SpaceX has released a rare video from one of its slow-motion engineering cameras, showing off a Crew Dragon capsule performing a static fire test of its eight SuperDraco rocket engines. With this test now complete, SpaceX and NASA can focus on determining when the same Dragon will be ready to fly a crucial abort test.

After a week or two of delays, on November 13th, SpaceX successfully fired up Crew Dragon capsule C205’s eight SuperDraco abort engines and two Draco maneuvering thrusters in a ground simulation of a flight test planned for the same capsule. Crew Dragon’s eight SuperDraco thrusters are capable of producing a combined thrust of more than 130,000 lbf (570 kN), almost as much thrust as an original SpaceX Merlin 1D engine used on Falcon 9s in the early 2010s.

November 13th’s static fire was required only after Crew Dragon C201 catastrophically exploded just prior to an almost identical test on April 20th, 2019. The historic spacecraft had completed its first orbital launch, ISS rendezvous, docking, reentry, and splashdown less than six weeks prior to that attempted static fire. Although it performed to perfection during that uncrewed Demo-1 spaceflight, it apparently carried an unknown design flaw during that flawless launch.

That flaw became apparent after the spacecraft exploded around 10 seconds prior to a planned static fire of its SuperDraco engines, a test meant to verify vehicle health before SpaceX planned to launch the capsule again to support its In-Flight Abort (IFA). According to a joint SpaceX-NASA investigation, the source of that failure was the flawed decision to use titanium in a pressurized liquid nitrogen tetroxide (NTO) environment, a choice that ultimately resulted in an exotic titanium fire and violent explosion.

SpaceX decided to prevent the issue from recurring by replacing the actuating, titanium check valves with single-use burst disks, meaning that Crew Dragon’s SuperDraco engines will now only be capable of a single ignition each. That limitation is no longer relevant after SpaceX chose years ago to end work on propulsively landing Dragon spacecraft (a la Falcon boosters), thus presumably making burst disks the simplest, cheapest, and fastest change for SpaceX and NASA to re-certify.

Thanks to the speed with which SpaceX was able to respond to Crew Dragon’s April 2019 explosion, the company was able to shuffle its fleet of in-process spacecraft, reassign capsule C205 to Dragon’s IFA test, modify the vehicle to account for necessary changes, ship it to Florida, and static-fire the completed spacecraft a little over six months later. With that static fire test now fully complete and NASA and SpaceX deep into the process of carefully inspecting capsule C205 and poring over the data produced, it’s finally reasonable to start thinking seriously about Crew Dragon’s next flight milestone.

Known as the spacecraft’s In-Flight Abort (IFA) test, that milestone will see capsule C205 launch atop a Falcon 9 booster and upper stage and attempt to escape the rocket after reaching supersonic speeds. That point of maximum aerodynamic and thermal stress during launch – known as Max Q – is one of the most challenging abort scenarios Crew Dragon could face. If C205 is able to successfully perform that in-flight abort, it will verify that the spacecraft is capable of carrying its astronauts to safety at almost any point in flight, from the launch pad all the way to Earth orbit.

NASA and SpaceX will likely announce the IFA launch date within the next week or two and odds remain good that Crew Dragon will be able to fly again before the end of 2019.

Tesla adjusts crucial feature as winter weather arrives

Tesla has adjusted the functionality of a crucial climate feature as Winter weather has started to arrive throughout some parts of the United States. The new feature was highly requested by owners.

Tesla has a Cabin Overheat Protection feature that helps keep the temperature regulated if it reaches a certain threshold. Inversely, it can be used in cold weather as well, which will automatically warm the cabin if it sinks to a temperature that is too low for the owner’s comfort.

This is a great way to keep the cabin either warmed up just enough or cooled down just enough so that it never gets too hot or too cold. Extreme temperatures could damage certain parts of the vehicle or damage personal belongings that are kept inside the car.

Overheat protection is a great thing to have in hot climates like Arizona or Texas, especially with the Premium trims of the Model 3 and Model Y, which feature a glass roof.

Many owners appreciate the feature, but they argue that using it at home will utilize too much energy, especially during extreme temperatures. For a while, many Tesla fans have requested an option to disable this feature when the car is parked at home, which the company recently added, according to Not a Tesla App.

The feature is part of Software Version 2025.44.3, and the release notes state:

“You can now choose Exclude Home when Cabin Overheat Protection or No A/C is enabled.”

Tesla has been great at listening to what owners want with new features, and this is one that will reserve some charge and prevent unnecessary utilization of available power, especially as the car is parked at home. If owners want to condition the cabin or get the car ready for operation with a comfortable interior, they can utilize the Tesla app to adjust the climate.

Tesla CEO Elon Musk sends rivals dire warning about Full Self-Driving

Tesla CEO Elon Musk revealed today on the social media platform X that legacy automakers, such as Ford, General Motors, and Stellantis, do not want to license the company’s Full Self-Driving suite, at least not without a long list of their own terms.

“I’ve tried to warn them and even offered to license Tesla FSD, but they don’t want it! Crazy,” Musk said on X. “When legacy auto does occasionally reach out, they tepidly discuss implementing FSD for a tiny program in 5 years with unworkable requirements for Tesla, so pointless.”

Musk made the remark in response to a note we wrote about earlier today from Melius Research, in which analyst Rob Wertheimer said, “Our point is not that Tesla is at risk, it’s that everybody else is,” in terms of autonomy and self-driving development.

Wertheimer believes there are hundreds of billions of dollars in value headed toward Tesla’s way because of its prowess with FSD.

A few years ago, Musk first remarked that Tesla was in early talks with one legacy automaker regarding licensing Full Self-Driving for its vehicles. Tesla never confirmed which company it was, but given Musk’s ongoing talks with Ford CEO Jim Farley at the time, it seemed the Detroit-based automaker was the likely suspect.

Ford has been perhaps the most aggressive legacy automaker in terms of its EV efforts, but it recently scaled back its electric offensive due to profitability issues and weak demand. It simply was not making enough vehicles, nor selling the volume needed to turn a profit.

Musk truly believes that many of the companies that turn their backs on FSD now will suffer in the future, especially considering the increased chance it could be a parallel to what has happened with EV efforts for many of these companies.

Unfortunately, they got started too late and are now playing catch-up with Tesla, XPeng, BYD, and the other dominating forces in EVs across the globe.

Tesla backtracks on strange Nav feature after numerous complaints

Tesla is backtracking on a strange adjustment it made to its in-car Navigation feature after numerous complaints from owners convinced the company to make a change.

Tesla’s in-car Navigation is catered to its vehicles, as it routes Supercharging stops and preps your vehicle for charging with preconditioning. It is also very intuitive, and features other things like weather radar and a detailed map outlining points of interest.

However, a recent change to the Navigation by Tesla did not go unnoticed, and owners were really upset about it.

Tesla’s Navigation gets huge improvement with simple update

For trips that required multiple Supercharger stops, Tesla decided to implement a naming change, which did not show the city or state of each charging stop. Instead, it just showed the business where the Supercharger was located, giving many owners an unwelcome surprise.

However, Tesla’s Director of Supercharging, Max de Zegher, admitted the update was a “big mistake on our end,” and made a change that rolled out within 24 hours:

The lack of a name for the city where a Supercharging stop would be made caused some confusion for owners in the short term. Some drivers argued that it was more difficult to make stops at some familiar locations that were special to them. Others were not too keen on not knowing where they were going to be along their trip.

Tesla was quick to scramble to resolve this issue, and it did a great job of rolling it out in an expedited manner, as de Zegher said that most in-car touch screens would notice the fix within one day of the change being rolled out.

Additionally, there will be even more improvements in December, as Tesla plans to show the common name/amenity below the site name as well, which will give people a better idea of what to expect when they arrive at a Supercharger.
