SpaceX dropped a Crew Dragon mockup to save a helicopter and its passengers
SpaceX says it encountered an issue that forced it to drop a Crew Dragon spacecraft mockup during parachute testing — not a failure of the vehicle or its parachutes, to be clear, but still a problem nonetheless.
This is now the second significant hurdle SpaceX’s Crew Dragon astronaut spacecraft has faced in the last few days, following the revelation that NASA will not permit the company to launch astronauts until it completes an investigation into an in-flight rocket engine failure during its March 18th Starlink launch. There is likely no technical corollary for the new Falcon 9 rockets that will launch NASA astronauts, but existing Commercial Crew Program (CCP) contract rules still require SpaceX’s internal investigation be completed before it can proceed. With lives on the line, caution – within reason – is unequivocally preferable to the alternative.
Thankfully, SpaceX’s parachute test article anomaly should have a much smaller impact on Crew Dragon’s astronaut launch debut schedule, but it’s unlikely to have zero impact.
“During a planned parachute drop test [on Tuesday], the test article suspended underneath the helicopter became unstable. Out of an abundance of caution and to keep the helicopter crew safe, the pilot pulled the emergency release. As the helicopter was not yet at target conditions, the test article was not armed, and as such, the parachute system did not initiate the parachute deployment sequence. While the test article was lost, this was not a failure of the parachute system and most importantly no one was injured. NASA and SpaceX are working together to determine the testing plan going forward in advance of Crew Dragon’s second demonstration mission.”
SpaceX — March 24th, 2020
On March 24th, SpaceX says it was preparing for one of the last system-level Crew Dragon parachute tests planned before the spacecraft can be declared ready for human spaceflight. These final tests are reportedly focused on corner cases, referring to unusual but not impossible scenarios the spacecraft might encounter during operational astronaut landing attempts. Those likely include parachute deployment scenarios that are far more stressful than a nominal reentry, descent, and landing would allow.
-->Regardless, things did not go as planned during Tuesday’s test attempt. SpaceX primarily uses cargo planes, helicopters, and large balloons to carry its Crew Dragon test articles (not actual functional spacecraft) to the altitudes and speeds needed to achieve certain test conditions. On March 24th, SpaceX was using a helicopter – either a civilian Blackhawk or a much larger Skycrane.
For unknown reasons, the helicopter carrying the Crew Dragon test article on March 24th began to experience “instability”, likely referring to some sort of resonance (wobble, sway, oscillation, etc). Out of an abundance of caution, the pilot – likely highly trained – decided the instability was becoming an unacceptable risk and chose to drop the cargo load (a Crew Dragon mockup). Unsurprisingly, the parachute test article was not ready to drop and plummeted to the Earth without any kind of parachute deployment, likely pancaking on the desert floor shortly thereafter.
Again, it needs to be noted – as SpaceX did above – that the loss of the Crew Dragon parachute test article was entirely unrelated to the performance of the spacecraft or the parachutes it was testing. The mockup destroyed in the incident is essentially just a boilerplate mass simulator shaped like a Crew Dragon capsule to achieve more aerodynamically accurate test results. As such, it’s far simpler and cheaper than an actual Dragon spacecraft and shouldn’t take long at all to replace if SpaceX doesn’t already have a second similar mockup ready to go.
Thankfully, that means that the loss of the test article should have next to no serious impact on Crew Dragon’s inaugural astronaut launch schedule. Planned no earlier than (NET) mid-to-late May according to NASA’s latest official statement, SpaceX and the space agency still have at least a month and a half to work through a final parachute test campaign, complete an investigation into Starlink L6’s Falcon booster engine failure, and finish several trees worth of paperwork and reviews. Delays remain likely but they shouldn’t be more than a few weeks, barring any future surprises.

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.
