SpaceX CEO Elon Musk explains how Starships will return from orbit
In the near future, SpaceX wants to begin putting its first two full-scale Starship prototypes through a series of increasingly challenging test flights, eventually culminating in their first Super Heavy-supported orbital launch attempts.
SpaceX CEO Elon Musk took to Twitter over the last 48 or so hours to answer a number of questions about how exactly Starship is meant to make it through orbital reentries – by far the most strenuous period for the ship and without a doubt the single most challenging engineering problem SpaceX must tackle.
Discussed yesterday on Teslarati, SpaceX technicians began the process of attaching numerous Tesla Model S/X battery packs to a subcomponent that will eventually be installed inside Starship Mk1’s nose, offering a storage capacity of up to 400 kWh. The need for all that power (Crew Dragon relies on a few-kWh battery) is directly related to Starship Mk1’s methods of reentry and recovery, recently described in detail by Elon Musk.
As noted above, ~400 kWh of batteries are needed to power the electric motors that will actuate Starship’s massive control surfaces – two large aft wings and two forward canards/fins. According to Musk, Starship’s “stability is controlled by (very) rapid movement of rear & fwd fins during entry & landing”, meaning that the spacecraft will need to constantly tweak its control surfaces to remain in stable flight.
By far the biggest challenge SpaceX faces is ensuring that Starship can survive numerous orbital-velocity reentries with little to no wear and tear, a necessity for Starship to be cost-effective. In Low Earth Orbit (LEO), Starship will be traveling no less than 7.8 km/s (Mach 23, 17,500 mph) at the start of atmospheric reentry. In simple terms, the process of slowing from orbital velocity to landing on Earth involves turning the vast majority of that kinetic energy into heat. As Musk noted yesterday, this reality is just shy of unavoidable but there is some flexibility in terms of how quickly one wants to convert that energy into heat.
The fastest route to Earth would involve diving straight into the atmosphere, dramatically increasing peak heating on a spacecraft’s surface to the point that extremely exotic heat shields and thermal protections systems become an absolute necessity. SpaceX wants to find a middle ground with Starship in which the spacecraft uses its aerodynamic control surfaces and body to generate lift, slowly and carefully lowering itself into Earth’s atmosphere over a period of 15+ minutes. Musk notes that this dramatically lessens peak heating at the cost of increasing the overall amount of energy Starship has to dissipate, a bit like cooking something in the oven at 300 degrees for 30 minutes instead of 600 degrees for 10 minutes.
To an extent, Starship’s reentry profile is actually quite similar to NASA’s now-retired Space Shuttle, which took approximately 30 minutes to go from its reentry burn to touchdown. Per the above infographic, it looks like Starship will take approximately 20 minutes from orbit to touchdown, owing to a dramatically different approach once it reaches slower speeds. Originally described by Musk in September 2018 and again in recent weeks, Starship will essentially stall itself until its forward velocity is nearly zero, after which the giant spacecraft will fall belly-down towards the Earth, using its wings and fins to maneuver like a skydiver. The Space Shuttle landed on a runway like a (cement-encased) glider.
This unusual approach allows SpaceX to sidestep the need for huge wings, preventing Starship from wasting far more mass on aerodynamic surfaces it will rarely need. The Space Shuttle is famous for its massive, tile-covered delta wing and the leading-edge shielding that partially contributed to the Columbia disaster. However, it’s a little-known fact that the wing’s size and shape were almost entirely attributable to US Air Force demands for cross-range performance, meaning that the military wanted Shuttles to be able to travel 1000+ miles during reentry and flight. This dramatically constrained the Shuttle’s design and was never once used for its intended purpose.
SpaceX thankfully doesn’t have its own “US Air Force” stand-in making highly consequential demands (aside from Elon Musk ?). Instead, Starship will continue the SpaceX tradition of vertical landing, falling straight down – a bit like a skydiver (or a brick) – on its belly and flipping itself over with fins and thrusters for a propulsive vertical landing. In this way, Starship doesn’t have to be a brick forced to fly, like the Shuttle was – it just needs to be able to stably fall and quickly flip itself from a horizontal to vertical orientation.
Additionally, Starship is built almost entirely out of steel, whereas the Shuttle relied on an aluminum alloy and needed thermal protection over every square inch of its hull. Steel melts at nearly twice the temperature of the Shuttle’s alloy, meaning that Starship will (hopefully) be able to get away with nothing more than ceramic tiles on its windward half, saving mass, money, and time. Once Starship completes its first 20 km (12.5 mi) flight test(s), currently scheduled no earlier than mid-October, SpaceX will likely turn its focus on verifying Starship’s performance at hypersonic speeds, ultimately culminating in its first orbital-velocity reentries.

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:
Today’s Tesla Robotaxi App downloads outpaced Uber across all rolling 30 day periods by 40% and bested Waymo’s best download day ever by >6x pic.twitter.com/s9s1XTsUu2

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.
