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.

The showcase emphasized practical features tailored to the needs of the blind community. Braille lettering appears on physical controls, including door releases and emergency buttons, allowing users to navigate interfaces independently through touch. Generous interior space accommodates service animals and assistive devices such as canes, guide dogs, or mobility aids without compromising comfort.
Wheelchair-height seating facilitates easier transfers for users with additional mobility challenges. Photos from the event captured blind attendees approaching the vehicle confidently, service dogs relaxing inside, and hands exploring Braille-equipped handles.
Tesla Robotaxi’s official account detailed these elements, noting the Cybercab’s focus on accessibility, especially noting the Braille lettering and additional space for service animals.
How Tesla Will Transform Mobility for the Blind
Autonomous vehicles like the Cybercab promise revolutionary independence for the roughly 2.2 million visually impaired Americans. Traditional barriers—reliance on sighted drivers, costly paratransit, or limited public transit—often restrict spontaneous travel. Tesla Full Self-Driving aims to eliminate the need for a human operator, enabling on-demand, door-to-door rides via simple app hailing with voice guidance.
Users gain freedom to work, socialize, shop, or attend events anytime without scheduling hassles or safety concerns. This reduces isolation, boosts employment opportunities, and enhances quality of life, turning mobility from a dependency into true personal autonomy.
The NFB demonstration not only gathered valuable feedback but also generated excitement about a future where technology levels the playing field. By prioritizing inclusive design, Tesla advances a vision of transportation that serves everyone, potentially reshaping daily life for blind individuals and setting a standard for the autonomous industry.
As Cybercab deployment scales, these accessibility innovations could mark a significant step toward equitable mobility.

Tesla challenges startups to score a gig inside its most advanced European factory
Tesla is challenging startups to bring their best battery tech directly to Gigafactory Berlin.
Tesla has issued an open challenge to startups across Europe, inviting them to bring their best battery technology directly to the floor of Gigafactory Berlin. The program, called the JUNI x Tesla Battery Cell Giga Challenge, opened applications this month with a deadline of July 24, 2026, and is targeting startups with solutions that can make battery cell manufacturing faster, cheaper, safer, and more scalable at an industrial level.
The timing of the challenge is directly tied to Tesla’s most aggressive European battery investment yet. On May 12, 2026, Giga Berlin plant manager André Thierig announced a $250 million investment to scale the factory’s annual 4680 cell production capacity from 8 GWh to 18 GWh, more than doubling the previous target set just months earlier in December 2025. Thierig confirmed the expansion on X, saying the investment “will enable 18 GWh of annual 4680 cell production and create more than 1,500 new jobs.” Combined with a previously announced battery investment at the Grunheide site now approaches $1.2 billion.
Today, we announced a $ 250m investment for our Giga Berlin Cell factory. This will enable 18GWh of annual 4680 cell production and create more than 1500 new jobs. Good news during challenging times for the German industry. pic.twitter.com/ou4SWMfWh9

The challenge is looking specifically for startups with proven solutions across five categories: materials, equipment, operations, automation, and artificial intelligence. Applications are screened directly by Tesla’s cell manufacturing team in Grunheide, and the strongest submissions move through technical discussions, a pitch day in front of Tesla stakeholders, and potentially a paid pilot project with the cell team. Tesla is not looking for ideas at concept stage. The program requires applicants to demonstrate working prototypes, test data, or prior pilots before being considered.
The historical context matters here. Elon Musk first announced plans for what he called the world’s largest battery cell production facility alongside the Giga Berlin car factory back in 2020, targeting up to 250 GWh of annual capacity. Those plans were shelved in 2022 when Tesla shifted its battery investment focus to the United States to take advantage of Inflation Reduction Act incentives. The revival of cell production at Giga Berlin, now backed by over $1 billion in committed capital, represents a return to an ambition that was set aside for three years. As Teslarati has reported, the 4680 format is central to Tesla’s long-term cost reduction strategy across vehicles, energy storage, including the Tesla Semi and Cybercab.
By opening the challenge to outside startups, Tesla is acknowledging that reaching 18 GWh at Grunheide will require technology it does not currently have in-house, and it is willing to pay for the right solutions. For a startup in the battery supply chain, a paid pilot with Tesla’s European cell team is as close to a direct commercial path as the industry offers.
A Texas man has been arrested and charged with manslaughter after his Tesla crashed into a home last month, striking a woman inside and killing her. The driver, Michael Butler, claimed the vehicle was in self-driving mode, but information from Tesla shows that Butler overrode the system.
Butler was arrested on Wednesday and booked at the Harris County, Texas, jail. He remained in custody through Thursday and Friday; he did not enter a plea, and his next court hearing is scheduled for Monday.
Tesla finally clarifies fatal Texas crash, confirms driver manually overrode acceleration
There are a handful of new clues in the case that could clear Tesla of any wrongdoing, especially as the woman who was killed’s family, the Avilas, filed a wrongful death lawsuit against Tesla and Butler, seeking at least $1 million in damages.
Charging documents from the Harris County prosecutor now show that Butler, who was working DoorDash the evening of the accident, had been using Full Self-Driving mode without incident through the duration of multiple deliveries that evening.
In the moments leading up to the crash, while in FSD and approaching a left turn, Butler pressed the accelerator pedal, overriding FSD’s speed control, and continued to push it until it reached 100 percent. This caused rapid acceleration; the brake pedal was never pressed, and there is no data to show that Butler aimed to turn away from the curb or house.
The charging documents state:
“I noted that the brake pedal was never pressed in the final minute before the crash. I also did not see any data to indicate that the driver attempted to turn away from the curb that he eventually struck. Further, I observed that no mechanical error was detected or recorded by the vehicle before BUTLER and the Tesla struck the curb.”
Additionally, a forensic analysis of Butler’s phone showed that he searched Google around the time of the crash with queries questioning why FSD was “too timid,” “not aggressive enough,” and even searched, “FSD is not aggressive enough for city driving.”
The documents outlined this:
“Investigator Veal also informed me that he had received BUTLER’s cell phone from Deputy Amad and that HDAO digital forensics team had completed a data extraction and download of the phone. Multiple Google searches related to Tesla had been made from BUTLER’s phone in the months leading up the crash. I noted multiple searches in May of 2026 indicating an apparent frustration with Tesla’s FSD mode, including the following searches: “Tesla fsd not aggressive enough 2026 model,” “Tesla fsd not [sic) aggressive enough 2026,” “FSD is not aggressive enough for city driving,” and “tesla fsd too timid.”‘
Tesla had claimed just after the crash that its internal data showed Butler had overridden the system’s speed control and pressed the accelerator completely, causing the vehicle to travel at an excessive rate of speed. Eventually, the car slammed into Avila’s house, killing her.
Butler has now been formally charged with Manslaughter, a felony.
