SpaceX’s Cargo Dragon has successfully rendezvoused with the International Space Station (ISS) as part of NASA’s CRS-19 resupply mission, marking what is almost certainly the spacecraft’s second to last orbital launch.

On December 5th, new Falcon 9 booster B1059 lifted off from SpaceX’s LC-40 Cape Canaveral Air Force Station (CCAFS) launch pad with a fresh upper stage and twice flown Cargo Dragon capsule C106 atop it. A little over nine minutes after launch, B1059 prepared to be robotically secured on drone ship Of Course I Still Love You (OCISLY) while Cargo Dragon – now in orbit – separated from Falcon 9’s upper stage and headed on its merry way.

Cargo Dragon’s 20th orbital mission and 19th trip to the ISS, CRS-19’s twice-flown spacecraft commanded the deployment of its two solar arrays, primed its Draco maneuvering thrusters, and opened up its Guidance, Navigation, and Control (GNC) bay. Using star trackers, inertial measurement devices, and lasers, Dragon then proceeded to precisely deliver itself to the ‘door’ of the space station before gradually approaching.

Astronauts aboard the ISS then manually guided Canadarm2 – a massive robotic arm externally attached to the space station – towards Cargo Dragon as it used its thrusters to essentially hover in place, ultimately grabbing the spacecraft with a sort of mechanical hand. At that point, Dragon effectively became a part of the ISS and astronauts monitored the subsequent (and mostly automated) process of using Canadarm2 to fully berth spacecraft with the station.

After berthing, astronauts are able to equalize the pressure between the ISS and visiting spacecraft and open the hatch, gaining access to whatever cargo it was loaded with prior to launch. Alternatively, visiting vehicles can also dock with the International Space Station, a process controlled entirely by the arriving spacecraft, a bit like berthing but with almost all of the risk on its shoulders. All Russian spacecraft currently use this method, as do Boeing’s Starliner and SpaceX’s Crew Dragon.

As it turns out, CRS-19 – partially hinted at in the name – is the second to last launch of SpaceX’s Dragon 1 (Cargo Dragon), which become the first commercial spacecraft capable of reentering Earth’s atmosphere in 2010 and rendezvousing with a space station in 2012. Five months later, SpaceX launched CRS-1 – its first operational resupply mission – and the rest is (more or less) history.

In the seven years since CRS-1, Cargo Dragon – including CRS-19 – has now flown 18 successful space station resupply missions and delivered more than 90,000 lb (50,000 kg) to its ever-changing crew of astronauts. Cargo Dragon has undergone at least two significant upgrades and suffered its fair share of mishaps, but has still successfully completed its mission every time it reached orbit.

NASA’s CRS1 SpaceX contract ultimately called for a total of 20 Cargo Dragon missions to the ISS, although more could technically be added retroactively if both entities were to decide they were needed. Currently, the plan is for CRS-20 – Cargo Dragon’s next launch – to be the spacecraft’s last orbital mission and is scheduled no earlier than March 2020.

After CRS-20, SpaceX – via its subsequent CRS2 NASA contract – means to introduce a version of Crew Dragon (Dragon 2) modified for cargo-only missions, optimally taking flight-proven Crew capsules and reusing them as Cargo Dragon 2s.

SpaceX recently revealed that the first Cargo Dragon 2 spacecraft will unexpectedly not feature Crew Dragon’s complex SuperDraco abort system, a feature that has recently created several roadblocks. However, this dramatically simplifies Dragon 2 and means that SpaceX is still quite confident that the upgraded cargo spacecraft will be ready for its launch debut next year.

Known as CRS-21, that mission will see SpaceX’s CRS launches move from LC-40 to Kennedy Space Center’s LC-39A pad in order to enable extremely late and convenient cargo-loading via Pad 39A’s Crew Access Arm (CAA), to be primarily used by astronauts boarding Crew Dragon. Similarly, Cargo Dragon 2 will dock with the ISS instead of using Dragon’s current berthing route, nominally requiring less hands-on astronaut time for each resupply mission.

Cargo Dragon will be missed but will forever remain a major piece of commercial spaceflight history. Dragon 2 will likely toe the line for the first half of the next decade, but SpaceX ultimately wants to get its generation Starship launch vehicle online as soon as possible – a feat that will make all Falcon and Dragon vehicles redundant if things go as planned.

Anti-Tesla union leader ditches X, urges use of Threads instead

Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.

Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.

Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now. 

Anti-Tesla union leader exits X

In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.

“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.

Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant. 

“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.

IF Metall sees Threads as an X alternative

After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.

Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.

“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.

Elon Musk confirms SpaceX is not developing a phone

Despite many recent rumors and various reports, Elon Musk confirmed today that SpaceX is not developing a phone based on Starlink, not once, but twice.

Today’s report from Reuters cited people familiar with the matter and stated internal discussions have seen SpaceX executives mulling the idea of building a mobile device that would connect directly to the Starlink satellite constellation.

Musk did state in late January that SpaceX developing a phone was “not out of the question at some point.” However, He also said it would have to be a major difference from current phones, and would be optimized “purely for running max performance/watt neural nets.”

While Musk said it was not out of the question “at some point,” that does not mean it is currently a project SpaceX is working on. The CEO reaffirmed this point twice on X this afternoon.

Musk said, “Reuters lies relentlessly,” in one post. In the next, he explicitly stated, “We are not developing a phone.”

Musk has basically always maintained that SpaceX has too many things going on, denying that a phone would be in the realm of upcoming projects. There are too many things in the works for Musk’s space exploration company, most notably the recent merger with xAI.

SpaceX officially acquires xAI, merging rockets with AI expertise

A Starlink phone would be an excellent idea, especially considering that SpaceX operates 9,500 satellites, serving over 9 million users worldwide. 650 of those satellites are dedicated to the company’s direct-to-device initiative, which provides cellular coverage on a global scale.

Nevertheless, there is the potential that the Starlink phone eventually become a project SpaceX works on. However, it is not currently in the scope of what the company needs to develop, so things are more focused on that as of right now.

Tesla adds notable improvement to Dashcam feature

Tesla has added a notable improvement to its Dashcam feature after complaints from owners have pushed the company to make a drastic change.

Perhaps one of the biggest frustrations that Tesla owners have communicated regarding the Dashcam feature is the lack of ability to retain any more than 60 minutes of driving footage before it is overwritten.

It does not matter what size USB jump drive is plugged into the vehicle. 60 minutes is all it will hold until new footage takes over the old. This can cause some issues, especially if you were saving an impressive clip of Full Self-Driving or an incident on the road, which could be lost if new footage was recorded.

This has now been changed, as Tesla has shown in the Release Notes for an upcoming Software Update in China. It will likely expand to the U.S. market in the coming weeks, and was first noticed by NotaTeslaApp.

The release notes state:

“Dashcam Dynamic Recording Duration – The dashcam dynamically adjusts the recording duration based on the available storage capacity of the connected USB drive. For example, with a 128 GB USB drive, the maximum recording duration is approximately 3 hours; with a 1 TB or larger USB drive, it can reach up to 24 hours. This ensures that as much video as possible is retained for review before it gets overwritten.”

Tesla Adds Dynamic Recording

Instead of having a 60-minute cap, the new system will now go off the memory in the USB drive. This means with:

  • 128 GB Jump Drive – Up to Three Hours of Rolling Footage
  • 1TB Jump Drive – Up to 24 Hours of Rolling Footage

This is dependent on the amount of storage available on the jump drive, meaning that if there are other things saved on it, it will take away from the amount of footage that can be retained.

While the feature is just now making its way to employees in China, it will likely be at least several weeks before it makes its way to the U.S., but owners should definitely expect it in the coming months.

It will be a welcome feature, especially as there will now be more customization to the number of clips and their duration that can be stored.
