On November 13th, SpaceX revealed that a planned static fire test of a Crew Dragon’s powerful abort thrusters was completed without issue, a strong sign that the company has successfully redesigned the spacecraft to prevent a catastrophic April 2019 explosion from reoccurring.

Pending a far more extensive analysis, Wednesday’s static fire should leave SpaceX on track to perform Crew Dragon’s next major flight test before the end of 2019.

In an unexpected flourish of transparency, SpaceX and NASA published photos of the Crew Dragon capsule’s static fire test just a few hours after it was completed, an excellent sign that the ‘quick-look’ data analysis immediately following the test was extremely positive. Spaceflight Now was first to visually confirm that the test had occurred, publishing a photo that revealed a whitish cloud of smoke produced by the static fire around 3:15 pm EST (20:15 UTC).

Had a failure similar to the April 2019 explosion occurred, that cloud would have likely been tinged red by unburnt dinitrogen tetroxide (NTO) oxidizer, and the different appearance of November 13th’s exhaust cloud was seen as the first tentative sign that this static fire had gone more successfully.

Alongside photos of the SuperDraco thruster test published by NASA and SpaceX shortly after its conclusion, SpaceX confirmed that the test was completed without issue. Regardless of whether everything performed exactly as intended, this means that factory-fresh Crew Dragon capsule C205 made it through the test unscathed, likely securing SpaceX and NASA a large volume of uninterrupted telemetry data, as well as the hardware itself.

Just hours after C205’s static fire was completed, NASA published a detailed update, confirming that the tests were finished without any immediately apparent issues.

NASA described the test in much more detail than SpaceX, noting that it began with the ignition of two of Crew Dragon’s 16 Draco maneuvering thrusters, each performing two one-second burns. C205’s eight SuperDraco abort thrusters subsequently ignited and burned for a total of ~9 seconds to simulate required abort performance, followed by the reignition of two Draco thrusters immediately after SuperDraco cutoff.

Each capable of producing several dozen pounds of thrust, both Crew and Cargo Dragon use Draco thrusters to orient themselves in orbit, rendezvous with the International Space Station, and lower their orbits to reenter Earth’s atmosphere. Crew Dragon’s Draco thrusters are also designed to control its attitude during abort scenarios, stabilizing and flipping the spacecraft to prevent a loss of control and ensure proper orientation during emergency parachute deployment. The Draco firings during Crew Dragon’s November 13th static fire were meant to simulate that additional use-case.

Aside from verifying that SpaceX has successfully redesigned Crew Dragon to mitigate the failure mode that caused capsule C201’s catastrophic explosion in April 2019, the Draco static fires specifically mirrored the burns Crew Dragon C205 will need to perform to successfully complete its In-Flight Abort (IFA) test. As noted by NASA and SpaceX, with the static fire complete, both teams will now comb through the data produced, inspect Crew Dragon to verify its health and the performance of its redesigned high-flow pressurization system, and perform any necessary refurbishment.

SuperDraco’s mystery “flaps”

NASA’s post on Crew Dragon’s static fire revealed another thoroughly intriguing detail: the SpaceX spacecraft’s SuperDraco thrusters apparently have flaps! A bit of retroactive speculation suggests that SuperDracos are closed out with plugs of some sort to create a seal against the environment before Crew Dragon is rolled out to the launch pad. Perhaps, in the event of a SuperDraco ignition, SpaceX included actuating flaps as a method of resealing those thrusters prior to splashdown in the Atlantic Ocean.

“Immediately after the SuperDracos shut down, two Dracos thrusters fired and all eight SuperDraco flaps closed, mimicking the sequence required to reorient the spacecraft in-flight to a parachute deploy attitude and close the flaps prior to reentry. The full sequence, from SuperDraco startup to flap closure, spanned approximately 70 seconds.”

In retrospect, flaps (actuating covers) are an obvious explanation for the cutouts visible directly underneath each SuperDraco pod. (SpaceX)

Given that the obvious utility of those flaps appears to be extremely limited and their associated actuators have to survive the 9+ consecutive seconds of hellish conditions in the event of an actual abort, it seems like an excessively complicated system to include on Crew Dragon. Nevertheless, the ability to guarantee that SuperDracos are water-sealed before splashdown would almost without a doubt make Crew Dragon far easier to refurbish and reuse.

The SuperDraco flaps may also be a holdover from before propulsive Crew Dragon landings were canceled, although the use-cases for such a system still remain unclear. The flaps’ raison d’etre could even be as simple as preventing water intrusion that might otherwise cause Dragon to sink after splashdown.

The fact that Crew Dragon C201’s flaps appeared to be unchanged after launch and recovery suggests that they are more of a backup in the event that the abort thrusters have to be used. (NASA)

Regardless of why they exist, NASA indicates that SpaceX’s November 13th static fire proved that they worked exactly as expected, closing soon after the simulated abort burn to seal Crew Dragon against water intrusion. If NASA and SpaceX’s deep-dive inspections and data analysis uncover no red flags, it’s extremely likely that SpaceX will able to launch C205 for its In-Flight Abort test some 4-8 weeks from now.

If the IFA also goes as planned, Crew Dragon could be ready for its inaugural NASA astronaut launch as early as February or March 2020.

U.S. Secret Service in talks for armored cars with this automaker

The Secret Service says it’s still too early to know the future of a potential deal for these “highly-advanced vehicles.”

The U.S. Secret Service has entered early discussions with one automaker about the potential supply of armored SUVs, as announced by the agency this week.

In a post on X on Friday, the Secret Service account posted that Director Sean Curran recently met with executives from General Motors (GM) to discuss a potential next-generation of armored SUVs. The post also included photos of a Cadillac Escalade SUV, along with a few of executives talking about and showing off hardware from the next-gen platform.

“Countering evolving threats require us to constantly explore new innovations and improvements to our armored fleet of protective vehicles,” the account wrote in the post. “Director Sean Curran met with GM executives to discuss advancements that could benefit the next generation of armored SUVs.”

Currently, U.S. President Donald Trump typically utilizes an armored Chevy Suburban to get around, and the Secret Service said that it isn’t yet clear when such a next-gen “presidential limousine” could be added to the fleet. The news also comes after GM CEO Mary Barra met with Trump last week, reportedly also to discuss armored SUVs.

“We are too far out to speak to any specific costs or dates,” one Secret Service spokesperson told Reuters. “Our engineering, protective operations and technical security teams work for years to develop the state-of-the-art framework that is used to produce these highly advanced vehicles.”

Many in the thread also said that the Tesla Cybertruck could be a good option for the Secret Service, coming weeks after the U.S. State Department apparently canceled a potential $400 million Cybertruck order after it was widely reported on. State Department officials have since said that the figure listed in documents for the deal, which was first initiated under the Biden administration, were simply an estimate, and the Cybertruck has been removed from the broadly reported procurement list.

CEO Elon Musk also responded to the reports on X, suggesting that they were either misunderstood or false, noting that he was “pretty sure Tesla isn’t getting $400 million.”

“No one mentioned it to me, at least,” Musk added in the post.

The Cybertruck features a stainless steel exterior that has been touted by Tesla as being able to withstand bullets and other potential attacks. Tesla Cybertrucks have also been rolling out to some U.S. Police Departments in recent months, many featuring armored tune-ups from Unplugged Performance’s Up.Fit government and military fleet division.

Tesla Powerwalls to help expand Virtual Power Plant in Colorado

Colorado’s Virtual Power Plant program is about to get even bigger, with the help of Tesla’s Powerwalls.

Published

on

Tesla’s Powerwalls are set to help expand a Virtual Power Plant (VPP) program in Colorado, as an announcement this week notes that the company will be partnering with two local energy providers.

In a press release on Thursday, utility provider Xcel Energy and resource management company Itron announced a partnership with Tesla to help expand the existing VPP in Colorado, dubbed the Renewable Battery Connect program. Itron will integrate its IntelliFLEX platform with Tesla’s Powerwall management system, and the partners plan to increase the number of batteries that can be used during times of peak demand, as managed by Xcel.

The IntelliFLEX Aggregator Distributed Energy Resource Management System (DERMS) is designed to let energy providers localize the management of distributed batteries, utilizing a combination of residential battery storage, solar energy, electric vehicle (EV) chargers and other management systems to help balance grid energy more efficiently.

“Our Renewable Battery Connect program creates a new VPP in Colorado and we’re proud to work with Itron and Tesla, who have proven to be trusted industry partners and align with our goals to strengthen the energy grid while maintaining reliability and advancing renewable energy,” said Emmett Romine, Xcel’s VP of Customer Energy and Transportation Solutions. “This collaboration will deliver renewable, solar energy when our customers need it most.”

Itron also says the IntelliFLEX system currently helps facilitate around three million distributed energy resource devices for 30 different utilities across the U.S. The company also says the tool will give Xcel more power to manage customers’ residential batteries to help stabilize local grids.

“Integrating our IntelliFLEX solution with Tesla Powerwall demonstrates a shared vision with a leading technology partner who is at the forefront of creating electrification solutions,” said Don Reeves, SVP of Outcomes at Itron. “Through this collaboration, we are excited to bring new capabilities to Xcel Energy as they embark on its energy transition journey.”

Tesla’s Powerwall home batteries have been utilized in markets around the world, effectively letting owners store and sell stored energy back to the electrical grid in times of peak demand, outages, and other peak use cases. This kind of distributed battery system is being piloted or run in a number of U.S. states, including California, Texas, and Massachusetts, and in a few other countries and territories.

The company currently builds Powerwalls at its Gigafactory in Nevada, and the facility in November celebrated building over 1,000 of the home batteries in a single day as it continues to ramp production. In October, Tesla also said that it had over 100,000 Powerwalls participating in its VPP programs worldwide.

Tesla quietly added this extra Sentry Mode feature to deter vandals

Tesla’s Sentry Mode gets another feature, set to add an extra layer of security against vandalism.

Amidst increased vandalism events against Tesla’s vehicles in recent weeks, the company’s Sentry Mode has increasingly been in the spotlight as a deterrent for criminal activity. As part of an update to its website this week, Tesla has also revealed a subtle addition to the recording system that should help deter vandals caught in the act.

Tesla’s Sentry Mode on Cybertrucks will soon play music at the maximum volume when the vehicle’s cameras detect activity, as detailed on the company’s redesigned Cybertruck web page this week and initially spotted by Not a Tesla App. The detail was quietly added to the Cybertruck web page, as part of the larger Sentry Mode suite of features that lets owners check out the external cameras on their electric vehicles (EVs) even when away.

“Enable Sentry Mode to monitor your unattended vehicle or trailer, and automatically activate the alarm, increase the touchscreen brightness and play music at max volume if a threat is detected,” Tesla writes on the Cybertruck page.

The music feature could use the Cybertruck’s superhorn and external speaker to play the music outside the vehicle for an even louder response to potential threats, though it’s not clear at this point whether the added feature will utilize the external or internal speakers. The music feature is also not detailed on Tesla’s web pages for other vehicles at this point, though it would be surprising to see it only available on the Cybertruck given that Sentry Mode is available across the company’s entire lineup.

READ MORE ON TESLA SENTRY MODE: Tesla is about to ship a fix to a big Sentry Mode issue

Tesla details the features from Sentry Mode in its owner’s manuals as follows:

When enabled, your vehicle’s cameras remain powered on and ready to record suspicious activity around your vehicle when Cybertruck is locked and in Park. Think of Sentry Mode as an intelligent vehicle security system that alerts you when it detects possible threats nearby.

If a threat is detected or the vehicle sensors determine there is a lot of jerky movement like when getting towed or shaken, Sentry Mode:

    • Pulses the headlights.
    • Sounds the alarm.
    • Displays a message on the touchscreen that indicates cameras may be recording to inform individuals outside of the vehicles.
    • Alerts you of the alarm on the mobile app.
    • Saves footage of the event to a USB drive (if installed)

Earlier this week, CEO Elon Musk also said that Tesla was increasing security at the company’s stores, along with activating Sentry Mode on all vehicles at the company’s locations. Musk also said earlier this month that it could make its vehicles automatically honk at people who come near or touch the vehicle, which would take a similar approach to scaring off people potentially keying or otherwise vandalizing a Tesla.

Following a substantial uptick in protests and vandalism targeting Tesla’s vehicles in response to Musk’s recent actions at Trump’s inauguration and since with the newly created government efficiency, the Federal Bureau of Investigation (FBI) has begun looking into several of these incidents.

Additionally, President Donald Trump said that Tesla attacks would be categorized as “domestic terrorism,” even suggesting that some of those who have been recently arrested in these cases could be sent to prison camps in El Salvador, where the administration has recently been sending migrants.

“I look forward to watching the sick terrorist thugs get 20 year jail sentences for what they are doing to Elon Musk and Tesla,” Trump wrote in a post on his social media platform Truth Social. “Perhaps they could serve them in the prisons of El Salvador, which have become so recently famous for such lovely conditions!”
