SpaceX aces first Moon launch with a reused rocket

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 Semi catches fire in California: what we know

Published

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.

The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.

There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.

However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.

The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.

The truck’s driver said that the Semi caught fire, but he did not have an explanation.

An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year.

Tesla’s ‘Emergency Drive Away’ function gets its first use in the real world

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.

A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.

“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.

Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.

Tesla constitutes the following situations as reasonable justifications for activating the feature:

  • You face an immediate threat to your life or personal safety.
  • You must leave the area immediately.
  • Exiting the vehicle is unsafe.
  • Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.

After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper

Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.

Published

By

Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.

Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.

The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.

Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.

The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”

That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.

The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.

Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
