SpaceX’s spectacular USSF-67 Falcon Heavy launch in photos
On January 15th, SpaceX’s Falcon Heavy rocket lifted off for the second time in 75 days to launch another batch of US military payloads into orbits tens of thousands of kilometers above Earth’s surface.
Six and a half hours later, the US Space Systems Command (SSC) confirmed that Falcon Heavy had again completed the exceptionally difficult launch without issue. To deliver the USSF-67 mission’s payloads directly to geosynchronous orbit (GSO), the giant SpaceX rocket had to sacrifice one of its potentially reusable boosters and complete a complex six-hour ballet of rolls, burns, and spacecraft deployments. And for the second time in a row, Falcon Heavy did so without apparent issue.
In an SSC press release [PDF], Maj. Gen. Stephen Purdy, program executive officer for Assured Access to Space, said that the group “had another fantastic launch today on a Falcon Heavy.” He added that “while the launch itself was impressive,” he was “most proud of the fact that we placed important [national] capabilities into space.” And an impressive launch it certainly was.

A Falcon (Heavy) spectacle
As previously discussed, USSF-67 was Falcon Heavy’s first twilight launch. The extraordinary cadence of SpaceX’s workhorse Falcon 9 rocket, which Falcon Heavy is derived from, caused twilight launches and the incredible light shows they can produce to become a fairly routine phenomena. But just under five years after its February 2018 debut, there had still never been a Falcon Heavy launch ‘jellyfish’ or ‘nebula.’ That thankfully changed on Sunday.
The rocket lifted off just ten or so minutes after sunset and soared into the fading purple skies. Those skies were still relatively bright at ground-level, reducing the amount of contrast, but the resulting light show was still spectacular as Falcon Heavy and its immense exhaust plume ascended back into the sunlight. The artificial sunrise lit up that pillar-like plume with the colors of sunrise and, eventually, bright daylight.
Close-up views enabled by tracking telescopes captured the true drama, which began shortly after Falcon Heavy’s twin side boosters separated from the rocket’s main core stage and upper stage, flipped around, and ignited their engines to fly back to the Florida coast they’d only just lifted off from. As the nine-engine center core continued towards space, each booster fired up one and then three Merlin 1D engines for their boostback burns.
A view from Astronomy Live captured the moment of boostback burn ignition, during which the side boosters visibly blasted ‘craters’ the Falcon Heavy center core’s much more powerful plume. As those plumes interacted, the fluid dynamics and light produced by multiple Merlin 1D engines combined to create chaotic whisps of orange, red, and yellow – akin to an exploding nebula. The moments prior were also spectacular as the two side boosters, lit up by direct sunlight against the nearly black sky, began gently floating away from the center core and spinning around with bursts from several nitrogen gas thrusters – a brief moment of serenity before the violence of engine ignition.
On a chariot of fire
But as Maj. Gen. Purdy noted, the purpose of USSF-67 – spectacle aside – was to carry a number of important payloads into orbit.
“After both side boosters touched down, SpaceX ended its live coverage at the request of the Space Force, reiterating the mission’s secretive customer and nature. The USSF hasn’t confirmed much about the USSF-67 mission’s payloads, but Falcon Heavy is known to be carrying a geostationary communications relay satellite called CBAS-2 and likely built by Boeing. CBAS-2 is joined by Northrop Grumman’s third Long Duration Propulsive EELV or LDPE-3A, a combination of a propulsive kick stage and a satellite. LDPE-3A is carrying a collection of rideshare satellites and payloads and is designed to operate for months in orbit. Using USSF-44 as a guide, the total USSF-67 payload could weigh roughly 3.75 to 4.75 tons (8,250-10,500 lb).”

The same SSC press release provides more detail, noting that LDPE-3A carries two hosted payloads – Catcher and WASSAT. Catcher is a space weather instrument developed by the Aerospace Corporation, while WASSAT is a prototype [PDF] of a wide-angle observation instrument designed to track other satellites in GSO. LDPE is also hosting “three payloads developed by the Space Rapid Capabilities Office (SRCO),” including “two operational prototypes for enhanced situational awareness, and an operational prototype crypto/interface encryption payload providing secure space-to-ground communications capability.”
Two down, one to go
For Falcon Heavy side boosters B1064 and B1065, both of which supported USSF-44 and USSF-67, their missions are far from over. Their second successful side-by-side landing has cleared the boosters to be reused on a third US military launch called USSF-52. Originally known as AFSPC-52, the mission was Falcon Heavy’s first operational US military launch contract and the first time the rocket beat competitor United Launch Alliance (ULA) during a competitive procurement.
Next Spaceflight reports that USSF-52 is scheduled to launch no earlier than April 10th, 2023, less than three months from now. Once that mission is complete, Falcon Heavy will have no more US military missions on contract, although more will almost certainly be rewarded sooner than later. USSF-52 is sandwiched between two other Falcon Heavy launches. Next Spaceflight also reports that Falcon Heavy could launch the ViaSat-3 communications satellite as early as March 2023 and the Jupiter-3 (EchoStar 24) communications satellite as early as May 2023, making for a busy 90 days.
For that trio to happen as scheduled, SpaceX will have to beat Falcon Heavy’s record 75-day turnaround, which has coincidentally (?) occurred twice: first between Arabsat 6A and STP-2, and again between USSF-44 and USSF-67. Including USSF-67, SpaceX has up to five Falcon Heavy launches scheduled this year.

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.
