SpaceX rocket test-fired for first Starlink launch since in-flight engine failure
Just a month after an automatic launch abort sequence and subsequent in-flight engine failure, the SpaceX Falcon 9 is ready to return to flight. SpaceX’s sixth Starlink V1.0 and seventh overall launch of 60 Starlink satellites – initially expected on April 16th later delayed to April 23rd – will mark the triumphant return of a flight-proven booster.
Early on Thursday, April 16th – a week ahead of the scheduled launch attempt – the flight-proven B1051 Falcon 9 booster fully stacked with the integrated payload of 60 flat-stacked Starlink satellites, rolled out to Launch Complex 39-A at Kennedy Space Center. Just over twenty-four hours later on Friday, April 17th, the rocket and payload were raised into the vertical launching position. At noon on Friday, SpaceX teams conducted a wet dress rehearsal fully fueling the first stage booster with propellant – rocket grade kerosene (RP-1) and liquid oxygen (LOX) – before successfully conducting a full-duration, pre-launch ignition of all nine Merlin 1D engines while holding the rocket in place – called a static fire.
Shortly after the test completion, SpaceX confirmed the targeted Thursday, April 23rd launch attempt scheduled for 3:16 pm EDT from LC-39A via the company’s Twitter account. Along with the launch date, SpaceX confirmed that the upcoming Starlink-6 mission (seventh overall) will be the fourth attempted launch and recovery of booster B1051. This booster previously supported launches from three different launchpads in Florida and California. Perhaps most notably, it supported the successful first uncrewed demonstration mission of the Crew Dragon capsule in March of 2019.
SpaceX also confirmed that the protective nosecone encapsulating the satellite payload, called the payload fairing, is also recovered and reused flight-proven hardware. To date, SpaceX has reused fairing halves twice. Both instances have been conducted on internal Starlink missions, one in November 2019 and the most recent on March 18th’s Starlink-5 mission. Both featured fairing halves that were recovered after landing softly in the water of the Atlantic ocean. Ultimately, only the fairing halves of the most recent March 18th Starlink-5 mission were successfully recovered. The recovery attempt during November’s mission was called off due to rough seas.
According to SpaceX, April 23rd’s upcoming Starlink-6 mission will feature fairing halves recovered from the AMOS-17 mission launched in August of 2019. As previously covered by Teslarati, the mission resulted in a fairing half caught in a large net mounted atop one of the company’s fairing recovery vessels, GO Ms. Tree. The other half was scooped up after a gentle water landing. Starlink-6 will be the first time that a fairing half caught in a net is re-used in conjunction with a half recovered from the water. If the fairing halves perform nominally, as expected, it will help SpaceX to push the envelope of flight-proven hardware reuse even further.
Closely mirroring the Starlink-5 mission, SpaceX will once again launch from LC-39A and utilize a slightly altered mission profile. This will allow the Falcon 9’s second stage to deliver the 60 flat-stack satellites to an elliptical, rather than circular, orbit intended to reduce stress during booster re-entry and landing. Although used with previous missions, this particular mission profile has yet to result in a successful booster recovery.
-->If successful, Starlink-6 will be the first time a booster lands on the autonomous spaceport drone ship “Of Course I Still Love You” since this boosters last landing in January 2020 following the successful Starlink-4 mission. As of Sunday morning, April 19th, “Of Course I Still Love You” departed Port Canaveral to travel to the recovery zone some 629km downrange ahead of Thursday’s launch attempt. The crew recovery vessel, GO Quest, followed shortly thereafter. The two fairing recovery vessels GO Ms. Tree and GO Ms. Chief are expected to leave port early in the week as the ships are built for speed and will reach the destination much quicker.

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.
