SpaceX Crew Dragon spacecraft splashes down with NASA, ESA astronauts
Update: A SpaceX Crew Dragon spacecraft carrying four NASA and ESA astronauts has safely splashed down off the coast of Florida, wrapping up an exceptionally busy four weeks of Dragon launch, docking, undocking, and recovery operations.
For the second time in ten days, a SpaceX Crew Dragon spacecraft has undocked from the International Space Station (ISS) and is on its way back to Earth.
This time around, four professional Crew-3 astronauts from NASA and ESA boarded Crew Dragon and departed the station after almost six months in orbit, handing off command and control of the US segment to Crew-4. After grappling with a 12-day delay, SpaceX successfully launched Crew-4 to the ISS on April 27th and the astronauts arrived at the station later the same day. Crew-4 was only able to launch after a separate crew of exclusively private astronauts known as Axiom-1 finally departed the ISS on April 24th.
Falcon 9 launched Axiom-1 and Crew Dragon on April 8th on what was initially supposed to be a 10-12 day mission in orbit. As a result of extensive weather-related recovery delays, Axiom-1 instead splashed down on April 25th. Those collective delays ultimately gave Crew-3 around two extra weeks in orbit before Crew-4 was able to take over, freeing them up to return to Earth.
NASA astronauts Raja Chari, Tom Marshburn, Kayla Barron, and German ESA astronaut Matthias Maurer began preparing for their departure in earnest about half a day prior on May 4th and boarded Dragon a few hours before undocking. Now verging on routine, Crew Dragon undocked from the ISS without issue at 1:20 am EDT on May 5th, kicking off a roughly 24-hour return to Earth.
Crew-3’s Dragon will perform a final deorbit burn shortly before midnight on May 6th and, if all goes well, the spacecraft’s reusable capsule will splash down off the coast of Florida a bit before 1am EDT. It will be Crew Dragon’s second astronaut reentry and splashdown in ten days after Axiom-1 completed the same process on April 25th.
-->In just four weeks, SpaceX will have launched Ax-1, docked Ax-1 with the ISS, undocked and recovered Ax-1; launched Crew-4, docked Crew-4 with the ISS; and undocked and recovered Crew-3 – a series of eight major Dragon operations involving three of the company’s fleet of four reusable orbital spacecraft. Given the numerous delays suffered by all three missions as a result of their close proximity, it would be hardly surprising if NASA and SpaceX explicitly try to avoid that level of cadence for future ISS-related Dragon operations.
Nonetheless, SpaceX and NASA are already in the late stages of preparing an uncrewed variant of Dragon 2 for the company’s 25th ISS cargo delivery. CRS-25 is scheduled to launch as early as June 7th and will be SpaceX’s third Dragon launch and third mission to the ISS in less than two months. Later this year, SpaceX Dragons are scheduled to support CRS-26 in September, Axiom-2 as early as Q3 2022, Crew-5 in October, and Polaris Dawn – a free-flyer mission – in Q4 2022.

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.
