SpaceX's next Crew Dragon launch is delayed but that's actually good news
NASA says that SpaceX’s next big Crew Dragon flight test has slipped a bit further into 2020, a counterintuitively positive sign that the human-rated spacecraft’s next launch is firmly scheduled for the first month of the next decade.
Known as Crew Dragon’s In-Flight Abort (IFA) test, SpaceX opted to include the mission in its Commercial Crew contract, a decision NASA chose to leave up to its providers. Boeing, for example, chose not to perform a real-world in-flight abort test of its Starliner spacecraft, instead relying on a pad abort test and digital modeling to determine the spacecraft’s capabilities. NASA allowed this flexibility because it believes – at least theoretically – that it should be possible to determine whether a spacecraft can perform the most challenging abort scenarios without actually doing full-fidelity flight tests.
Given that NASA chose to perform an extremely expensive full-fidelity in-flight abort test with its own Orion spacecraft just a few months ago, one can’t exactly say that the space agency has chosen to reap what it’s sown, but with any luck, the Starliner spacecraft will never have to perform such an abort and find out how close Boeing’s modeling is to reality.
It’s also worth noting that despite the fact SpaceX elected to perform an extra abort test that will likely destroy an entire Falcon 9 rocket, Crew Dragon development will cost NASA $2 billion (40%) less than Starliner, while each operational Crew Dragon launch will also cost some $250 million (39%) less than a comparable Starliner launch.
As of December 18th, NASA says that SpaceX’s In-Flight Abort (IFA) test has slipped a week from January 4th to January 11th, 2020. Counterintuitively, that delay is actually an extremely encouraging sign that Crew Dragon’s next launch is quite firmly set for the first month of 2020. For reference, as NASA and SpaceX approached Crew Dragon’s Demo-1 orbital launch debut earlier this year, the mission was initially set for January 17th. Around three weeks later, NASA announced that Demo-1 had slipped to no earlier than (NET) “February”. Four weeks after that delay, NASA once again announced another delay to March 2nd, which would turn out to be the day that Crew Dragon really did reach orbit for the first time.

On the other hand, IFA – Crew Dragon’s second launch – had its first firm launch date (January 4th) announced by NASA on December 6th, 2019. Less than two weeks later, NASA says that the launch date has slipped by exactly one week to January 11th, less than four weeks from today. It’s entirely possible that SpaceX’s IFA test will slip further into 2020 in the coming weeks, but compared to Crew Dragon’s Demo-1 mission, both NASA and SpaceX appear to be far more confident in the schedule for Crew Dragon’s second launch.
Regardless of when exactly it lifts off, Crew Dragon’s In-Flight Abort is going to be an extremely challenging test for the spacecraft. Designed to simulate a near-worst-case abort scenario during launch, SpaceX will essentially trick Dragon into believing that Falcon 9 has failed around a minute and a half after launch. At that point, the rocket and spacecraft will be traveling as fast as Mach 2.5 (860 m/s, 1900 mph) and experiencing what is known as Max Q, the point of peak aerodynamic stress (referring to heating, buffeting, pressure, and more).
At that exact point, Crew Dragon capsule C205 will ignite all eight of its SuperDraco abort engines, almost instantaneously producing 130,000 lbf (570 kN) of thrust to send the spacecraft almost a kilometer (0.5 mi) away from Falcon 9 in just a few seconds. If Crew Dragon survives the ordeal, it will quickly detach its trunk section, flip around to face its heat shield towards the ground, and ultimately deploy parachutes before gently landing in the Atlantic Ocean.
SpaceX plans to recover and reuse the otherwise orbit-worthy capsule on a future mission, likely one of the company’s upcoming CRS2 space station resupply launches. Finally, if everything goes exactly as planned during the In-Flight Abort test and both NASA and SpaceX see no issues with the flown hardware or data the test produces, Crew Dragon Demo-2 – the spacecraft’s first astronaut launch – could potentially be ready for flight as early as February or March 2020.

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.
