Massive storm on Mars downs NASA’s Opportunity Rover after 14 years on the red planet
NASA recently held a press conference about the current status of the Opportunity Rover (or Oppy, as it is fondly called), which is weathering a massive storm covering a quarter of the Red Planet’s surface. According to NASA, communication with Opportunity remains down as of date, though the space agency is optimistic that the 14-year-old rover can still make it through the storm.
The massive storm currently affecting Mars covers 15.8 million square miles (41 million square kilometers), which is roughly the size of North America and Russia combined. The intensity of the storm has effectively blocked the sunlight on Mars’ surface, preventing Opportunity to charge its batteries. The rover is currently near the center of the storm, inside the Red Planet’s Perseverance Valley. NASA is under the assumption that Opportunity’s batteries have dipped below 24 volts, causing the machine to enter low power fault mode. In this state, all of Opportunity’s subsystems except its mission clock are turned off. During NASA’s press conference, John Callas, Opportunity’s project manager, stated that the rover’s present state invokes concern.
“The analogy I would use right now is it’s like you have a loved one in a coma in the hospital. The doctors are telling you that you’ve just got to give it time and she’ll wake up, all the vital signs are good, so it’s just waiting it out — but you know, if it’s your 97-year-old grandmother you’re going to be very concerned. And we are. By no means are we out of the woods here,” he said.
Opportunity has been on the Red Planet for close to 15 years, far more than the duration of its original 90-day mission. As of January 2018, the rover has managed to cover a distance of 45.09 kilometers (28.02 miles), studying Mars’ terrain and laying the foundations for missions to come. Opportunity was sent to the Red Planet with its sister rover, Spirit. While both machines were able to last far beyond their initial 90-day mission, Spirit ultimately fell silent in 2010, six years into its exploration of the Martian landscape.
Overall, it would be truly sad to lose Opportunity after such a long and storied life, but the near future will be filled with many new robotic Martians striving to uncover the Red Planet’s mysteries. After all, Opportunity, as well as Spirit and the larger, nuclear-powered Curiosity rover (which is also experiencing reduced solar energy due to the massive storm), have all but laid the foundations for further and more ambitious missions on the Red Planet. Plans are already underway to develop and launch Mars 2020, a rover based on Curiosity, and ExoMars, a rover from Europe — both of which would be tasked to find signs of life. Mars Insight, a robotic lander designed to study the interior of the Red Planet, has also been launched last May and is expected to land sometime in November.
Despite the challenge facing Opportunity right now, however, Jim Watzin, the director of NASA’s Mars Exploration Program, stated that NASA is still hoping the nearly 15-year-old rover will somehow survive.
“We’re all pulling for Opportunity. As you know, it’s been a remarkably resilient rover, lasting 15 years — well beyond its original design life of just 90 days. Its longevity has taught us much about operating on the surface of Mars. But regardless of how this turns out, this little rover has proven to be an invaluable investment that has greatly increased our ability to explore the Red Planet,” he said.

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.
