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 confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
