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.

Tesla Cybercab display highlights interior wizardry in the small two-seater
Photos and videos of the production Cybercab were shared in posts on social media platform X.
The Tesla Cybercab is currently on display at the U.S. Department of Transportation in Washington, D.C., and observations of the production vehicle are highlighting some of its notable design details.
Photos and videos of the production Cybercab were shared in posts on social media platform X.
Observers of the Cybercab display unit noted that the two-seat Robotaxi provides unusually generous legroom for a vehicle of its size. Based on the vehicle’s video, the compact two-seater appears to offer more legroom than Tesla’s larger vehicles such as the Model Y, Model X, and Cybertruck.
The Cybercab’s layout allows Tesla to dedicate nearly the entire cabin to passengers. The vehicle is designed without a steering wheel or pedals, which helps maximize interior space.
Footage from the display also highlights the Cybercab’s large center screen, which is positioned prominently in front of the passenger bench. The display appears intended to provide entertainment and ride information while the vehicle operates autonomously.
Images of the vehicle also show an additional camera integrated into the Cybercab’s C-pillar. The extra camera appears to expand the vehicle’s field of view, which would be useful as Tesla works toward fully unsupervised Full Self-Driving.
Tesla engineers have previously explained that the Cybercab was designed to be highly efficient both in manufacturing and in operation. Cybercab Lead Engineer Eric E. stated in 2024 that the Robotaxi would be built with roughly half the number of parts used in a Model 3 sedan.
“Two seats unlocks a lot of opportunity aerodynamically. It also means we cut the part count of Cybercab down by a substantial margin. We’re gonna be delivering a car that has roughly half the parts of Model 3 today,” the Tesla engineer said.
The Tesla engineer also noted that the Cybercab’s cargo area can accommodate multiple golf bags, two carry-on suitcases, and two full-size checked bags. The trunk can also fit certain bicycles and a foldable wheelchair depending on size, which is quite impressive for a small car like the Cybercab.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.
