SpaceX set for third Falcon 9 reuse in October, swaps a 2018 launch with Arianespace
Satellite operator and manufacturer SES has decided to juggle launches between SpaceX and Arianespace, a French launch provider.
Made for a number of reasons related to the economics of satellite operation and launch date uncertainty, SES has chosen to have SpaceX launch the heavier SES-12 satellite in Q1 of 2018, and Arianespace will now launch SES-14 “early Q1” of 2018. SES has experienced difficulties with some of its operational satellites that have led to decreased revenue, and the goal with the launch swap is to guarantee that SES will have an operational, revenue-generating satellite in place a few weeks sooner than they might have had if relying on SpaceX’s uncertain launch date.
The relationship between launch providers and launch customers has long been a complex legal process, but the upside with this flip is that thorough contracts anticipated this possibility and allowed SES flexibility in the eventuality that they need to expedite launches or change launch vehicles. It is intriguing that SES would adopt the necessary risks associated with switching launch vehicles months before launch to maybe gain an extra few weeks of additional revenue, but SES has admittedly had a difficult year for satellite reliability.
SES-12, the satellite SpaceX is now contracted to launch, weighs about 1000 kg more than SES-14 and will be pushing the limits of Falcon 9 recovery at ~5300 kg. Both satellites are completely electric, meaning they utilize efficient ion propulsion, which lowers the amount of fuel needed and allows satellite manufacturers to include far more revenue-generating payload on a satellite. The downside of ion propulsion is that it produces far less thrust than the average chemical rocket, meaning that all-electric satellites take months to reach their operational orbits, compared to a handful of weeks with chemical propulsion.

While admittedly heavy, SpaceX will almost certainly attempt booster recovery following the launch of SES-12, unless SES requests that the launch be expendable. An expendable launch could potentially benefit SES by expediting the satellite’s trip to geostationary orbit, thus providing the company more revenue. However, this would have likely been acknowledged in SES’ press release. As such, we can look forward to a toasty booster recovery, likely sporting titanium grid fins to cope with the intense heating the core will experience.
Nearer term, SES-11 is pressing ahead for an early-October launch this year, and will mark SpaceX’s third commercial re-flight of a recovered Falcon 9 first stage. SES has long been one of the most avid and committed supporters of SpaceX, and the two companies built a relationship and signed contracts by 2011, before SpaceX’s Falcon 9 had even conducted its inaugural flight. SES has been and likely will continue to be a crucial example of the success of reuse.
-->Meanwhile, SpaceX is looking to conduct its next launch on September 7th, and static fire attempt is expected Thursday, August 31 at their LC-39A launch pad in Florida. This mission will launch the USAF’s secretive X-37B spaceplane into a low Earth orbit, and while there will likely be no views of the payload on the livestream, that likely means that SpaceX will focus heavily on the booster recovery. NROL-76 was the last launch that featured this focus, and it produced some incredible views of the first stage as it returned to Earth.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
