans on artificial intelligence and Robotaxi or autonomy. However, it is still a product that Tesla needs to offer, as many have put massive $250,000 downpayments on the vehicle in an attempt to purchase one.

Tesla has not yet announced a date for its demo of the Roadster, but based on Franz’s interview, it seems the company is still on track to hold that by the end of the year.
