SpaceX’s Falcon 9 rideshare program secures its first customer
On August 22nd, spaceflight startup Momentus Space and launch heavyweight SpaceX announced the first public launch contract to fall under the umbrella of the latter company’s recently-announced Satellite Rideshare Program.
Meant to provide a reliable, consistent, and affordable form of shuttle-like access to orbit, SpaceX’s rideshare program will – pending demand – involve no less than one dedicated Falcon 9 launch per year, capable of placing 15+ metric tons (33,000+ lbs) into low Earth orbit. Although SpaceX’s rideshare proposal is far from revolutionary, the company’s contract with Momentus Space appears to be more than a basic launch service agreement, potentially opening doors for far more flexible rideshare launches in the future.
Since its November 2017 founding, Momentus Space has been able to put money where its mouth is far more so than any comparable space tug hopeful, of which there are several. The concept that has helped Momentus raise nearly $34M in just 1.5 years is relatively simple: build a spacecraft whose sole purpose is to propel other spacecraft to their final orbit(s).
Known as a space tug, the concept is about as old as practical spaceflight itself, and interest in actually developing the concept from paper to hardware has grown exponentially in the last 5-10 years, thanks in large part to an unprecedented boom in commercial spaceflight activity. Applied more specifically, modern efforts like Momentus tend to have ambitious goals couched behind much more achievable (and marketable) concepts.
Momentus Space’s first goal is to bridge the gap between the low cost of smallsat rideshare missions on large rockets and the convenience of smallsat launches on much smaller rockets by building lightweight, simple, and cheap orbital tugs. The first tug the company wants to field is called Vigoride and will measure approximately 2ft x 2ft (0.4m²) and weigh just 80 kg (175 lb) fully fueled. If launched to a 600 km (370 mi) sun-synchronous orbit (SSO), Vigoride will be able to deliver as much as 220 kg (~500 lb) to a final circular orbit of ~1500 km (930 mi) or place 250 kg (550 lb) of satellites into 10+ separate orbits.
Water plasma rockets (!?)
By far the most innovative and potentially revolutionary aspect of Momentus’ plans is its custom propulsion system of choice: water plasma rockets. In simple terms, Momentus space tugs would quite literally turn water and sunlight into a method of in-space propulsion that can offer both moderate efficiency and relatively high thrust. Using solar arrays, the space tug would charge batteries that would then power an extremely high-power microwave electrothermal thruster (MET).
In the case of Momentus, the exotic form of propulsion uses microwaves to almost instantaneously turn liquid water into plasma, an ionized, electrically-charged gas that can then be directed with a magnetic nozzle to produce thrust. Aside from the decent performance it offers, water-based MET allows a given satellite to completely avoid heavy pressure vessels, doesn’t require extremely high voltages, and uses a fully non-toxic propellant (water).
The fact that pure water is so incredibly benign, non-toxic, and accessible opens up a realm of possibilities. Momentus already has plans to launch Vigorides from the International Space Station, and that could eventually expand into actual in-space reuse in which water-powered satellites might dock with the ISS to load more water and pick up new payloads.
In the case of SpaceX, it appears that the company has inked a more two-way agreement with Momentus, in the sense that prospective customers of SpaceX’s Satellite Rideshare Program might actually be able to arrange for their satellites to be included on Vigoride. Vigoride would then be able to deliver each payload – up to 250 kg worth – to its own orbit, potentially far more convenient than simply being kicked off at a lone orbital bus stop. As Momentus matures its technology and moves from Vigoride to Vigoride Extended and beyond, a partnership with SpaceX’s Satellite Rideshare Program could grow into an almost unbeatable turnkey option for the smallsat industry.
Momentus took its first major step towards building capable and marketable space tugs in July 2019 when the company launched X1, its first orbit-worthy satellite prototype. Although the company has been dead silent as to the actual status of that prototype, even a failure would still serve as an invaluable learning opportunity, even if it would be an inconvenient setback. Vigoride’s first test flight was planned as early as late 2019, although the status of that schedule is uncertain.

Man credits Grok AI with saving his life after ER missed near-ruptured appendix
The AI flagged some of the man’s symptoms and urged him to return to the ER immediately and demand a CT scan.
A 49-year-old man has stated that xAI’s Grok ended up saving his life when the large language model identified a near-ruptured appendix that his first ER visit dismissed as acid reflux.
After being sent home from the ER, the man asked Grok to analyze his symptoms. The AI flagged some of the man’s symptoms and urged him to return immediately and demand a CT scan. The scan confirmed that something far worse than acid reflux was indeed going on.
Grok spotted what a doctor missed
In a post on Reddit, u/Tykjen noted that for 24 hours straight, he had a constant “razor-blade-level” abdominal pain that forced him into a fetal position. He had no fever or visible signs. He went to the ER, where a doctor pressed his soft belly, prescribed acid blockers, and sent him home.
The acid blockers didn’t work, and the man’s pain remained intense. He then decided to open a year-long chat he had with Grok and listed every detail that he was experiencing. The AI responded quickly. “Grok immediately flagged perforated ulcer or atypical appendicitis, told me the exact red-flag pattern I was describing, and basically said “go back right now and ask for a CT,” the man wrote in his post.
He copied Grok’s reasoning, returned to the ER, and insisted on the scan. The CT scan ultimately showed an inflamed appendix on the verge of rupture. Six hours later, the appendix was out. The man said the pain has completely vanished, and he woke up laughing under anesthesia. He was discharged the next day.

AI doctors could very well be welcomed
In the replies to his Reddit post, u/Tykjen further explained that he specifically avoided telling doctors that Grok, an AI, suggested he get a CT scan. “I did not tell them on the second visit that Grok recommended the CT scan. I had to lie. I told them my sister who’s a nurse told me to ask for the scan,” the man wrote.
One commenter noted that the use of AI in medicine will likely be welcomed, stating that “If AI could take doctors’ jobs one day, I will be happy. Doctors just don’t care anymore. It’s all a paycheck.” The Redditor replied with, “Sadly yes. That is what it felt like after the first visit. And the following night could have been my last.”
Elon Musk has been very optimistic about the potential of robots like Tesla Optimus in the medical field. Provided that they are able to achieve human-level articulation in their hands, and Tesla is able to bring down their cost through mass manufacturing, the era of AI-powered medical care could very well be closer than expected.

Tesla expands Model 3 lineup in Europe with most affordable variant yet
The Model 3 Standard still delivers more than 300 miles of range, potentially making it an attractive option for budget-conscious buyers.
Tesla has introduced a lower-priced Model 3 variant in Europe, expanding the lineup just two months after the vehicle’s U.S. debut. The Model 3 Standard still delivers more than 300 miles (480 km) of range, potentially making it an attractive option for budget-conscious buyers.
Tesla’s pricing strategy
The Model 3 Standard arrives as Tesla contends with declining registrations in several countries across Europe, where sales have not fully offset shifting consumer preferences. Many buyers have turned to options such as Volkswagen’s ID.3 and BYD’s Atto 3, both of which have benefited from aggressive pricing.
By removing select premium finishes and features, Tesla positioned the new Model 3 Standard as an “ultra-low cost of ownership” option of its all-electric sedan. Pricing comes in at €37,970 in Germany, NOK 330,056 in Norway, and SEK 449,990 in Sweden, depending on market. This places the Model 3 Standard well below the “premium” Model 3 trim, which starts at €45,970 in Germany.
Deliveries for the Standard model are expected to begin in the first quarter of 2026, giving Tesla an entry-level foothold in a segment that’s increasingly defined by sub-€40,000 offerings.
Tesla’s affordable vehicle push
The low-cost Model 3 follows October’s launch of a similarly positioned Model Y variant, signaling a broader shift in Tesla’s product strategy. While CEO Elon Musk has moved the company toward AI-driven initiatives such as robotaxis and humanoid robots, lower-priced vehicles remain necessary to support the company’s revenue in the near term.
Reports have indicated that Tesla previously abandoned plans for an all-new $25,000 EV, with the company opting to create cheaper versions of existing platforms instead. Analysts have flagged possible cannibalization of higher-margin models, but the move aims to counter an influx of aggressively priced entrants from China and Europe, many of which sell below $30,000. With the new Model 3 Standard, Tesla is reinforcing its volume strategy in Europe’s increasingly competitive EV landscape.

Tesla FSD (Supervised) stuns Germany’s biggest car magazine
FSD Supervised recognized construction zones, braked early for pedestrians, and yielded politely on narrow streets.
Tesla’s upcoming FSD Supervised system, set for a European debut pending regulatory approval, is showing notably refined behavior in real-world testing, including construction zones, pedestrian detection, and lane changes, as per a recent demonstration ride in Berlin.
While the system still required driver oversight, its smooth braking, steering, and decision-making illustrated how far Tesla’s driver-assistance technology has advanced ahead of a potential 2026 rollout.
FSD’s maturity in dense city driving
During the Berlin test ride with Auto Bild, Germany’s largest automotive publication, a Tesla Model 3 running FSD handled complex traffic with minimal intervention, autonomously managing braking, acceleration, steering, and overtaking up to 140 km/h. It recognized construction zones, braked early for pedestrians, and yielded politely on narrow streets.
Only one manual override was required when the system misread a converted one-way route, an example, Tesla stated, of the continuous learning baked into its vision-based architecture.
Robin Hornig of Auto Bild summed up his experience with FSD Supervised with a glowing review of the system. As per the reporter, FSD Supervised already exceeds humans with its all-around vision. “Tesla FSD Supervised sees more than I do. It doesn’t get distracted and never gets tired. I like to think I’m a good driver, but I can’t match this system’s all-around vision. It’s at its best when both work together: my experience and the Tesla’s constant attention,” the journalist wrote.
Tesla FSD in Europe
FSD Supervised is still a driver-assistance system rather than autonomous driving. Still, Auto Bild noted that Tesla’s 360-degree camera suite, constant monitoring, and high computing power mark a sizable leap from earlier iterations. Already active in the U.S., China, and several other regions, the system is currently navigating Europe’s approval pipeline. Tesla has applied for an exemption in the Netherlands, aiming to launch the feature through a free software update as early as February 2026.
What Tesla demonstrated in Berlin mirrors capabilities already common in China and the U.S., where rival automakers have rolled out hands-free or city-navigation systems. Europe, however, remains behind due to a stricter certification environment, though Tesla is currently hard at work pushing for FSD Supervised’s approval in several countries in the region.
