SpaceX’s Falcon 9 and Heavy manifest grows lopsided as launches align for Q4
For a variety of reasons both clear or otherwise, a significant number of SpaceX’s Falcon 9 and Falcon Heavy launches initially scheduled near the beginning or middle of the second half of 2018 are all slipping right into October, November, and December.
While communications satellite Telstar 18V’s two-week slip to NET September 8 and SAOCOM-1A’s own several-week tumble to October 7th appear to have their own respective and discernible reasons, namely some sort of range or payload issue (Telstar) and difficulties with the Falcon 9 rocket (SAOCOM), it’s much harder to know why multiple other payloads have slipped into late 2018.
Although the multiple slips and slides of several payloads and much of SpaceX’s H2 2018 launch manifest may be hard to parse alongside the year’s milestone first half, at least two reliable launch manifest sources (SpaceflightNow and one other) more or less independently corroborate the apparent realignment. Explanations, however, are far harder to find – to be expected in the business of space launch. Still, multiple launch delays can be traced to either payload or rocket issues.

Payload-side delays aplenty but rocket-slips, too
Iridium CEO Matt Desch, for example, noted that his company’s Iridium NEXT-8 launch of the constellation’s final 10 satellites is slipping from its original launch date target because of delays preparing the satellites for launch, rather than any issue with SpaceX rocket availability. While not official, the Falcon 9 launch of communications satellite Es’hail-2 has also rapidly jumped from the end of August or early September into Q4 2018 (likely NET October or November), hinting heavily at payload processing delays or technical issues with the complex satellite, as multi-month rocket-side delays would likely preclude interim September and October launches.
Still trying to nail the date down (satellite completion is gating, not rocket availability), but definitely won't be in September.

Meanwhile, at least two of those prospective Q4 2018 SpaceX launches happen to be rideshare-dedicated, meaning that the payload consists of dozens of smaller satellites manifested and organized by a middleman company or agency. These two launches are Spaceflight’s SSO-A launch (~70 satellites) – currently NET November 2018 – and the US Air Force-led STP-2 mission, designed primarily to help SpaceX certify Falcon Heavy for Air Force launches while also placing roughly two dozen smaller satellites into orbit. STP-2 was delayed for multiple years as SpaceX gradually paced towards Falcon Heavy’s first real launch debut (February 2018), but launch delays (currently NET November 30 2018, probably 2019) will likely be caused by some combination of rocket, payload, and pad delays as SpaceX readies for what is essentially the second debut of much different Falcon Heavy.
While likely less a payload-side delay than a mountain-of-tedious-paperwork-and-bureaucracy delay, SpaceX’s NET November 2018 inaugural (uncrewed) demonstration launch of Crew Dragon, NASA scheduling documents published alongside an August 27 Advisory Council presentation suggest that the spacecraft will be ready for launch as early as September, whereas independent sources and visual observations have confirmed that the new Falcon 9 Block 5 booster (B1051) is either near the end or fully done with its McGregor, Texas acceptance testing. One certainly cannot blame SpaceX or NASA for caution at this stage, but the consequently uncertain launch debut of Crew Dragon almost certainly precludes any Falcon Heavy launches from Pad 39A in the interim, including STP-2’s theoretical NET November 30 launch date, which is literally inside Crew Dragon’s “November 2018” launch target.

On the other hand, several recent delays of SpaceX’s imminent (-ish) launch of Argentinian Earth observation satellite SAOCOM-1A have been suggested by several employees of the country’s CONAE space agency to be rocket-related, as they understand that the satellite itself is effectively ready to head to orbit at any time. It has yet to be officially confirmed, but it’s understood that Falcon 9 B1048 – previously flown on the launch of Iridium-7 – is being refurbished for SAOCOM-1A, potentially contributing to launch delays as SpaceX cautiously works through the inaugural reuses of some of its very first serial Falcon 9 Block 5 boosters.
-->Time will soon tell, as launching the roughly 8 to 10 launches tentatively remaining on SpaceX’s 2018 manifest will require extensive reuse of Block 5 boosters if multiple slips into 2019 are to be prevented. Regardless, best of luck to SpaceX’s technicians and engineers as they beat back rocket demons, grapple with uncooperative satellite payloads, and navigate the winding paths of Department of Defense and NASA rocket launch certifications.

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.
