SpaceX’s next Falcon Heavy launch slips into 2021
SpaceX’s next Falcon Heavy launch – set to be the rocket’s fourth overall – has slipped several months into 2021 according to the vice commander of the US Air Force Space and Missile Systems Center (USAF SMC).
Known as AFSPC-44 (now USSF-44), the nature of Falcon Heavy’s next payload remains a mystery. Headed to geostationary orbit, the satellite will likely be involved in military satellite communications, possibly including espionage (also known as signals intelligence or SIGINT). Technically, the USSF-44 mission includes two separate satellites and at least two additional rideshare payloads and will weigh roughly 3.7 metric tons (~8200 lb) at launch.
When the contract was announced, Falcon Heavy was expected to launch USSF-44 no earlier than (NET) Q4 2020. By April 2020, that target was closer to late November or December. Now, four months after that report, Brigadier General Jason Cothern says that SpaceX’s next Falcon Heavy launch is scheduled NET February 28th, 2021.
The delay doesn’t come as much of a surprise. Based on public observation of SpaceX’s Falcon booster production and testing, requiring thousands of miles of extremely conspicuous highway transport, it was already clear that the mission was unlikely to launch this year. Of the six first stages spotted in transport over the last nine months, all were clearly Falcon 9 boosters and lacked any of the telltale parts that distinguish Falcon Heavy side and center boosters.
The most recent ‘core spottings’ – a new Falcon 9 booster headed West after acceptance testing and another preparing for acceptance testing in Texas late last month – all but confirmed that USSF-44 was significantly delayed. Since mid-2019, SpaceX has intentionally slowed down Falcon booster production to focus on the higher-volume production of expendable hardware (fairings and second stages). While the company could technically complete boosters every two weeks if its feet were put to the coals and has generally averaged 10 per year, that figure has dropped closer to 6-8 boosters per year over the last ~18 months.
Coupled with a report that all three of the USSF-44 Falcon Heavy rocket’s boosters would be brand new, the lack of sightings in the wild implied that has yet to ship even one of those complex rockets to McGregor, Texas for acceptance testing. Based on preparations for Falcon Heavy’s April 2019 Block 5 launch debut, the process of testing three new Falcon boosters singlehandedly takes at least three months. Additionally, all three of the Arabsat 6A mission’s new Falcon Heavy boosters arrived in Florida a full two months before launch.
In other words, given that a brand new Falcon 9 booster rolled out of SpaceX’s Hawthorne, CA factory on August 24th and that said factory isn’t really set up for concurrent booster completion, it would take unprecedented feats of manufacturing and testing for Falcon Heavy Flight 4 to be ready to launch less than four months from now (around the turn of the New Year).
In fact, even under the assumption that the next three boosters on SpaceX’s factory assembly line are all for Falcon Heavy Flight 4, the new February 2021 launch date is going to be a tight deadline. There is no evidence that SpaceX production delays are to blame for the USSF-44 launch delay and the coronavirus-related disruption of satellite production is equally – if not more – likely. Either way, SpaceX’s fourth Falcon Heavy launch will have to wait a few extra months. Barring a surprise mission over the next six months, Falcon Heavy Flight 4 will also be SpaceX’s first operational launch directly to geostationary orbit (GEO).

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.
