SpaceX CEO Elon Musk’s hat is safe after ULA Vulcan rocket launch slips to 2023
In the latest unfortunate development for SpaceX competitor United Launch Alliance’s next-generation Vulcan Centaur rocket, it looks like CEO Elon Musk may have been right all along when he forecast major delays more than three years ago.
In February 2018, even before SpaceX had flown Falcon Heavy for the first time, detractors with axes to grind were already busy attempting to downplay the rocket’s capabilities. On February 6th, Falcon Heavy lifted off for the first time, launching a several-ton Tesla Roadster car into interplanetary space and marking the first debut of a super heavy-lift rocket since the 1980s. That successful launch also meant that ULA’s last bastion of competitive advantage – the Delta IV Heavy rocket, fittingly by way of monopoly – was no longer alone.
Indeed, mere months after its near-flawless debut, Falcon Heavy had already secured its first operational US military launch contract. Delta IV Heavy, on the other hand, had already been preparing for retirement as part of ULA’s plan to replace two complex rockets (Delta and Atlas) with Vulcan.
Musk mercilessly took to task ULA’s heavy-lift rocket when commenters brought it up, noting that Falcon Heavy is largely comparable in a partially-reusable configuration but completely outclasses Delta IV Heavy – while still being dramatically cheaper – if all boosters are expended. The SpaceX CEO estimated that Delta IV Heavy launches would cost ULA significantly more than $400M after the company had effectively announced the end of Delta IV Medium production, though ULA CEO Tory Bruno still claimed a launch price of ~$350M.
In response to a reply noting that ULA’s plan was to replace Atlas V and Delta IV with Vulcan Centaur for launches “after 2020,” Musk pulled no punches, stating that he would “seriously eat [his] hat with a side of mustard if [Vulcan] flies a national security spacecraft before 2023.” At the time, ULA’s CEO did not exactly seem to share Musk’s shocking appraisal of the situation, which was out of left field even for major SpaceX proponents.
At the time, ULA’s party line touted Vulcan Centaur lifting off for the first time in late 2019 – the very next year. Ironically, weeks after Musk threw down his hat-eating gauntlet, ULA announced that Vulcan’s first launch had slipped to “mid-2020” – with a second flight later the same year – to give the company time to move straight to a larger upper stage originally meant to debut later on. Six months later, ULA announced yet another delay for Vulcan, this time pushing the rocket’s launch debut from mid-2020 to no earlier than (NET) April 2021.
Three years later, April 2021 has come and gone and ULA’s latest public Vulcan launch target is now “late 2021,” though that is all but guaranteed to slip into early 2022. In the latest (not-so-) shocking development for ULA’s next-generation rocket, the company has now requested and received permission from the US military to swap out Vulcan for an Atlas V rocket on what would have been the vehicle’s first military launch.
Exercising a contract loophole that had to have been explicitly designed to give ULA – and ULA alone – the option to fall back on its Atlas V or Delta IV rockets if Vulcan were to experience major delays, Atlas V will now take over the ULA’s USSF-51 mission. As a result, Vulcan Centaur’s first dedicated ‘national security’ launch is now officially scheduled no earlier than 2023, saving Elon Musk from having to eat his hat.
As of May 2021, ULA has now replaced one Vulcan launch with an Atlas V and inexplicably closed nine Atlas V launch contracts with Starlink competitor Amazon, bringing into question whether the company is ever actually going to simplify its rocket production lines. Given that ULA no longer appears to be planning on reusing parts of Vulcan, the only possible way Vulcan will end up more affordable than the rockets its replacing is if it quickly becomes the only rocket ULA produces, which was originally the plan. With ULA now apparently going out of its way to sell Atlas V commercially instead of Vulcan Centaur, it’s difficult to argue that the company has any interest at all in lowering the cost of access to space or offering SpaceX serious competition outside of lobbying and greasing the hinges of revolving doors.

Tesla revamped Semi spotted, insane 1.2 MW charging video releases
These developments highlight Tesla’s ongoing refinements to the vehicle’s design and infrastructure.
Tesla is gearing up for high-volume Semi production in 2026, with the Class 8 all-electric truck’s revamped variant being spotted in the wild recently. Official footage from Tesla also showed the Semi achieving an impressive 1.2 MW charging rate on a charger.
These developments highlight Tesla’s ongoing refinements to the vehicle’s design and infrastructure.
Revamped Tesla Semi sighting
Tesla Semi advocate @HinrichsZane, who has been chronicling the progress of the vehicle’s Nevada factory, recently captured exclusive drone footage of the refreshed Class 8 truck at a Megacharger stall near Giga Nevada. The white unit features a full-width front light bar similar to the Model Y and the Cybercab, shorter side windows, a cleared fairing area likely for an additional camera, and diamond plate traction strips on the steps.
Overall, the revamped Semi looks ready for production and release. The sighting marks one of the first real-life views of the Class 8 all-electric truck’s updated design, with most improvements, such as potential 4680 cells and enhanced internals, being hidden from view.
1.2 MW charging speed and a new connector
The official Tesla Semi account on X also shared an official video of Tesla engineers hitting 1.2 MW sustained charging on a Megacharger, demonstrating the vehicle’s capability for extremely rapid charging. Tesla Semi program lead Dan Priestley confirmed in a later post on X that the test occurred at a dedicated site, noting that chargers at the Semi factory in Nevada are also 1.2 MW capable.
The short video featured a revamped design for the Semi’s charging port, which seems more sleek and akin to the NACS port found in Tesla’s other vehicles. It also showed the Tesla engineers cheering as the vehicle achieved 1.2 MW during its charging session. Dan Priestley explained the Semi’s updated charging plug in a post on X.
“The connector on the prior Semi was an early version (v2.4) of MCS. Not ‘proprietary’ as anyone could have used it. We couldn’t wait for final design to have >1MW capability, so we ran with what had been developed thus far. New Semi has latest MCS that is set to be standard,” the executive wrote in a post on X.

Tesla FSD successfully completes full coast-to-coast drive with zero interventions
Tesla community members celebrated the milestone on X, and the feat earned praise from some of the electric vehicle maker’s executives.
A Tesla owner has successfully completed a full coast-to-coast drive across the United States on Full Self-Driving (FSD) Supervised. The trip was accomplished with zero interventions.
Tesla community members celebrated the milestone on X, and the feat earned praise from some of the electric vehicle maker’s executives.
FSD Coast-to-Coast
The coast-to-coast feat was accomplished by Tesla owner Davis Moss, who drives a stealth gray Model 3 with AI4 hardware. Based on data from the FSD database and a community tracker, the last 10,638.8 miles Moss drove in his Model 3 were completed using FSD 100% of the time. His vehicle is equipped with FSD v14.2.1.25, which was installed 12 days ago.
As per Moss in a celebratory post on X, his Model 3 was able to complete a full coast-to-coast drive across the United States in 2 days and 20 hours. His trip started at the Tesla Diner in Los Angeles, CA, and it ended in Myrtle Beach, SC. Overall, his trip spanned 2,732.4 miles.
“This was accomplished with Tesla FSD V14.2 with absolutely 0 disengagements of any kind even for all parking including at Tesla Superchargers,” Moss stated in his post. He also added in later comments that there were zero close calls during the trip.
Tesla community celebrates
The FSD milestone trip was widely lauded by members of the Tesla community, especially since a coast-to-coast drive with zero interventions has been cited by Elon Musk as a target since October 2016, when Autopilot 2.0 was unveiled. At the time, Musk initially estimated that a coast-to-coast drive across the United States should be possible by the end of 2017. Considering Moss’ feat in his Model 3, it appears that Elon Musk’s estimate was not impossible at all. It was just late.
Musk himself celebrated the milestone on X, and so did Tesla VP of AI Software Ashok Elluswamy, who wrote “World’s first fully autonomous coast-to-coast drive, done with Tesla self-driving v14. Congrats and thank you @DavidMoss!” in a post on X. The official Tesla North America account also celebrated the feat, writing “First Tesla to drive itself from coast to coast w/ FSD Supervised. 0 interventions, all FSD” on X.

Elon Musk: Tesla Model Y is world’s best-selling car for 3rd year in a row
The Model Y has now established an impressive streak that would otherwise have been impossible before Tesla.
Elon Musk has announced that the Tesla Model Y has become the world’s best-selling car by volume for the third consecutive year, capping 2025 with another dominant performance.
The Model Y has now established an impressive streak that would otherwise have been impossible before Tesla.
Three years in a row
Musk posted on X: “Tesla Model Y is now officially the world’s best-selling car for the third year in a row!” The CEO’s comment echoed an update that Tesla included in its 2025 recap, which highlighted, among other things, the Model Y’s incredible streak.
The Model Y has held the title since 2023, outperforming traditional leaders like the Toyota RAV4 and Corolla thanks to its bang-for-the-buck nature and its stellar combination of practicality, performance, and tech. The Model Y is also lauded as one of the safest vehicles on the road, making it an ideal choice for families in key markets such as China.
An impressive 2025
The Model Y’s sales feat in 2025 is especially impressive considering the introduction of the vehicle’s new variant. Tesla’s changeover to the new Model Y across its global factories resulted in sales being paused for some time in the first quarter. As per Tesla’s Q1 2025 vehicle delivery and production report, “the changeover of Model Y lines across all four of our factories led to the loss of several weeks of production in Q1.”
This suggests that the Model Y’s sales remained strong in 2025 to the point where it could still claim the title of the world’s best-selling vehicle by volume, even with its sales being throttled during the first quarter of the year. It would then be interesting to see just how far the Model Y can go in 2026, especially considering the rollout of new variants like the six-seat extended wheelbase Model Y L, the affordable Model Y Standard, and the top-tier Model Y Performance.
