SpaceX bids goodbye to older Falcon 9s with Florida ‘jellyfish’ launch spectacle
SpaceX’s final Block 4 Falcon 9 has completed its second and last orbital mission with a spectacular sendoff visible for hundreds of miles along the East Coast, harkening back to “alien invasion” comparisons that followed an equally stunning SpaceX launch from California last December.
Although the Falcon 9 booster was expended in the Atlantic Ocean minutes after launch, its upper stage remains in orbit in an experimental test of its lifespan, while the mission’s flight-proven Cargo Dragon spacecraft separated from the rocket and headed to the International Space Station with a promise of a possible third orbital reuse in 2019. This mission’s Dragon capsule flew for the first time in late 2016 for the CRS-9 mission and spent the two years since then having its heat shield and other major components refurbished or replaced, likely at a cost to SpaceX less than half that of constructing a brand-new Dragon spacecraft.

According to Jessica Jensen, SpaceX’s Director of Dragon Mission Management, SpaceX’s Dragon refurbishment team has also gotten considerably more efficient over several years of experience reusing the orbital spacecraft, now up to three reflights of three separate capsules. She noted in the postlaunch conference that – if all major components are healthy upon CRS-15’s early-August return to Earth – this capsule could be refurbished for its third mission in as few as months, which would make it one of the last Dragon 1 launches before the upgraded Dragon 2 begins crewed flights and takes over all cargo missions. After CRS-15, five more of those Cargo Dragon flights remain until CRS-2’s 2020 takeover, all of which will utilize flight-proven capsules.

Falcon 9, on the other hand, reached a truly historic milestone today for SpaceX – B1045’s second and final flight marks the last rocket SpaceX will fly that does not feature a number of upgrades designed to dramatically improve booster reusability. Known as Falcon 9 Block 5, all future SpaceX missions (at least until BFR’s debut sometime in the early 2020s) will be launched aboard the upgraded rocket. If it works as intended, Block 5 should theoretically enable a rapid and affordable level of reusability never before achieved by Falcon 9 or any other rocket, for that matter.

While still more than a little disheartening to see a Falcon 9 booster intentionally expended after launch, the spectacle created by B1045’s final flight was fitting, to say the least. Thankfully, the Block 5 takeover of all future SpaceX Falcon 9 and Falcon Heavy launches is likely to also result in a dramatic reduction in SpaceX’s willingness to expend flight-proven rockets after launch. Whereas Block 3 and 4 Falcon 9s were never designed to affordably and safely fly more than two or three times total, minimizing any opportunity cost from expending twice-flown rockets after launch, Block 5 has been purpose-built to allow individual boosters to fly a bare minimum of 10 times with minimal refurbishment and as many as 100 times with regular maintenance. Unless Block 5’s design fails to achieve that level of reusability, SpaceX is extremely unlikely to expend Block 5 boosters unless they have flown a number of times to extract as much value as possible from them.
Up next on SpaceX’s manifest are two back-to-back Falcon 9 Block 5 launches, Iridium-7 from California on July 20 and Telstar 19V from Florida less than 18 hours later. Both Block 5 boosters will be recovered aboard SpaceX’s fleet of drone ships, Just Read The Instructions (JRTI) to the West and Of Course I Still Love You (OCISLY) to the East.

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.
