NASA chooses SpaceX to launch a self-propelled space station to the Moon
Days after SpaceX won a NASA contract to launch a galaxy-mapping space telescope, the space agency has selected Falcon Heavy to launch a small space station to the Moon some four years from now.
Loosely known as Gateway, NASA and a few of its ‘centers’ have been floating the concept for years – partially on its merits as a potential platform to dip toes into crewed deep spaceflight and explore the Moon but mostly as a way to give the bloated Space Launch System (SLS) rocket and Orion spacecraft a destination for destination’s sake. Weighed down by an extremely inefficient European Service Module (ESM), NASA couldn’t use Orion to replicate its famous Apollo Moon missions if it wanted to.
Lacking the necessary performance to safely place Orion and its astronauts into the Low Lunar Orbit (LLO) optimal for a new round of crewed Moon landings, Orion/ESM on its own is limited to higher, more exotic lunar orbits with less immediate value. As a result, NASA’s Lunar Gateway will be delivered to a “near-rectilinear halo orbit” (NRHO) where it will orbit the Moon’s poles at altitudes between 3,000 and 70,000 kilometers (1,900-43,000 mi).
Bureaucratic machinations and sunk-cost fallacies aside, any space station orbiting the Moon would be an impressive technical feat and an undoubtedly exciting venture. NASA says SpaceX’s combined Power and Propulsion Element and Habitation and Logistics Outpost (PPE/HALO) Falcon Heavy launch contract will ultimately cost approximately $332 million, although that figure includes vague “other mission-related costs” that could have nothing to do with SpaceX and be separate from the company’s actual launch services.
Less than a year ago, NASA awarded SpaceX $117 million to launch Psyche – a scientific spacecraft with an overall cost similar to PPE/HALO – on Falcon Heavy.
Possibly contributing to the unusually high cost is the fact that Falcon Heavy will need a stretched payload SpaceX is already working on for the US military to launch the massive PPE/HALO stack, which will stand around 15 meters (50 ft) tall and weigh ~14 metric tons (~31,000 lb) when combined. While heavy, that payload mass is somewhat mundane for SpaceX, which has launched 17 16-metric-ton batches of Starlink satellites since November 2019.
What isn’t mundane for SpaceX is launching such a large payload beyond Starlink’s low Earth orbit (LEO) destination. According to a virtual presentation recently given by a Northrop Grumman HALO engineer, PPE/HALO will be delivered to an elliptical orbit similar but lower than the geostationary transfer orbit (GTO; ~250 km by ~36,000 km) traditional for commercial communications satellites.
That low target orbit thankfully means that PPE/HALO wont be SpaceX’s first fully expendable Falcon Heavy launch. Depending on how far below GTO NASA is willing to accept, SpaceX could potentially launch PPE/HALO and attempt to land all three first boosters at sea, a configuration that leaves enough performance to send 10 metric tons to GTO. If SpaceX proposed Falcon Heavy with an expendable center core, the rocket could feasibly launch PPE/HALO beyond GTO, cutting the amount of time it would take for PPE to slowly spiral out to the Moon with its electric thrusters.
NASA says the launch is scheduled no earlier than (NET) May 2024 – decidedly optimistic given that the space agency has yet to even award HALO’s production contract.

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.
