SpaceX’s Falcon 9 rocket has become the first in history to launch a spacecraft to the Moon using reused hardware.

That spacecraft: a domestically-developed South Korean ‘pathfinder’ and Moon orbiter known as KPLO or Danuri. Weighing about 678 kilograms (~1500 lb) and roughly the size of a small car, KPLO will be the South Korea’s first mission beyond Earth orbit and, if successful, could make it the 8th country in history to reach orbit around another planetary body. According to officials from South Korea’s Aerospace Research Institute (KARI), the Moon orbiter is just the tip of the country’s ambitions, which it hopes will include missions to the lunar surface, asteroids, and even Mars in the “near future.”

South Korea chose SpaceX’s Falcon 9 rocket to launch KPLO by 2020 in late 2017, barely six months after the company’s first commercial reuse of the rocket’s recoverable first stage (booster). Five years later, the launch of a new Falcon booster is a rare and noteworthy event, and the company has simultaneously matured payload fairing recovery and reuse into a routine and common process.

The KPLO mission is now the first time in spaceflight history that a reused rocket has launched a spacecraft to the Moon. SpaceX chose to launch KPLO on the sixth flight of Falcon 9 booster B1052, and was also able to convince KARI to opt for a reused payload fairing, saving the institute money while also demonstrating just how widely accepted even Falcon fairing reuse has become. KPLO’s fairing halves flew for the fourth time as part of the Moon launch and will be recovered for future use after they splash down in the Atlantic Ocean.

Falcon booster B1052 likely has an even longer career ahead of it, as SpaceX has flown three other boosters 13 times and reportedly intends to launch each booster at least 15 times.

Safely on its way into deep space, KPLO’s efficient “ballistic lunar trajectory” or BLT will take it on a circuitous, multi-month journey around an Earth-Sun Lagrange point that should eventually reach the right position to enter lunar orbit in December 2022. While Falcon 9 is fully capable of sending KPLO directly to the Moon on a trans-lunar injection (TLI) trajectory, KARI decided late in development to switch to a BLT trajectory, saving around 165 meters per second of delta V that can instead be used to significantly extend the orbiter’s useful longevity around the Moon.

KPLO’s defining purpose is to image the Moon with several cameras and scout for a landing site for a future South Korean Moon lander, but it will also undoubtedly contribute to planetary science and help improve humanity’s understanding of its closest neighbor. One instrument – ShadowCam – supplied by NASA could prove essential for characterizing the quantity of water ice hidden in the Moon’s permanently shadowed regions. Water ice could eventually be mined and turned into rocket propellant depots on the lunar surface.

Tesla’s breakthroughs with its 4680 battery cell program mark a significant milestone for the electric vehicle maker. This was, at least, as per Elon Musk in a recent post on social media platform X.

Tesla confirmed in its Q4 and FY 2025 update letter that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process.

Why dry-electrode matters

In a post on X, Elon Musk stated that making the dry-electrode process work at scale was “incredibly difficult,” calling it a major achievement for Tesla’s engineering, production, and supply chain teams, as well as its partner suppliers. He also shared his praise for the Tesla team for overcoming such a difficult task. 

“Making the dry electrode process work at scale, which is a major breakthrough in lithium battery production technology, was incredibly difficult. Congratulations to the @Tesla engineering, production and supply chain teams and our strategic partner suppliers for this excellent achievement!” Musk wrote in his post.

Tesla’s official X account expanded on Musk’s remarks, stating that dry-electrode manufacturing “cuts cost, energy use & factory complexity while dramatically increasing scalability.” Bonne Eggleston, Tesla’s Vice President of 4680 batteries, also stated that “Getting dry electrode technology to scale is just the beginning.”

Tesla’s 4680 battery program

Tesla first introduced the dry-electrode concept at Battery Day in 2020, positioning it as a way to eliminate solvent-based electrode drying, shrink factory footprints, and lower capital expenditures. While Tesla has produced 4680 cells for some time, the dry cathode portion of the process proved far more difficult to industrialize than expected.

Together with its confirmation that it is producing 4680 cells in Austin with both electrodes manufactured using the dry process, Tesla has also stated that it has begun producing Model Y vehicles with 4680 battery packs. As per Tesla, this strategy was adopted as a safety layer against trade barriers and tariff risks. 

“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,” Tesla wrote in its Q4 and FY 2025 update letter.

Even Tesla China seems to have caught the Optimus V3 fever, with the electric vehicle maker teasing the impending arrival of the humanoid robot on its official Weibo account. 

As per Tesla China, Optimus V3 is “about to be unveiled.”

Tesla China hypes up Optimus V3

Tesla China noted on its Weibo post that Optimus V3 is redesigned from first principles and is capable of learning new tasks by observing human behavior. The company has stated that it is targeting annual production capacity of up to one million humanoid robots once manufacturing scales.

During the Q4 and FY 2025 earnings call, CEO Elon Musk stated that Tesla will wind down Model S and Model X production to free up factory space for the pilot production line of Optimus V3.

Musk later noted that Giga Texas should have a significantly larger Optimus line, though that will produce Optimus V4. He also made it a point to set expectations with Optimus’ production ramp, stating that the “normal S curve of manufacturing ramp will be longer for Optimus.”

Tesla China’s potential role

Tesla’s decision to announce the Optimus update on Weibo highlights the importance of the humanoid robot in the company’s global operations. Giga Shanghai is already Tesla’s largest manufacturing hub by volume, and Musk has repeatedly described China’s manufacturers as Tesla’s most legitimate competitors.

While Tesla has not confirmed where Optimus V3 will be produced or deployed first, the scale and efficiency of Gigafactory Shanghai make it a plausible candidate for future humanoid robot manufacturing or in-factory deployment. Musk has also suggested that Optimus could become available for public purchase as early as 2027, as noted in a CNEV Post report.

“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,” Musk said during the earnings call.

Tesla director pay lawsuit sees lawyer fees slashed by $100 million

The ruling leaves the case’s underlying settlement intact while significantly reducing what the plaintiffs’ attorneys will receive.

The Delaware Supreme Court has cut more than $100 million from a legal fee award tied to a shareholder lawsuit challenging compensation paid to Tesla directors between 2017 and 2020. 

The ruling leaves the case’s underlying settlement intact while significantly reducing what the plaintiffs’ attorneys will receive.

Delaware Supreme Court trims legal fees

As noted in a Bloomberg Law report, the case targeted pay granted to Tesla directors, including CEO Elon Musk, Oracle founder Larry Ellison, Kimbal Musk, and Rupert Murdoch. The Delaware Chancery Court had awarded $176 million to the plaintiffs. Tesla’s board must also return stock options and forego years worth of pay. 

As per Chief Justice Collins J. Seitz Jr. in an opinion for the Delaware Supreme Court’s full five-member panel, however, the decision of the Delaware Chancery Court to award $176 million to a pension fund’s law firm “erred by including in its financial benefit analysis the intrinsic value” of options being returned by Tesla’s board.

The justices then reduced the fee award from $176 million to $70.9 million. “As we measure it, $71 million reflects a reasonable fee for counsel’s efforts and does not result in a windfall,” Chief Justice Seitz wrote.

Other settlement terms still intact

The Supreme Court upheld the settlement itself, which requires Tesla’s board to return stock and options valued at up to $735 million and to forgo three years of additional compensation worth about $184 million. 

Tesla argued during oral arguments that a fee award closer to $70 million would be appropriate. Interestingly enough, back in October, Justice Karen L. Valihura noted that the $176 award was $60 million more than the Delaware judiciary’s budget from the previous year. This was quite interesting as the case was “settled midstream.”

The lawsuit was brought by a pension fund on behalf of Tesla shareholders and focused exclusively on director pay during the 2017–2020 period. The case is separate from other high-profile compensation disputes involving Elon Musk.
