SpaceX Crew Dragon In-Flight Abort test gets its first firm launch date
The day after questions arose around the targeted launch date of SpaceX’s Crew Dragon In-Flight Abort test (IFA), SpaceX and NASA have officially set the date for the spacecraft’s next major flight test.
On Friday, December 6th, a NASA Commercial Crew Program blog post confirmed a NET date of Saturday, January 4th, 2020 for the IFA test. The IFA test is one of the most notable final steps to be completed by the Crew Dragon capsule prior to supporting crewed astronaut flight to the International Space Station in 2020 as a part of NASA’s Commercial Crew Program.
Following an apparent incorrect statement made during SpaceX’s CRS-19 webcast that identified a February 2020 target date of the IFA test, SpaceX provided re-assurance that teams were very much still working toward a NET December launch date.
A January 4th date falls just short of SpaceX’s December goal but it still comes as little surprise. In addition to this week’s CRS-19 launch, SpaceX aims to support two more launches prior to year’s end – an internal mission to launch 60 more Starlink satellites and the launch of the JCSAT 18/Kacific 1 communications satellite for customers SKY Perfect JSAT Corp. of Japan and Kacific Broadband Satellites of Singapore. While completing four Falcon 9 launches and landings in a period of less than four weeks is certainly possible for SpaceX, it was rather ambitious, especially given that Crew Dragon’s abort test is almost certainly the company’s preeminent priority.
The targeted January launch date now encroaches into the first quarter of 2020, which SpaceX has adamantly stated is also the goal for Crew Dragon’s first NASA astronaut launch, known as Demo-2. With the IFA test now NET January 4th, it will be a major challenge for NASA and SpaceX to turn around and prepare Crew Dragon and Falcon 9 for Demo-2 just 4-12 weeks later. Of note, Boeing is preparing its own Starliner spacecraft for an uncrewed launch test NET December 20th and has also claimed that it wants to launch a crewed flight test (CFT, akin to SpaceX Demo-2) as early as February 2020, same as SpaceX.
It’s extremely unlikely that NASA will be able to preserve both of those schedules given the Commercial Crew Program’s fixed workforce and the vast quantity of paperwork it must complete before the agency can give the go-ahead for SpaceX and Boeing astronaut launches.
Unsurprisingly, the blog post confirmed that the IFA test would launch from Kennedy Space Center Launch Complex 39A (LC-39A). Pad 39A is the same facility that previously supported Crew Dragon’s March 2019 Demo-1 launch debut and is the only pad SpaceX intends to launch Crew Dragon from.
Interestingly, Pad 39A is also an active construction site – SpaceX is in the midst of building a new launch mount and modifying existing facilities to support future launches of SpaceX’s next-generation Starship vehicle. Construction has been underway for a few months and is situated directly beside Falcon 9 and Falcon Heavy’s exiting launch mount.
-->Although that construction will not be allowed to interfere with Crew Dragon launch activity, including the IFA test, construction on the Starship mount will likely be impacted. Construction crews will undoubtedly be expected to evacuate the area surrounding the launchpad during any Falcon 9 static fire test or launch, likely translating to a few days to a few weeks of downtime depending on how SpaceX handles the scheduling.
As 2019 comes to a close, SpaceX remains determined to launch Crew Dragon’s IFA test as quickly as is safely possible. If all goes perfectly during the upcoming abort test, SpaceX says it is seriously targeting Crew Dragon’s biggest test yet – its inaugural astronaut launch – less than two months later in February 2020. It should go without saying that that schedule is incredibly ambitious and highly liable to slip in March or Q2, but if the ambition is there, SpaceX believes it is technically possible.
For now, we have less than a month to wait for Crew Dragon’s next launch milestone and perhaps just 2-3 weeks before the spacecraft and its Falcon 9 rocket roll out to Pad 39A to prepare for a routine static fire test.

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.
