SpaceX to launch “next-generation satellite-servicing vehicle” for Northrop Grumman
Northrop Grumman subsidiary SpaceLogistics has selected SpaceX to launch its first Mission Robotic Vehicle (MRV) – better described as the company’s “next-generation satellite-servicing” spacecraft.
As far as SpaceX’s Falcon 9 rocket is concerned, MRV-1 is just another geostationary satellite for it to deliver to a transfer orbit around 35,800 kilometers (~22,200 mi) above Earth’s surface as early as “spring 2024.” As of now, SpaceX Falcon rockets have launched more than 35 satellites to geostationary transfer orbits (GTO) and have at least 18 more geostationary launch contracts on its manifest – 19 including MRV-1. MRV-1 is no ordinary geostationary communications satellite, however.
MRV isn’t a communications satellite at all, in fact. Instead, designed to be the second generation of Northrop Grumman’s satellite life-extension spacecraft, MRV aims to build upon the successes of the company’s first two Mission Extension Vehicles (MEVs). The first (MEV-1) became the first spacecraft in history to dock with another spacecraft in geostationary orbit (GEO) in February 2020. The second, MEV-2, successfully launched and docked with a different geostationary communications satellite in 2021. Both MEVs did exactly what they were supposed to, effectively giving their host satellites – Intelsat 10-02 and 901, both more than 15 years old – at least five more years of operational life.
While SpaceLogistics’ accomplishments are thus extremely impressive, the general MEV concept and parts of its execution have some flaws. First, the ‘service’ offered appears to be extremely expensive, costing Intelsat – the first and only customer, thus far – at least $13 million per year for the five years MEV-1 will be servicing Intelsat-901. No other MEV contracts have been confirmed, which is not a major surprise. Assuming zero upfront costs for prospective customers, $65 million for an extra five years of operations represents a substantial fraction of the price of some simpler replacement satellites, many of which are now designed to operate for at least 15 years.
Put simply, at the secretive price point SpaceLogistics is offering, MEVs are a mostly ambiguous financial proposition for the geostationary satellite communications industry, which tends to operate on razor-thin margins. Though SpaceLogistics hasn’t said as much, MRV seems to be a response to the issue of affordability. Instead of building one large, expensive MEV that can only service a single GEO satellite, MRV aims to operate more like a multipurpose space tug.
To complement MRV, Northrop Grumman is also developing Mission Extension Pods (MEPs) – smaller spacecraft designed to still add at least 5-6 years of life to an aging GEO satellite. MRVs – each about 3 tons (~7000 lb) will theoretically be able to carry several MEPs (400 kg/900 lb apiece) into geostationary orbit and install the pods on several different satellites. Additionally, it appears that SpaceLogistics will sell the pods outright, presumably precluding the need for expensive recurring service contracts like those Intelsat signed for MEV life extension.
According to Northrop Grumman, MEPs will actually propel themselves into GEO before being recaptured and installed by MRV – requiring two rendezvous and docking maneuvers per satellite instead of one. It’s entirely unclear why that added complexity is preferable over the obvious alternative, in which MRV would launch with a number of MEPs, carry them to GEO, and install them when needed.
Nonetheless, assuming Northrop Grumman plans to offer MEP life-extension pods for less than it charged for MEVs, it’s not hard to imagine the service becoming a no-brainer for communications providers with satellites that are close to running out of propellant. If the cost of several extra years of operational life is lower than the cost of an equivalent fraction of the lifespan of a new replacement satellite, it’s difficult to imagine how satellite operators could afford not to take advantage of life extension.
Northrop Grumman says it’s already sold one MEP – to launch with MRV-1 on Falcon 9 – to Australian telecom provider Optus and has a full manifest for MEPs “through mid-2026.”

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.
