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 Roadster’s new patent preps white-knuckle speeds, keeping it grounded
Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.
The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.
🚨 The design uses electrically driven ducted fans, typically shown as a row of four at the rear, powered by the vehicle’s high-voltage battery.
The fans pull air from an underbody inlet, route it through ducts, and expel it from a larger rear outlet that functions as a… https://t.co/CHQB9u9UA3 pic.twitter.com/QVXmWTdggh

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.
Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.
The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.
The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.
Tesla Roadster event requires restricted airspace, and the FAA obliges
The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.
There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.
These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.
Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.
It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong
Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.
Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.
Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.
I’m at Tesla right now and when I walked into their showroom I was shocked to see it basically empty.
I asked one of the people working there where all of the cars are “Gone – it’s the end of the quarter and we’ve sold out of everything… including the display vehicles”So… pic.twitter.com/rN7s3gE6sJ

All the cars are gone from Tesla Century City!
All they have is Model Y L, a self-driving video playing on the background. I guess the best product is no product. Either that or they just sold the showroom cars. pic.twitter.com/mzCjWaXwww

Show room is empty. I asked and they have sold the demo cars too. Delivery numbers better be outstanding! pic.twitter.com/jq5N28Q6tZ

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.
Talking to the guys at the Mechanicsburg showroom on Friday, they couldn’t believe they had ANOTHER hauler coming in of cars for delivery—and each was accounted for
No car just sitting in inventory. They’re expecting a BIG quarter, and this is more than just the Y L https://t.co/ce801GkKVv

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.
In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.
Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

Watch Tesla’s “guardian angel” FSD feature take over for collision evasion
Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.
Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”
The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.
The new Automatic Collision Evasion feature worked flawlessly! FSD reengaged itself just as I was about to hit a curb.
Kudos @Tesla_AI team! 👏 pic.twitter.com/Fbp15HhpL2
— Spencer (@scotsrule08) September 28, 2026
The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.
Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.
Tesla plans big safety improvements for Full Self-Driving v15
Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.
Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
