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 reaffirms Tesla Semi mass production in 2026
The Tesla Semi factory near Giga Nevada is expected to be capable of producing 50,000 units of the Class 8 all-electric truck per year.

Elon Musk has reaffirmed the Tesla Semi’s mass production date. He mentioned the update in a post on social media platform X during the weekend.
Tesla Semi Factory
The Tesla Semi was initially unveiled in late 2017, and its first deliveries were held in December 2022. Since then, Tesla has only been delivering the Semi to a handful of customers while it builds a dedicated factory for the Class 8 all-electric truck near its Giga Nevada facility.
Drone flyovers of the Tesla Semi factory over the past months have suggested that progress in the construction of the facility has been steady. More recent flyovers have even suggested that Tesla is now busy outfitting the facility with the necessary equipment for the mass production of the Semi.
Elon Musk’s Recent Comments
In a recent comment on X, Elon Musk reiterated the idea that the Semi was indeed expected to be mass produced in 2026. Musk shared his update as a response to a Tesla bull who recalled that Bill Gates did not believe that the Semi was feasible due to the limitations of battery technology. In his response, Musk posted a laughing emoji together with “Tesla Semi will be in volume production next year.”
The Tesla Semi factory near Giga Nevada is expected to be capable of producing 50,000 units of the Class 8 all-electric truck per year. While this number may not be attained by the facility right out of the gate, it would only be a matter of time before the factory manages to hit an optimal production rate.
In a video posted on social media earlier this year, Dan Priestley, who leads the Semi program at Tesla stated that the company is preparing for volume production over the coming quarters. With such a pace, the factory should be able to mass produce the Semi in 2026.

Elon Musk confirms Tesla AI6 chip is Project Dojo’s successor
Tesla’s AI5 and AI6 chips are expected to be rolled out to the company’s consumer products.

Earlier this week, reports emerged stating that Tesla has stepped back from its Project Dojo initiative. While the reports were initially framed as a negative development for the electric vehicle maker’s autonomous driving efforts, CEO Elon Musk later noted on X that Tesla was indeed halting its Dojo initiative.
Elon Musk’s Confirmation
As per Musk, Tesla was shuttering Project Dojo because it does not make sense for the company to divide its resources and scale two different AI chip designs. Dojo, after all, is designed to train the company’s autonomous driving program, and thus, it would not be rolled out to Tesla’s consumer products.
In a series of posts on X, Musk stated that it would make sense to just use Tesla’s AI5/AI6 to train its FSD and Autopilot systems. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk said.
Tesla’s AI5 and AI6 chips are expected to be rolled out to the company’s consumer products, from Optimus to the Cybercab to the next-generation Roadster.
AI6 is Dojo’s Successor
What was particularly interesting about Musk’s comment was his mention of using AI5/AI6 chips for training. As per Musk, this strategy could be seen as “Dojo 3” in a way, since the performance of Tesla’s AI5 and AI6 chips is already notable. Musk’s comment about using AI6 chips for training caught the eye of many, including Apple and Rivian alumnus Phil Beisel, who noted that “AI6 is now Dojo.”
“Dojo is Tesla’s AI training supercomputer, built around a custom chip known as the D1. The D1 and AI5/AI6 share many core design elements, particularly the math operations used in neural networks (e.g., matrix multiplication) and highly parallel processing.
“Dojo had a unique feature: chips arranged in a 5×5 grid using a system-on-wafer design, with etched interconnects enabling high-speed data transfer. In a sense, Dojo will live on as the generalized AI6. Going forward, all efforts will focus on AI6,” the tech veteran wrote in a post on X.
Elon Musk confirmed the Apple alumnus’ musings, with the CEO responding with a “bullseye” emoji. Musk is evidently excited for Tesla’s AI6 chip, which is expected to produced by Samsung’s upcoming Texas fabrication facility. In a post on X, Musk stated that he would personally be walking Samsung’s line to accelerate the output of Tesla’s AI6 computers.

Tesla’s new upgrade makes the Cybertruck extra-terrestrial
The upgrade was announced by the electric vehicle maker on social media platform X.

It took a while, but the Tesla Cybertruck’s rock sliders and battery armor upgrades have finally arrived. The upgrade was announced by the electric vehicle maker on social media platform X, to much appreciation from Cybertruck owners.
Tesla Releases Cybertruck Armor Package
As could be seen in Tesla’s official Shop, the Cybertruck Terrestrial Armor Package is available only for Foundation Series units for now, though non-Foundation Series vehicles should have access to the upgrade around September 2025. Price-wise, the armor package is quite reasonable at $3,500.
For that price, Cybertruck owners would be able to acquire enhanced rock sliders and an underbody battery shield that should allow the all-electric pickup truck to go through harsh terrain without any issues. Each purchase of the Terrestrial Armor Package includes 1 Underbody shield, 1 Left side structural rocker, and 1 Right side structural rocker.
Most importantly, the Armor Package’s price includes shipment to the customer’s preferred Tesla Service Center and installation.
Extra-Terrestrial
Tesla describes its Cybertruck Armor Package as follows: “Get extra-terrestrial. The Cybertruck Terrestrial Armor Package includes enhanced rock sliders and an underbody battery shield to provide greater protection from rocks and debris when off-roading on tough terrain. The rock sliders are constructed from coated steel and the underbody battery shield is constructed from aluminum for greater protection against scraping.”
Initial impressions from a Cybertruck owner who was fortunate enough to test the Armor Package in real-world off-road conditions have been positive. The item’s pricing also seems to be quite appreciated by Cybertruck owners in forums such as the Cybertruck Owners Club, with some members stating that they would be acquiring the package for their own all-electric pickup trucks.
