SpaceX private astronaut launch debut to reuse Crew-1 Dragon spacecraft
A former NASA astronaut now employed by Axiom Space says that SpaceX’s private astronaut launch debut will reuse the same Crew Dragon spacecraft currently supporting NASA’s Crew-1 mission in orbit.
Currently just a few weeks into a planned six-month stint in orbit, potentially marking the longest uninterrupted flight of an American spacecraft ever, Crew Dragon capsule C207 and an expendable trunk section arrived at the International Space Station (ISS) on November 16th. Known as Crew-1, the mission represents SpaceX and NASA’s commercial operational astronaut launch debut, carrying four astronauts to the ISS.
Crucially, the mission has been an almost flawless success so far and Falcon 9 has now completed four Crew Dragon launches without issue. On the Dragon side of things, the Crew-1 spacecraft performed a bit less perfectly than those tasked with flying Demo-1 and Demo-2, but SpaceX handled the minor issues that arose with the professionalism and composure of a team far more familiar with human spaceflight.
Early success aside, there is still some definite uncertainty ahead of Crew Dragon. While several Russian spacecraft have decades of experience spending at least several months at a time in orbit, a crewed US spacecraft has never spent more than 84 days in orbit. SpaceX itself actually beat out NASA to secure the second-place record with Crew Dragon’s 63-day Demo-2 astronaut launch debut, completed with a successful reentry and splashdown on August 2nd.
However, Crew-1 is expected to more than double that previous US record and almost triple SpaceX’s own second-place record, spending roughly 180 days (six months, give or take) in orbit. Barring an unprecedented space station or spacecraft emergency, Crew Dragon C207 will undock from ISS, reenter Earth’s atmosphere, and splashdown in the Gulf of Mexico or the Atlantic Ocean sometime in May 2021. Of course, as the first recoverable US spacecraft to spend anywhere close to that long in orbit, the Crew-1 Crew Dragon will be closely monitored to ensure the safety and reliability of its intricate reentry and recovery systems after some six months exposed to the extremes of space.
Still, success is by far the likeliest outcome. When Crew Dragon C207 splashes down, its four astronaut passengers will be carefully extricated and the inspection and refurbishment process will begin almost immediately thereafter. Crew-1 will technically be the second Crew Dragon spacecraft to be refurbished after an orbital spaceflight, following Demo-2 capsule C206’s inaugural Dragon 2 reuse perhaps just a month or two prior.
The Demo-2 Crew Dragon capsule is currently scheduled to fly a second time as early as March 31st, 2021 on SpaceX’s Crew-2 mission, ferrying another four astronauts to the ISS. If successful, Crew-2 will represent the first commercial astronaut launch ever to reuse both an orbital-class rocket booster and an orbital spacecraft, and the NASA-overseen process of refurbishment and re-flight will thus pave the way for future flight-proven astronaut launches. That includes private company Axiom Space’s first private AX-1 astronaut launch, which is currently scheduled to launch as early as Q4 2021.
AX-1 will be captained by former NASA astronaut Mike Lopez-Algeria and carry three other private astronauts, including Israeli multimillionaire Eytan Stibbe. SpaceX will thus be tasked with launching Israel’s second astronaut ever after Ilan Ramon was killed when a heat shield design flaw caused NASA Space Shuttle Columbia to break up during reentry in 2003.

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.
