On February 16th, the European Space Agency (ESA) held the European Space Summit in Toulouse, France, offering European Space Agency leaders and European Union (EU) member states an opportunity to discuss the present and future of European spaceflight.

The central idea circulating the summit was evident: Europe wants to reassert itself as a global leader in space exploration. While ESA and member states continue to make exceptional contributions to robotic space exploration and – to a lesser degree – rocketry, leaders at the summit believe that there is still a large amount of untapped potential within the European space industry. ESA hopes to fill these gaps while tackling the societal, economic, and security challenges that come along with it. The ESA’s goal is to grow as a space fairing nation and compete side by side with the United States, Russia, and China on all fronts – including the possible creation of their own domestic human spaceflight program.

ESA Director-General Josef Aschbacher was encouraged to speak on the subject, stating that “I am very happy to accept President Macron’s proposal to establish a high-level advisory group on ‘human space exploration for Europe’.” “This decision will shape what Europe will look like in the decade to come. We have to involve experts from all walks of life and mainly from non-space, for example, historians, economists, geopolitical experts, explorers on Earth, and philosophers to fully grasp all its implications and help us take [sic] the right decision.”

Organizations such as the European Association of Space Explorers (ASE) have strong opinions on the future of the European Space Agency. The ASE represents the over 45 European astronauts and cosmonauts who have been flying to space since 1978 – including several ESA astronauts that most recently flew to and from the Internation Space Station on SpaceX’s Falcon 9 rocket and aboard Crew Dragon.

Released in a three-page manifesto titled, “EUROPEAN ASTRONAUTS’ MANIFESTO ON THE OCCASION OF THE EUROPEAN SPACE SUMMIT”, the organization expressed its passion for human spaceflight and wrote to encourage the ESA to further develop a program that might one day allow the European Union to launch its own astronauts.

“A Europe that projects itself as a leading society must have the capabilities to set its own goals, and to decide for itself how far it wants to go in space exploration, united in our European values,” the document stated. “We now have a unique window of opportunity to accelerate and become a fully recognized partner of the global space endeavor.” An advisory group has been put together by the ESA to further explore these possibilities and is set to report back to the ESA on their findings at the next ESA Council of Ministers held in November 2022.

“Between now and summer, we want to come up with more specific European targets and ambitions for manned space travel,” he said through an interpreter. “We need to know what our priorities are, have the data to back it up and prepare the choices we are going to take for the November [ESA] ministerial meeting.”, stated Aschbacher. ESA has repeatedly attempted to develop its own crewed spacecraft in the past, including the “Crew Rescue Vehicle” (one variant shown in the header image), Crew Space Transport System, and Hermes spaceplane.

Among the conversations of human spaceflight, the summit also revealed additional initiatives the ESA plans to focus on as they further develop a more independent space program. 

The ESA presented three “accelerators” or objectives that they aim to focus on while ramping up their space program. “Space for a Green Future”, “Rapid and Resilliant Crisis Response”, and “Protection of Space Assets”. According to the ESA, the three programs are described as the following:

“Space for a Green Future” aims to use data derived from Earth observation satellites to help Europe act to mitigate climate change and to support reaching a carbon-neutral economy by mid-century. 

“Rapid and Resilient Crisis Response” seeks to better use space data, cognitive cloud computing, and intelligent interconnectivity in space to support those in charge to provide the vital responses to crises on Earth.

“Protection of Space Assets” will contribute to preventing damage to the European space infrastructure and avoid disruption to its economically vital infrastructures such as power supplies and communications links due to space weather conditions.

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.

  • Road use: Tesla notes the car is not approved for public road use, and that Rocket isn’t 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!
