SpaceX’s Japanese Moon lander launch back on the calendar after indefinite delay
Update: After indefinitely delaying ispace’s first Moon lander launch on November 30th to fix unspecified issues with its Falcon 9 rocket, multiple sources indicate that SpaceX has put the mission back on its calendar.
Barring additional issues, the private HAKUTO-R Moon lander is now scheduled to lift off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad no earlier than (NET) 3:04 am EST (08:04 UTC) on Wednesday, December 7th. The mission’s quick return after just a few days of rework is a good sign that the issue that forced SpaceX to stand down was relatively minor. Simultaneously, SpaceX is moving ahead with plans to launch its first mission for OneWeb – a low Earth orbit satellite Internet provider competing directly with Starlink – less than ten hours prior, at 5:37 pm EST (22:37 UTC) on December 6th.
SpaceX support ship Doug departed Florida’s Port Canaveral on the afternoon of December 4th, likely en route to recover Falcon 9’s payload fairing after its first OneWeb launch. If SpaceX is, in fact, working towards a December 7th launch of HAKUTO-R, twin support ship Bob will likely also head to sea within the next 24 hours.
SpaceX has delayed the launch of Japanese startup ispace’s first Moon lander, HAKUTO-R, from Wednesday to Thursday, December 1st “to allow for additional pre-flight checkouts.”
The mission will be the third Moon launch from US soil in less than four months after SpaceX’s successful launch of the South Korean Pathfinder Lunar Orbiter (KPLO) in August and the debut of NASA’s Space Launch System (SLS) rocket earlier this month. Perhaps more importantly, ispace has the opportunity to become the first company in history to successfully land a privately-developed spacecraft on the Moon, a milestone that would arguably mark the start of a new era of lunar exploration.

ispace’s first HAKUTO-R Moon lander is expected to weigh approximately 1050 kilograms (~2300 lb) at liftoff and is designed to land up to 30 kilograms (~66 lb) of cargo on the lunar surface. The lander is made by several commercial partners: ispace has provided most of its design and structures, but Europe’s ArianeGroup supplied all of HAKUTO-R’s engines, plumbing, and propulsion hardware and was responsible for most of the final assembly process.
Because of ArianeGroup’s involvement, it’s likely that HAKUTO-R shares direct heritage with the European Service Module currently powering NASA’s Orion spacecraft on its first mission to the Moon. It also arguably makes the mission more of a collaboration between Europe and Japan than an exclusively Japanese mission, though HAKUTO-R will still technically be Japan’s first private mission to the Moon.
If successful, it could also become the first privately-funded Moon landing in history. But HAKUTO-R can’t claim to be the first private Moon landing attempt, a title held by Israeli company SpaceIL’s ill-fated Beresheet Moon lander. Launched by SpaceX as a rideshare passenger sitting on top of an Indonesian communications satellite, Beresheet propelled itself all the way from geostationary transfer orbit to lunar orbit over the course of about six weeks. Just a minute or so before touchdown, a manual command inadvertently shut down the spacecraft’s propulsion, causing it to impact the surface of the Moon at ~500 kilometers per hour (310 mph) – less than 8% away from a soft landing.
In September 2019, just five months later, India’s first nationally developed Moon lander got even closer to a successful landing, losing control at a velocity of just 210 km/h (~130 mph) and an altitude of 330 meters (1080 ft). Since the Soviet Union’s 1976 Luna-26 mission, only China’s national space agency (CNSA) has successfully landed on the Moon, completing three landings between 2013 and 2020. The last successful Western Moon landing (Apollo 17; also the last crewed Moon landing) occurred in 1972.
ispace’s ultimate goal is to help facilitate the creation of infrastructure capable of supporting a permanent population of 1000 people on the Moon by 2040. The Japanese startup has privately raised $210 million since it was founded in 2010. In 2022, it won a $73M NASA contract to develop a much larger SERIES-2 vehicle capable of sending either “500 kilograms to the [lunar] surface or as much as 2000 kilograms to lunar orbit.” SERIES-2 will be developed out of ispace’s US branch instead of its Japanese headquarters.
HAKUTO-R will carry seven payloads:
- A solid-state battery for ispace corporate partner NGK SPARK PLUG CO
- A Moon rover (Rashid) for the United Arab Emirates space agency
- JAXA’s transformable lunar robot
- A Canadian Space Agency flight computer prototype
- A camera system built by Canda’s Canadensys
- A panel engraved with the names of HAKUTO’s crowdfunding supporters
- A music disc containing Japanese rock band Sakanaction’s song “SORATO”
In addition to HAKUTO-R, SpaceX’s Falcon 9 rocket will simultaneously launch the NASA Jet Propulsion Laboratory’s (JPL) Lunar Flashflight ice surveyor as a rideshare payload. After launch, Lunar Flashlight will attempt to enter an elliptical lunar orbit and use an infrared laser to (invisibly) illuminate the surface of craters that have been in shadow for millions of years. The way the surface reflects that laser light will allow the spacecraft to prospect for water ice deposits that could one day be mined and converted into rocket propellant.
Tune in below around 3:20 am EST (08:25 UTC) on Thursday, December 1st to watch SpaceX launch Japan’s first privately-developed Moon lander.

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.
