SpaceX a bastion of independent US, European spaceflight amid Russian threats

Published

on

Russia has invaded Ukraine without provocation, triggering a series of diplomatic responses – sanctions in particular – that recently culminated in the aggressor deciding to cut ties with Europe on a number of cooperative spaceflight projects.

Dmitry Rogozin, director of Russia’s national ‘Roscosmos’ space agency, went as far as implying that the country might respond to the West’s aerospace sanctions by ending its support of the International Space Station (ISS), a move that could cause the football-field-sized structure to gradually deorbit and reenter Earth’s atmosphere. Were it not for the existence of two extraordinarily successful NASA programs and SpaceX in particular, Russia’s response – which, today, reads like a child’s tantrum – could easily have been a grave threat with far-reaching consequences.

In response to sanctions after its unprovoked invasion, Russia announced that it was withdrawing support from Europe’s French Guinea Soyuz launch operations, effectively killing Arianespace’s Soyuz offering and potentially delaying several upcoming European launches indefinitely.

As a quick side note, it’s worth noting that ULA’s lack of readily available rockets and the fact that Arianespace is likely at least a year or more away from regular Ariane 6 launches means that SpaceX may be the only Western launch provider in the world capable of filling in the gap that Arianespace’s Soyuz loss will leave. Aside from pursuing Chinese launch services, which is likely a diplomatic non-starter, the only alternative to rebooking former European Soyuz payloads on SpaceX rockets is to accept one or even several years of expensive delays.

On the other half of the coin is the International Space Station. NASA signed its first major contract with SpaceX in 2008, awarding the company $1.6 billion (and up to $3.5 billion) to launch a dozen Cargo Dragon supply missions to the ISS. Aside from effectively pulling SpaceX back from the brink of dissolution, those funds also covered a large portion of the development of its Falcon 9 rocket and Dragon spacecraft and simultaneously funded Orbital Science’s (later Orbital ATK and now Northrop Grumman) Cygnus cargo spacecraft and Antares rocket.

Despite suffering two failures in 2014 and 2015, NASA’s Commercial Resupply Services (CRS) program has been an extraordinary success. Together, Cygnus (17) and Dragon (24) have completed 41 deliveries in the last 12 years, carrying more than 110 tons (~240,000 lb) of cargo to the ISS.

Out of sheer coincidence, on February 19th, mere days before Russia’s act of war, Northrop Grumman launched the first Cygnus spacecraft designed to help ‘re-boost’ (raise the orbit of) the International Space Station. Since NASA’s premature 2011 retirement of the Space Shuttle, that task has been exclusively conducted by a combination of Russian spacecraft and the station’s Russian Zvezda module. Without regular Russian re-boost support, the station would deorbit and be destroyed. In other words, if push came to shove, the ISS could very literally fail without direct Russian involvement. Rogozin’s threat, then, was that Russia might cease to support ISS re-boosting if sanctions went too far.

However, even while ignoring the fact that NASA itself actually paid for and owns the ISS Zvezda propulsion module and in light of the first Cygnus spacecraft upgraded with a re-boost capability berthing with the station the very same week of the invasion, Russia’s threat rang decidedly hollow. Further, if Cygnus weren’t available, it’s still difficult to imagine that SpaceX wouldn’t be able to quickly develop its own Dragon re-boost capability if asked to do so.

While re-boosting is crucial, the situation has also emphasized just how little leverage Russia now has over even more important aspects of the International Space Station. Were it not for the existence of SpaceX and NASA’s Commercial Crew Program (CCP), the situation could be even direr for Europe and the US. Despite some pressure from lawmakers to only award the CCP contract to Boeing, NASA ultimately selected Boeing and SpaceX to develop independent crew capsules capable of carrying US astronauts to and from ISS in 2014. Following a near-flawless uncrewed Crew Dragon test flight in 2019 and an equally successful crewed demo mission in 2020, SpaceX completed its first operational Crew Dragon launch in November 2020.

Since then, SpaceX has launched another two operational ‘crew rotation’ missions, meaning that the company has now singlehandedly supported all US astronaut launch and recovery operations for 16 months. Due in part to extensive mismanagement, Boeing’s Starliner spacecraft was nearly destroyed twice during its first catastrophic uncrewed test flight in December 2019. The spacecraft is still months away from a second attempt at that test flight, likely at least 9-12 months away from a hypothetical crewed test flight, and potentially 18+ months away from even less certain operational NASA astronaut launches. Further, though ULA CEO Tory Bruno claims that the company doesn’t need any support from Russia, all Atlas Vs – the rocket responsible for launching Starliner – depend on Russian-built RD-180 engines.

Further adding to the mire, even Cygnus is not immune. The first stage of the Antares rocket that mainly launches it is both built in Ukraine and dependent upon Russian Energomash RD-181 engines. Northrop Grumman only has the hardware on hand for the next two Cygnus-Antares launches, at which point the company will have to either abandon its NASA contract or find an alternative launch provider. Once again, SpaceX is the only US provider obviously capable of filling that gap on such short notice and without incurring major delays of half a year or more.

In fewer words, without SpaceX, NASA would still be exclusively dependent upon Russian Soyuz rockets and spacecraft to get its astronauts to and from the space station it spent tens of billions of dollars to help build. Even in a best-case SpaceX-free scenario, NASA might instead be dependent upon a rocket with Russian engines to launch its own astronauts. Needless to say, the presence of US astronauts on Russian launches and ULA’s use of Russian engines were already extremely sensitive issues after Russia ‘merely’ invaded Ukraine’s Crimea region in 2014.

It’s hard not to imagine that US and European responses to Russia’s aggression would have been weakened if NASA and ESA astronauts were still entirely dependent upon Russia to access the International Space Station. Further, in the same scenario, given its withdrawal from French Guinea, it’s also not implausible to imagine that Russia might have severely hampered or even fully withdrawn its support of Western access to the ISS.

Put simply, Crew Dragon – now a bastion of independent European and US human spaceflight in an age of extraordinary Russian recklessness – has arguably never been more important and SpaceX’s success never more of a triumph than they are today.

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!
