SpaceX ready for second ever reused Falcon 9 launch on June 19
SpaceX’s Falcon 9 “1029” is nearly ready to conduct its second commercial launch later this weekend after today’s successful static fire at Launch Complex 39A. Static fire was initially planned for June 13th but was delayed to the 14th and then the 15th, with the launch date also being delayed by two days to June 19th. This small delay is likely a result of launch pad readiness procedures taking a bit longer than intended.
Now scheduled with a window of 2-5 p.m. EST on June 19th, a successful launch will mark the second successful reuse of a Falcon 9 first stage and thus the second ever reuse of an orbital-class rocket. This particular first stage, 1029, is coincidentally symbolic in the sense that it launched SpaceX’s first mission after the Amos-6 failure last year, when a complex series of events led to a massive explosion that destroyed Falcon 9, the Amos-6 payload, and severely damaged the site it was to launch from. Elon Musk deemed it “the most difficult and complex failure” SpaceX had ever faced. It was all the more surprising that the company returned to flight just over four months later, in an industry in which failures of the same scale can result in launch vehicle groundings of multiple years (the Space Shuttle, Orbital ATK’s Antares).

The best possible demonstration of a launch company’s confidence in their ability to spring back from a trying failure may well be a willingness to reuse the actual launch vehicle that marked their return to flight. And that is exactly what SpaceX is about to attempt with the second launch of 1029, which flawlessly orbited Iridum’s first set of ten NEXT satellites in the company’s return to flight after Amos-6.
Falcon 9 1029 will be tasked with placing the satellite in a geostationary transfer orbit, meaning that the satellite itself will use its own bi-propellant thrusters to reach its final geostationary orbit above Earth. With a mass estimated around 4000 kilograms, 1029 will very likely be able to attempt a recovery by landing on SpaceX’s West coast Autonomous Spaceport Drone Ship (ASDS), known as Of Course I Still Love You (OCISLY). There have also been reports of the mythical Optimus Prime robot conducting tests aboard OCISLY yesterday, hinting that this recovery may be the first time that the robot will be allowed to attempt to secure the recovered first stage after landing on the drone ship.

-->An automated method of securing recovered stages after landing has the potential to progress SpaceX’s goal of rapid reusability, and BulgariaSat-1 will mark the beginning of a schedule that has SpaceX attempting to launch Falcon 9 three times in 14 days, a truly impressive accomplishment even if delays stretch it out to 20+ days.

BulgariaSat-1 has lately been called Bulgaria’s first true satellite, but it is really the country’s second satellite. Manufactured and assembled by the Palo Alto, California-based Space Systems Loral (SSL), it will offer much broader coverage of the Europe and Balkans regions and provide high quality satellite television and telecommunications services in a bid to expand Bulsatcom’s market.
Much like cars are often built off of the same chassis, BulgariaSat-1 is based upon a communications satellite bus (SL-1300) that has flown successfully dozens of times and currently has dozens of active variants in geostationary orbits. BulgariaSat-1 will be the sixth SL-1300 derived satellite that SpaceX themselves have launched, and the company has four other SL-1300 satellite scheduled for launch in 2017 and 2018.

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.
