SpaceX’s Crew Dragon preps for debut as race to return astronauts to US craft nears final stages
After spending two weeks testing in a specialized NASA-run facility, SpaceX’s first flightworthy Crew Dragon spacecraft was shipped from Ohio to Florida, where it will now spend a number of months preparing for its first (uncrewed) launch into Earth orbit.
Known as Demonstration Mission 1 (DM-1), this critical milestone must be passed before the capsule will be certified to carry NASA astronauts to the International Space Station (ISS) sometime in 2019. While DM-1 will not sport a human crew, the spacecraft is nevertheless expected to demonstrate all life and mission-critical components, ranging from Crew Dragon’s complex array of avionics and ground/orbital communications equipment to craft’s ability to safely return passengers to Earth with a soft ocean landing.
SpaceX’s Crew Dragon spacecraft has been in the serious hardware development phase for approximately five years, although the concept itself dates back about as early as its Cargo Dragon predecessor – 2005 to 2006, publicly. Over the course of roughly two weeks of testing at NASA’s Plum Brook Station, Crew Dragon was likely subjected to a suite of environmental conditions the spacecraft will need to routinely survive to make it through initial launch and successfully operate under the rigors of microgravity and thermal vacuum conditions.

-->Given the DM-1 capsule and trunk’s fairly quick jaunt at the huge Plum Brook vacuum chamber and equally quick arrival in Florida, those test results were likely quite favorable. Still, a major amount of work lies ahead before the first full Crew Dragon is ready for its launch atop Falcon 9. Most significantly, the craft’s trunk did not follow its fellow capsule to Florida, but rather returned to SpaceX’s Hawthorne, CA factory to be outfitted with critical flight hardware, particularly radiators and solar arrays. Once that outfit is complete, the module will also be shipped to Florida before being integrated with the DM-1 Crew Dragon capsule.
Of note, the DM-1 capsule has been constructed from the start to support a plan to use the vehicle in an in-flight abort test meant to ensure that the craft can wrest its passengers from harm’s way even at the most intense point of launch, where aerodynamic pressures are at their peak. In order to properly support both the DM-1 orbital mission and the in-flight abort test to follow, the capsule has been outfitted with a fair amount (hundreds of pounds) of hardware that will be unique to the pathfinder spacecraft. This understandably adds its own complexity to the already intense program’s first orbital mission, although it will hopefully not translate into additional delays.

SpaceX competitor’s crewed spacecraft and rocket take shape
It’s worth noting that SpaceX is effectively operating at a distinct – albeit partially self-wrought – financial handicap when compared with Boeing’s Starliner spacecraft program, one of two vehicles funded by NASA to accomplish the same task of safely and reliably transporting astronauts to and from the ISS.
“NASA awarded firm-fixed-price contracts in 2014 to Boeing and Space Exploration Technologies Corporation (SpaceX) [of] up to $4.2 billion [for Boeing] and $2.6 billion [for SpaceX] for the development of crew transportation systems.” (GAO-18-476)

In other words, Boeing requested and received a full 60% more than SpaceX to – quite literally – accomplish an identical task. Alongside the storied and brutally expensive history of crewed American spaceflight, both contracts are an absolute steal for two modernized, crew-capable spacecraft, but a 60% premium is a 60% premium. Foreseeable but slight cost overruns caused, among other things, by additional contractual requirements from NASA have followed a similar trend, roughly proportional to each company’s slice of the original $6.8b Commercial Crew contract.
-->“As of April 2018, NASA requirement changes had increased the value of contract line item 001 for Boeing by approximately $191 million and for SpaceX by approximately $91 million.” (GAO-18-476)
Still, Boeing’s progress towards its own DM-1 and DM-2 demo flights and a pad-abort test are impressive, although it very likely is more of a demonstration of a different approach to public communications than of any actual step up on SpaceX. In the last few weeks, Boeing has released a number of photos showing off the progress made building its own Starliner capsules and service modules (trunks), three of which are currently in varied states of assembly and integration in the company’s Florida-based facility. Additionally, United Launch Alliance CEO Tory Bruno has shared off-and-on updates and photos of the launch contractor’s own progress assembling the rockets that will launch Boeing’s spacecraft.

Regardless, a huge amount of work lies ahead before both Boeing and SpaceX’s crewed spacecraft are able to conduct their first uncrewed and crewed launches into orbit. Now very outdated, NASA has stated several times recently that the presently available targets of NET August 31 will likely be updated later this month, pushing DM-1 debuts into NET Q4 2018 and the first commercial crewed demo missions to 2019.
Stay tuned, as the Block 5 Falcon 9 tasked with launching SpaceX’s own DM-1 Crew Dragon will likely be the next of a recent flood of finished rockets to leave the company’s Hawthorne factory, where it will head to McGregor, Texas to complete acceptance wet dress rehearsals and static fire tests before shipping to SpaceX’s Pad 39A in Florida.

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.
