SpaceX launches NASA mission to study black holes, dead stars, and more
SpaceX has successfully launched NASA’s Imaging X-ray Polarimetry Explorer telescope, paving the way for a unique aspect of black holes, a variety of dead stars, and other odd phenomena to be explored in unprecedented breadth and detail.
Marking the first time a NASA payload has launched on the fifth flight of a reused SpaceX rocket, Falcon 9 booster B1061 lifted off at 1am EST (06:00 UTC) to kick off the 330 kg (~730 lb) IXPE spacecraft’s journey to orbit. SpaceX’s workhorse rocket performed flawlessly. Just over eight minutes after liftoff, Falcon 9’s upper stage completed the first of two planned burns, entering a low parking orbit. About thirty seconds later, Falcon 9 B1061 stuck its fifth drone ship landing in 13 months, marking the end of another successful high-profile launch for the booster and ensuring that it will be able to complete many more such launches over the next few years.
The first portion of the launch completed, Falcon 9’s upper stage then coasted in orbit for about 20 minutes before ignited for one last (very expensive) burn to place IXPE in its desired orbit. Known as a plane or inclination change, the maneuver – especially when performed deep in a large gravitational well – is exceptionally expensive, requiring an unintuitively large amount of launch vehicle performance (known as delta-V). The reason: IXPE’s nominal orbit is almost exactly equatorial, which Falcon 9’s Cape Canaveral launch site is about 28.5 degrees north of.
Lowering that inclination after launch requires a very energetic maneuver. Before Falcon 9 beat it out for the launch contract, IXPE was expected to launch on Orbital ATK’s air-launched Pegasus XL rocket, which would have allowed IXPE to be launched at the equator. However, SpaceX ultimately submitted a bid to launch IXPE for just ~$50M – cheaper than its competitor despite the fact that Falcon 9 is more than 20 times larger and could potentially launch an entire Pegasus XL into orbit. However, while Falcon 9 is designed to launch almost 23 tons into orbit in an expendable configuration and more than 16 tons with booster and fairing recovery, it’s only capable of launching about 1-2 tons to IXPE’s desired combination of an equatorial inclination and a ~600 km (~370 mi) orbit.
Ultimately, Falcon 9 completed the inclination change without issue, marking the successful completion of its first equatorial launch ever and SpaceX’s 28th successful launch in 2021 alone. Unlike a significant majority of spacecraft, IXPE was launched directly into its operational orbit and will likely need just a few days to refine its position and a few weeks after that for ground controllers to verify the health of all its systems and deploy a 4m (`13 ft) long ‘boom’ needed to operate its unique telescope.
If or when everything is up and running, IXPE will spend a minimum of two years observing at least 50 of the weirdest objects and phenomena in the universe. While many of those objects can’t be directly imaged, IXPE’s goal is to analyze the polarization of X-rays – high-energy beams of radiation – they produce at sensitivities two orders of magnitude greater than any previous experiment. In theory, that should allow IXPE to put long-held laws of relativity and quantum physics to the test in some of the most extreme environments in the universe, including particularly exotic nebulae (giant gas clouds), black holes, and bizarre neutron stars (including lighthouse-like pulsars and magnetars – dead stars with magnetic fields strong enough to compress atoms into cylindrical rods and make the actual vacuum of space refract light like a crystal).

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.
