SpaceX’s Mr. Steven highlights ambiguity of Falcon fairing catches with port return
SpaceX’s fairing recovery vessel Mr. Steven highlighted the maddening and exhilarating uncertainty of unpublicized fairing recovery attempts with a return to Port of San Pedro on October 18th, the morning after spending a day at sea for the second Falcon fairing drop-and-catch test.
Teslarati photographer Pauline Acalin was on site to watch Mr. Steven’s 1AM Pacific port return and was able to capture the arrival, showing a familiar test fairing resting on the vessel’s deck, perfectly intact, with the recovery net fully retracted.
Schrödinger’s Fairing
Beginning with a dry run on October 8th, SpaceX technicians and engineers have spent the last 10 days testing Mr. Steven more intensely than ever previously observed, centering around a campaign of apparent Falcon fairing drop tests. Although it’s possible that these tests are more captive-carry trials than true drop tests, it seems more likely – judging by the fact that NOTAMs, notices to airmen, were only filed for 2 of the 3 attempts – that the helicopter is actually releasing a fairing half around 11,000 feet (3300 m) and letting it glide towards Mr. Steven.
Previously, SpaceX executive Hans Koenigsmann and CEO Elon Musk have mentioned a probable drop test campaign if operational (post-launch) fairing recovery attempts were unsuccessful. Mr. Steven has yet to successfully snag a fairing out of the air over the course of four post-launch catch attempts, evidence that – just like landing Falcon 9 boosters intact – recovering orbital-class rocket hardware in a state that allows for future reuse is extraordinarily difficult, regardless of the subsystem. However, SpaceX has managed to successfully recover fairing halves intact and in a condition good enough to make Koenigsmann, Vice President of Reliability, visibly excited during an IAC 2018 presentation.

The problem with those intact halves is that they have been recovered only after soft landings in the ocean – once immersed in saltwater, the sheer expense of cleaning a fairing to the point that it would be able to host another sensitive satellite payload is apparently too high to be worthwhile, at least from a perspective of economical reusability. The (quite literally) miniscule line that thus appears to be separating failed fairing recovery attempts from successes also means that it’s extraordinarily difficult to know whether the fairing half that returned on Mr. Steven yesterday morning is indicative of a breakthrough success or another successful failure.
Clearly, the fairing is perfectly intact from a purely structural perspective, meaning that its recovery hardware – cold gas thrusters and a parafoil – worked nominally. What is impossible to tell is whether its autonomous guidance systems were able to successfully direct it to Mr. Steven’s net, or whether Mr. Steven himself was able to maneuver beneath the falling fairing in time to catch it. And yet, a fairing half still sits visibly intact on Mr. Steven’s deck, story and fate unknown. With any luck, SpaceX will offer an official confirmation of some sort once success is in hand. For now, we wait.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
In a pointed message on X, Elon Musk warned that firms maintaining significant short positions in SpaceX over time face “very low” survival probability.
The statement comes amid post-IPO volatility for the rocket company, now trading under the ticker $SPCX.

Five weeks after what was described as the largest IPO in history, the stock had fallen roughly 30% from its peak above $2.6 trillion, briefly surpassing Microsoft and Amazon in market value. Short sellers celebrated gains of about $8.7 billion, but Musk’s reply underscores his long-term conviction.
The warning directly echoes a detailed bullish analysis arguing that Starship’s cost reductions could unlock a multi-trillion-dollar space economy. Projects ranging from solar power beamed from orbit and asteroid mining to orbital data centers and Mars terraforming were projected to create over $100 trillion in new market capitalization.
In this vision, SpaceX acts as the essential infrastructure provider, akin to AWS for cloud computing, capturing monopoly-like revenues from launches, crew transport, and data traffic across a rapidly expanding frontier.
This is far from the first time Musk has targeted short sellers. With Tesla, he has repeatedly framed persistent bears as destined for major losses. In July 2024, Musk declared that once Tesla achieves full autonomy and volume production of Optimus robots, “anyone still holding a short position will be obliterated. Even Gates,” referencing Microsoft co-founder Bill Gates’ reported short bets.

Earlier, in 2018, he taunted shorts that they had “about three weeks before their short position explodes,” a remark followed by sharp stock gains. Musk has also called short selling “value destroying” and once suggested it “should be illegal,” viewing it as betting against innovation and progress.
Critics often dismiss Musk’s optimism as hype, especially when near-term metrics like quarterly deliveries or stock fluctuations disappoint.
Yet his pattern remains consistent: framing short positions against his companies as fundamentally misjudging exponential technological leaps. For SpaceX shorts, the message is clear: betting against multi-planetary ambitions and the infrastructure monopoly they enable carries existential risk for the firms involved.
As Musk and supporters see it, the space economy’s upside dwarfs Earth-bound valuation models, making today’s dips temporary in a decades-long ascent.
SpaceX has updated its target for the thirteenth integrated flight test of Starship, aiming for as early as Thursday, July 23. The 90-minute launch window opens at 5:45 p.m. CT from the company’s Starbase facility in South Texas.
The target flight was initially rescheduled for today, but SpaceX pushed it back again.
This latest adjustment follows an aborted attempt earlier in the week and reflects the iterative, rapid-development approach that has defined the Starship program. With the vehicle already stacked and ground teams making final preparations, the mission represents another step toward proving the full reusability of the world’s most powerful rocket system.

The original launch attempt on July 16 was scrubbed at T-0 when several Raptor engines on the Super Heavy booster failed to ignite properly. The automatic abort system triggered just as the engines began their startup sequence, preventing liftoff.
SpaceX CEO Elon Musk confirmed that some engines did not start as expected, prompting the decision to replace two Raptors on Booster 20 to ensure reliability. The issue occurred despite a successful full-duration static fire earlier, highlighting the complexities of coordinating 33 engines under flight conditions.
This cautious approach underscores SpaceX’s commitment to safety amid an aggressive test cadence.
Flight 13 builds directly on the lessons from Flight 12 in May 2026. The Super Heavy booster’s primary goals include a successful liftoff, ascent, stage separation, boostback burn, and controlled splashdown in the Gulf of America.
Hardware and software modifications address the off-nominal flip and boostback burn problems from the prior flight, where propellant slosh and engine relight issues led to an uncontrolled impact.
For the Starship upper stage, objectives include deploying 20 operational Starlink V3 satellites, the first real payload of this type, performing a single Raptor engine relight in space, and executing a controlled entry, descent, and splashdown in the Indian Ocean. Propulsion upgrades aim to improve engine-out capability after one vacuum Raptor was lost on Flight 12.
Additional test elements focus on heat shield performance. Six satellites carry cameras to image the tiles during flight, while white-painted tiles and upgraded attachments on flaps and the aft skirt will gather data for future reusability.
The FAA completed its mishap investigation into Flight 12 earlier this month, clearing the regulatory path.
This suborbital mission, the second with V3 vehicles, advances Starship toward operational missions, including potential crewed flights and support for NASA’s Artemis program. Success would mark significant progress in rapid reusability and satellite deployment from the massive system.
