SpaceX nails reused booster launch, Falcon Heavy’s maiden flight days away

Published

on

Despite a brief 24-hour delay due to weather and minor mechanical issues, SpaceX recycled the launch opportunity and completed the mission on Wednesday afternoon, January 31. Tasked with carrying GovSat-1 to orbit, the reused Falcon 9 rocket (Booster 1032) performed flawlessly and as expected, although the stage was expended. Launch directors confirmed just before the end of the live webcast that the communications satellite, a public-private partnership between SES and Luxembourg, was placed into a good orbit a few minutes before it separated from Falcon 9’s second stage. The mission marks SpaceX’s second successful launch of 2018, its first reused flight of the year, and the last launch before Falcon Heavy’s inaugural flight – currently scheduled for Tuesday, February 6.

Perhaps most intriguingly (or at least uniquely), the to-be-expended booster was still seen outfitted with both grid fins and landing legs at the launch pad, the new legs a stark white against the dark and sooty backdrop of the Falcon 9’s recycled booster. While SpaceX’s webcast host very explicitly stated at least three times that the first stage was not going to be recovered, careful listeners may have still caught snippets of the launch and recovery directors announcing different milestones as Falcon 9 S1 landed softly in the Atlantic Ocean. Similar to the recovery operations after the launch of Iridium-4 in December 2018, S1 flew as if it were landing aboard a drone ship, although in the case of this launch that theatricality extended even to landing legs.

While it may seem quite odd that SpaceX would choose to expend an entire, recoverable rocket, it is presumed that SpaceX is simply choosing to rid itself of a stock of older boosters incapable of flying more than once or twice – preparing for the introduction of the highly reusable Block 5 of Falcon 9, in other words. As stated by the webcast host, a SpaceX engineer, the company’s goal is for boosters to last “tens of launches in the short term, and hundreds or thousands of launches in the long term.” It is worth remembering that expending rocket boosters in the ocean (or even over land for Russia and China) is the status quo of all non-SpaceX rockets, and SpaceX has only just begun to perfect booster recovery and reuse – the first successful ocean recovery was completed less than two years ago. The very fact that it already feels odd or even wrong to “throw away” hardware into the ocean after launch is a testament to just how rapidly SpaceX have changed both the figurative and literal paradigms of orbital rocketry, and it is only a matter of time before the eminently persistent company ends the practice of expendable launches internally, if not globally.

Up next, Falcon Heavy

After yet another successful mission for SpaceX, the company’s Florida efforts will now briefly focus on the imminent inaugural launch of Falcon Heavy, the company’s newest and largest rocket. Loosely penciled in for liftoff on Tuesday, February 6, the massive vehicle will become the most powerful and capable operational rocket in the world, comparable only to the likes of NASA’s Saturn V and Space Shuttle, as well as the Soviet Union’s short-lived Energia. Regardless of its place against a historical backdrop of massive state-funded rockets, Falcon Heavy will by default become the most powerful commercial launch vehicle ever developed, and that title will almost certainly remain uncontested until 2020 at the absolute earliest. If or when the first and smallest version of NASA’s SLS rocket launches, likely also no earlier than 2020, the space agency may well take the crown back for a brief year or so. Regardless, SpaceX will likely be regularly launching Falcon Heavies and nearing the tail end of the development and testing of its much larger BFR rocket and spaceship.

Falcon Heavy will be the clearest progress yet towards such a massive rocket, and will provide SpaceX with invaluable experience and expertise as the only private company to ever operate a super heavy-lift launch vehicle (SHLLV). After a solid four weeks of near-constant testing, bug-fixing, and retesting, Falcon Heavy just days ago completed its first static fire, marking the first point in its history that all 27 of its first stage engines were simultaneously ignited. The data produced by that crucial test was apparently satisfactory, and Elon Musk just yesterday reiterated that the vehicle’s first launch was still targeting February 6.

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.

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.”

Reports from industry watchers in China have suggested that the Tesla Model Y L has started mass production at Gigafactory Shanghai. The vehicle is expected to be a larger version of the best-selling Model Y crossover, offering three rows and six seats thanks to a longer wheelbase.

Tesla Model Y L Production Rumors

Reports about the new Model Y variant’s alleged milestone were initially shared on Weibo, with some industry watchers stating that the vehicle has already started mass production. Tesla China is reportedly surveying which of its domestic stores would have the first display units of the six-seat Model Y. 

The Model Y L’s steady march towards production was evident this past week, with recent reports indicating that the vehicle’s key specs have already been listed in the China Ministry of Industry and Information Technology’s (MIIT) latest batch of new energy vehicle models that are eligible for vehicle purchase tax exemptions.

As per the MIIT’s list, the Model Y L will be a dual motor vehicle that is equipped with an 82.0-kWh lithium-ion battery from LG Energy Solution. The vehicle will feature six seats with two captain seats on the second row, as well as a CLTC range of 751 km. 

Tesla Model Y L Potential

The potential of the Model Y L is vast, considering that it is produced in the existing Model Y lines of Tesla’s factories. This should slash new vehicle tooling costs and potential ramp-up issues. Three-row SUVs also command a pretty notable market that has mostly only been accessed by the more expensive Model X. With the Model Y L’s lower price, Tesla could become more competitive in the three-row SUV segment.

As noted by longtime Tesla owner and investor @_SFTahoe, the Model Y L could also become a more premium option for the company’s Robotaxi business, thanks to its second row captain seats and spacious interior. The expansion of Model Y L Robotaxis should also be impressive considering Tesla’s mastery of mass manufacturing techniques.
