SpaceX Falcon 9 “Block 5” next-gen reusable rocket spied in Texas test site
SpaceX’s next and final generation of Falcon rockets is nearly ready to complete its biggest milestone yet, second only to operational launch. Known as Falcon 9 Block 5, the upgraded booster arrived at SpaceX’s McGregor, TX test facilities and went vertical on the static fire test stand.
Now vertical, that first integrated static fire is likely to occur within a handful of days at most. Once complete, assuming the data it produces do not betray any bugs or serious problems, the booster will be brought horizontal and transported to one of SpaceX’s three launch facilities for its first operational mission.
Why Block 5?
With nary a hint of hyperbole, it’s safe to say that Falcon 9 Block 5 will be the most significant piece of hardware ever developed and fielded by SpaceX. The reason lies in many of the changes and upgrades present in this newest iteration of the rocket. While Falcon 9 B5 and its similarly upgraded Merlin 1D engines include design changes intended to satisfy NASA requirements before SpaceX can be certified to launch humans, the brunt of the upgrades are laser-focused on ease and speed of reusability.

The goal with those upgrades, as publicly stated by numerous SpaceX executives, is to enable as many as 10 flights with a bare minimum of refurbishment and 100 or more launches with intermittent maintenance. To achieve those titanic aspirations, SpaceX has gathered a flood of data and experience earned through the recovery of nearly 20 Falcon 9 and Heavy boosters, as well as the successful reflight and second recovery of several of those same boosters. With that data in hand, the company’s launch vehicle engineers optimized and upgraded the rocket’s design to combat the worst of the extreme forces each booster is subjected to while returning to land (or sea).

As evidenced by photos taken by Gary Blair, one of NASASpaceflight.com‘s most renowned L2 forum contributors, many of the visible differences between Block 5 and previous versions of Falcon 9 are a result of drastically improved and expanded heat shielding of its most sensitive and crucial components. While Falcon 9 B5’s black sections by all appearances look like naked carbon fiber composite, they are likely to be coated with an incredibly heat-resistant material known a Pyron. Portions of the booster that suffer from incidental scorching and extreme heating (aside from the octaweb) appear to have been treated with this material, including a pathway down the side of the rocket known as a raceway. The raceway is a protective enclosure for a variety of cabling and piping, essentially the rocket’s nervous system as well as the home of several the cold gas thrusters it uses to orient itself outside of Earth’s atmosphere.
In the past, SpaceX has used high-quality cork as a quasi-ablative thermal protection system for those same components, including the payload fairing. A major downside of cork, however, is that it is very ablative and tends to come off rather haphazardly in large chunks, all of which must either be spot-fixed or replaced entirely before a booster reflight. By replacing that cork with Pyron or a similar internally-developed material, those sensitive Falcon components may be almost totally insulated from and resistant to temperatures as high as 2300 °F (1200 °C)

Titanium grid fins are another central feature of Block 5, acting as a near-indefinitely reusable replacement for the aluminum grid fins SpaceX has traditionally used. Put through a huge amount of heating during reentry; aluminum grid fins have famously appeared to partially melt during some of the hottest booster recovery attempts. Titanium, a metal with a much higher melting point, will have no such problems, does not need ablative white paint, and certainly appear all but untouched by reentry in the cases of both their June 2017 debut and second flight on Falcon Heavy’s side boosters.
Finally and perhaps most importantly, is the octaweb – the assembly at the base of Falcon 9 responsible for safely transmitting nearly two million pounds of thrust from its nine Merlin 1Ds to the rest of the rocket’s structure, while also taking the brunt of the heat of reentry. Before Block 5, the octaweb was protected from that heating with an ablative thermal protection system, likely around 80% cork and 20% PICA-X, the same material used on Cargo Dragon’s heat shield. Based on comments made privately by individuals familiar with SpaceX, that ablative shielding is to be replaced by a highly heat-resistant metal alloy known as inconel. By ridding Block 5 of ablative heat shielding, SpaceX will no longer have to carefully examine and replace those materials after each launch, removing one of the biggest refurbishment time-sinks.

Combined, these various upgrades are intended to enable Falcon 9’s first stage to be reused almost effortlessly compared to previous iterations. With this vehicle, including the reusable fairing debuted on the launch of PAZ, SpaceX may well be able to achieve Elon Musk’s famous goal of lowering the cost of launch by nearly an order of magnitude. While SpaceX will likely use that cost reduction to first recoup its considerable investments in reusability and Falcon Heavy, major price drops may reach customers soon after. This Falcon 9, in particular, is unlikely to launch for another month or so, but when it does, it is perhaps the biggest step SpaceX has yet taken on the path to routine, rapid, and affordable access to orbit.

Tesla begins groundworks on $10B ‘Project Crystal Sun’ in Texas
Tesla has started to perform earthworks engineering on the roughly 3,000-acre site in Fort Bend County, Texas, advancing the massive $10 billion Project Crystal Sun plan to build a vertically integrated solar manufacturing complex.
Flyover drone footage from S.E. Robinson, Jr. released this morning shows the location under development. Tesla has crews on site performing large clearings, but you can also see equipment staging areas, the use of an existing homestead, and active leveling across a substantial portion of the property.
Tesla has started construction on Project Crystal Sun, its $10B vertically integrated solar factory near Houston, Texas.
The plant will make everything from silicon ingots and wafers to finished cells and panels, with operations targeted for Q1 2029.

Public filings first submitted in July under Texas’s Jobs, Energy, Technology and Innovation Act describe a plant that would manufacture the full solar chain: everything from silicon ingots, wafers, coated cells, and finished modules.
Tesla projects 9,712 permanent jobs by 2033, ramping from roughly 1,900 positions in the first year of operations, plus a peak of about 1,147 construction jobs. Construction is targeted for 2026–2028, with commercial production beginning in the first quarter of 2029. An accompanying economic analysis estimates the project could add roughly $107 billion to Texas GDP over several decades.
Local incentives have cleared major hurdles. Lamar Consolidated Independent School District unanimously approved school-tax limitations in September, and Fort Bend County commissioners approved a package of abatements and related agreements in late October that could extend equipment tax breaks for as long as 35 years.
Tesla had previously indicated it was evaluating a competing out-of-state location.
The effort fits broader statements by Musk that Tesla and SpaceX are each working toward 100 gigawatts of annual U.S. solar manufacturing capacity. If built as described, Project Crystal Sun would stand as one of the largest domestic attempts to create a fully integrated solar supply chain on American soil.
While Tesla has not issued a formal groundbreaking announcement, the visible site preparation and high-profile social media activity represent a concrete step forward for a project that has moved from confidential filings to active earthworks in a matter of months.
Cybertruck
Elon Musk keeps justifying Tesla Cybertruck’s cancelation, but it’s confusing
Elon Musk continues to shed more reasons that justify the cancelation of the Tesla Cybertruck, but some of the reasons for the sunset, as well as the process the company is choosing, do not make a lot of sense.
Musk announced last week on X that Tesla would wind down Cybertruck production in mid-2027, a decision that aims to prioritize Cybercab and its importance to the company’s future and passenger transportation as a whole.
But some of what Tesla and Musk are saying does not seem to make much sense. From the process the company is taking with orders to some of the reasoning for the cancelation, the whole situation seems strange.
With that being said: I totally see the merit in prioritizing Cybercab, but I also believe there is room for Cybertruck, a vehicle that has traditionally had low volumes, especially now at its current price point. If it were not for the cancelation, Cybertruck would sell very few units with the recent price adjustments.
Musk Talks Order Rate vs. Production Rate
The first thing that does not make a lot of sense here is the fact that this morning, Musk said that “The Cybertruck order rate far exceeds our production rate. We will try to make as any as possible before shutting down the line in about 8 months, but will have to return deposits for a lot of people.”
The Cybertruck order rate far exceeds our production rate. We will try to make as many as possible before shutting down the line in about 8 months, but will have to return deposits for a lot of people.
This is not a case of Cybertruck being unprofitable, as has been misreported by legacy media, but rather that the opportunity cost of the complexity of Cybertruck is vastly outweighed by the value of incremental Cybercab production.

Then why is Tesla STILL accepting orders for the Cybertruck if it already cannot fulfill its order log by mid-2027?
There are so many people ordering Cybertruck that will not receive it. If Tesla already is having trouble seeing how it will build its current orders, why would it allow additional ones?
There are going to be a lot of people who are very upset next June or July, all because they placed an order for a truck that Tesla knew it would not have the time to build. At this point, it seems like a better idea from a customer service standpoint to simply stop accepting orders on a certain date, build those trucks, fulfill those orders, and then close production.
Continuing to accept orders at this point seems wildly strange. If anything, it feels like the $59k Cybertruck orderers will be the ones who get the short end of the stick here, but that’s speculation and just a hunch on my end.
If not Cybertruck, then what?
With only the Model 3 and Model Y available for consumers, meaning the general public, to buy, there is now no utility vehicle in the Tesla lineup, and that is definitely a disappointment.
Ford already washed its hands of the Lightning, which means the Rivian R1T will likely be the best-selling EV pickup on the market, dueling with the GMC Hummer Pickup, Chevy Silverado EV, and the GMC Sierra EV. There are several pickups that are set to hit the market soon, like the Slate EV Truck, and Ford’s new EV pickup, the Fathom.
Tesla could provide some some transparency on what it is planning to do with a future pickup or utility design. Musk said in the past that something much cooler than a minivan will be built. Cries for a full-size SUV have been heard by Tesla, but the company seems to adamant on prioritizing ridesharing vehicles instead of vehicles people want for work, climate, or hobbies.
Some clarity here, past the point of “Tesla is still going to build cars” would be nice. Even a simple, “Yes” response from all the people asking if Tesla will build something larger would be more than enough. We don’t need all the details now, but something would be nice.
Closing Thoughts
More than anything, it is important to note that I do believe Tesla is making a tough decision and one that, from a business standpoint, does make sense. However, I also believe that there is room for the Cybertruck in Tesla’s lineup.
One thing I think it’s worth mentioning is Tesla is not that much different from many companies. They do things that are better for the business that will surely upset consumers. The difference is very few companies have a following like Tesla, so when these things happen, they feel very personal.
Add in the fact that Cybertruck has truly become a symbol of Tesla, and people are even more upset about it.
It will all get figured out, but it’s still very confusing when we step back and take a look at the bigger picture.
Elon Musk
SpaceX’s Anthropic deal has a catch, and Elon Musk just addressed it
Elon Musk says SpaceX’s Anthropic compute deal cuts both ways after Chamath floats higher prices.
Elon Musk pushed back on Sunday against the idea that SpaceX’s compute contract with Anthropic is a one way bet, after venture capitalist Chamath Palihapitiya argued the company could use a termination clause to charge the AI lab far more.
“It works both ways, of course. If compute becomes plentiful and cheap, SpaceX revenue will drop. No crying in the casino for either party,” Musk wrote on X Sunday evening, replying to a clip of Palihapitiya’s comments shared by AI commentator Rohan Paul.
On the All-In podcast released Sunday, Palihapitiya said either side can walk away from the agreement on 90 days’ notice. If data center supply tightens, he argued, SpaceX could exercise that option and bring the contract back at two to three times the current price, and Anthropic would have little choice but to accept. He called it “the kingmaking move,” according to BigGo Finance.
The clause itself is not new. SpaceX disclosed in its IPO filings in May that Anthropic would pay $1.25 billion per month for dedicated capacity at its Colossus clusters through May 2029, nearly $45 billion in total, with both companies able to terminate on 90 days’ notice, as Teslarati reported at the time. SpaceX’s later compute deals with Google and Reflection AI carry similar exit terms.
What has changed is the political backdrop. Palihapitiya’s thesis rests on incoming Democratic governors pulling tax incentives for data centers and slowing new construction. In Texas, Gov.-elect Gina Hinojosa campaigned on a moratorium on new data center approvals, and Deutsche Bank analysts warned last week that SpaceX’s Texas compute capacity could face delays. SpaceX and Tesla shares both fell after the midterm results.
A slowdown would favor companies that already own capacity. SpaceX acquired xAI in February and has been renting data centers to outside AI labs before the space is needed for Grok. At the Baron Investment Conference on Friday, Musk said SpaceX was “getting 50 billion a year for 35 billion dollar investments” and that it can bring a data center online in eight or nine months, compared to two and a half years for competitors. He also said SpaceX is tracking toward an annualized revenue rate above $100 billion in December, with a “best guess” of $500 billion by December 2027.
Musk’s reply points to the other side of the clause. Anthropic has signed large compute agreements with Amazon, Google and Microsoft, and if that capacity comes online faster than new construction slows, the AI lab would have its own leverage to renegotiate or leave. Musk has called Anthropic “obviously currently the leader in AI,” and it remains one of SpaceX’s largest compute customers.
SpaceX shares rose more than 2 percent in overnight trading late Sunday after closing Friday at $134.27, according to Stocktwits.
