SpaceX close to securing FAA license for Starship launch debut
A senior SpaceX director expects the United States Federal Aviation Administration (FAA) to grant a license for the first orbital launch of its next-generation Starship rocket in the “very near future.”
Speaking at the 2023 Space Mobility Conference, SpaceX Senior Director of National Security Space Solutions Gary Henry also indicated that Starship remains on track to launch as early as March 2023. Six weeks ago, CEO Elon Musk tweeted that SpaceX had “a real shot at [a] late February” Starship launch, adding that a “March launch attempt [appeared] highly likely.” February is now out of reach. But March may still be a viable target, according to Henry.

SpaceX has made significant progress towards Starship’s first orbital launch attempt in early 2023. On January 23rd, Ship 24 and Super Heavy Booster 7 were filled with around 4800 tons (~10.6M lbs) of propellant and completed Starship’s first full wet dress rehearsal, simulating a launch attempt up to the moment before engine ignition.
Two and a half weeks later, SpaceX attempted to ignite all 33 of Booster 7’s Raptor 2 engines. 31 engines ignited as planned, producing 3580 tons (7.9M lbf) of thrust – the most powerful static fire test in the history of rocketry. SpaceX and CEO Elon Musk have been relatively quiet about the test, merely noting that Starship may have still been able to reach orbit if it had lifted off with 31 of 33 engines.
By all appearances, the test was a spectacular success for SpaceX. 94% of Super Heavy’s Raptors ignited on the first attempted 33-engine test. The booster – standing as tall as an entire two-stage Falcon 9 rocket with a payload fairing – then safely drained its tanks. Booster 7 suffered no apparent damage, and SpaceX hasn’t removed or replaced any of its Raptor engines, potentially indicating that all 33 are healthy enough to stay on the booster for Starship’s first orbital launch attempt. That in itself is a major achievement.
On February 21st, SpaceX’s Gary Henry confirmed that Super Heavy Booster 7 and the launch pad that supported its record-breaking static fire test are in “good shape.” Counter to virtually all other large rockets in history, Starship’s first orbital launch pad has no water deluge system, flame trench, or thrust diverter to suppress or redirect the incredible amount of energy the rocket’s engines can produce. Despite that ommittance, the flat concrete directly below the pad appeared to survive almost eight million pounds of thrust and brutal heat with only minor spalling and damage.
The concrete adjacent to the orbital launch mount fared less well, but may eventually be replaced with the same high-temperature Fondag concrete that was added under the mount. If the launch mount and its surroundings are in “good shape” after experiencing about half of Starship’s full thrust, it’s possible that SpaceX will be ready to launch in the near future.
In the meantime, SpaceX is already installing a water deluge system that will eventually make its South Texas Starship launch site much more capable of withstanding the stress of Starship tests and launches. Installing that system and building a sufficiently massive water supply will take months, however, and would likely preclude a March launch attempt, indicating that SpaceX’s first orbital Starship launch attempt will happen without it.
SpaceX has, however, begun installing a final layer of shielding on Starbase’s orbital launch mount. That task will likely need to be completed before the launch attempt and could take a couple weeks.
The strongest sign that Starship’s first orbital launch attempt is imminent will be Ship 24’s return to the pad and reinstallation atop Booster 7, as well as SpaceX’s receipt of an FAA launch license. With testing mostly behind SpaceX, that license to launch may now be the biggest source of uncertainty for Starship’s orbital-class debut. If, as Gary Henry and spaceflight journalist Christian Davenport have indicated, there are no major hurdles standing in the way of that FAA license, Starship could be ready to launch in a matter of weeks.

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.
