SpaceX has successfully launched three Falcon 9 rockets less than 34 hours apart, leaving the company only one mission shy of CEO Elon Musk’s ambitious target of 60 launches in 2022.

The period was almost even more intense, with two launches briefly scheduled minutes apart and all three set to launch in the space of 10-11 hours. But the more conservative sequencing SpaceX ultimately settled on still produced impressive results and allowed the company to break its own world record for the fastest time to complete three launches of the same rocket. In June 2022, SpaceX managed three similar launches – a Starlink mission, a scientific Earth observation satellite, and a commercial communications satellite – in 36 hours and 18 minutes.

Six months later, SpaceX has shaved more than two hours off of its own feat with the successful launches of another Earth observation satellite, a pair of commercial communications satellites, and 54 Starlink satellites in 33 hours and 46 minutes.

SpaceX’s latest hat trick began on December 16th with a Falcon 9 launch of the joint US-French Surface Water and Ocean Topography (SWOT) mission out of Vandenberg Space Force Base (VSFB), California. Delayed from December 12th and 15th, the launch was nonetheless a perfect success, placing the 2.2-ton (~4850 lb) radar satellite into a low Earth orbit that will allow it to precisely analyze virtually every inch of exposed water on Earth. That unprecedented capability should make it easier for scientists to study and understand Earth’s water cycle, as well as humanity’s substantial impact on those processes.

A little over 11 hours later, a second Falcon 9 rocket lifted off from SpaceX’s Cape Canaveral Space Force Station LC-40 pad carrying the first two Boeing-built O3b mPOWER satellites for satcom provider SES. Once again, SpaceX’s workhorse rocket did its job perfectly, even managing to exceed its contracted parameters according to SES CEO Steve Collar. Falcon 9’s better-than-expected performance will reduce the amount of time and propellant each 1.7-ton (~3750 lb) mPOWER satellite requires to reach its operational orbit, potentially ensuring a quicker path to revenue generation and longer useful lifespans.

SpaceX is on contract to launch all 11 initial mPOWER satellites. The next nine satellites will head to orbit sometime in 2023 and 2024 as Boeing completes them.

Finally, less than a day later after O3b mPOWER 1&2, a third Falcon 9 rocket lifted off from SpaceX’s NASA Kennedy Space Center LC-39A pad (just a few miles north of LC-40) with what could be the last full batch of “Group 4” Starlink V1.5 satellites. SpaceX’s first-generation Starlink constellation is comprised of five groups of satellites operating in distinct orbital ‘shells,’ and the company’s December 18th launch of Starlink 4-37 will leave SpaceX just 14 satellites away from fully finishing the second of two shells of 1584 satellites. All told, Starlink 4-37 was SpaceX’s 65th operational Starlink launch since November 2019 and the company likely has just ~20 launches to go to complete its first satellite constellation – already the largest in history by an order of magnitude.

All three launches were completed in less than a day and a half. Further emphasizing the breadth of SpaceX’s expertise, each Falcon 9 booster successfully landed after supporting their respective orbital launch, ensuring that those boosters will all be able to support more launches in the near future. In fact, Starlink 4-37 was the 15th mission for its Falcon 9 booster, B1058, breaking SpaceX’s internal reuse record and pushing the technology’s envelope. It remains to be seen if the company will push beyond 15 flights. In June 2022 interviews with Aviation Week, SpaceX executives stated that Falcon boosters would be retired after 15 flights – a big change from past indications that there was nothing preventing each booster from launching 100+ times with regular maintenance.

Starlink 4-37 was also SpaceX’s 59th successful orbital launch of 2022. In March, CEO Elon Musk raised an earlier annual target of 52 launches to 60 launches. At the time, 60 launches in one year was almost inconceivable. Set in 1980, the all-time record for a family of rockets (the Russian R-7) is 61 successful launches in one calendar year.

But against all odds, SpaceX has relentlessly executed week after week and sustained an average of one launch every six days for more than 12 months. Multiple sources currently indicate that SpaceX has two more Falcon 9 launches scheduled this year: another Starlink mission as early as December 28th and a mission carrying the Israeli EROS-C3 Earth imaging satellite on December 29th. SpaceX’s Falcon rocket family thus has a chance to tie the all-time record of 61 R-7 family launches, which was backed by the entire Soviet Union at the peak of its national launch cadence.

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).

Published

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.”

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.
