ULA set to ship Vulcan rocket to Florida for Moon lander launch
After many years of delays, all the parts of the United Launch Alliance’s next-generation Vulcan Centaur rocket are about to converge on Florida for their first launch.
Unveiled in 2015, ULA has been working on Vulcan Centaur since at least 2014. Following Russia’s first illegal invasion of Ukraine, countries around the world attempted to punish the aggressor mainly through economic sanctions. In the US, those sanctions included bans on the import of most Russian aerospace technologies, including the RD-180 engines that still power ULA’s Atlas V workhorse rocket in 2023. In 2014, ULA announced that it would work with Blue Origin to integrate the startup’s BE-4 engine into a new rocket booster to end its reliance on Russian engines.
More than eight years later, that BE-4 engine is finally ready for flight, and the rest of the first two-stage Vulcan rocket appears to be right behind it.

Eastward-bound
In a burst of New Year activity, CEO Tory Bruno confirmed that Vulcan Flight 1’s core stage (booster) has been fully assembled, buttoned up, and loaded onto ULA’s transport ship. The aptly named RocketShip will ferry the booster from ULA’s Decatur, Alabama factory to Cape Canaveral, Florida, where it will enter the final stages of launch preparation at the company’s Cape Canaveral Space Force Station (CCSFS) LC-41 pad.
Simultaneously, ULA has finished proof testing Vulcan’s first Centaur V upper stage, a larger and more advanced version of the Centaur III stage ULA and its predecessors have been flying for decades. Centaur V is almost twice as wide as Centaur III and is designed to hold two and a half times more propellant, enabling significantly higher performance in some scenarios.
Additionally, while ULA has partially abandoned plans for a reusable upper stage called ACES (Advanced Cryogenic Evolved Stage), some of those improvements may still be added to Centaur V. Compared to Centaur III, Centaur V’s longevity in space will grow from 8 to 12 hours. ULA is also developing a “mission extension kit” that will allow it to operate for multiple months – unprecedented for a rocket stage powered by cryogenic propellant.
Photos taken by a local paper appear to indicate that ULA is shipping one or more payload fairing (nosecone) halves alongside Vulcan’s first flightworthy booster. While unconfirmed, it would make sense for ULA to ship Vulcan’s booster and fairing together. Another tweet from Tory Bruno indicates that ULA intends to ship Vulcan’s booster and upper stage together, increasing the odds that all components will be aboard RocketShip when it departs for Florida.
A New Workhorse
Vulcan Centaur is ultimately designed to fully replace ULA’s existing Delta IV and Atlas V rockets. Building and operating two very different rockets simultaneously is undoubtedly one of the reasons that ULA’s launch costs are so much higher than SpaceX’s, and simplifying to a single production line is one clear way to achieve major cost savings. ULA hopes that the simplest version of Vulcan will eventually cost about $100 million per launch – still far more than SpaceX’s base Falcon 9 price [PDF] but potentially more competitive than Atlas V. That’s unclear, though, as Bruno has previously stated that Atlas V’s launch costs have fallen to about $100 million apiece thanks to unrelated cost savings.
Regardless, Vulcan Centaur will be a capable rocket and its price is close enough to SpaceX’s extremely competitive Falcon 9 for it to be a mostly valid option for launch customers who want diversity or want to avoid SpaceX for less rational reasons. Vulcan has secured more than 70 launch contracts thanks to ULA’s intimate relationship with the US military and Amazon’s reluctance to launch its Project Kuiper internet satellites with the company behind Starlink, a direct competitor.
Fitted with two BE-4 engines, six solid rocket boosters (SRBs), and unknown upgrades, ULA says the most capable version of Vulcan Centaur will be able to launch up to 12.1 tons (26,700 lb) to the Moon, 15.3 tons (33,700 lb) to geostationary transfer orbit (GTO), and 27.2 tons (60,000 lb) to low Earth orbit (LEO). To high orbits, the most capable Vulcan variant will fairly competitive with SpaceX’s Falcon Heavy rocket. To low orbits, it will generally match or slightly exceed the performance of an expendable Falcon 9, but likely for a much higher price. By every measure, the simplest and cheapest Vulcan variant is significantly less capable than even a partially reusable Falcon 9 and will likely cost 50-100% more.
Moon or bust
Indicating ULA’s confidence in the unflown rocket, the main target of Vulcan’s first launch is the Moon. Vulcan Flight 1 will carry two main payloads: the first two Amazon Kuiper satellite prototypes and Pittsburgh startup Astrobotic’s first Peregrine Moon lander. After deploying both Kuiper satellites in low Earth orbit, Centaur V will fire up again and attempt to send the 1.3-ton (~2850 lb) Peregrine lander directly to the Moon – also known as a trans-lunar injection (TLI) burn. Developed as part of NASA’s Commercial Lunar Payload Services (CLPS) program, Peregrine will be tasked with entering orbit around the Moon and eventually landing up to 70-90 kilograms (150-200 lb) of payload on the lunar surface.
The first Peregrine Moon lander is fully assembled and currently in the middle of extensive integrated testing. If successful, ULA CEO Tory Bruno says that Vulcan will likely be ready to launch sometime in Q1 2023, though Q2 2023 is more likely.

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.
