SpaceX docks two Dragons to the space station for the first time
For the first time, SpaceX has successfully docked two Dragons to the International Space Station (ISS) at the same time.
Carrying roughly three metric tons (~6600 lb) of cargo, SpaceX’s first upgraded Cargo Dragon aced its inaugural orbital flight and docking attempt on the first try, safely latching itself to the space station around 1:45 pm EST (UTC-5) on Monday, December 7th.
For the second time, Roscosmos cosmonaut Sergey Kud-Sverchkov thankfully managed to pick up some of the slack from the inexplicably tiny handful of NASA photos published from two historic Dragon arrivals, capturing both Crew-1 and CRS-21 in spectacular detail.
There are two Dragons on the @Space_Station at once. The #Dragon2 cargo spacecraft (an uncrewed ‘twin’ of the Crew Dragon) arrived yesterday and delivered scientific equipment, food supplies, etc.

The ground velocity is tremendous: about 8 km/s, while the relative velocity of the multiton vehicle during touchdown is only 15 cm/s – it went almost unnoticed. pic.twitter.com/dqZ63qn8MX— Sergey Kud-Sverchkov (@KudSverchkov) December 8, 2020
Admittedly, the single official photo of CRS-21 thus far published by NASA offers the first screenshot-free view of SpaceX’s Crew-1 Crew Dragon and CRS-21 Cargo Dragon in the same frame, succinctly capturing the historic milestone.


During NASA’s docking webcast, both retractable Cargo and Crew Dragon nosecones were also visible simultaneously, serving as a reminder that Cargo Dragon 2 is essentially a tweaked version of Crew Dragon. According to NASA, the space agency has officially signed contracts for at least nine Cargo Dragon 2 launches total, meaning that – barring additional contracts or an extension of the ISS lifespan – the final uncrewed Dragon flight could be CRS-29 in 2023 or 2024.
SpaceX itself uploaded a timelapse of Cargo Dragon 2’s first ISS docking taken from the spacecraft’s own camera not long after the milestone, offering some of the best live views of an ISS cargo or crew arrival in recent memory.
Ultimately, according to SpaceX officials, Crew-1 – launched on November 15th – kicked off what the company believes will be at least a year of a continuous Dragon presence on orbit, also meaning that all future Dragon launches (beginning with CRS-21) will see two Dragons simultaneously operating in orbit for at least a month or two. In the two-decade history of the International Space Station, only Russia’s national space agency has managed such a feat, serving as the sole provider of crew transport from 2011 to 2020 while simultaneously performing routine cargo launches.


In 2021 alone, SpaceX has plans for at least five – and maybe six – Dragon launches, including the first astronaut launch to use a flight-proven spacecraft and booster and the first fully private tourist mission to orbit. Combined with Starlink, the back-to-back operational debuts of Crew Dragon and Cargo Dragon 2 arguably make SpaceX the world-leader in the production and operation of satellites and reusable spacecraft.

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.
