Hawthorne, we have a problem: SpaceX has too many boosters
Over the course of two years of concerted effort, SpaceX has matured its program of reusable rocketry into a truly staggering success. Over the 24 months since SpaceX first successful recovery of a Falcon 9 booster, there have been stumbles as recovery improved, but overall the company has accomplished 20 near-flawless landings of boosters over that period. Perhaps more impressively, following a handful of failed recovery attempts in 2016, SpaceX has successfully recovered 15 boosters without incident, with the vast majority of those attempts occurring in 2017.
2017 has ultimately been the best year yet for the launch company, marked by what will likely be 18 successful missions (after Iridium-4) for Falcon 9, five commercial reuses of flight-proven boosters, the activation of three essentially new launch facilities, and numerous additional accomplishments behind the scenes as the inaugural launches of Falcon Heavy and Crew Dragon rapidly approach. The success of reusability is arguably the sticking point here, and that success has meant that SpaceX rapidly accumulated a huge stock of recovered Falcon 9s, often to the extent that Elon Musk sometimes joked about running out of space for boosters.

While it may not be immediately clear if SpaceX is legitimately running out of space with which to store its fleet of boosters, reports of first stages being mothballed or even scrapped suggest that space may indeed be at a premium, or at least indicate that SpaceX is growing increasingly pragmatic as its reuse expertise expands.
This is to say that while there may be room to store a few additional boosters, the reality is that older Block 3 Falcon 9s were simply not designed with an expectation that they would affordably survive multiple reuses. As such, it should come as little surprise that SpaceX is choosing to expend at least a couple of upcoming launches featuring reused boosters. As of December 19, public information indicates that the West Coast launch of Iridium-4 – scheduled for Dec. 22 – will not attempt first stage recovery. While somewhat sad, the decision is entirely rational, and it appears all but certain that Iridium-4 will at a minimum feature an attempt at fairing recovery aboard the highly-modified recovery vessel Mr. Steven.

Public Falcon 9 tracking efforts on forums like Reddit and NASASpaceflight indicate that Block 3 boosters include 1029-1038, all of which debuted with their first launches in 2017, beginning with Iridium-1 in January. Of those ten distinct boosters, only two currently lack any future missions, 1032 and 1038; SpaceX has essentially worked the Block 3 fleet to its end-of-life, and that end will be efficiently sped up by simply expending those final reused boosters if or when they are reflown, Iridium-4 included.
For now, we only use those on super hot reentry missions. Will go to all Ti with Falcon 9 V5, which is a few months away.

Expending those older flight-proven boosters will allow SpaceX to both figuratively and literally replace Falcon 9’s less capable predecessors with Block 4s and eventually Block 5s, both of which are at least marginally more reusable than their predecessors. As reported by Musk himself a few days ago, Falcon 9 Block 5 is expected within a few months. Block 5 has seen considerable modifications made to Falcon 9, and all of those changes are intended to improve ease of reuse: SpaceX’s official goal for the upgrade is to enabled Falcon 9 first stages to be reflown as many as 10 times with little to no refurbishment and a lifespan of 100 flights with significant periodic refurbishment. As a result, it is possible that 2018 might feature a similar period of reused Block 4 launches sans any attempted recoveries.
In the meantime, we can wish the fairing recovery teams the best of luck and mourn several of the pioneers of reusable rocketry. Here’s to hoping that we are treated to a live view of each booster’s demise in homage to their achievements.

Elon Musk confirms xAI’s purchase of five 380 MW natural gas turbines
The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI, Elon Musk’s artificial intelligence startup, has purchased five additional 380 MW natural gas turbines from South Korea’s Doosan Enerbility to power its growing supercomputer clusters.
The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI’s turbine deal details
News of xAI’s new turbines was shared on social media platform X, with user @SemiAnalysis_ stating that the turbines were produced by South Korea’s Doosan Enerbility. As noted in an Asian Business Daily report, Doosan Enerbility announced last October that it signed a contract to supply two 380 MW gas turbines for a major U.S. tech company. Doosan later noted in December that it secured an order for three more 380 MW gas turbines.
As per the X user, the gas turbines would power an additional 600,000+ GB200 NVL72 equivalent size cluster. This should make xAI’s facilities among the largest in the world. In a reply, Elon Musk confirmed that xAI did purchase the turbines. “True,” Musk wrote in a post on X.
xAI’s ambitions
Recent reports have indicated that xAI closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development. The funding, as per the AI startup, “will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products.”
The company also teased the rollout of its upcoming frontier AI model. “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote in a post on its website.

A $20 billion Series E round
As noted by the artificial intelligence startup in its post, the Series E funding round attracted a diverse group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group, among others.
Strategic partners NVIDIA and Cisco Investments also continued support for building the world’s largest GPU clusters.
As xAI stated, “This financing will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products reaching billions of users, and fuel groundbreaking research advancing xAI’s core mission: Understanding the Universe.”
xAI’s core mission
Th Series E funding builds on xAI’s previous rounds, powering Grok advancements and massive compute expansions like the Memphis supercluster. The upsized demand reflects growing recognition of xAI’s potential in frontier AI.
xAI also highlighted several of its breakthroughs in 2025, from the buildout of Colossus I and II, which ended with over 1 million H100 GPU equivalents, and the rollout of the Grok 4 Series, Grok Voice, and Grok Imagine, among others. The company also confirmed that work is already underway to train the flagship large language model’s next iteration, Grok 5.

Tesla (NASDAQ: TSLA) stock received a price target update from Pierre Ferragu of Wall Street firm New Street Research, citing the company’s growing lead in self-driving and autonomy.
On Tuesday, Ferragu bumped his price target from $520 to $600, stating that the consensus from the Consumer Electronics Show in Las Vegas was that Tesla’s lead in autonomy has been sustained, is growing, and sits at a multiple-year lead over its competitors.
CES 2026 validates Tesla’s FSD strategy, but there’s a big lag for rivals: analyst
“The signal from Vegas is loud and clear,” the analyst writes. “The industry isn’t catching up to Tesla; it is actively validating Tesla’s strategy…just with a 12-year lag.”
The note shows that the company’s prowess in vehicle autonomy is being solidified by lagging competitors that claim to have the best method. The only problem is that Tesla’s Vision-based approach, which it adopted back in 2022 with the Model 3 and Model Y initially, has been proven to be more effective than competitors’ approach, which utilizes other technology, such as LiDAR and sensors.
Currently, Tesla shares are sitting at around $433, as the company’s stock price closed at $432.96 on Tuesday afternoon.
Ferragu’s consensus on Tesla shares echoes that of other Wall Street analysts who are bullish on the company’s stock and position within the AI, autonomy, and robotics sector.
Dan Ives of Wedbush wrote in a note in mid-December that he anticipates Tesla having a massive 2026, and could reach a $3 trillion valuation this year, especially with the “AI chapter” taking hold of the narrative at the company.
Ives also said that the big step in the right direction for Tesla will be initiating production of the Cybercab, as well as expanding on the Robotaxi program through the next 12 months:
“…as full-scale volume production begins with the autonomous and robotics roadmap…The company has started to test the all-important Cybercab in Austin over the past few weeks, which is an incremental step towards launching in 2026 with important volume production of Cybercabs starting in April/May, which remains the golden goose in unlocking TSLA’s AI valuation.”
Tesla analyst breaks down delivery report: ‘A step in the right direction’
Tesla has transitioned from an automaker to a full-fledged AI company, and its Robotaxi and Cybercab programs, fueled by the Full Self-Driving suite, are leading the charge moving forward. In 2026, there are major goals the company has outlined. The first is removing Safety Drivers from vehicles in Austin, Texas, one of the areas where it operates a ride-hailing service within the U.S.
Ultimately, Tesla will aim to launch a Level 5 autonomy suite to the public in the coming years.
