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.

X clarifies xAI prediction market rumors, hints at future plans
Musk’s AI firm denied rumors of a Kalshi deal but left the door open. Prediction markets + AI could change how we forecast everything.

X dismissed rumors of xAI entering prediction market partnerships. In a recent X post, Elon Musk’s company clarified that xAI had not yet entered formal partnerships in the prediction market.
However, xAI clarification hinted at future exploration in the prediction market, aligning with X’s goal to become an “everything app.” The speculation underscores AI’s potential to reshape predictive analytics.
“Recent speculation about xAI’s involvement in the prediction market space has been circulating. While we’re enthusiastic about the potential of this industry and engaged in various discussions, no formal partnerships have been confirmed to date. Stay tuned!” noted the X team.
X’s statement followed a Tuesday post by Kalshi, hinting at a collaboration with xAI, which was deleted hours later. Kalshi suggested that xAI could leverage AI to analyze X’s news and social media data, enhancing betting decisions on political and economic events.
Bloomberg reported Kalshi aims to use xAI for tailored insights, enabling users to wager on outcomes like Federal Reserve rate changes or elections through derivative contracts.
“There’s deep alignment between prediction markets, social media, and AI. Prediction markets capture what people know — AI scales what people can know,” said Kalshi CEO Tarek Mansour. “This is just the beginning of a long collaboration to unlock the full potential of prediction markets.”
The prediction market industry fits X’s vision to evolve into a comprehensive platform, capitalizing on its trend and news leader role. While xAI’s denial quashes immediate partnership claims, its openness to discussions signals potential interest in prediction markets, where AI could amplify real-time insights.
xAI’s cautious stance reflects its focus on strategic AI development while navigating speculative buzz. As X pursues its “everything app” ambition, prediction markets could enhance its ecosystem, blending social media’s pulse with AI-driven analytics. With no partnerships confirmed, xAI’s future moves may yet redefine how users engage with event-based predictions, positioning it at the forefront of AI innovation.

Elon Musk sends stern warning to Tesla vandals, doubters
Elon Musk sent another warning to vandals that have attacked Tesla for political reasons.

Elon Musk has sent a stern warning to Tesla vandals, doubters, and attackers, who have subjected the company and its owners to political violence through arson and other modes of retaliation.
Over the past few months, Tesla showrooms and vehicles have been hit with numerous attacks from those who have opposed Musk and his political involvement with the Trump Administration. Although Musk has stepped back from his role within government significantly since the start of May, the company is still looked at as a political target.
While the White House has put a clear-cut line on the acts, calling them domestic terrorism and holding those responsible for the damage they have done, there are still numerous and daily instances of keying cars or worse.
Yesterday, Musk continued to send stern warnings to those who oppose Tesla and choose to handle their distaste for the company with violence and vandalism. In a Bloomberg interview at the Qatar Economic Forum, Musk was asked if he took what has happened to Tesla “over the past few months personally.”
Musk replied simply but sternly: “Yes.”

He went on to say that not only will those who vandalized the company and its products owned by consumers be held to the fullest extent of the law, but also those who fund it.
Musk also said during a CNBC interview yesterday that very few people buy a company’s products because of the CEO’s political beliefs, and many people do not even know where those CEOs stand on various social issues.
Although Musk has gone out of his way to be transparent about his beliefs, he has a valid point. He obviously felt that, because of his influence, he held a duty to uphold American values and protect what he felt was an attack on free speech and human rights.
Disagreeing with Musk and his political stances is totally reasonable, but damaging products that consumers bought from his companies is not impacting him directly. Instead, it is making consumers’ lives more difficult.

Tesla Model 3 gets perfect 5-star Euro NCAP safety rating
Tesla prides itself on producing some of the safest vehicles on the road today.

Tesla prides itself on producing some of the safest vehicles on the road today. Based on recent findings from the Euro NCAP, the 2025 Model 3 sedan continues this tradition, with the vehicle earning a 5-star overall safety rating from the agency.
Standout Safety Features
As could be seen on the Euro NCAP’s official website, the 2025 Model 3 achieved an overall score of 90% for Adult Occupants, 93% for Child Occupants, 89% for Vulnerable Road Users, and 87% for Safety Assist. This rating, as per the Euro NCAP, applies to the Model 3 Rear Wheel Drive, Long Range Rear Wheel Drive, Long Range All Wheel Drive, and Performance All Wheel Drive.
The Euro NCAP highlighted a number of the Model 3’s safety features, such as its Active Hood, which automatically lifts during collisions to mitigate injury risks to vulnerable road users, and Automatic Emergency Braking System, which now detects motorcycles through an upgraded algorithm. The Euro NCAP also mentioned the Model 3’s feature that prevents initial door opening if someone is approaching the vehicle’s blind spot.
Standout Safety Features
In a post on its official Tesla Europe & Middle East account, Tesla noted that the company is also introducing new features that make the Model 3 even safer than it is today. These include functions like head-on collision avoidance and crossing traffic AEB, as well as Child Left Alone Detection, among other safety features.
“We also introduced new features to improve Safety Assist functionality even further – like head-on collision avoidance & crossing traffic AEB – to detect & respond to potential hazards faster, helping avoid accidents in the first place.
“Lastly, we released Child Left Alone Detection – if an unattended child is detected, the vehicle will turn on HVAC & alert caregivers via phone app & the vehicle itself (flashing lights/audible alert). Because we’re using novel in-cabin radar sensing, your Tesla is able to distinguish between adult vs child – reduced annoyance to adults, yet critical safety feature for kids,” Tesla wrote in its post on X.
Below is the Euro NCAP’s safety report on the 2025 Tesla Model 3 sedan.
