SpaceX’s next step towards airplane-like Falcon 9 reusability expected in 2018
Speaking at an impromptu IAC 2018 talk, Vice President of Build and Flight Reliability Hans Koenigsmann confirmed earlier this month that SpaceX is aiming to conduct its first triple reuse of a Falcon 9 booster before the year is out.
While not entirely confident on the specific mission it would end up flying on, Koenigsmann floated the company’s next Vandenberg, CA launch – Spaceflight Industry’s SSO-A rideshare – as a prime candidate, tentatively targeting November 19th.
As of November 19th, only two Falcon 9 Block 5 boosters will be candidates for a third reuse – B1046 and B1048. Falcon 9 B1048 launched for the second time just days ago, placing Earth observation satellite SAOCOM 1A in orbit before performing the first return-to-launch-site (RTLS) recovery on the West Coast, also marking the debut of SpaceX’s long-dormant LZ-4 landing zone. Aside from playing a role in one of the most spectacular launch-related light shows ever created, B1048 is noteworthy for being SpaceX’s second-fastest Falcon 9 booster turnaround, taking just 74 days to go from its first launch and landing to its second operational use.
While B1046 – launched first on May 11th and again on August 7th – will have had more than three months of potential refurbishment by SSO-A’s Nov. 19 launch target, both of its two launches involved relatively high-energy profiles with heavy payloads, resulting in higher (and thus more damaging) heating during reentry. B1048, on the other hand, has launched a heavy set of 10 Iridium NEXT satellites into a low-energy orbit and then launched the much lighter SAOCOM 1A spacecraft into an equally low orbit, translating to much more forgiving reentries and thus much easier refurbishment.
Later at IAC 2018, Hans spoke in more detail about the leading challenges facing SpaceX in this relatively mature stage of reusable rocketry optimization. Most notably, he seemed to imply that the most difficult aspect of refurbishing Falcon 9 boosters was damage caused to its nine Merlin 1D engines while taking the brunt of Falcon 9’s reentry inertia, not hugely surprising given the awkward geometry and sheer force behind a booster traveling more than 2000 meters per second.

It’s possible that SpaceX will set B1046 up as the pathfinder for all future reusability milestones, including the 3rd, 4th, and 5th booster flights and beyond. However, B1048 may well be in better condition, is already directly stationed at its refurbishment facility, and will have another relatively low-energy launch ahead of it if assigned to SSO-A. Critically, flying for the third time on SSO-A – as few as 43 days after its second orbital launch – will require B1048 to break SpaceX’s record for faster Falcon 9 booster turnaround by more than 50%, despite the fact that it would have two full operational missions under its belt.
It may sound more mundane than other crowning SpaceX achievements, particularly with the focus on numbers that might seem arbitrary and unimportant at first glance, but it’s actually difficult to overstate just how important the third reuse of a Falcon 9 booster is, particularly if that pathfinder happens to break refurbishment records at the same time.
SpaceX’s ultimate goal is to build and launch rockets with airplane-like reusability and reliability, eventually flying boosters and other components upwards of 100-1000 times each, and the jump from two flights per core to three will be the best evidence yet that the company is making rapid progress in that direction.

Tesla Model Y and Model 3 top world’s best-selling EV rankings in September
The two vehicles’ feat was highlighted recently by CEO Elon Musk in a post on X.
The Tesla Model Y and Model 3 are still the best-selling electric vehicles in the world in September, a remarkable achievement given that both EVs are premium models that typically command higher prices than their competitors.
The two vehicles’ feat was highlighted recently by CEO Elon Musk in a post on X.
Still best-selling
As observed by tech watcher @XFreeze, the Model Y and Model 3 were the world’s #1 and #2 best-selling electric vehicles in the world in September 2025. Interestingly enough, the list includes both battery electric vehicles and plug-in hybrid electric cars.
During the month, Tesla was able to sell 140,904 Model Y crossovers and 67,374 Model 3 sedans across the globe. This is quite impressive considering that the Model Y and Model 3 have been around for several years now, and they are still premium-priced.
Staying power
The Model Y and Model 3’s stellar staying power may be due to a variety of factors, including the vehicles’ bang-for-the-buck nature. The Model 3, for example, is quite a bit closer to the price of a Toyota Camry or Honda Civic, but its amenities are closer to those of the BMW 3 Series. The same is true for the Model Y.
Despite their relatively mainstream price, the Model 3 and Model Y offer a ton of tech features that are only available in Teslas. These include Full Self-Driving, which is steadily becoming a huge selling point in territories where it is available, and the company’s vast suite of tech-centric convenience features. The fact that the Model 3 and Model Y are among the safest vehicles in their respective classes doesn’t hurt either.
Tesla has lost its Model Y Program Manager, he announced on LinkedIn, marking the second major departure from the company today.
Emmanuel Lamacchia has been in the role for 4 years and 7 months, responsible for the rollout of the all-electric crossover in several markets.
The Model Y became the best-selling vehicle in the world for two years under Lamacchia’s watch, making this a huge loss for the company. However, it seems the decision was made under Lamacchia’s own initiative.
He confirmed his decision on LinkedIn:
“After 8 incredible years, I’m moving on from Tesla.
What a journey it’s been… from leading NPI for Model 3 and Model Y variants to becoming the Vehicle Program Manager for Model Y, the best-selling car in the world!
Leading the All-New Model Y launch was the highlight: converting all 4 factories across 3 continents in just 2 weeks. Something that had never been done before in the auto industry.
To the teams who made this possible: you should be incredibly proud. This achievement belongs to you: the engineers, designers, buyers, and associates in Fremont, Shanghai, Berlin, and Austin who turned an impossible timeline into reality.
Grateful to the leaders who trusted me with programs that stretched my capabilities and to the cross-functional partners who showed me that great solutions come from collaboration, not hierarchy.
Tesla taught me how to move fast without breaking things and how to scale from prototypes to millions of units.
Excited for what’s next. More to share soon.”
It marks the second major program loss for Tesla today, as it also bid farewell to Cybertruck and Model 3 Program Manager Siddhant Awasthi, who said he left voluntarily in “one of the hardest decisions of his life.”
Lamacchia was at Tesla for just a shade under eight years, and previously worked for Rolls-Royce for roughly the same amount of time.
After the loss of both Lamacchia and Awasthi today, Tesla has lost a handful of key executives in 2025, including:
- David Imai, Director of Design
- David Lau, VP of Software Engineering
- Mark Westfall, Head of Mechanical Engineering
- Prashant Menon, Regional Director in India
- Vineet Mehta, Head of Battery Architecture
- Omead Afshar, VP/Head of Sales and Manufacturing in North America
- Milan Kovac, Head of Optimus Team
- Jenna Ferrua, Director of HR
- Troy Jones, VP of Sales, Service, and Delivery
- Pete Bannon, VP of Hardware Engineering
- Piero Landolfi, Director of Service

Tesla prepares to expand Giga Texas with new Optimus production plant
Drone operator Joe Tegtmeyer recognized Tesla construction crews performing ground leveling and clearing efforts at the plant earlier today.
Tesla is preparing to expand Gigafactory Texas once again with a brand new facility that will house the eventual manufacturing efforts for Optimus, its humanoid robot.
It is already building some units on a Pilot line at the Fremont Factory in Northern California, but Tesla is planning to build the vast majority of its Optimus project at Gigafactory Texas.
Tesla Optimus gets its latest job, and it’s not in the company’s factories
It will build one million units per year in Fremont, but CEO Elon Musk said the company would build 10 million units every year in Texas at a new building at Giga Texas.
Musk said:
“I think there could be tens of billions of Optimus robots out there. Um, now obviously it’s very important we pay close attention to safety here. Then a 10 million unit uh per year production line here the I don’t know where we’re going to put the 100 million unit production line. on Mars. Maybe on Mars, I don’t know.”
Evidently, Tesla is ready to begin thinking about the production efforts of Optimus beyond a theoretical standpoint and is starting to prepare for the construction of the manufacturing plant on Giga Texas property.
Drone operator Joe Tegtmeyer recognized Tesla construction crews performing ground leveling and clearing efforts at the plant earlier today:
Giga Texas News!
A brand-new, stand-alone factory is starting construction! This follows the Shareholders meeting & info that a 10-million-per-year @Tesla_Optimus production facility “on the Giga Texas campus” will be built & enter into production in 2027!
Here are some… pic.twitter.com/7ig5DohfOt
— Joe Tegtmeyer 🚀 🤠🛸😎 (@JoeTegtmeyer) November 10, 2025
Production is still slated for 2027, at least at Gigafactory Texas. As previously mentioned, the company is building some units in Fremont for the time being, at least until subsequent versions of the Optimus project advance.
Tesla has done a great job of advancing Optimus forward, but it also has truly grand expectations for the project.
Musk said it could potentially be the biggest product in the history of the planet, as it will revolutionize the way humans perform tasks, probably eliminating monotonous tasks from everyday life.
