SpaceX's Crew Dragon astronaut launch debut schedule revealed by Elon Musk
On the heels of a brand new animation simulating the spacecraft’s next orbital launch milestone, SpaceX CEO Elon Musk has revealed a tentative schedule for Crew Dragon’s astronaut launch debut.
Known as Demo-2, short for Crew Dragon’s second orbital demonstration mission, the launch could make SpaceX the first commercial company in history to send astronauts to space (i.e. orbit), as well as the first private company to deliver astronauts to the International Space Station (ISS). If things go as planned over the next several months, that should kick off a new era where NASA will routinely rely on SpaceX (and Boeing) to ensure that the US has a continued presence in space.
The International Space Station has been continuously crewed by astronauts since October 31st, 2000, representing nearly two decades that humanity has had an uninterrupted presence in space. Supported by regular NASA Space Shuttle and Russian Soyuz launches that enabled space agencies to safely send astronauts to and from the space station, SpaceX’s Crew Dragon and Boeing’s Starliner are nearly ready to pick up the torch that NASA and the United States fumbled when the Shuttle was prematurely canceled in 2011.
Over the last five years, SpaceX has been working tirelessly to design, build, and test Crew Dragon – all in the name of ensuring that it will be one of the most reliable and capable human-rated spacecraft ever flown once it begins taking astronauts to and from the ISS. As with almost all human-rated spacecraft in history, Crew Dragon’s development has not been without its hurdles and detours, ranging from challenges with the spacecraft’s parachute recovery systems to a catastrophic capsule explosion during thruster testing.
As a result, SpaceX has put extra effort into optimizing and redesigning Crew Dragon’s many subsystems to ensure that all work exactly as intended. Thankfully, all of Crew Dragon’s development hurdles have occurred during testing specifically designed to reveal such problems, meaning that no humans have been harmed (or killed) over the course of the program. In the history of human spaceflight, it has often been the case that catastrophic spacecraft failure modes are only discovered after operational flights began, resulting in the deaths of numerous astronauts during Soyuz, Space Shuttle, and SpaceShipTwo – as well as three NASA astronauts during Apollo 1 ground testing.

Spaceflight is nevertheless a dangerous endeavor, at least for the time being, so it’s entirely possible that Crew Dragon will ultimately suffer accidents or failures during crewed missions, evidenced most recently by Starliner’s failure to reach the space station during the Boeing’s spacecraft’s first orbital launch. Still, both companies are working hard to ensure that even in the event of a failure, their spacecraft are able to protect their astronaut passengers and safely return them to Earth.
In line with that, SpaceX (unlike Boeing) opted to perform a live In-Flight Abort (IFA) test with Crew Dragon before allowing the spacecraft to begin astronaut launches. Scheduled to launch as early as January 11th, SpaceX will launch a Dragon spacecraft atop Falcon 9 and simulate a rocket failure during the most stressful point of launch. If Crew Dragon can fire up its abort thrusters and whisk its hypothetical passengers to safety, chances are that the spacecraft will be able to do the same at any other point during launch – from before liftoff all the way to orbit.
SpaceX has been developing its first human-rated spacecraft since it began build Cargo Dragon more than a decade ago – all paths for the company have ultimately pointed towards human spaceflight. According to CEO Elon Musk, the Crew Dragon spacecraft and Falcon 9 launch vehicle assigned to support the company’s inaugural astronaut launch will be in Florida and ready for flight as early as February 2020, a few-month delay compared to the often overly-optimistic executive’s previous Nov/Dec 2019 target.
Although the hardware could be ready to launch three months (or less) from now, Musk believes that the NASA preflight reviews that must follow will likely take “a few more months” – unfortunately likely given that Crew Dragon’s uncrewed launch debut (Demo-1) was likely ready for flight almost two months before NASA finally cleared SpaceX to launch.
Ultimately, as long as Crew Dragon’s IFA test goes well next month, it’s likely that the spacecraft will launch twice in the first half of 2020, potentially making history sometime in the second quarter.

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.
