Not quite halfway through a six-year sojourn through the Solar System, a NASA spacecraft used a close encounter with Mars last week as a dress rehearsal for its arrival at the Solar System's largest metal asteroid in 2029.
The Psyche mission launched more than two-and-a-half years ago, in October 2023, from Kennedy Space Center, Florida, to kick off a journey of some 2.2 billion miles (3.6 billion km) to reach its unexplored namesake, the asteroid Psyche. The robotic research mission got an initial lift from a powerful SpaceX Falcon Heavy rocket. It uses plasma engines to gradually build up the impulse needed to reach its destination in the asteroid belt, between the orbits of Mars and Jupiter.
A flyby of Mars last Friday gave the spacecraft its most significant boost since launch. Navigators at NASA's Jet Propulsion Laboratory in California set up the spacecraft for a course taking it 2,864 miles (4,609 km) from the Martian surface, well above the planet's tenuous atmosphere. Psyche used Martian gravity like a slingshot to gain enough speed to reshape its orbit around the Sun, putting the probe on a path to intercept its asteroid target.

No doubt buoyed by all the positive advance reviews on social media, Amazon MGM Studios has released one last trailer for Masters of the Universe, and it comes in strong with the 1980s nostalgia, chock-full of Easter eggs to delight Ars readers of a certain age.
Directed by Travis Knight (Bumblebee, Kubo and the Two Strings), the film is a reboot of sorts of the He-Man and the Masters of the Universe series, its spinoff, She-Ra: Princess of Powers, and the many, many other offshoots of this hugely popular Mattel franchise. Per the official premise:
In Masters of the Universe, Director Travis Knight brings the legendary franchise back to the big screen in this epic live-action adventure. After being separated for 15 years, the Sword of Power leads Prince Adam (Nicholas Galitzine) back to Eternia where he discovers his home shattered under the fiendish rule of Skeletor (Jared Leto). To save his family and his world, Adam must join forces with his closest allies, Teela (Camila Mendes) and Duncan/Man-At-Arms (Idris Elba), and embrace his true destiny as He-Man — the most powerful man in the universe.
In addition to Galitzine, Mendes, Elba, and Leto, the cast includes Alison Brie as Professor Evelyn Powers (aka Evil-Lyn); Morena Baccarin as the Sorceress of Castle Grayskull; Jóhannes Haukur as Malcolm/Fisto; James Purefoy and Charlotte Riley as King Randor and Queen Marlena; Sasheer Zamata as Suzie, Adam/He-Man’s BFF on Earth; Kristen Wiig as Roboto; James Wilkinson as Mekaneck; Jon Xue Zhang as Ram-Man; Kojo Attah as the bounty hunter Tri-Klops; Sam C. Wilson as cyborg/weapons expert Kronis/Trap-Jaw; Hafþór Júlíus Björnsson as Goat Man; Jóhannes Haukur Jóhannesson as Malcolm / Fisto; Robert Towers as Karg; and Christian Vunipola as Adam's roommate on Earth, Hussein.

At a star-studded event that closed downtown Los Angeles' Sixth Street Viaduct last night, Mercedes and AMG unveiled the next generation of performance electric vehicles. The new four-door GT Coupe arrives in the midst of a pivotal period, the result of an almost experimental process that seems to take two steps forward and one step back quite regularly. In many ways, the all-electric AMG leaves previous plans in the past by effectively bringing the record-setting Concept AMG GT XX to series production, with many firsts for Mercedes supporting the abandonment of internal combustion power, including new axial motors from YASA and F1-derived battery cells.
Fittingly, then, Mercedes brought out its F1 team’s personnel, as George Russell presented the new car while Toto Wolff and Kimi Antonelli watched from the makeshift grandstands. Hollywood celebs ran the gamut, from Brad Pitt—who drove one GT onto the bridge—to Jacob Elordi and Kevin Hart, while Blink 182 played a surprisingly sarcastic mini set. All of the above may mean less to potential GT buyers than performance metrics and pricing when the 2027 model year comes along, but it only serves to prove just how big a deal Mercedes-AMG believes this will be.
In person, the new GT bears almost no resemblance to any of Benz’s prior EVs. No more bulbous, nautical EQS shapes or minorly smoothed over boxy G-Wagen aesthetic. The new design is more aided by digital renderings and iterative algorithms, especially the jutting front grille, reclined headlights, and Kamm-tail rear end—a bit of Aston Martin fore and aft. From the profile view, the proportions fit somewhere between a Porsche Panamera or Taycan, low-slung and slippery for ideal aerodynamic efficiency.

It's not an ideal time to be buying a new PC or doing a major upgrade. Price crunches for RAM and storage chips are making all kinds of components more expensive, and the shift to DDR5 in modern Intel and AMD CPUs means that a lot of people would need to pay money to replace their current DDR4 kits if they wanted to step up to a significantly newer, faster CPU and motherboard.
AMD may have something on the horizon for people who are looking to stretch their current PC (and its DDR4 RAM kit) just a little further. Leaks spotted by Tom's Hardware point to the existence of an "AMD Ryzen 7 5800X3D 10th Anniversary Edition," a re-release of a 4-year-old out-of-circulation CPU that might nevertheless be an upgrade for people with older Ryzen CPUs in Socket AM4 motherboards.
The "X3D" in the chip's name signifies that it comes with 64MB of extra L3 cache stacked on top of the main CPU die, bringing the total amount of L3 cache to 96MB. Workloads that benefit from extra cache—including most games—will perform much better on the 5800X3D than they do on the vanilla Ryzen 7 5800X.

Google on Wednesday published exploit code for an unfixed vulnerability in its Chromium browser codebase that threatens millions of people using Chrome, Microsoft Edge, and virtually all other Chromium-based browsers.
The proof-of-concept code exploits the Browser Fetch programming interface, a standard that allows long videos and other large files to be downloaded in the background. An attacker can use the exploit to create a connection for monitoring some aspects of a user’s browser usage and as a proxy for viewing sites and launching denial-of-service attacks. Depending on the browser, the connections either reopen or remain open even after it or the device running it has rebooted.
The unfixed vulnerability can be exploited by any website a user visits. In effect, a compromise amounts to a limited backdoor that makes a device part of a limited botnet. The capabilities are limited to the same things a browser can do, such as visit malicious sites, provide anonymous proxy browsing by others, enable proxied DDoS attacks, and monitor user activity. Nonetheless, the exploit could allow an attacker to wrangle thousands, possibly millions, of devices into a network. Once a separate vulnerability becomes available, the attacker could use it to then compromise all those devices.

President Donald Trump’s latest pitch for using taxpayer dollars to secure his White House ballroom featured a militarized building—including a rooftop hardened against drone strikes and a “drone port” that could potentially house military drones.
The remarks came on May 19 as Trump gave reporters a personal tour of the ballroom project that has already involved the demolition of the White House mansion’s East Wing. The president spoke of installing a rooftop drone base “for unlimited numbers of drones” operated by the US military as a “drone port that would protect all of Washington,” according to Reuters. He also highlighted a ballroom roof made from “impenetrable steel” that would supposedly be “drone-proof” against potential drone strikes.
To pay for such measures, Trump has been urging Republican lawmakers in the US Congress to approve $1 billion in taxpayer funding to provide a wide variety of “security adjustments and upgrades” for his ballroom project. The taxpayer-backed security enhancements would be separate from the $400 million construction cost for the ballroom project that has been funded by private donors, including companies such as Amazon, Apple, Coinbase, Comcast, Google, HP Inc., Lockheed Martin, Meta, Micron Technology, Microsoft, Palantir, Ripple, and T-Mobile.
