Just a few days after CEO Elon Musk said that SpaceX’s first true Super Heavy prototype was “almost done,” the booster has been stacked to its full height.

Standing more than 65 meters (~215 ft) tall, Super Heavy Booster 3 (B3) assembly is now just a few major welds away from completion after SpaceX teams mated the final two sections of its propellant tanks and structure. Assembled separately out of approximately 12 barrel sections each made up of 2-4 steel rings, Booster 3’s methane tank (13 rings) and oxygen tank (23 rings) were stacked together on June 29th, just over six weeks after the process began.

Earlier the same day, speaking at the 2021 Mobile World Congress, Musk confirmed what was now fairly clear to most observers, stating that SpaceX is “going to do its best” to complete Starship’s first orbital (or, at least, space) launch attempt “in the next few months.” In other words, a several-month-old launch target of no later than July 2021 is most likely out of reach despite a strong effort from SpaceX.

The most significant technical hurdles still in the way involve a few incremental Starship milestones and, more importantly, the qualification of the largest and most powerful rocket booster ever built. Standing almost as tall as an entire two-stage Falcon 9 or Falcon Heavy, Super Heavy is expected to weigh more than 3500 tons (~7.7 million lbs) and produce at least ~5000 tons (~11 million lbf) of thrust at liftoff – more than any other rocket booster in history, liquid or solid.

Borrowing heavily from Starship, Super Heavy is mostly built with the same techniques out of the same steel rings, stringers, and structures, save for a few booster-specific components. However, Super Heavy is also designed to use 29-32 Raptor engines while the most SpaceX has ever simultaneously installed, tested, or flown is three. In other words, while Super Heavy is in many ways simpler than Starship, it will still be treading plenty of new ground when it heads to the launch pad for the first time.

Plenty of final integration tasks remain before Super Heavy B3 will be ready to start qualification testing but SpaceX could feasibly be ready to roll the booster to the launch site within the next week or two. Once installed on a former Starship launch mount that’s been customized for booster testing, Super Heavy will likely be put through its first cryogenic proof and static fire test(s) to verify that the massive rocket is performing as expected. The static fire process could be fairly lengthy if SpaceX decides to incrementally increase the number of Raptor engines installed.

In the likely event that Booster 3 begins testing without engines installed, SpaceX will also have to go through the process of installing up to 29 Raptors while Super Heavy is sitting out in the elements on a launch mount. Based on experience with Starship, installing that many engines in situ could take at least several days – and maybe longer. All told, the fun is only just beginning.

Tesla looks to upgrade Matrix Headlights with new features

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.

Tesla is looking to upgrade its Matrix Headlights, a unique and high-tech feature that is available on several of its vehicles. The headlights aim to maximize visibility for Tesla drivers while being considerate of oncoming traffic.

The Matrix Headlights Tesla offers utilize dimming of individual light pixels to ensure that visibility stays high for those behind the wheel, while also being considerate of other cars by decreasing the brightness in areas where other cars are traveling.

Here’s what they look like in action:

As you can see, the Matrix headlight system intentionally dims the area where oncoming cars would be impacted by high beams. This keeps visibility at a maximum for everyone on the road, including those who could be hit with bright lights in their eyes.

There are still a handful of complaints from owners, however, but Tesla appears to be looking to resolve these with the coming updates in a Software Version that is currently labeled 2026.2.xxx. The coding was spotted by X user BERKANT:

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.

Finally, the new system will prevent the high beams from glaring back at the driver. The system is made to dim when it recognizes oncoming cars, but not necessarily objects that could produce glaring issues back at the driver.

Tesla’s revolutionary Matrix headlights are coming to the U.S.

This upgrade is software-focused, so there will not need to be any physical changes or upgrades made to Tesla vehicles that utilize the Matrix headlights currently.

Elon Musk’s xAI has signed an agreement with the United States Department of Defense (DoD) to allow Grok to be used in classified military systems.

Previously, Anthropic’s Claude had been the only AI system approved for the most sensitive military work, but a dispute over usage safeguards has reportedly prompted the Pentagon to broaden its options, as noted in a report from Axios.

Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations. 

The publication reported that xAI agreed to the Pentagon’s requirement that its technology be usable for “all lawful purposes,” a standard Anthropic has reportedly resisted due to alleged ethical restrictions tied to mass surveillance and autonomous weapons use.

Defense Secretary Pete Hegseth is scheduled to meet with Anthropic CEO Dario Amodei in what sources expect to be a tense meeting, with the publication hinting that the Pentagon could designate Anthropic a “supply chain risk” if the company does not lift its safeguards. 

Axios stated that replacing Claude fully might be technically challenging even if xAI or other alternative AI systems take its place. That being said, other AI systems are already in use by the DoD. 

Grok already operates in the Pentagon’s unclassified systems alongside Google’s Gemini and OpenAI’s ChatGPT. Google is reportedly close to an agreement that will result in Gemini being used for classified use, while OpenAI’s progress toward classified deployment is described as slower but still feasible. 

The publication noted that the Pentagon continues talks with several AI companies as it prepares for potential changes in classified AI sourcing.

Elon Musk denies Starlink’s price cuts are due to Amazon Kuiper

“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X.

Elon Musk has pushed back on claims that Starlink’s recent price reductions are tied to Amazon’s Kuiper project.

In a post on X, Musk responded directly to a report suggesting that Starlink was cutting prices and offering free hardware to partners ahead of a planned IPO and increased competition from Kuiper.

“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X. “The lower the cost, the more Starlink can be used by people who don’t have much money, especially in the developing world.”

The speculation originated from a post summarizing a report from The Information, which ran with the headline “SpaceX’s Starlink Makes Land Grab as Amazon Threat Looms.” The report stated that SpaceX is aggressively cutting prices and giving free hardware to distribution partners, which was interpreted as a reaction to Amazon’s Kuiper’s upcoming rollout and possible IPO.

In a way, Musk’s comments could be quite accurate considering Starlink’s current scale. The constellation currently has more than 9,700 satellites in operation today, making it by far the largest satellite broadband network in operation. It has also managed to grow its user base to 10 million active customers across more than 150 countries worldwide. 

Amazon’s Kuiper, by comparison, has launched approximately 211 satellites to date, as per data from SatelliteMap.Space, some of which were launched by SpaceX’s Falcon 9 rocket. Starlink surpassed that number in early January 2020, during the early buildout of its first-generation network.

Lower pricing also aligns with Starlink’s broader expansion strategy. SpaceX continues to deploy satellites at a rapid pace using Falcon 9, and future launches aboard Starship are expected to significantly accelerate the constellation’s growth. A larger network improves capacity and global coverage, which can support a broader customer base.

In that context, price reductions can be viewed as a way to match expanding supply with growing demand. Musk’s companies have historically used aggressive pricing strategies to drive adoption at scale, particularly when vertical integration allows costs to decline over time.
