SpaceX gears up for busy year of Falcon Heavy launches
SpaceX is targeting no earlier than January 12th for the fifth launch of Falcon Heavy, the largest and most powerful commercial rocket in the world.
As was the case for the rocket’s third and fourth launches, the main customer behind its fifth launch is the US military. Deemed USSF-67, the mission is also expected to be very similar to Falcon Heavy’s most recent launch, USSF-44. That mission saw the massive SpaceX rocket complete its first direct launch to a geosynchronous orbit ~36,000 kilometers (~22,250 mi) above Earth’s surface, where it deployed a pair of spacecraft carrying several rideshare payloads and satellites. Save for the possibility that the US Space Force included secret payloads on USSF-44, the mission appeared to be more of a rocket test and loose collection of experiments than a major military launch.
USSF-67 will likely be similar. According to the US Space Systems Command (SSC), USSF-67 – like USSF-44 – will carry an Aerojet Rocketdyne Long Duration Propulsive EELV (LPDE) spacecraft as a main payload. Aboard LPDE-3A, which is essentially a satellite without a payload, various stakeholders will install an unknown number of experiments, instruments, and smaller satellites that can be activated or deployed once in orbit. The SSC says [PDF] that “LDPE provides critical data to inform future Space Force programs” and that “the unique experiments and prototype payloads hosted on LDPE-3A [will] advance warfighting capabilities in the areas of on-orbit threat assessment, space hazard detection, and space domain awareness.”

The mission will be Falcon Heavy’s second launch since June 2019 and is scheduled to lift off 72 days after the rocket’s USSF-44 launch, which finally ended its unplanned 1225-day hiatus. The schedule is reminiscent of 2019, when SpaceX launched its second and third Falcon Heavy rockets 75 days apart. The second of those two missions (STP-2) was primarily a test flight for the US Air Force (now the Space Force) meant to both push Falcon Heavy to its limits with a complex trajectory and demonstrate Falcon booster reusability. To accomplish the latter goal, STP-2 reused two of the three Falcon Heavy boosters that supported the rocket’s Arabsat 6A communications satellite launch two months prior. USSF-67 will also reuse both of USSF-44’s Falcon Heavy side boosters.
STP-2 was ultimately a near-flawless success, but endless payload delays left Falcon Heavy with nothing to launch for more than three years. Following its return to flight in late 2022, Falcon Heavy may finally be able to properly stretch its wings in 2023. Of course, this isn’t the first time that’s appeared to be the case. In February 2021, there were many signs that SpaceX was preparing to launch Falcon Heavy in mid-2021. And in late 2021, there were strong signs that SpaceX customers were on track for up to five Falcon Heavy launches in 2022.
Now, for the second time, there are five Falcon Heavy rockets tentatively scheduled to launch this year (2023). But the situation is not identical. Numerous long-delayed payloads like the first ViaSat-3 and Jupiter-3 satellites and the US military’s mysterious USSF-67 and USSF-52 spacecraft are finally on the cusp of crossing their respective finish lines. NASA’s Psyche asteroid explorer spacecraft has also survived a continuation review after running into major software issues that precluded a 2022 launch attempt. And Falcon Heavy finally launched USSF-44 – a chronically delayed mission – in November 2022.
Additionally, four of those five Falcon Heavy launches are tentatively scheduled in the first half of 2023, leaving plenty of margin for major delays in the second half of the year. But until ViaSat-3, Jupiter-3, and USSF-52 actually arrive in Florida and until NASA explicitly confirms that Psyche’s technical issues are resolved, any launch targets should be treated with extreme skepticism.
USSF-67 is thankfully much less uncertain. Like Arabsat 6A and STP-2, USSF-67 will reuse both of the Falcon Heavy side boosters recovered after USSF-44. Mirroring USSF-44, SpaceX will also intentionally expend Falcon Heavy’s new center booster to launch USSF-67 directly to geosynchronous orbit. Most importantly, LPDE-3A – the only confirmed USSF-67 payload – arrived in Florida in November 2022. USSF-67 prelaunch operations are currently running a day or two behind schedule relative to USSF-44, but all evidence indicates that the mission is on track to launch sometime in January 2023.

Rolls-Royce makes shocking move on its EV future
When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.
Rolls-Royce made a shocking move on its EV future after planning to go all-electric by the end of the decade. Now, the company is tempering its expectations for electric vehicles, and its CEO is aiming to lean on its legacy of high-powered combustion engines to lead it into the future.
In a significant reversal, Rolls-Royce Motor Cars has scrapped its ambitious plan to become an all-electric manufacturer by 2030. The luxury British marque announced the decision amid sustained customer demand for traditional combustion engines and shifting regulatory landscapes.
When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.
The move aligned with the industry’s broader push toward electrification, promising silent, effortless power befitting the “Rolls-Royce of cars.”
However, new CEO Chris Brownridge, who assumed the role in late 2023, has reversed course. “We can respond to our client demand … we build what is ordered,” Brownridge stated.
The company will continue offering its iconic V12 engines, which remain a cornerstone of its heritage and appeal to discerning buyers who appreciate the distinctive sound and character. He noted the original pledge was “right at the time,” but “the legislation has changed.”
While not abandoning electric vehicles entirely, the Spectre remains in production, with an electric Cullinan option forthcoming; the decision marks the end of a strict all-EV timeline. Relaxed emissions regulations and slowing EV demand, evidenced by a 47 percent drop in Spectre sales to 1,002 units in 2025, forced the reconsideration.
It was a sign that perhaps Rolls-Royce owners were not inclined to believe that the company’s all-EV future was the right move.
Rolls-Royce joins a growing roster of automakers reevaluating aggressive electrification targets.
Fellow luxury brand Bentley has pushed its full electrification from 2030 to 2035, while continuing to offer hybrids and ICE models. Mercedes-Benz walked back its 2030 all-EV goal, now aiming for about 50% electrified sales while keeping combustion engines into the 2030s. Porsche has abandoned its 80% EV sales target by 2030, delaying models and extending hybrids.
Mainstream giants are following suit. Honda canceled its U.S. EV plans, including the 0-Series and Acura RSX, facing a $15.7 billion hit as it doubles down on hybrids. Ford and General Motors have incurred tens of billions in writedowns, canceling models and pivoting to hybrids amid an industry total exceeding $70 billion in charges.
This trend reflects a pragmatic shift driven by infrastructure gaps, consumer preferences, and policy changes. In the ultra-luxury segment, where emotional connection reigns, automakers are prioritizing flexibility over rigid deadlines, ensuring brands like Rolls-Royce evolve without alienating their core clientele.

Elon Musk teases expectations for Tesla’s AI6 self-driving chip
This optimistic timeline for tape-out—the stage where chip design is finalized before manufacturing—signals Tesla’s push to rapidly advance its silicon capabilities.
Tesla CEO Elon Musk is outlining expectations for the AI6 self-driving chip, which is still two generations away. Despite this, it is already in the plans of the company and its serial entrepreneur CEO, who has high expectations for it.
Musk provided fresh details on the company’s aggressive AI hardware roadmap, spotlighting the upcoming AI6 chip designed to supercharge Tesla’s self-driving tech, humanoid robots, and data center operations.
In a post on X dated March 19, Musk stated, “With some luck and acceleration using AI, we might be able to tape out AI6 in December.”

This optimistic timeline for tape-out—the stage where chip design is finalized before manufacturing—signals Tesla’s push to rapidly advance its silicon capabilities.
The announcement builds on progress with the predecessor AI5. Earlier in January, Musk announced that the AI5 design was “in good shape” and “almost done,” describing it as an “existential” project for the company that demanded his personal attention on weekends.
He characterized AI5 as roughly equivalent to Nvidia’s Hopper class performance in a single system-on-chip (SoC) and Blackwell-level as a dual configuration, but at significantly lower cost and power usage.

Musk highlighted that AI5 “will punch far above its weight” thanks to Tesla’s co-designed AI software and hardware stack, making maximal use of every circuit. While capable of data center training tasks, it is primarily optimized for edge computing in Optimus robots and Robotaxi vehicles.
For AI6, Musk envisions substantial gains. “In the same half reticle and same process node, we think a single AI6 chip has the potential to match a dual SoC AI5,” he explained.
The company is targeting ambitious nine-month development cycles for future chips, allowing rapid iteration to AI7, AI8, and beyond. AI5/AI6 engineering remains Musk’s top time allocation at Tesla, with the CEO calling AI5 “good” and AI6 “great.”
Samsung is expected to manufacture the AI6 chips, following deals worth billions, while AI5 will leverage TSMC and Samsung production. These chips will form the backbone of Tesla’s Full Self-Driving system, enabling safer and more capable autonomy, alongside powering dexterous movements in Optimus bots and efficient inference in expanding data centers.

Musk has also restarted work on the Dojo 3 supercomputer project now that AI5 is progressing. Long-term plans include in-house manufacturing via the Terafab facility.
By accelerating chip development with AI tools, Tesla aims to reduce dependence on third-party GPUs and deliver high-performance, energy-efficient solutions tailored to its ecosystem. Success with AI6 could mark a major milestone in Tesla’s journey toward full autonomy and robotics leadership, though timelines remain subject to manufacturing realities.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket
Space Force drops ULA for SpaceX on GPS launch after Vulcan rocket anomaly investigation halts flights.
The U.S. Space Force announced today it is switching an upcoming GPS III satellite launch from United Launch Alliance’s Vulcan rocket to a SpaceX Falcon 9, a move that is as much a reflection of Vulcan’s mounting problems as it is a validation of SpaceX’s growing dominance in national security space launch. The GPS III Space Vehicle 09, originally contracted to fly on Vulcan this month, will now target a late April liftoff on Falcon 9, marking the fourth consecutive GPS III satellite the Space Force has moved to SpaceX after contracts were originally awarded to ULA.
The immediate trigger is a solid rocket motor anomaly that occurred on February 12 during Vulcan’s USSF-87 mission. Although the payloads reached orbit and ULA declared the mission successful, the company characterized the malfunction as a “significant performance anomaly” and has since paused all military launches on Vulcan pending a root cause investigation.
“With this change, we are answering the call for rapid delivery of advanced GPS capability while the Vulcan anomaly investigation continues,” said Systems Delta 81 Commander Col. Ryan Hiserote. “We are once again demonstrating our team’s flexibility and are fully committed to leverage all options available for responsive and reliable launch for the Nation.”
The broader reality is that SpaceX’s reliability record and launch cadence have made it the path of least resistance for the Pentagon, and bodes well with Elon Musk’s plans to IPO SpaceX sometime this year. Its Falcon 9 is the most flight-proven rocket in history, and the Space Force’s Rapid Response Trailblazer program was specifically designed to enable exactly this kind of provider swap for GPS missions, and effectively building SpaceX’s flexibility into the national security launch architecture by design.
For ULA, the stakes are existential. The company entered 2026 with aspirations of finally turning a corner after years of Vulcan delays, with interim CEO John Elbon pointing to a backlog of over 80 missions as reason for optimism. Meanwhile, SpaceX’s contracts with the Space Force have given it a formal pathway to take on even more national security launches going forward.
The significance of today’s announcement extends beyond one satellite swap. It reinforces that America’s most critical space infrastructure, including GPS, missile warning, and beyond, is increasingly dependent on a single commercial provider.
