SpaceX Cargo Dragon capsule ends its second flawless trip to space and back
On June 4th, SpaceX Cargo Dragon capsule C113 departed from the International Space Station 250 miles (400 km) above Earth’s surface, tapped its thruster ‘brakes’, and reentered the atmosphere soon after.
After a month spent in orbit, the uncrewed Dragon returned more than 1900 kg (4200 lb) to Earth, currently the only operational spacecraft on Earth capable of doing so. Per usual, Cargo Dragon splashed down off the coast of California, was picked up by SpaceX vessel NRC Quest, and arrived at Port of Los Angeles a few hours later. Captured by Teslarati photographer Pauline Acalin in spectacular detail, C113’s second successful orbital mission serves as excellent foreshadowing for a follow-up launch – CRS-18 – that could come as soon as July 21st.
Orbital-class marshmallows
As per usual, Cargo Dragon received a healthy dose of charring during its orbital-velocity Earth reentry, barreling through the atmosphere at a blistering 7.7 km/s (4.8 mi/s, Mach 23). The capsule’s orientation during reentry is essentially seared into its hull by its own heat shield-generated plasma trail, creating the distinct dark-brown and black streaks visible in photos.
Although the visible wear and tear might look dramatic, the reality is SpaceX’s Dragon spacecraft are specifically designed to survive the ordeal of Earth reentry in excellent shape – the ablative heat shield takes nearly all (~99%) of the heating-related stress. Cargo Dragon (and Crew Dragon, for that matter) are just shy of encased in a cocoon of a different type of foam-like thermal protection material, visible as Dragon’s pearly white skin prior to reentry.
Teslarati photographer Pauline Acalin did an exceptional job of capturing the well-done SpaceX spacecraft’s return to shore in all its gritty, flight-proven glory, offering glimpses of Cargo Dragon’s Drago thrusters, parachute/drogue mortar, docking mechanism, and PICA-X heat shield.
CRS-18 crests the horizon
NASA and SpaceX have already scheduled Cargo Dragon’s next launch to the International Space Station on July 21st, a brisk 85 days after CRS-17’s successful launch. To make that date, preparations are already well underway and Cargo Dragon will likely ship from California within the next two weeks if it’s not already in Florida. Having successfully supported Cargo Dragon’s CRS-17 mission one month ago, Falcon 9 B1056.2 is scheduled to become the first flight-proven Block 5 booster to launch a dedicated NASA mission and the space agency is even open to using B1056 for a third time on CRS-19.
Beyond NASA’s Block 5 booster reuse milestone, there is also a good chance that CRS-18 will mark SpaceX’s first launch of an already twice-flown and refurbished Cargo Dragon capsule. Since CRS-10 (February 2017), just one of SpaceX’s seven subsequent Cargo Dragon launches has flown with a new capsule, and all of the company’s remaining CRS missions are expected to use refurbished spacecraft. Although one mystery Cargo Dragon capsule (C107) remains publicly unaccounted for, chances are quite good that CRS-18 will mark the first time a commercial space capsule has reached orbit three times.
Assuming SpaceX’s third refurbishment follows the fairly consistent two-year time scale of past Dragon reflights, Cargo Dragon C106 – the first Dragon SpaceX reused – will likely be CRS-18’s capsule.

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.
