SpaceX lifts soggy Falcon 9 Block 5 booster ashore after accidental splashdown
Independent group USLaunchReport has published a video capturing the entirety of SpaceX’s ad hoc East Coast Falcon 9 recovery operations, in which forlorn booster B1050 had to be carefully extracted out of the ocean after an unintentional soft-landing in the Atlantic following its successful Dec. 5 launch debut.
72 hours after B1050’s water landing and some painstaking preparation, the booster was towed to SpaceX’s dock space in Port Canaveral, where it spent just a brief few hours floating adjacent to drone ship Of Course I Still Love You and the rest of the company’s Florida fleet. Considerably less than twelve hours after arriving, technicians had already managed to lift the rocket out of the ocean and onto dry land, where another week or so was spent preparing Falcon 9 for transport.
Given the extent of the damage to the Block 5 booster’s interstage and the basic fact that SpaceX recovery technicians and engineers had never attempted anything quite like it before, it was fairly impressive that they took barely six hours to lift the booster out of the water, particularly considering that the rocket appeared to be filled with hundreds or even thousands of gallons of water. No visible damage was caused, although there was clearly some cause for extensive discussion and preparation per an unusually large and lengthy huddle of more than 30 employees prior to the beginning of the lift.

Once on land, B1050 had an unusual sling placed exactly where the Falcon 9 booster’s liquid oxygen (LOx) and kerosene (RP-1) propellant tanks were welded together, apparently a location that is particularly sensitive to off-nominal X-axis stress. To give context, imagine bending a cardboard tube or straw in half instead of trying to push its ends together – Falcon 9’s structure is quite similar in concept. Built primarily 5mm-thick sheets of lithium-aluminum alloy, Falcon 9’s propellant tanks are extremely thin and light while also being aggressively optimized for vertical (up and down) loading, i.e. the forces experienced while accelerating (and eventually decelerating) through the atmosphere during launch and landing.
As a result, SpaceX almost always pressurizes the first stage propellant tanks of Falcon 9 with nitrogen whenever boosters are horizontal without physical support at their bendy centers. In the case of B1050, SpaceX almost certainly concluded that using its waterlogged umbilical ports to inject nitrogen into its tanks was too much of a risk without knowing the precise condition of the piping and the tanks themselves, opting instead to go with a simple sling to prevent damage from unintended bending. Thankfully, B1050 appears to have made it through its dry land ordeal even better than the time it spent in the Atlantic, suffering no visible damage whatsoever.

Somewhere between December 14 and 15, the booster was at long last lifted onto SpaceX’s primary East Coast booster transporter and carefully drove the rocket to one of its 2-3 Cape Canaveral Air Force Station (CCAFS) refurbishment and storage hangars, avoiding detection by all but a few passersby. This could full well be the last we see (and even hear) of poor old Falcon 9 B1050, but there is still a decent chance that SpaceX hopes the entire rocket or major components can be easily salvaged.
Given the extreme care taken during the booster’s lift onto land and the week it spent having legs and grid fins removed, it can be definitively concluded that an effort will be made to save the entire vehicle (sans interstage). If it has managed to make it through the past two weeks largely unscathed, it may well become the first Falcon 9 to conduct a dedicated launch of multiple Starlink satellites sometime in the second half of 2019, at least according to CEO Elon Musk’s vague suggestion that it could fly on an “internal SpaceX mission”.
We may use it for an internal SpaceX mission

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.
