SpaceX Falcon 9 doubleheader still on track after fiery ULA launch abort
As previously reported by Teslarati, SpaceX announced intentions to launch two Falcon 9 missions from two Florida launchpads on Sunday, August 30th. However, the ambitious goal was left in limbo.
The record-breaking doubleheader was believed to hinge upon the Saturday morning launch of a United Launch Alliance (ULA) Delta IV Heavy rocket with a classified spy satellite. However, that is apparently no longer the case.
Instead of launching on time, ULA’s infrequently-flown heavy-lift rocket was hit by 72 hours of delays to rectify minor pad hardware bugs. Around 2 am EDT (UTC-4) on August 29th, Delta IV Heavy made it just seconds away from liftoff before the rocket’s autonomous flight computer detected an anomaly with pad hardware and aborted the launch. As a result, the three cores’ three Aerojet Rocketdyne RS-68A engines were forced to shut down after ignition – an uncommon Delta IV launch abort scenario that has historically required at least a week of work to recycle for another launch attempt.
ULA ultimately determined that it was not possible to recycle the countdown for another attempt although enough time remained in the launch window to do so. The launch vehicle was safed and a scrub was announced.
In a statement provided by ULA confirmed that the early shutdown was “due to an unexpected condition during the terminal count at approximately three seconds before liftoff.” ULA also confirmed that “the required recycle time prior to the next launch attempt is seven days minimum.”
ULA has to fly before SpaceX, right?
With a minimum of seven days required to recycle the ULA Delta IV Heavy for another launch attempt, it was unclear what that meant for the fate of the SpaceX SAOCOM-1B mission.

It was previously understood that in order for SpaceX to launch the SAOCOM-1B mission from nearby Space Launch Complex-40 (SLC-40), the ULA Delta IV Heavy would have to successfully launch first. The southern polar launch trajectory of the SAOCOM-1B’s mission is one that hasn’t been flown from Cape Canaveral, FL in nearly six decades. This particular flightpath includes launch hazard zones that inch ever so close to the launchpad of the Delta IV Heavy, which is currently still on its launchpad stacked with a classified payload for the U.S. government.
It was assumed that the Falcon 9 would suffer the same minimum delay of seven days, if not longer. However, on Saturday afternoon, August 29 a SpaceX media representative confirmed that the company was still targeting the historic double header launches on Sunday, August 30.
Double the launches, double the recoveries
If SpaceX can pull it off, Sunday is set to be a stellar day for Falcon 9 launches and landings. The SAOCOM-1B mission will feature a Return To Launch Site (RTLS) landing attempt of the expended Falcon 9 booster while the Starlink Falcon 9 booster is expected to land aboard the autonomous droneship “Of Course I Still Love You” currently stationed off the coast of South Carolina.
In an unusual move, SpaceX split up the fairing catching vessels. Initially, both vessels left Port Canaveral and headed south to a catch zone located between The Bahamas and Cuba in an attempt to catch both fairing halves of the SAOCOM-1B mission. Then, GO Ms.Tree did an about-turn and met up with the booster recovery vessels off the coast of South Carolina.
At the time of publishing, the two Sunday Falcon 9 launches are expected to occur just nine hours apart. The Starlink V1.0-L11 mission is slated to occur at 10:12am ET (1412 UTC) from Launch Complex 39-A at Kennedy Space Center while the SAOCOM-1B mission is set to launch at 7:18pm ET (2318 UTC) from SLC-40 at Cape Canaveral Air Force Station. As usual, SpaceX will host official launch webcasts live, typically beginning around 15 minutes before liftoff.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->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-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

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.
