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’s $2.9 billion bet: Why Elon Musk is turning to China to build America’s solar future
Tesla looks to bring solar manufacturing to the US, with latest $2.9 billion bet to acquire Chinese solar equipment.
Tesla is reportedly in talks to purchase $2.9 billion worth of solar manufacturing equipment from a group of Chinese suppliers, including Suzhou Maxwell Technologies, which is the world’s largest producer of screen-printing equipment used in solar cell production. According to Reuters sources, the equipment is expected to be delivered before autumn and shipped to Texas, where Tesla plans to anchor its next phase of domestic solar production.
The move is a direct extension of a vision Elon Musk has been building for months. At the World Economic Forum in Davos this past January, Musk announced that both Tesla and SpaceX were independently working to establish 100 gigawatts of annual solar manufacturing capacity inside the United States. Days later, on Tesla’s Q4 2025 earnings call, he made the ambition concrete: “We’re going to work toward getting 100 GW a year of solar cell production, integrating across the entire supply chain from raw materials all the way to finished solar panels.”
Job postings on Tesla’s website reflect that same target, with language explicitly calling for 100 GW of “solar manufacturing from raw materials on American soil before the end of 2028.”
The urgency behind the latest solar manufacturing target is rooted in a set of rapidly emerging pressures related to AI and Tesla’s own energy business. U.S. power consumption hit its second consecutive record high in 2025 and is projected to climb further through 2026 and 2027, driven largely by the explosion in AI data centers and the broader electrification of transportation. Tesla’s own energy division, which produces the Megapack utility-scale battery storage system, has been growing rapidly, and solar supply is a critical companion component for the business to scale. Musk has argued that solar is not just a clean energy option but the only one that makes economic sense at the scale AI infrastructure demands.

Ironically, the path to domestic solar independence currently runs through China. Sort of.
Despite Tesla’s stated push to localize its supply chain, mirrored recently by the company’s plan for a $4.3 billion LFP battery manufacturing partnership with LG Energy Solution in Michigan, Tesla still relies on China-based suppliers to keep its cost structure intact.
The $2.9 billion equipment deal underscores a tension Musk himself acknowledged at Davos: “Unfortunately, in the U.S. the tariff barriers for solar are extremely high and that makes the economics of deploying solar artificially high, because China makes almost all the solar.” Building the factory in America requires buying the machinery from the country Tesla is trying to reduce its dependence on.

The regulatory pathway adds another layer of complexity. Suzhou Maxwell has been seeking export approval from China’s commerce ministry, and it remains unclear how quickly that clearance will come. Still, the market has already reacted, with shares in the Chinese firms reportedly involved in the talks surged more than 7% following the Reuters report that broke the story.
Whether Tesla can hit its 2028 target of 100GW of solar manufacturing remains an open question. Though that scale may seem staggering, especially in such a short timeframe, we know that Musk has a documented history of “always pulling it off” in the face of ambitious deadlines that may slip. But, rest assured – it’ll get done.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.
For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.
For the most part, things are better in terms of overall behavior.
However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”
He added:
“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.
Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.
It’s in testing right now. Wide release in a few weeks.
— Elon Musk (@elonmusk) March 19, 2026
Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.
It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.
What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.
