Despite a global pandemic and Falcon 9’s first in-flight engine failure in almost eight years, NASA administrator Jim Bridenstine remains confident that SpaceX and the space agency are still on track for Crew Dragon’s astronaut launch debut.

For the third time in about a month, NASA has officially confirmed that SpaceX’s Crew Dragon ‘Demo-2’ mission – the company’s first astronaut launch ever – is still tracking towards a liftoff in May 2020. While there are several good reasons to expect further delays, Bridenstine acknowledged and discounted those pressing risks in an April 9th interview with Spaceflight Now, explicitly stating that “if [Demo-2 does] slip, it’ll probably be into June. It won’t be much.”

Excluding several minor to moderate technical risks that have popped up in recent weeks, this suggests that the NASA administrator is also confident that one of the biggest sources of imminent schedule uncertainty – closed-door paperwork completion and joint reviews – will actually be smooth sailing.

On March 2nd, 2019, Falcon 9 lifted off for the first time with SpaceX’s upgraded Crew Dragon spacecraft on its inaugural orbital launch. Known as Demo-1, the mission was ultimately a flawless success, with Dragon performing exactly as expected throughout launch, orbit-raising, space station rendezvous, docking, departure, deorbit, reentry, and splashdown operations.

As Crew Dragon’s only orbital launch and space station docking, it also serves as the best and only glimpse into how long the more nebulous review and paperwork aspects of launch preparation can take. For Demo-1, Falcon 9 and Crew Dragon rolled out to Launch Pad 39A and completed a successful static fire on January 24th, 2019. The mission was then scheduled for launch no earlier than (NET) February 23rd and wound up being pushed back another week to March 2nd. In almost every case, Falcon 9 and Falcon Heavy launch less than a week after a successful preflight static fire and do not attempt a static fire until a given rocket and payload are both ready to go.

If there were technical challenges that lead to that six-week delay between Crew Dragon’s Demo-1 static fire and launch, they have never been broached publicly, making it more likely that NASA spent at least a month simply finishing up final paperwork and reviews. Hopefully, that substantial gap was mainly due to the fact that it was the first time NASA and SpaceX had to work together to launch Crew Dragon.

For Crew Dragon’s second Falcon 9 launch, successfully completed on January 19th, 2020, the rocket wrapped up its static fire test on January 11th — a major improvement compared to Demo-1. That suborbital In-Flight Abort (IFA) test isn’t directly comparable to Crew Dragon’s orbital launch debut, but it does encourage at least a little confidence that Demo-1’s six-week review period was an outlier.

Thankfully, Bridenstine says that all major Crew Dragon issues have been effectively closed out or are very close to closure as of April 2020. A SpaceX contractor was recently forced to prematurely drop a Crew Dragon parachute test vehicle on March 25th, destroying the mockup capsule before it could complete two final tests. The NASA administrator now says that all parties have agreed to complete those tests with a different mockup and will use a C-130 cargo plane instead of a helicopter.

By design, Crew Dragon Demo-2 astronauts Bob Behnken and Doug Hurley are likely about as insulated as one can get from the coronavirus pandemic. (SpaceX)

Bridenstine is also confident that the coronavirus pandemic – hampering almost all forms of industry in every afflicted country – will also have little to no impact on Crew Dragon’s astronaut launch debut schedule. NASA and SpaceX have put in place strict new rules and changed a number of procedures to further mitigate risk, helped by the fact that astronaut launches to the International Space Station (ISS) already operate with cleanliness and disease prevention as a major priority.

Finally, the NASA administrator also stated that SpaceX’s March 18th in-flight engine failure was “not going to impact our commercial crew launch,” confirming that SpaceX already has “a really good understanding of” what went wrong. Most likely, this means that Falcon 9 B1048’s stumble was directly related to the fact that the booster was flying for the fifth time – a first for a SpaceX rocket and orbital-class rocket boosters in general. Crew Dragon Demo-2 will be Falcon 9 booster B1058’s first launch.

Ultimately, while there are certainly good reasons to remain skeptical of NASA’s increasingly frequent assurances that Crew Dragon’s astronaut launch debut remains on track for late-May or June 2020, there are at least as many good reasons to stay confident.

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.


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.

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.

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!
