SpaceX rapidly turns around drone ship for sixth launch this month
SpaceX has rapidly turned around one of its two East Coast ‘autonomous spaceport drone ships’ and sent the vessel back to sea to support the sixth and final Falcon 9 launch planned this month.
SpaceX began the month with the successful launch of Transporter-4 – its fourth dedicated smallsat rideshare mission – on April 1st. Axiom-1 – the first all-private astronaut launch to the International Space Station – followed on April 8th. On the West Coast, another Falcon 9 rocket launched SpaceX’s second National Reconnaissance Office (NRO) spy satellite mission in two months on April 17th. Most recently, Falcon 9 booster B1060 tied SpaceX’s current 12-flight reusability record with the successful launch of a batch of Starlink satellites at 1:51 pm EDT on April 21st.
Drone ship Just Read The Instructions (JRTI) was tasked with supporting Falcon 9 booster recovery for Transporter-4 and Starlink 4-14. Now, less than a day after returning to Port Canaveral with booster B1060, the ship has been towed back to sea to support another Starlink launch and landing.
Due to almost two weeks of launch delays caused by Dragon recovery challenges, drone ship A Shortfall Of Gravitas (ASOG) – the second of two East Coast drone ships – has been stuck at sea while waiting to support NASA and SpaceX’s upcoming Crew-4 astronaut launch. To preserve plans for a late-April Starlink mission, SpaceX’s recovery team has needed to move about as fast as they ever have to allow JRTI to take ASOG’s place.
Following Starlink 4-14’s April 21st launch and landing, drone ship JRTI sailed into Port Canaveral around 2am EDT, April 24th. Within minutes of arriving at its usual berth, a dockside crane had swung over and begun installing a lifting cap on top of booster B1060. Less than four hours later, the booster was lifted off of JRTI’s deck and moved onto dry land, freeing up the space it occupied for any necessary inspections or repairs. The quick booster removal also gave SpaceX time to drive the drone ship’s robotic ‘Octagrabber’ recovery robot into a garage on its deck.
-->Just after 8pm EDT, less than 16 hours after JRTI reached its berth, support ship Bob towed the converted barge back out to sea. If Starlink 4-16 launches on time on April 29th, Just Read The Instructions will narrowly beat a three-year-old drone ship turnaround record (8d 6h) set by Of Course I Still Love You (OCISLY) in early 2019; recovering Falcon 9 booster B1062 just 8 days, 3 hours, and 42 minutes after Falcon 9 B1060 – and despite traveling ~1950 km instead of ~1850 km.
Ultimately, that distance is the main reason the current record has survived for so long. Short of building or modifying a new kind of recovery ship with a different type of hull, a flat-bottomed barge – towed or self-propelled – will never be able to traverse hundreds of miles of open ocean at high speeds.
Aside from breaking a potential drone ship turnaround record, Next Spaceflight reports that Starlink 4-16 will also almost certainly beat SpaceX’s current Falcon 9 booster turnaround record. Falcon 9 booster B1062 last launched Axiom-1 at 11:17 am EDT on April 8th. A 5:33 pm EDT, April 29th launch would translate to a turnaround time of 21 days and 6 hours, beating the current record of 27 days and 4 hours – set by B1060 in early 2021 – by more than a quarter.
If Crew-4 launches roughly on time, Starlink 4-14 will be SpaceX’s sixth launch in four weeks and 17th launch of 2022. If the company can sustain that pace over the remaining two-thirds of the year, it could feasibly launch more than 51 times in 2022.

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.
