SpaceX’s second Falcon 9 Block 5 booster reuse closes in as rocket refurb continues
Scheduled on October 7th, SpaceX is roughly three weeks out from the next routine launch of Falcon 9, set to carry the ~2800 kg (6200 lb) Argentinian satellite SAOCOM-1A into a low polar orbit from the company’s Vandenberg Air Force Base launch facilities.
Cocooned inside Falcon 9’s payload fairing during the final days of August, the Earth observation satellite’s launch will mark a number of exciting milestones for SpaceX, including the second reuse of a Block 5 booster and the debut of a California-based rocket landing zone barely 400m (1400ft) from the launch pad.

Previously tasked with launching Iridium’s 7th group of 10 NEXT satellites on July 25th, Falcon 9 B1048 has been assigned as SAOCOM 1A’s ride to orbit, originally expected to refly as early as September 5th and September 28th. Despite the delays, it still appears that B1048 will easily snag the SpaceX record for second fastest booster turnaround – 74 days compared to Block 5 booster B1045’s 71 days gap between launching NASA’s TESS and CRS-15 missions.
According to a number of comments from satellite engineers involved in the launch, most of the month-long slip rested on rocket availability, meaning that SpaceX was having some sort of difficulty with Falcon 9 components. Given photos and official comments showing that SAOCOM-1A was encapsulated in its payload fairing more than 5 weeks before launch (August 30th) and that Falcon 9 Block 5 is a fairly new launch vehicle, especially in a flight-proven configuration, the most logical explanation is that SpaceX is simply being extra cautious and thorough with B1048’s post-flight analysis and refurbishment.
It’s entirely possible that SpaceX engineers and technicians could have managed a ~40-day turnaround to make the original September 5 launch date, but it’s equally likely that some off-nominal characteristics were noted while the booster was being prepped for transport after craning off of drone ship Just Read The Instructions. In fact, B1048’s recovery operations were exceptionally lengthy and in-depth, including an extraordinary few hours during which technicians removed the booster’s Merlin 1D access panels, baring wholly-uncovered rocket engines in full view of a public area. Nothing equivalent has ever been observed over the course of more than a dozen Falcon booster recoveries, perhaps indicating some unique circumstances in the case of B1048.

The most obvious explanation is that those publicly-visible inspections were used to judge whether the flight-proven booster could return directly to SpaceX’s Vandenberg launch pad or needed to make a stop at the company’s dedicated Hawthorne factory and refurbishment facilities. Judging from the month-long slip that transpired, it’s probable that the latter option was selected. Regardless, caution is key when a customer’s payload is on the line.
Once it makes its way to the launch pad for the second time, B1048 will have the opportunity to both become the first Block 5 booster to land on land and the first rocket ever to land at SpaceX’s West Coast Landing Zone (LZ), under construction/development for the last two or so years. Just like its Floridan twins, the California LZ will only be an option for particularly lightweight payloads and lower-energy launch profiles, of which SAOCOM 1A (and 1B) certainly fit the bill.

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.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
