Elon Musk teases an update to SpaceX’s Mars architecture later this year
Elon Musk and SpaceX are aiming to provide a second update on the company’s Mars architecture plans in late September of this year, likely at the 2017 International Astronautical Congress (IAC) in Adelaide, Australia.
While 2017 has been extraordinarily busy and successful for SpaceX thus far, it has also been a somewhat quiet year for Mars and the technology being developed to colonize it affordably. There was a brief flurry of social media information focused on the testing of the ITS carbon composite test tank revealed at the 2016 IAC, with a few pictures and a video of its transport. This activity, as well as Elon Musk’s Ask Me Anything on /r/SpaceX, occurred a month or two after the 2016 IAC, in October and November.

The only concrete information revealed about SpaceX’s Mars ambitions in 2017 have so far been distributed by Musk over Twitter and in an interview of SpaceX President and COO Gwynne Shotwell a few weeks ago. Musk offered tentative time frames for a possible update of the Mars architecture, stating that he believed it dealt with the far more crucial challenge of how to finance such a large endeavor’s significant R&D costs.

During his 2016 reveal, Musk estimated that something like $10 billion would be required to complete development and initial construction of the Raptor engine and ITS test articles. While it is believed that SpaceX has at least several hundred million dollars of liquid capital available, growing several billion dollars of capital is a much greater challenge that will likely require a different methodology than those typically employed by Musk.
Shotewell also discussed SpaceX’s Mars ambitions off and on during an hour-long interview on The Space Show. Of general interest, she mentioned that the current team working on Mars-related research and development was “tiny”, but that it would become a drastically more resource-intensive priority as the company completes work on the fifth and somewhat final “Block” of Falcon 9 and finishes the work necessary to begin routinely conducting Commercial Crew missions. Shotwell gave a timeline of “soon” for the beginning of Block 4 flights and “end of year” for the introduction of Block 5, which is intended to significantly increase the reusability of Falcon 9 (titanium grid fins are a feature of this strategy). Barring delays or setbacks for SpaceX, this implies that SpaceX will begin aggressively pursuing the concrete development of their Mars architecture as soon as the latter months of 2018 or sometime in 2019.

More specifically, however, Shotwell said that the Raptor test article revealed at the Guadalajara IAC has since conducted “dozens” of tests and is now more seriously considering the engine’s potential utility aboard Falcon 9. The current subscale Raptor components are approximately half the size of the final, operational design, and the need to scale up by as little as a factor of 2 should make the realization of the final design considerably less difficult, and make the testing of the current Raptor far more demonstrative of the operational engine. The exploration of vacuum Raptor as the engine of an upgraded second stage for Falcon 9 would further allow for true on-orbit testing of Raptor, and increasing the performance of S2 would allow for greater flexibility in exploring second stage reuse. Musk and Shotwell have expressed interest in this, particularly given that the second stage is approximately 30% of the cost of every Falcon 9, thus capping any potential cost savings first stage (and fairing) reuse may bring. If SpaceX wishes to lower the cost of launches by a factor of 10 to 100 and bring to life any form of the Mars architecture revealed in Guadalajara, they will have to develop second stage reusability that it is both as rapid, functional, and complete as they soon hope to make first stage reuse.
A fully reusable Falcon 9 would offer the company more cost-effective ways to launch their own profit-driving internet constellation, and could also simply provide deeper profit margins for their main business of commercial launches. However, with Musk having already publicly acknowledged that reusability cost SpaceX approximately $1 billion to develop, SpaceX is certainly already considering the plausibly diminishing returns of diverting more funds and human resources into the continued development of Falcon 9. The most likely outcome is almost certainly some combination of the above goals, whereby SpaceX would delay their Mars exploration timeline by several years and concurrently pursue Falcon 9 second stage reuse and the initial test article development for their Mars architecture, as well as exploring the challenges and intricacies of human spaceflight and deep space exploration with Dragon v2.

Of note, the only known major testing event in 2017 related to SpaceX’s Mars program was observed by a SpaceX fan in February of this year. After successful November 2016 tests of the carbon composite tank in northern Washington state, fans noted that the tank had made an outdoors appearance once more in early February 2017. SpaceX mentioned on Instagram that the following test, the one SpaceX was preparing for in February, was a full cryo test of the tank, meaning that it involved actual high-pressure, supercooled liquid oxygen. Another fan noted several days later that the barge SpaceX was testing the tank aboard returned to port empty, and later observed what looked like several large pieces of the tank test article that reportedly had to be recovered from the sound by divers. The logical conclusion is that the tank was destroyed during its second phase of testing, but the crucial and currently unknown fact of the matter is whether the failure was a result of intentionally destructive testing or defects in what was effectively an experimental engineering article. Further SpaceX talks later this year will likely reveal some level of detail as to what transpired in the testing of that prototype carbon composite tank.
Reasoned speculation aside, the latter months of 2017 have multiple talks, speeches, and hearings planned by SpaceX members like Elon Musk and Tim Hughes, and information on SpaceX’s Mars ambitions and other future prospects will almost certainly be offered. Hughes is to attend a hearing at 9am EST on July 13th for the U.S. Senate on commercial space and will be testifying on the subject as a representative and employee of SpaceX. Just under a week later, Elon Musk is scheduled to be the main keynote speaker at the 2017 ISS R&D Conference. His talk is set to begin at 12:30pm EST on July 19th. A handful of months after that, as mentioned above, Musk may also provide a detailed update on SpaceX’s Mars architecture at the 2017 International Astronautical Congress.
In other words, on top of an aggressive 12 possible launches between August and the end of December, SpaceX fans also can look forward to details, photos, and possibly even more about the company’s Mars efforts over the next several months.

Tesla intertwines FSD with in-house Insurance for attractive incentive
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla intertwined its Full Self-Driving (Supervised) suite with its in-house Insurance initiative in an effort to offer an attractive incentive to drivers.
Tesla announced that its new Safety Score 3.0 will automatically have a perfect score of 100 with every mile driven with Full Self-Driving (Supervised) enabled.
The change is designed to boost customers’ average safety scores and deliver noticeably lower monthly premiums.
The move marks the clearest link yet between Tesla’s autonomous driving technology and its proprietary insurance product. Tesla Insurance already relies on real-time vehicle data—such as acceleration, braking, following distance, and speed—to calculate a Safety Score between 0 and 100. Higher scores have long translated into cheaper rates.
Under the previous system, however, even brief manual interventions could drag down the average, frustrating owners who rely heavily on FSD. Version 3.0 eliminates that penalty for supervised autonomous miles, effectively treating FSD-driven segments as the safest possible driving behavior.
The incentive is immediate and financial. Drivers who keep FSD engaged for the majority of their trips will see their overall score rise, potentially shaving hundreds of dollars off annual premiums.
Tesla framed the update as a direct response to customer feedback, many of whom had complained that the old scoring model punished the very behavior it was meant to encourage.
For now, the program applies only to new policies in six states: Indiana, Tennessee, Texas, Arizona, Virginia, and Illinois.
Existing policyholders are not yet included, a point that drew swift questions from the Tesla community. Many owners in other states, including California and Georgia, expressed hope that the benefit would expand nationwide soon.
The announcement arrives as Tesla continues to roll out FSD Supervised updates and push for regulatory approval of more advanced autonomy. By tying insurance savings directly to FSD usage, the company is putting its own actuarial weight behind the technology’s safety claims.
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla has not disclosed exact premium reductions or the full rollout timeline beyond the six launch states.
Still, the message is clear: the more drivers trust FSD Supervised, the more Tesla Insurance will reward them. In an era when legacy insurers remain cautious about autonomous tech, Tesla is betting that its own data will prove the safest miles are the ones driven hands-free.

Tesla finalizes AI5 chip design, Elon Musk makes bold claim on capability
The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.
Tesla has finalized its chip design for AI5, as Elon Musk confirmed today that the new chip has reached the tape-out stage, the final step before mass production.
But in a brief reply on X, Musk clarified Tesla’s AI hardware roadmap, essentially confirming that the new chip will not be utilized for being “enough to achieve much better than human safety for FSD.”
He said that AI4 is enough to do that.
Instead, the AI5 chip will be focused on Tesla’s big-time projects for the future: Optimus and supercomputer clusters.
Musk thanked TSMC and Samsung for production support, noting that AI5 could become “one of the most produced AI chips ever.” Yet, the key pivot came in his direct answer: vehicles no longer need the bleeding-edge silicon.
And thank you to @TaiwanSemi_TSC and @Samsung for your support in bringing this chip to production! It will be one of most produced AI chips ever.

Existing AI4 hardware, which is already deployed in hundreds of thousands of HW4-equipped Teslas, delivers safety metrics superior to human drivers for Full Self-Driving. AI5 will instead accelerate Optimus robot development and massive Dojo-style training clusters.
The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.
Now, with AI4 proving sufficient, the company avoids costly retrofits across its fleet while redirecting next-generation compute toward higher-value applications: dexterous robots and exponential training scale.
But is it reasonable to assume AI4 enables unsupervised self-driving? Yes, but with important caveats.
On the hardware side, the claim is credible. Tesla’s FSD stack runs end-to-end neural networks trained on billions of miles of real-world data. Internal safety data reportedly shows AI4-equipped vehicles already outperforming average human drivers by a significant margin in controlled metrics (collision avoidance, reaction time, edge-case handling).
Dual-redundant AI4 chips provide ample headroom for the driving task, leaving bandwidth for future model improvements without new silicon. Musk’s assertion aligns with Tesla’s pattern of over-provisioning compute early, then optimizing ruthlessly, exactly as HW3 once sufficed before HW4 scaled further.
Optimus and our supercomputer clusters.
AI4 is enough to achieve much better than human safety for FSD.
— Elon Musk (@elonmusk) April 15, 2026
Unsupervised autonomy, meaning Level 4 or higher, is not solely a compute problem. Regulatory approval remains the primary gate.
Even if AI4 achieves “much better than human” safety statistically, agencies like the NHTSA demand exhaustive validation, liability frameworks, and public trust.
Tesla’s supervised FSD has shown rapid gains in recent versions, yet real-world edge cases, like construction zones, emergency vehicles, and adverse weather, still require driver intervention in many jurisdictions. Competitors like Waymo operate limited unsupervised fleets, but only in geofenced areas with extensive mapping. Tesla’s vision-only, fleet-scale approach is more ambitious—and harder to certify globally.
In short, Musk’s post is both pragmatic and bullish. AI4 is likely capable of unsupervised FSD from a technical standpoint. Whether regulators and consumers agree, and how quickly, will determine if Tesla’s bet pays off.
The company’s capital-efficient path keeps existing cars relevant while pouring future compute into robots. If the safety data holds, unsupervised autonomy could arrive sooner than many expect.

Elon Musk signals expansion of Tesla’s unique side business
Long envisioning the Tesla Diner as more than a charging stop, Musk has clearly adopted the idea that the Supercharger and Restaurant combo is a good thing for the company to have. It’s a blend of classic American drive-in culture with futuristic Tesla flair, complete with a 1950s-inspired design, movie screens, and on-site dining.
Elon Musk has signaled an expansion of Tesla’s unique side business, something that really has nothing to do with cars or spaceships, but fans of the company have truly adopted it as just another one of its awesome ventures.
Musk confirmed on Wednesday that Tesla would build a new Diner location in Palo Alto, Northern California. After hinting last October that it “probably makes sense to open one near our Giga Texas HQ in Austin and engineering HQ in Palo Alto,” it seems one of those locations is being set into motion.
Sure

Long envisioning the Tesla Diner as more than a charging stop, Musk has clearly adopted the idea that the Supercharger and Restaurant combo is a good thing for the company to have. It’s a blend of classic American drive-in culture with futuristic Tesla flair, complete with a 1950s-inspired design, movie screens, and on-site dining.
He first floated broader expansion plans shortly after the LA opening in July 2025, noting that if the prototype succeeded, Tesla would roll out similar venues in major cities worldwide and along long-distance Supercharger routes.
Earlier hints included a confirmed second site at Starbase in Texas, tied to SpaceX operations, underscoring the Diner’s role in enhancing Tesla’s ecosystem behind vehicles.
The Los Angeles location on Santa Monica Boulevard in West Hollywood has served as a high-profile test case. Opened in July 2025 at 7001 Santa Monica Blvd., it features the world’s largest urban Supercharging station with 80 V4 stalls open to all NACS-compatible EVs, over 250 dining seats, rooftop views, and 24/7 service.
The retro-futuristic building replaced a former Shakey’s and quickly became a destination. Tesla reported selling 50,000 burgers in the first 72 days—an average of over 700 daily—drawing crowds with Cybertruck-shaped packaging, breakfast extensions until 2 p.m., and movie screenings.
Palo Alto stands out as a logical next step for several reasons. As Tesla’s longstanding engineering headquarters in the heart of Silicon Valley, the city is home to thousands of Tesla employees, engineers, and executives who could benefit from a convenient, branded gathering spot.
The area boasts high EV adoption rates, dense tech talent, and heavy traffic along key corridors, making a large Supercharger-diner an ideal fit for both daily commuters and long-haul travelers.
Proximity to Stanford University and the innovation ecosystem would amplify its appeal, potentially serving as a showcase for Tesla’s vision of integrated mobility and lifestyle experiences. It could be a great way for Tesla to recruit new talent from one of the country’s best universities.
If Tesla and Musk decide to move forward with a Palo Alto diner, it would build directly on the LA prototype’s momentum while addressing Musk’s earlier calls for expansion near core Tesla hubs.
Whether it materializes as a full confirmation or evolves from these hints remains to be seen, but the pattern is clear: Tesla is testing ways to make charging stops memorable. For EV drivers and enthusiasts alike, a Silicon Valley outpost could blend cutting-edge tech with nostalgic comfort, further embedding Tesla into everyday culture. As Musk’s comments suggest, the future of the Diner looks promising.
