SpaceX says crew spacecraft abort test still on track for 2019 launch
NASA recently invited members of the media to apply for access to SpaceX’s Crew Dragon in-flight abort (IFA) test and, as of December 5th, the company reaffirmed that the crucial test is still on track to launch just weeks from now.
In September, SpaceX CEO Elon Musk revealed that Crew Dragon’s IFA spacecraft and Falcon 9 was scheduled to arrive in Florida within a few weeks. Days later, NASA confirmed that the rocket and spacecraft arrived in Florida on October 3rd, sooner, in fact, than Musk had predicted. Over the next few weeks, SpaceX technicians and engineers effectively closed out Crew Dragon capsule C205, priming it for operations and installing its body panels.
On November 13th, about six weeks after arriving in Florida, SpaceX successfully tested Crew Dragon’s redesigned propellant plumbing and high-pressure gas systems by static firing its Draco thrusters and SuperDraco abort engines. The successful static fire test lasted around 9 seconds, mirroring the SuperDraco impulse and thruster inputs the spacecraft would need to demonstrate in an actual in-flight abort. Crew Dragon has four sets of two SuperDraco engines capable of producing a combined thrust of more than 130,000 lbs (570 kN), almost as much thrust as the original SpaceX Merlin 1D engines used on Falcon 9 in the early 2010s.
Meant to verify that SpaceX has successfully redesigned Crew Dragon after the spacecraft suffered a catastrophic explosion during a very similar static fire attempt, November 13th’s was followed by an exhaustive hardware inspection and data review, some of which is likely still ongoing. Although NASA’s media invite suggests that a given launch event could be just a month or so away, there is a ton of uncertainty when dealing with major launches of new hardware (like Crew Dragon), meaning delays are all but guaranteed.
During a pre-launch media briefing ahead of SpaceX’s CRS-19 Cargo Dragon launch, director of Dragon mission management Jessica Jensen answered a question about Crew Dragon’s IFA test, cautiously stating that SpaceX teams are “targeting [a] December” launch. During SpaceX’s December 5th CRS-19 launch webcast, Dragon Engineering Manager John Federspiel briefly brought up Crew Dragon, noting that SpaceX was completing “minor refurbishment” following its successful static fire.
-->Most notably, he stated the IFA test was “targeted for February of 2020”, while Crew Dragon’s subsequent ‘Demo-2’ astronaut launch debut was expected to follow no earlier than (NET) “the first quarter of [2020]”, implying either February or March.
As it happened, SpaceX and several media outlets almost immediately attempted to correct the record, instead suggesting that Crew Dragon’s abort test is still tracking towards a launch later this month. Given that a senior Dragon engineering manager was the one to unblinkingly – and without correction – state that IFA is NET February 2020, there’s a strong possibility that he is technically correct but was not supposed to publicize the mission’s delay. At the same time, SpaceX appears to be firm on its claim that IFA is still aiming for a late-December launch. Delays would be no surprise – Crew Dragon’s Demo-1 launch debut took an agonizing three months to go from heading to the launchpad for the first to actually lifting off, almost entirely due to minor technical bugs and NASA paperwork.
Regardless, with less than four weeks left in 2019, SpaceX has an exceptionally tight schedule ahead of it to meet that December 2019 IFA launch goal and will effectively have to static fire IFA’s Falcon 9 before the end of the week or crush Crew Dragon’s inaugural processing time by at least a factor of four to achieve it. As such, a delay in 2020 should be all but expected at this point. With any luck, however, Crew Dragon will successfully perform its in-flight abort within the next 4-8 weeks, leaving SpaceX in a good place to prepare for its inaugural astronaut launch a few months later.

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.
