SpaceX fires up Starship and Super Heavy booster hours apart

SpaceX appears to have successfully fired up a Starship and Super Heavy booster hours apart, testing a total of three new Raptor 2 engines on the two rockets.

SpaceX says it completed a two-engine static fire with Starship 24 less than three hours after the company successfully ignited a Raptor 2 engine installed on a rocket prototype for the first time. That earlier test, performed by Super Heavy Booster 7, was also the first time SpaceX used its new Starbase orbital launch site to support a static fire test and the second-ever static fire of a Starship booster prototype. Had the company called it quits after Booster 7 survived its first intentional trial by fire, it would have still been an exceptionally successful day.

But SpaceX wasn’t done.

Instead, after Booster 7’s seemingly flawless single-Raptor static fire at 5:25 pm CDT, SpaceX loaded Starship 24 with a small amount of liquid oxygen and methane propellant and ignited two of the ship’s six engines around 8:18 pm. It was not initially clear how many engines were involved but a tweet from SpaceX later confirmed it was two. More likely than not, one of those engines was a sea level-optimized Raptor with a smaller bell nozzle and the other was a vacuum-optimized Raptor with a much larger nozzle.

Almost ten months ago, Starship 20 – SpaceX’s first potentially orbital-class Starship prototype – began static fire testing in a somewhat similar way. Its first day of static fires began with a single Raptor Vacuum engine and ended with a simultaneous RVac and sea-level Raptor test in October 2021. In some ways, SpaceX has been a bit less cautious with Starship 24, which is the second potentially orbital-class prototype to begin proof testing. Ship 24 already has all six Raptors installed, whereas Ship 20 only had four of six engines installed during its first static fire tests. SpaceX also took about three weeks to progress from Ship 20’s first static fire test to its first static fire of all six engines, whereas it appears that Ship 24 could potentially attempt its first six-engine test just a few days to a week later.

On the other hand, Ship 24’s path to its first static fire was substantially longer than Ship 20’s. Ship 20 completed its first static fire test(s) just 25 days after its first proof test, referring to the process of verifying that the prototype was in good working order before moving on to riskier testing with flammable propellant and intentional ignitions. Ship 20 also completed its first six-engine static fire 46 days after testing began. Ship 24, meanwhile, took 75 days to go from its first proof test to its first static fire – almost three times slower than Ship 20, a prototype that was essentially the first of its kind.

It’s possible that Ship 24’s upgraded Raptor 2 engines are partially or fully to blame. Instead of jumping straight into ‘hot’ Raptor testing like Ship 20, which began that particular campaign with a partial-ignition preburner test, SpaceX put Ship 24 through seven ‘spin-prime’ tests before its first static fire. For Raptor, spin-primes test the ignition step before preburner ignition, which is itself a step before main combustion chamber ignition (where the engine starts to produce meaningful thrust). Raptor startup procedures likely involve flowing high-pressure gaseous helium, nitrogen, or propellant (oxygen/methane) through the engine to spin up its turbopumps, ‘priming’ them for preburner and main combustion chamber ignition.

On Raptor 1, the preburners would ignite once a high enough flow rate was achieved, producing hot gas that the main combustion chamber would mix and ignite one last time to start the engine. In a recent interview with Tim Dodd (“The Everyday Astronaut”), CEO Elon Musk revealed that SpaceX was able to “remove torch igniters” from Raptor 2’s main combustion chamber (MCC). It’s unclear if that means that Raptor 2 now has zero MCC igniters, but a major change in the overall ignition process could explain why the start of Ship 24 and Booster 7 engine testing was so sluggish. So could the unintended explosion Booster 7 caused when SpaceX attempted to spin-prime all 33 of its Raptor 2 engines at once.

Regardless, SpaceX has finally crossed that particular Rubicon and, with any luck, Raptor 2 testing will begin to speed up on both Starship 24 and Super Heavy Booster 7. SpaceX has test windows scheduled on August 11th, 15th, and 16th. A warning distributed to Boca Chica, Texas residents on August 10th confirmed that the company intends to perform at least one more static fire test on the 11th.

Norway’s $2 trillion sovereign wealth fund votes against Elon Musk’s 2025 performance award

The fund is managed by Norges Bank Investment Management (NBIM), and it holds a 1.14% stake in Tesla valued at about $11.6 billion.

Norway’s $2 trillion sovereign wealth fund has voted against Elon Musk’s 2025 performance award, which will be ultimately decided at Tesla’s upcoming annual shareholder meeting. 

The fund is managed by Norges Bank Investment Management (NBIM), and it holds a 1.14% stake in Tesla valued at about $11.6 billion.

NBIM’s opposition

NBIM confirmed it had already cast its vote against Musk’s pay package, citing concerns over its total size, dilution, and lack of mitigation of key person risk, as noted in a CNBC report. The fund acknowledged Musk’s leadership of the EV maker, and it stated that it will continue to seek dialogue with Tesla about its concerns. 

“While we appreciate the significant value created under Mr. Musk’s visionary role, we are concerned about the total size of the award, dilution, and lack of mitigation of key person risk- consistent with our views on executive compensation. We will continue to seek constructive dialogue with Tesla on this and other topics,” NBIM noted.

The upcoming Tesla annual shareholder meeting will decide whether Musk should receive his proposed 2025 performance award, which would grant him large stock options over the next decade if Tesla hits several ambitious milestones, such as a market cap of $8.5 trillion. The 2025 performance award will also increase Musk’s stake in Tesla to 25%.

Elon Musk and NBIM

Elon Musk’s proposed 2025 CEO performance award has proven polarizing, with large investors split on whether the executive should be given a pay package that, if fully completed, would make him a trillionaire. 

Institutional Shareholder Services and Glass Lewis have recommended that shareholders vote against the deal, and initiatives such as the “Take Back Tesla” campaign have rallied investors to oppose the proposed performance award. On the other hand, other large investors such as ARK Invest and the State Board of Administration of Florida (SBA) have urged shareholders to approve the compensation plan. 

Interestingly enough, this is not the first time that Musk and NBIM have found themselves on opposing sides. Last year, NBIM voted against reinstating Musk’s 2018 performance award, which had already been fully accomplished but was rescinded by a Delaware judge.

Later reports shared text messages between Musk and NBIM Chief Executive Nicolai Tangen, who was inviting the CEO to a dinner in Oslo. Musk declined the invitation, writing, “When I ask you for a favor, which I very rarely do, and you decline, then you should not ask me for one until you’ve done something to make amends. Friends are as friends do.”

Tesla begins production of new Model Y trim at Giga Berlin

Tesla announced on Monday that its Model Y Standard configuration was officially being built at Giga Berlin, less than one month after the company officially announced the configuration early last month.

Tesla has begun production of the new Model Y trim at Gigafactory Berlin, the company’s production plant in Germany.

Tesla announced on Monday that its Model Y Standard configuration was officially being built at Giga Berlin, less than one month after the company officially announced the configuration early last month.

On October 7, Tesla announced the launch of the Model 3 and Model Y Standard trim levels, its answer to the call for affordable EVs within its lineup and its response to the loss of the $7,500 electric vehicle tax credit.

On October 3, Tesla started production of the vehicles in Germany:

The Standard iteration of the Model Y is void of many of the more premium features that are available in the Rear-Wheel-Drive, All-Wheel-Drive, and Performance trims of the vehicle are equipped with.

A few of the features of the Model Y Standard are:

  • Single Motor configuration
  • No rear touchscreen
  • Textile seats with vegan leather, instead of all vegan leather
  • 320-mile range
  • No glass roof

The launch of the Model Y Standard was truly a move to help Tesla get vehicles into the sub-$40,000 price point, and although many consumers were hoping to see the company get closer to $30,000 with these cars, this is a great starting point.

Deliveries in the United States have already started, and it seems it will be a vehicle that will do one of two things: either push some consumers to finally make the jump to Tesla, or it will give car buyers another reason to buy the Premium trims, as they may feel the lack of features is not a good enough deal.

This is something we saw with the Cybertruck’s Rear-Wheel-Drive configuration, which launched last year and ended up being more of the latter option listed above.

The Tesla Model Y Standard is actually a great deal in Europe

It was only a $10,000 discount from the All-Wheel-Drive Cybertruck, but it also did not have adaptive air suspension, premium interiors, or the powered tonneau cover, which many people felt was too much of a sacrifice.

The Rear-Wheel-Drive Cybertruck was discontinued only a few months later.

It does not seem as if this is the case with the Model Y Standard, which already seems to be an attractive option to some buyers.

Tesla has officially begun the wide rollout of Full Self-Driving (Supervised) v14 to the Cybertruck about a month after the company started rolling it out to other vehicles in the fleet.

On Monday, Tesla officially started rolling out v14.1.5 to Cybertruck owners, the first FSD v14 rollout for owners of the all-electric pickup.

Owners have been anxiously waiting for Tesla to begin the wide release of v14 to Cybertruck, as the company said it would refine the suite for the vehicle.

Tesla has finally started rolling out to many owners, who are reporting that their Cybertrucks are downloading Software Update 2025.38.8.5, which contains FSD v14.1.5:

Tesla has to be more cautious with rolling out FSD on the Cybertruck than on other vehicles for a few reasons. Initially, the Cybertruck utilizes an all-wheel steering system that turns differently than the S3XY lineup. This creates a challenge for the Tesla AI team as they have to cater to this specific maneuvering change.

Additionally, the Cybertruck is much larger, and the exterior cameras responsible for seeing the vehicle’s surroundings are placed differently than those of the other vehicles.

This requires additional calibration to ensure safety.

The full release notes for Full Self-Driving v14.1.5 are as follows:

  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, in a Parking Garage, or at the Curbside.
  • Added handling to pull over or yield for emergency vehicles (e.g. police cars, fire trucks, ambulances).
  • Added navigation and routing into the vision-based neural network for real-time handling of blocked roads and detours.
  • Added additional Speed Profile to further customize driving style preference.
  • Improved handling for static and dynamic gates.
  • Improved offsetting for road debris (e.g. tires, tree branches, boxes).
  • Improve handling of several scenarios including: unprotected turns, lane changes, vehicle cut-ins, and school buses.
  • Improved FSD’s ability to manage system faults and recover smoothly from degraded operation for enhanced reliability.
  • Added alerting for residue build-up on interior windshield that may impact front camera visibility. If affected, visit Service for cleaning!
