SpaceX tweaks Starship's Super Heavy rocket booster as design continues to evolve
CEO Elon Musk says that SpaceX continues to evolve the design of its next-generation Starship spacecraft and Super Heavy rocket booster, a process of continuous improvement the company has successfully used for a decade.
Designed to place more than 100 metric tons (220,000 lb) of payload into Low Earth Orbit (LEO), Starship would effectively double (and possibly triple) the expendable performance of SpaceX’s existing Falcon Heavy rocket. Critically, it would be able to dramatically outclass Falcon Heavy (and Falcon 9 even more so) in a fully reusable configuration, meaning that both the Starship upper stage and Super Heavy booster could be recovered and reused.
Since SpaceX first publicly revealed its next-generation launch vehicle and Mars ambitions in September 2016, the path to realizing the dream of a fully-reusable super heavy-lift launch vehicle has been decidedly windy. After making the radical decision to move entirely from carbon composites to stainless steel in late 2018, the Starship design has remained relatively similar, coalescing around a specific concept that has matured to full-scale tank tests. Now, Musk says that Super Heavy’s design was tweaked slightly to make the booster even taller than before, while he later noted that Starship’s design also continues to “[evolve] rapidly.”
According to Musk, the Super Heavy booster will be stretched by a steel ring or two, reaching a new height of ~70m (230 ft). In other words, Starship’s first stage alone will measure as tall as the entirety of a Falcon 9 or Falcon Heavy rocket – first stage, second stage, and payload fairing included. Powered by up to 37 Raptor engines, a Super Heavy booster could produce more than ~90,000 kN (19,600,000 lbf) of thrust at liftoff – an incredible 12 times as much thrust as SpaceX’s workhorse Falcon 9 rocket.
Starship, meanwhile, will be a beast of an orbital-class upper stage on its own, measuring at least 50m (165 ft) tall and weighing some 1350 metric tons (3 million lb) fully-fueled. Stacked on top of Super Heavy, a Starship ‘stack’ would reach a staggering 120m (395 ft) and weigh more than 5000 metric tons (11 million lb) once loaded with liquid oxygen and methane propellant.
In simple terms, Starship/Super Heavy should be the tallest, heaviest, and most powerful launch vehicle ever assembled once it heads to the launch pad for the first time. While SpaceX is making great daily progress its ever-growing South Texas rocket factory, built up from next to nothing in a matter of months, it could still be quite some time before that milestone is within reach.
SpaceX’s process of continuously tweaking and improving the design and production of its rockets does typically have that effect. However, it’s more a symptom of the company’s approach to hardware and software development. Instead of working slowly and carefully from nothing to a preconceived finished product, SpaceX typically seeks to design, build, and test the minimum viable product, gradually improving (or entirely replacing) past ideas, designs, and hardware until overarching goals are fully achieved.
With Falcon 9 and Falcon Heavy, this meant beginning with Falcon 1, a dead-simple proof-of-concept rocket. After successfully reaching orbit, SpaceX expanded its Falcon 9 development program, itself focused initially on the minimum viable product – a full-scale expendable rocket. Since Elon Musk founded SpaceX in 2002, the goal has always been to build a fully-reusable rocket – the company has simply chosen the far more sustainable and practical approach of tackling only a select few problems at a time.
The Starship and Falcon development programs aren’t directly comparable but it’s safe to say that Starship is currently still in the very early stages of hardware development. Shortly after revealing Super Heavy’s height growth, Musk noted that Starship’s design is also being tweaked.
Sketching out a rough series of upgrades that could feasibly be made to the reusable spacecraft’s currently design, Musk thinks that Starship’s conical tank domes (and thus Super Heavy’s, too) could be flattened. That might allow an extra ~3m (10 ft) of propellant tank space to be squeezed into the same 50m Starship length, improving performance by simply using the vehicle’s fixed volume more efficiently.
With a nascent factory quite literally churning out Starship hardware, these tweaks are a whole different animal. Thanks to data and insight gathered from testing actual full-scale Starship tanks, up to and including fully-assembled tank sections, SpaceX will be able to guide its continuous improvement with even greater precision, honing in on the next-generation rocket’s orbital launch debut.

Tesla board reveals reasoning for CEO Elon Musk’s new $1 trillion pay package
“Yes, you read that correctly: in 2018, Elon had to grow Tesla by billions; in 2025, he has to grow Tesla by trillions — to be exact, he must create nearly $7.5 trillion in value for shareholders for him to receive the full award.”
Tesla’s Board of Directors has proposed a new pay package for company CEO Elon Musk that would result in $1 trillion in stock offerings if he is able to meet several lofty performance targets.
Musk, who has not been meaningfully compensated since 2017, completed his last pay package by delivering billions in shareholder value through a variety of performance-based “tranches,” which were met and resulted in the award of billions in stock.
Elon Musk’s new pay plan ties trillionaire status to Tesla’s $8.5 trillion valuation
However, Musk was unable to claim this award due to a ruling by the Delaware Chancery Court, which deemed the payout an “unfathomable sum.”
Now, the company is taking steps to ensure Musk gets paid, as the Board feels that it is crucial to retain its CEO, who has been responsible for much of the company’s success.
This is not a statement to undermine the work of all of Tesla’s terrific employees, but a ship needs to be captained by someone, and Musk has proven he is the right person for the job.
The Board also believes that, based on a statement made by the company in its proxy, various issues will be discussed during the upcoming Shareholder Meeting.
Robyn Denholm and Kathleen Wilson-Thompson recognized Musk’s contributions in a statement, which encouraged shareholders to vote to approve the payout:
“We’re asking you to approve the 2025 CEO Performance Award. In designing the new performance award, we explored numerous alternatives. Ultimately, the new award aims to build upon the success of the 2018 CEO Performance Award framework, which ensure that Elon was only paid for the performance delivered and incentivized to guide Tesla through a period of meteoric growth. The 2025 CEO Performance Award similarly challegnes Elon to again meet a series of even more aspirational goals, including operational milestones focused on reaching Adjusted EBITDA targets (thresholds that are up to 28 times higher than the 2108 CEO Performance Award’s top Adjusted EBITDA milestone) and rolling out new or expanded product offerings (including 1 million Robotaxis in commercial operation and delivery of 1 million AI Bots), all while growing the company’s market capitalization by trillions of dollars.
Yes, you read that correctly: in 2018, Elon had to grow Tesla by billions; in 2025, he has to grow Tesla by trillions — to be exact, he must create nearly $7.5 trillion in value for shareholders for him to receive the full award.
In addition to these unprecedented performance milestones, the 2025 CEO Performance Award also includes innovative structural features, born out of the special committee’s considered analysis and extensive shareholder feedback. These features include supercharged retention (at least seven and a half years and up to 10 years to vest in the full award), structural protections to minimize stock price volatility due to administration of this award and, thereafter, incentives for Elon to participate in the Board’s continued development of a framework for long-term CEO Succession. If Elon achieves all the performance milestones under this principle-based 2025 CEO Performance Award, his leadership will propel Tesla to become the most valuable company in history.”
Musk will have a lot of things to accomplish to receive the 423,743,904 shares, which are divided into 12 tranches.
However, the Board feels he is the right person for the job, and they want him to remain the CEO. This package should ensure that he stays with Tesla, as long as shareholders feel the same way.

Tesla Robotaxi app download rate demolishes Uber, Waymo all-time highs
After two and a half months of testing with a group of hand-picked Tesla influencers and some media, the company has officially launched Robotaxi rides in both Austin, Texas, and the California Bay Area to the public.
Tesla launched its Robotaxi app to the general public yesterday, and the number of downloads is a testament to the platform’s high demand for testing.
After two and a half months of testing with a group of hand-picked Tesla influencers and some media, the company has officially launched Robotaxi rides in both Austin, Texas, and the California Bay Area to the public.
Tesla Robotaxi makes major expansion with official public app launch
Downloading the app is available to iOS users, so if you have an iPhone, you can get it and join the waitlist. Tesla has not yet launched the Robotaxi app for the Android platform, but did hint that it would be coming soon.
The testing phase with the group Tesla selected has gone well. In Austin, the City has only listed one “Safety Concern” with Robotaxi during the testing phase. For the most part, things have gone extremely well, and riders have had good things to say.
Tesla is still operating with some safeguards in place, such as Safety Monitors and Safety Drivers, but these are precautionary and temporary; CEO Elon Musk has said they should be removed by the end of the year.
Elon Musk says Tesla will take Safety Drivers out of Robotaxi: here’s when
Even still, Tesla Robotaxi is something that many people want to experience, and the app downloads prove it.
The Tesla Robotaxi app was downloaded at a rate that exceeded all rolling 30-day periods of both Uber and Waymo, according to Brett Winton of ARK Invest. Tesla’s Robotaxi’s first day on the App Store exceeded Uber’s by 40 percent and Waymo’s best download day ever by six times:

The surge in downloads is a good indication of how in demand the Robotaxi suite was, as many people within the community had vocalized their requests to try the platform, but Tesla was not ready to expand it beyond its handpicked group.
The expansion of the program will result in more rides, provided Tesla continues to expand its fleet of vehicles. It has already admitted many of those who were initially placed on the waitlist.

Elon Musk’s xAI expands to Seattle with salaries up to $440,000
The move was announced by the artificial intelligence startup and Elon Musk on social media platform X.
Elon Musk’s artificial intelligence startup xAI is opening a new office in Seattle as it accelerates its global expansion.
The move was announced by the artificial intelligence startup and Elon Musk on social media platform X. xAI is also hiring for its first positions in the new site.
New Seattle office
As could be seen on xAI’s Careers webpage, the Seattle office is currently hiring for three engineering roles. Each of the three technical roles tied to the new site carry salaries ranging from $180,000 to $440,000.
The new office adds to xAI’s growing presence, which now spans San Francisco, Austin, London, Dublin, New York, and Memphis. The Seattle-based roles focus on video and image generation systems, signaling Musk’s intent to challenge rivals like OpenAI and Meta in generative AI.
Pressures and challenges
Seattle also places xAI within reach of Microsoft’s headquarters in Redmond. Microsoft has emerged as a central player in the AI race through its multibillion-dollar partnership with OpenAI, making xAI’s move into the region notable. The competition for AI specialists has pushed salaries higher across the industry, with filings showing OpenAI staff earning up to $530,000 and Anthropic engineers as much as $690,000 annually, as noted by Insider.
The startup has also seen some high-profile departures in recent months, including cofounder Igor Babuschkin and general counsel Robert Keele. Still, xAI continues to grow aggressively, and its Grok large language model has been gaining momentum among mainstream users. Work also continues to be underway to further build out the company’s Colossus supercomputer cluster. Reports have also suggested that xAI has moved into San Francisco offices in the Mission District, a site Musk initially leased during OpenAI’s early years.
