SpaceX releases video of world’s most powerful rocket ready for liftoff
Just a few days after its first-ever rollout to Launch Complex 39A, SpaceX has published its official photos of the historic moment, capturing Falcon Heavy poised and ready at the launch pad that could host its inaugural flight as soon as January 15th.
These photos offer the first glimpses of the complete, integrated Falcon Heavy, now with Elon Musk’s Tesla Roadster payload and second stage attached to the massive rocket. While SpaceX has not yet revealed specific details regarding the Roadster’s actual destination, it can be assumed that Falcon Heavy and its second stage will attempt to place it into an extremely stabled orbit around the sun, with one side close to the orbit of Mars. In this configuration, it’s unlikely that there will be any possibility of in-space photo opportunities with the Tesla and Mars. Musk has confirmed that its orbit will be extremely stable, and Roadster will likely remain in its final space journey for hundreds of millions or even billions of years.
With more than 5 million pounds of thrust at liftoff—equal to approximately eighteen 747 aircraft at full power—Falcon Heavy will be the most powerful operational rocket in the world by a factor of two. https://t.co/NneqPRPr46 pic.twitter.com/oswCUreG6i

While Falcon Heavy’s inaugural launch will apparently see the vehicle operating at only 92% thrust, this performance would still easily catapult the rocket above all other operational launches vehicles by nearly a factor of two.
At a total of 5 million pounds of thrust (22.8 kN), the rocket would be able to lift a fully-fueled 747 passenger jet into low Earth orbit (LEO) in an expendable configuration. Its performance with full recovery of its three first stages is not public, on the other hand, but SpaceX will nevertheless be attempting to recover all first stages alongside the inaugural launch. Approximately 30 seconds before Falcon 9’s usual main engine cut-off (MECO) point, Falcon Heavy’s twin side boosters will separate from the center core (essentially a complete Falcon 9) with the help of some form of mechanical actuators designed to gently push those boosters away from the center.
Quite frankly, the intense aerodynamic forces present at the point of side booster separation mean that it is entirely possible that they may not survive, and could even be drawn back in to impact the center core, an eventuality that would likely bring the mission to a premature end. Typically, rockets with a similar triple booster first stage (Titan IV, Delta IV Heavy) have used relatively powerful separation rockets to more sternly force the side boosters away from the main stage, generally with great success. However, the sort of single-use separation motors would run counter to SpaceX’s primary pursuit of completely reusable rockets.
Risks aside, if all goes well, the side cores will separate and return to the land-based Landing Zone-1 (LZ-1) at Cape Canaveral Air Force Station, and will likely land simultaneously and offer nearby Floridans a double dose of sonic booms as they slow down from speeds well above Mach 3. Meanwhile, the center stage will throttle up and continue on as if it were a Falcon 9. The core stage will finally separate from the second stage and Roadster payload and power back down to Earth to attempt a recovery aboard the drone ship Of Course I Still Love You. Given SpaceX’s previous history of rather exceptional live coverage of both their Falcon 9 launches and landings, fans can expect a truly stunning tour-de-force of a show if the launch goes as planned.
Even then, a failure would still be quite a spectacle and is undeniably a real possibility for any new form or iteration of a rocket. However, it is rather implausible that SpaceX would choose to take unreasonable risks with one of its invaluable launch pads, particularly LC-39A – tasked with supporting SpaceX’s upcoming Commercial Crew demonstration missions no earlier than August 2018. Musk’s hyperbole aside, he can be taken at his word when he in the past commented that the launch would be a spectacle one way or another. The massive vehicle’s first static fire attempt, the final step ahead of launch, is to occur no earlier than January 6th, 2018.
Follow along on Instagram as Teslarati’s launch photographer and correspondent Tom Cross provides behind-the-scenes live coverage of both the launch of Zuma (NET January 5) and the final operations ahead of Falcon Heavy’s first launch.

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.
