SpaceX Dragon spacecraft caught by robotic space station arm for the last time
On March 9th, SpaceX’s CRS-20 Cargo Dragon completed an uneventful journey to the International Space Station (ISS), where the spacecraft was successfully captured giant robotic arm for the last time.
Barring several major surprises, Dragon’s March 9th capture was the last time a SpaceX spacecraft berthed with a space station for the foreseeable future – possibly forever. Referring to the process of astronauts manually catching visiting vehicles and installing them on an airlock with a giant, robotic arm, berthing is a much younger technology than docking and was developed as an alternative for a few particular reasons. Perhaps most importantly, the Common Berthing Mechanism (CBM) ports used by Cargo Dragon, Cygnus, and HTV spacecraft are more than 60% wider than standard docking ports. In other words, spacecraft that berth can transport substantially larger pieces of cargo to and from the space station.
More significantly, however, the CBM standard came about in large part due to the decision to assemble the ISS out of 16 pressurized segments, each separately launched into orbit. Measuring about 1.25m (4.2 ft) wide, the CBM ports that connect most of the space station’s 16 livable segments make the ISS far more practical for the astronauts that crew it, while also allowing for larger hardware to be moved between each module. With Crew Dragon, design requirements meant that SpaceX had to move from berthing to docking, a trait SpaceX thus carried over when it chose to base its Cargo Dragon replacement on a lightly-modified Crew Dragon design.
Now verging on routine, Cargo Dragon capsule C112 began its final approach to the International Space Station on March 9th, pausing at set keep-out zones while SpaceX operators waited for NASA and ISS approval to continue. After several stops, Dragon arrived at the last hold point – some 10m (33 ft) away from the station – and NASA astronaut Jessica Meir manually steered Canadarm2 to a successful capture, quite literally grabbing Dragon with a sort of mechanical hand.
At that point, Dragon – like a large ship arriving in port with the help of tugboats – is in the hands of external operators. At the ISS, Canadarm2 essentially flips itself around with Dragon still attached, carefully and slowly mating the spacecraft with one of the station’s free berthing ports. Unlike docking ports, the active part of a berthing port is located on the station’s receiving end, where electromechanical latches and bolts permanently secure the spacecraft to the station and ensure a vacuum seal.
Finally, once berthing is fully complete, ISS astronauts can manually open Dragon’s hatch, giving them access to the two or so metric tons (~4000 lb) of cargo typically contained within. All told, the process of berthing is relatively intensive and expensive in terms of the amount of time station astronauts and NASA ground control must spend to complete a single resupply mission. From start to finish, excluding training, berthing takes a crew of two station astronauts some 9-12 hours of near-continuous work from spacecraft approach to hatch open.
One definite benefit of the docking approach Crew Dragon and Cargo Dragon 2 will use is just how fast it is compared to berthing. Because docking is fundamentally autonomous and controlled by the spacecraft instead of the station, it significantly reduces the workload placed on ISS astronauts. Crew members must, of course, remain vigilant and pay close attention during the critical approach period, particularly with uncrewed Cargo Dragon 2 spacecraft. However, the assumption is always that the spacecraft will independently perform almost all tasks related to docking, short of actually offloading cargo and crew.
For now, CRS-20 will likely be SpaceX’s last uncrewed NASA cargo mission for at six months. CRS-21 – Cargo Dragon 2’s launch debut – is currently scheduled no earlier than (NET) Q4 2020. Nevertheless, Crew Dragon’s next launch – also its astronaut launch debut – could lift off as early as May 2020, just two months from now. With both SpaceX’s crew and cargo missions soon to consolidate around a single spacecraft, the odds are good that Dragon 2 will wind up flying far more than Dragon 1, and the start of its increasingly common launches is just around the corner.

Tesla Europe builds momentum with expanding FSD demos and regional launches
Needless to say, it appears that Tesla is putting in some serious effort into boosting sales in Europe this year.
Tesla has been notably active across Europe in recent weeks, expanding its Full Self-Driving (Supervised) ride-along program, entering a new market, and showcasing its newest vehicles across multiple regions.
Needless to say, it appears that Tesla is putting in some serious effort into boosting sales in Europe this year.
Tesla Europe recently announced the expansion of its FSD (Supervised) ride-along experiences, inviting the public to experience the system on local roads. Initially available in Italy, France, and Germany when it launched, the program has now expanded to Hungary, Finland, and Spain.
The ride-along program allows participants to ride in the passenger seat and observe how FSD Supervised handles real-world traffic scenarios, including dense urban driving and other challenging conditions. Tesla has positioned the initiative as a way to familiarize European drivers and regulators with the system’s capabilities in everyday use. The program has received positive reviews so far, with many being impressed by FSD’s real-world capabilities.
Tesla also recently launched operations in Slovakia with a pop-up store and multi-day public event in Bratislava, as noted in an EV Wire report. The launch, held from January 16 to 18 at the Eurovea Mall Promenade, featured test drives, vehicle displays, including the Cybertruck, as well as family-focused attractions such as a mini-Tesla racetrack.
Local observers noted that Tesla Optimus was also shown at the event, while the Tesla Owners Slovakia club welcomed the brand with a coordinated light show near the Slovak National Theater. Tesla Europe later shared its appreciation for Slovakia in a post on its official social media account on X, stating, “Thanks, Slovakia, for the amazing last 3 days & for giving us such a warm welcome!”
Tesla’s Slovakia entry follows a familiar pattern used by the company in other European markets. Tesla opened a pop-up store in Bratislava as an initial step, with plans for a permanent showroom and a potential service center at a renovated site previously occupied by a Jeep and Dodge dealership. Tesla has used a similar approach in markets such as Czechia and Lithuania, where permanent facilities followed within a few months of pop-up launches.
Slovakia already has six Supercharging sites totaling 46 Superchargers, including two locations in Bratislava, providing early infrastructure support for Tesla owners. Tesla staff program manager Supratik Saha described the Slovakia launch as a strategic expansion in the heart of the EU, citing the country’s strong automotive manufacturing base and appetite for advanced technology.
Beyond the EU, the company also marked another milestone with the first Cybertruck deliveries in the United Arab Emirates, signaling continued geographic expansion for Tesla’s newest vehicle. Just like Tesla Slovakia, the Cybertruck also received a warm welcome from the UAE’s EV community.

Tesla Sweden maintains Trelleborg port deal despite union blockade
As noted in a report from Dagens Arbete (DA), Tesla was able to maintain its storage agreement with the Port of Trelleborg.
Tesla Sweden is still storing vehicles at the Port of Trelleborg despite the ongoing blockades against the company from the country’s labor unions.
Tesla still at Port of Trelleborg
As noted in a report from Dagens Arbete (DA), Tesla was able to maintain its storage agreement with the Port of Trelleborg. This allows the company to keep vehicles at the port while imports into Sweden continue. This was despite the Transport Workers’ Union’s blockade, which was aimed at halting the loading and unloading of Tesla vehicles in the area.
Local union leader Jörgen Wärja, chairman of Transport and an employee representative on the port company’s board, confirmed that the agreement was still active. “The agreement has not been terminated. You want to have the money instead of having empty warehouses. I understand the reason, but I do not support it,” Wärja said
The local union leader also noted that he visited Tesla’s storage area earlier this week. “There were a lot of cars. I was surprised that there were so many, actually,” he said.
Tesla had been able to bring vehicles into Sweden via passenger ferries at Trelleborg, a method that unions said allowed the company to bypass the blockade, DA noted. According to estimates from IF Metall, the workaround enabled Tesla to deliver thousands of cars to Sweden each year.
Port defends decision
The Port of Trelleborg did not issue a comment on its current agreement with Tesla, but said it had complied with union sympathy measures. Documents reviewed by Swedish media showed that the contract with Tesla was being extended in six-month intervals.
Port CEO Malin Collin noted that the port would not discuss individual customer arrangements. “We do not go into details regarding any customer agreements. We have continuous dialogue with potential tenants, and this is not unique to any location,” Collin wrote in an email.
The CEO added that the port was following legal requirements related to the labor dispute. “We have taken note of the Transport Workers’ Union’s decision on sympathy measures and are of course following applicable legislation and the requirements placed on us as employers,” Collin said.
Jörgen Wärja, for his part, stated that the issue was not whether Tesla’s imports into Sweden could be fully stopped, but whether the port should provide logistical support to the electric vehicle maker during an active conflict. “The port shouldn’t have anything to do with Tesla at all, we believe,” he said. “It’s purely moral. Whether you honor a conflict or not. If you say you support Transport’s sympathetic actions against Tesla, it becomes a double standard.”

Elon Musk shares insights on SpaceX and Tesla’s potential scale
In a pair of recent posts on X, Musk argued that both companies operate in domains where growth is not linear, but exponential.
Elon Musk outlined why he believes Tesla and SpaceX ultimately dwarf their competitors, pointing to autonomy, robotics, and space-based energy as forces that fundamentally reshape economic scale.
In a pair of recent posts on X, Musk argued that both companies operate in domains where growth is not linear, but exponential.
Space-based energy
In a response to a user on X who observed that SpaceX has a larger valuation than all six US defense companies combined, Musk explained that space-based industries will eventually surpass the total economic value of Earth. He noted that space allows humanity to harness roughly 100,000 times more energy than Earth currently uses, while still consuming less than a millionth of the Sun’s total energy output.
That level of available energy should enable the emergence and development of industries that are simply not possible within Earth’s physical and environmental constraints. Continuous solar exposure in space, as per Musk’s comment, removes limitations imposed by atmosphere, weather, and land availability.
Autonomy and robots
In a follow-up post, Elon Musk explaned that “due to autonomy, Tesla is worth more than the rest of the auto industry.” Musk added that this assessment does not yet account for Optimus, Tesla’s humanoid robot. As per the CEO, once Optimus reaches scaled production, it could increase Earth’s gross domestic product by an order of magnitude, ultimately paving the way for sustainable abundance.
Even before the advent of Optimus, however, Tesla’s autonomous driving system already gives vehicles the option to become revenue-generating assets through services like the Tesla Robotaxi network. Tesla’s autonomous efforts seem to be on the verge of paying off, as services like the Robotaxi network have already been launched in its initial stages in Austin and the Bay Area.
