SpaceX rolls largest rocket booster ever built to the launch pad
Six weeks after assembly began, SpaceX has completed Starship’s first true Super Heavy booster prototype, rolled it out of its ‘high bay’ nest, and installed the building-sized rocket at the launch pad.
Standing some 65 meters (~215 ft) tall, Super Heavy Booster 3 (B3) is the same height as an entire two-stage Falcon rocket and Dragon spacecraft and is expected to singlehandedly weigh six times more than a fully-fueled Falcon 9 when loaded with liquid oxygen and methane propellant. Once Super Heavies are eventually outfitted with a full 32 Raptors, more engines than any other rocket in history, the booster will also produce more than twice the thrust of NASA’s Saturn V Moon rocket – still the most powerful vehicle ever successfully flown.
Assembled out of 36 steel rings, three tank domes, and dozens of other major components, Super Heavy B3 borrows heavily from the Starship production apparatus SpaceX has built and refined over the last ~18 months. Boosters use the same welding and integration jigs, facilities, and strategies and are built out of the same steel rings, stringers, stiffeners, and dome ‘gores.’
In some ways, Super Heavy boosters are actually a good deal simpler than Starships, which require a custom nose cone, secondary ‘header’ tanks, extra plumbing, actuating flaps, a heat shield with thousands of tiles, and more. Boosters, by comparison, require no heat shield and only need two main tanks made out of identical steel rings. However, all three Super Heavy domes (forward, common, and thrust) are mostly custom or require major modifications on top of parts shared with Starship domes.
Speaking on June 30th, Elon Musk revealed that Booster 3 was “very hard to build” and would be exclusively used for ground tests, reiterating that Super Heavy B4 is currently the first booster scheduled to fly. Curiously, the SpaceX CEO also said that “much of [Super Heavy’s] design” would be changed between Booster 3 and Booster 4, raising questions about what the company hopes to gain from Booster 3 “ground tests.”
Regardless, those tests are now on track to begin as early as Monday, July 6th after SpaceX transported Super Heavy Booster 3 from the factory to the launch pad and rapidly installed the rocket on a test platform on July 1st. Following in the footsteps of Starship, Super Heavy’s first hurdle will likely be an ambient proof test, in which nitrogen gas is used to check for leaks and verify general structural integrity under pressure.
Once complete, Booster 3 will be put through a cryogenic proof test, effectively replacing gaseous nitrogen with its supercooled liquid equivalent to simulate the immense thermal and mechanical stress incurred by similarly cold liquid oxygen and methane propellant. How exactly that test will be done is unclear given that Super Heavy can feasibly hold more than 3100 tons of liquid nitrogen and nowhere near that much storage capacity has been installed. The most important goal of cryo proof testing is to demonstrate that Super Heavy is structurally sound with its tanks pressurized to nominal flight pressures – likely at least 7-8 bar (~100-120 psi).
If successful, there are two possible routes SpaceX could go: more cryogenic proof testing at higher (and thus potentially destructive) pressures or static fire testing with one or several Raptor engines installed. Given Musk’s statement that the first flightworthy Super Heavy booster would implement major design changes, it’s unclear if Booster 3 is of a high enough fidelity to warrant static fire testing or if SpaceX has effectively turned the Super Heavy prototype into a massive ‘test tank’ instead.

Tesla takes first step in sunsetting Model S and X with drastic move
Tesla won’t be taking custom orders of the Model S or Model X in Europe any longer.

Tesla has seemingly taken the first step in sunsetting two of its older vehicles, the Model S and Model X, by ending international orders.
The flagship sedan and SUV from Tesla are the two oldest cars in the company’s lineup. They account for a very small portion of overall sales, and several years ago, CEO Elon Musk admitted that Tesla only continues to build and sell them due to “sentimental reasons.”
Earlier this year, there were calls for Tesla to end the production of the two cars, but Lars Moravy said that the Model S and Model X were due to get some love later in 2025. That happened, but the changes were extremely minor.
Tesla launches new Model S and Model X, and the changes are slim
Some took this as an indication that Tesla has kind of moved on from the Model S and Model X. A handful of people seemed to think Tesla would overhaul the vehicles substantially, but the changes were extremely minor and included only a few real adjustments.
In Europe, customers are unable to even put a new order in on a Model S or Model X.
We noticed earlier today that Tesla pressing the ‘Order’ button on either of the flagship vehicles takes you to local inventory, and not the Design Studio where you’d configure your custom build:

Tesla simply does not make enough Model S or Model X units to justify the expensive logistics process of shipping custom orders overseas. It almost seems as if they’re that they will essentially build a bunch of random configurations, send them overseas every few months, and let them sell before replenishing inventory.
Inversely, it could also mean Tesla is truly gearing up to sunset the vehicle altogether. It seems unlikely that the company will fade them out altogether in the next couple of years, but it could absolutely think about ending international orders because volume is so low.

Tesla inks multi-billion-dollar deal with LG Energy Solution to avoid tariff pressure
Tesla has reportedly secured a sizable partnership with LGES for LFP cells, and there’s an extra positive out of it.

Tesla has reportedly inked a multi-billion-dollar deal with LG Energy Solution in an effort to avoid tariff pressure and domesticate more of its supply chain.
Reuters is reporting that Tesla and LGES, a South Korean battery supplier of the automaker, signed a $4.3 billion deal for energy storage system batteries. The cells are going to be manufactured by LGES at its U.S. factory located in Michigan, the report indicates. The batteries will be the lithium iron phosphate, or LFP, chemistry.
Tesla delivers 384,000 vehicles in Q2 2025, deploys 9.6 GWh in energy storage
It is a move Tesla is making to avoid buying cells and parts from overseas as the Trump White House continues to use tariffs to prioritize domestic manufacturing.
LGES announced earlier today that it had signed a $4.3 billion contract to supply LFP cells over three years to a company, but it did not identify the customer, nor did the company state whether the batteries would be used in automotive or energy storage applications.
The deal is advantageous for both companies. Tesla is going to alleviate its reliance on battery cells that are built out of the country, so it’s going to be able to take some financial pressure off itself.
For LGES, the company has reported that it has experienced slowed demand for its cells in terms of automotive applications. It planned to offset this demand lag with more projects involving the cells in energy storage projects. This has been helped by the need for these systems at data centers used for AI.
During the Q1 Earnings Call, Tesla CFO Vaibhav Taneja confirmed that the company’s energy division had been impacted by the need to source cells from China-based suppliers. He went on to say that the company would work on “securing additional supply chain from non-China-based suppliers.”
It seems as if Tesla has managed to secure some of this needed domestic supply chain.

Tesla brings perhaps the coolest interior feature to cars in latest update
Tesla adds on to the “fun” aspect of its vehicles.

Tesla has brought perhaps the coolest interior feature to its cars in a new update that is rolling out to vehicles now.
The feature will require a newer vehicle that has interior ambient lighting, which is present on the new Model S, Model X, Model 3 “Highland,” and Model Y “Juniper.” The Cybertruck also has ambient lighting strips throughout.
Tesla Model Y’s ambient lighting design changes revealed in leaked video
With the Version 2025.26+ Software Update, Tesla is rolling out a new “Sync Accent Lights w/ Music” feature, which is available on the Tesla Toybox:
Turn your Tesla into a rave cave with the new Light Sync feature 🎶
Rolling out now in software update 2025.26+ pic.twitter.com/IIsQxZ9jDP
— Tesla (@Tesla) July 29, 2025
To enable the feature, you’ll access the Toybox, choose “Light Sync,” and then choose “Sync Accent Lights w/ Music.”
Although it does not improve the performance of the vehicle, it is yet another example of Tesla making one of the coolest cars out there. This is truly a cool add-on that can be used to impress your friends and family.
