SpaceX rocket fairing reappears on Mr Steven after six week hiatus
A hop and a skip away from SpaceX’s first Falcon 9 Block 5 recovery, the company’s famous fairing recovery vessel Mr Steven was caught by Teslarati photographer Pauline Acalin performing some unusual maneuvers at sea, hauling what can only have been the intact fairing half recovered after SpaceX’s March 30 launch of Iridium NEXT-5.
Why exactly the fairing half was aboard Mr Steven for high-speed trials and eventual delivery to Berth 240 – SpaceX’s future Mars rocket factory – is not entirely clear. The most obvious explanation is that these new operations are in some way related to Falcon 9 payload fairing drop tests hinted at recently by CEO Elon Musk, tests that would allow the company to hone the accuracy of the autonomous parafoils currently used to recover them. In light of Mr Steven’s newly upgraded net, the goal is to gently catch each fairing before they touch down on the ocean’s surface – per SpaceX’s Hans Koenigsmann, even partial immersion in seawater precludes any future attempts at reuse.

While we originally speculated that water intrusion into the fairing halves’ aluminum honeycomb composite structures – a common failure mode in the history of the material’s use in aerospace – would pose a problem for fairing reuse sans net capture, the actual reason Koenigsmann gave was the fact that the environment inside Falcon fairings must be kept extraordinarily clean to avoid damaging the highly sensitive satellite and spacecraft payloads housed inside. In retrospect, it makes a whole lot of sense that cleaning a fairing thoroughly enough after exposure to seawater/sea spray and its multitudes of organic material, minerals, and simple saltwater could pose an extremely expensive (if not outright intractable) problem for routine reusability. Hence Mr Steven and his wonderfully analog recovery hardware (i.e. a giant net).

- On May 16, he arrived at Berth 240 with fairing half in tow. (Pauline Acalin)
- Note the distinctive yellow netting draped over the fairing stand aboard Mr Steven. It’s unclear if this is actually the new yellow net spotted last week, or if it’s actually webbing dedicated to securing the fairing cradle. (Pauline Acalin)
- It’s unclear why the Iridium fairing has been brought once again to Berth 240, aside perhaps from temporary storage. (Pauline Acalin)
After approximately six weeks of rest after its return to Port of San Pedro aboard Mr Steven, the fairing half found itself speeding around the mouth of Port of San Pedro aboard the net boat Mr Steven on May 16, after which it was carefully offloaded at SpaceX’s recently-leased Berth 240 facilities, set to one day become the company’s first Mars rocket and spaceship factory (currently housed in a giant tent a few miles away).
A careful scan of the day’s aviation activities showed no tracked helicopter flights that could have been involved in fairing drop tests, and it’s equally implausible that SpaceX would choose (or be permitted) to attempt to catch a 1000 kg autonomous parafoil a handful of miles from densely populated Los Angeles. Mr Steven’s distinctive yellow net – a brand new upgrade – was also visibly strewn about the vessel’s deck, over top of a basic wooden fairing stand, atop of which sat the sooty Iridium fairing half. Given the lengthy journey, it has made to be aboard Mr Steven, May 16’s unusual day of testing is presumably just the beginning of a number of outings, perhaps culminating in fairing drop and catch tests with a helicopter.
- Regardless of why it’s there, the contrast of the dilapidated urban landscape and cutting-edge flight-proven rocket hardware is absolutely breathtaking.(Pauline Acalin)
- Jump maybe 6 months ahead, and one can already begin to imagine that the first BFS test article may end up being craned aboard a barge before the exact same backdrop. (Pauline Acalin)
Regardless, the whole event was an incredible spectacle, caught in awesome detail by Pauline Acalin. One can only begin to imagine what other sights might one day – perhaps fairly soon – grace the dramatic dockside space SpaceX now owns at Berth 240.
- It’s difficult to imagine how Mr Steven’s already vast net could plausibly be expanded by a factor of two in each dimension. I certainly can’t wait to see how SpaceX engineers and technicians tackle the task. (Pauline Acalin)

SpaceX Starship Flight 13 faces wrath of the Texas skies
SpaceX pushed Starship Flight 13 to Friday, blaming weather instead of the previous engine issues.
SpaceX called off Thursday’s launch attempt of Starship Flight 13, pushing the mission to Friday because of weather tied to Tropical Storm Bertha. The company confirmed the delay on X, noting “Now targeting Friday, July 24 for Starship’s thirteenth flight test, due to weather. A key objective for the flight test is to get clear imagery from the ground of Starship’s heatshield as it flies at a higher dynamic pressure during ascent, which won’t be possible with today’s weather conditions.”
This is the second delay for Flight 13 in two weeks. SpaceX first tried to launch the mission on July 16, but the countdown ended in an automated abort at T-0 when four of Super Heavy Booster 20’s 33 Raptor engines failed to ignite. Musk said at the time that two Raptors would need to be removed and replaced, as Teslarati reported. The company spent the following week destacking Ship 40 and Booster 20, swapping engines, and running leak checks before restacking the vehicle on Pad 2 Wednesday night, according to Spaceflight Now’s live coverage.
Unlike the engine problem, Thursday’s delay has nothing to do with the hardware. SpaceX wants clean footage of Starship’s heat shield captured from the ground as the vehicle flies through max dynamic pressure, something the storm’s cloud cover over South Texas would not allow. The company said visibility should improve for Friday’s attempt, with the same 90 minute window opening at 5:45 p.m. CT.
Flight 13 will be the second outing for the V3 versions of Starship and Super Heavy, following their debut on Flight 12 in May. The mission carries 20 production Starlink V3 satellites, the first time SpaceX has flown operational satellites rather than mass simulators on Starship. Six of those satellites are fitted with cameras to inspect the heat shield from a different angle during ascent, giving engineers a second data source beyond the ground imagery the weather is currently blocking.
Booster 20 will attempt a boostback burn and a splashdown landing burn in the Gulf of America, while Ship 40 follows a suborbital trajectory toward a landing in the Indian Ocean. The flight plan largely mirrors Flight 12, though the booster will run a more aggressive ascent burn after max Q this time, and the ship’s heat shield includes load sensing tiles meant to measure stress at the higher dynamic pressure SpaceX is targeting.
If Friday’s attempt succeeds, Flight 13 could be the last suborbital test in the program. SpaceX is already looking to push for an orbital flight on Flight 14.
Investor's Corner
Google’s massive stake in SpaceX will shock you
In a striking revelation that underscores the lucrative crossover between Big Tech and space exploration, Alphabet Inc., Google’s parent company, disclosed a massive $94.1 billion equity stake in SpaceX following the rocket company’s blockbuster initial public offering earlier this year.
The disclosure came in Alphabet’s quarterly filing, marking the first time the long-held private investment has been publicly valued at market prices. Google was an early backer, investing alongside Fidelity in 2015 with roughly $500-900 million at a time when SpaceX was valued around $12 billion.
That bet has delivered extraordinary returns, roughly a hundredfold, transforming a strategic play on satellite internet and launch capabilities into one of Alphabet’s largest assets.
Google, $GOOGL, has said they hold $94 billion in SpaceX, $SPCX, shares after IPO.

Of the total holding, approximately $80 billion remains subject to short-term post-IPO lockup restrictions, preventing near-term sales. An additional $14.1 billion faces longer-term restrictions, extending into the third quarter of 2027. This structure limits immediate liquidity but protects against market volatility as SpaceX transitions into public trading.
The SpaceX position contributed significantly to gains in Alphabet’s broader investment portfolio, which also includes a major stake in AI leader Anthropic. Combined, these holdings helped drive nearly $100 billion in investment gains during the second quarter, providing a substantial boost to net income amid ongoing AI spending pressures.
Analysts view the disclosure as validation of Alphabet’s venture strategy beyond its core search and cloud businesses. The investment aligns with deeper ties, including reported multi-billion-dollar deals for AI computing capacity on SpaceX infrastructure. As SpaceX advances Starship flights, Starlink expansion, and ambitious Mars goals under Elon Musk, Google’s stake positions it to benefit from the commercialization of space.
For Alphabet, the windfall highlights how patient, forward-looking bets in transformative sectors can yield outsized rewards. While lockups temper short-term impact, the holding cements SpaceX as a cornerstone of Alphabet’s diversified portfolio in an era where aerospace, AI, and connectivity increasingly intersect. Investors will watch closely as restrictions lift and SpaceX’s public performance unfolds.

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.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
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.
