SpaceX fires up redesigned Crew Dragon as NASA reveals SuperDraco thruster “flaps”
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.”
NASA, November 13th, 2019
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.
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.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.
Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”
The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.
Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.
| Configuration | Seats | 0 to 60 mph |
|---|---|---|
| Performance | 2 | under 1.6 s |
| Thrust | 2 | under 0.9 s |
| Rocket | 1 | under 0.59 s |
Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.
Every car on the road today is limited by one thing: tire grip
Roadster’s thruster system generates 4–5x the force the tires can.
More force on the same mass means significantly better acceleration – physics does the rest https://t.co/zdPRT2aKwZ

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store
Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.
Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.
The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.
The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.

There are far more purchasing websites than just Amazon!

The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.
The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.
The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.
Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.
So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
