SpaceX Crew Dragon tests SuperDraco rocket engines in new slow-mo video
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 investors will be shocked by Jim Cramer’s latest assessment
Jim Cramer is now speaking positively about Tesla, especially in terms of its Robotaxi performance and its perception as a company.

Tesla investors will be shocked by analyst Jim Cramer’s latest assessment of the company.
When it comes to Tesla analysts, many of them are consistent. The bulls usually stay the bulls, and the bears usually stay the bears. The notable analysts on each side are Dan Ives and Adam Jonas for the bulls, and Gordon Johnson for the bears.
Jim Cramer is one analyst who does not necessarily fit this mold. Cramer, who hosts CNBC’s Mad Money, has switched his opinion on Tesla stock (NASDAQ: TSLA) many times.
He has been bullish, like he was when he said the stock was a “sleeping giant” two years ago, and he has been bearish, like he was when he said there was “nothing magnificent” about the company just a few months ago.
Now, he is back to being a bull.
Cramer’s comments were related to two key points: how NVIDIA CEO Jensen Huang describes Tesla after working closely with the Company through their transactions, and how it is not a car company, as well as the recent launch of the Robotaxi fleet.
Jensen Huang’s Tesla Narrative
Cramer says that the narrative on quarterly and annual deliveries is overblown, and those who continue to worry about Tesla’s performance on that metric are misled.
“It’s not a car company,” he said.
He went on to say that people like Huang speak highly of Tesla, and that should be enough to deter any true skepticism:
“I believe what Musk says cause Musk is working with Jensen and Jensen’s telling me what’s happening on the other side is pretty amazing.”

Robotaxi Launch
Many media outlets are being extremely negative regarding the early rollout of Tesla’s Robotaxi platform in Austin, Texas.
There have been a handful of small issues, but nothing significant. Cramer says that humans make mistakes in vehicles too, yet, when Tesla’s test phase of the Robotaxi does it, it’s front page news and needs to be magnified.
He said:
“Look, I mean, drivers make mistakes all the time. Why should we hold Tesla to a standard where there can be no mistakes?”
It’s refreshing to hear Cramer speak logically about the Robotaxi fleet, as Tesla has taken every measure to ensure there are no mishaps. There are safety monitors in the passenger seat, and the area of travel is limited, confined to a small number of people.
Tesla is still improving and hopes to remove teleoperators and safety monitors slowly, as CEO Elon Musk said more freedom could be granted within one or two months.

Tesla launches ultra-fast V4 Superchargers in China for the first time
Tesla has V4 Superchargers rolling out in China for the first time.

Tesla already has nearly 12,000 Supercharger piles across mainland China. However, the company just initiated the rollout of the ultra-fast V4 Superchargers in China for the first time, bringing its quick-charging piles to the country for the first time since their launch last year.
The first batch of V4 Superchargers is now officially up and running in China, the company announced in a post on Chinese social media outlet Weibo today.
The company said in the post:
“The first batch of Tesla V4 Superchargers are online. Covering more service areas, high-speed charging is more convenient, and six-layer powerful protection such as rain and waterproof makes charging very safe. Simultaneously open to non-Tesla vehicles, and other brands of vehicles can also be charged. There are more than 70,000 Tesla Superchargers worldwide. The charging network layout covers 100% of the provincial capitals and municipalities in mainland China. More V4 Superchargers will be put into use across the country. Optimize the charging experience and improve energy replenishment efficiency. Tesla will accompany you to the mountains, rivers, lakes, and seas with pure electricity!”
The first V4 Superchargers Tesla installed in China are available in four cities across the country: Shanghai, Zhejiang, Gansu, and Chongqing.

Tesla has over 70,000 Superchargers worldwide. It is the most expansive and robust EV charging network in the world. It’s the main reason why so many companies have chosen to adopt Tesla’s charging connector in North America and Europe.
In China, some EVs can use Tesla Superchargers as well.
The V4 Supercharger is capable of charging vehicles at speeds of up to 325kW for vehicles in North America. This equates to over 1,000 miles per hour of charging.

Elon Musk hints at when Tesla could reduce Safety Monitors from Robotaxi
Tesla could be reducing Safety Monitors from Robotaxi within ‘a month or two,’ CEO Elon Musk says.

Elon Musk hinted at when Tesla could begin reducing Safety Monitors from its Robotaxis. Safety Monitors are Tesla employees who sit in the front passenger seat during the driverless rides, and are there to ensure safety for occupants during the earliest rides.
Tesla launched its Robotaxi fleet in Austin last Sunday, and after eight days, videos and reviews from those who have ridden in the driverless vehicles have shown that the suite is safe, accurate, and well coordinated. However, there have been a few hiccups, but nothing that has put anyone’s safety in danger.
A vast majority — close to all of the rides — at least according to those who have ridden in the Robotaxi, have been performed without any real need for human intervention. We reported on what was the first intervention last week, as a Safety Monitor had to step in and stop the vehicle in a strange interaction with a UPS truck.
Watch the first true Tesla Robotaxi intervention by safety monitor
The Tesla and UPS delivery truck were going for the same street parking space, and the Tesla began to turn into it. The UPS driver parallel parked into the spot, which was much smaller than his truck. It seemed to be more of an instance of human error instead of the Robotaxi making the wrong move. This is something that the driverless cars will have to deal with because humans are aggressive and sometimes make moves they should not.
The Safety Monitors have not been too active in the vehicles. After all, we’ve only seen that single instance of an intervention. There was also an issue with the sun, when the Tesla braked abnormally due to the glare, but this was an instance where the car handled the scenario and proceeded normally.
With the Robotaxi fleet operating impressively, some are wondering when Tesla will begin scaling back both the Safety Monitors and Teleoperators that it is using to ensure safety with these early rides.
CEO Elon Musk answered the inquiry by stating, “As soon as we feel it is safe to do so. Probably within a month or two.”
As soon as we feel it is safe to do so.
Probably within a month or two. We continue to improve the Tesla AI with each mile driven.
— Elon Musk (@elonmusk) June 30, 2025
Musk’s response seems to confirm that there will be fewer Teleoperators and Safety Monitors in the coming months, but there will still be some within the fleet to ensure safety. Eventually, that number will get to zero.
Reaching a point where Tesla’s Robotaxi is driverless will be another significant milestone for the company and its path to fully autonomous ride-sharing.
Eventually, Tesla will roll out these capabilities to consumer-owned vehicles, offering them a path to generate revenue as their car operates autonomously and completes rides.
For now, Tesla is focusing on perfecting the area of Austin where it is currently offering driverless rides for just $4.20 to a small group of people.
