SpaceX rolls next Starship prototype to the launch pad
SpaceX’s sixth full-scale Starship prototype has rolled from its Boca Chica, Texas factory to a nearby launch pad in a sure sign that preparation for a second hop test is well underway.
Barely a week after Starship SN5 became the first such prototype to take flight, SpaceX has transported the rocket back to an assembly bay and replaced it at the launch pad with Starship SN6. Just shy of a carbon copy of SN5, SN6 was built at the same time with only a few small design tweaks. While SN6 is not exactly the significant upgrade promised to start with Starship SN8, the ship is nevertheless brand new and ready to begin testing.
SN5’s spectacular hop debut – while a major success – still resulted in some minor damage and CEO Elon Musk says that SpaceX will try to reuse the prototype, but it likely needs at least a week or two of inspections and repairs. Thanks to SN5’s success, though, sister ship SN6 has become much more valuable, whereas a failed SN5 hop could have easily consigned both prototypes to the scrap heap to give Starship SN8 priority. Instead, Starship SN6 is now next in line.
Hours after Starship SN5 rolled from pad to factory to take Starship SN6’s place beside SN8 in the assembly bay, the flight-proven rocket’s sister ship hit the open road and arrived at the launch pad after a few-mile journey.
After a brief night spent sitting on its transporter, Starship SN6 was lifted by crane onto the pad’s launch mount – briskly refurbished after SN5’s launch debut just eight days prior – on the afternoon of August 12th. Work to install the rocket on the launch mount continued into the night.
Notably, SpaceX has yet to file additional road closures after two used on August 11th for Starship SN5 and SN6 transport operations. Technically, with Starship SN6 now on the launch pad, SpaceX could feasibly file road closures for SN6’s first major tests just a day or less prior to their start, but it’s more likely that the company is planning to kick off the test campaign late this week or early next.
Like its predecessors, SpaceX will begin by putting SN6 through an ambient-temperature pressure test with nitrogen gas to check for leaks and verify general functionality. Once complete, Starship SN6 will have to pass a cryogenic proof test combined with the simulated ~250-ton (~550,000 lb) thrust of a Raptor engine. By using liquid nitrogen instead of actual methane and oxygen propellant, SpaceX removes the risk of a catastrophic explosion or fire were the unproven ship to leak or burst. Finally, with a proof test complete, teams can install a Raptor engine on SN6 and turn the ship around for its first methalox wet dress rehearsal (WDR), engine preburner, and static fire tests – possibly all in one go if all systems cooperate.
With any luck, SN6 – building off of experience gained from SN5 operations – will have a more streamlined test campaign, culminating in the second-ever hop of a full-scale Starship prototype. According to Musk, SpaceX’s new goal is to perform multiple hop tests until flying Starships (at least at low altitudes) is more or less routine.

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

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.
