A martian rock has lots of carbon on it, and it's not clear why

A martian rock has lots of carbon on it, and it's not clear why

NASA’s Perseverance rover has spent five years traversing Jezero Crater looking for the chemical leftovers of whatever processes were at work on Mars billions of years ago. The rover has found organic carbon, but it has mostly been inside rocks that had to be drilled or abraded to expose it. But now, at an outcrop on the edge of an ancient river channel named Neretva Vallis, Perseverance detected complex macromolecular carbon sitting right on the rock’s surface.

“To our knowledge, that’s the shallowest detection of organic matter on Martian surface to date,” said Ashley E. Murphy, a researcher at the Planetary Institute in Tucson, Arizona, and lead author of the study of the rock, which was found at a site called Bright Angel. On Earth, this much macromolecular carbon usually suggests a biological origin. But to learn what this Bright Angel carbon is and where it came from, we might need to bring samples back to Earth.

Carbon on the rocks

The detection of Bright Angel carbon came from SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals), a UV Raman spectrometer fitted on Perseverance’s robotic arm. SHERLOC fires a deep-ultraviolet laser at a target and reads the light that bounces back at shifted energies, a signal that enables scientists to identify specific molecular bonds.

Rocket Report: Indian startup nears first launch; SpaceX's millenary milestone

Rocket Report: Indian startup nears first launch; SpaceX's millenary milestone

Welcome to Edition 9.01 of the Rocket Report! Back in January, I wrote about the 20 launches and landings we were most excited about in 2026. The list included things that were, at the time, officially scheduled to occur this year. I also gave my own view of the probability of each of these events actually happening before December 31. Halfway through the year, we can only count one of the events as completed, and that was NASA's Artemis II mission in April. Many are now scheduled for next year, proving again that delays are a constant in the space industry. A couple of them—such as the launch of NASA's Roman Space Telescope—do appear to be on track to happen soon.

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Swift Boost Mission reaches orbit. A pioneering commercial mission to reboost the orbit of NASA's Swift astronomy satellite launched early Friday after attempts earlier in the week were thwarted by bad weather and a technical issue. The Link servicing satellite developed by Katalyst Space Technologies soared to orbit on the tip of a Northrop Grumman Pegasus XL rocket that dropped from the belly of a modified L-1011 jetliner over the remote Pacific Ocean. Mission managers called off two launch attempts Tuesday and Wednesday due to poor weather around the L-1011's staging base on Kwajalein Atoll in the Marshall Islands. On Thursday, "a launch vehicle issue temporarily prevented teams from deploying the rocket" after takeoff of the L-1011.

Inside the Luddite festival harnessing Gen Z’s rage against Big Tech

Inside the Luddite festival harnessing Gen Z’s rage against Big Tech

On a Sunday evening in the middle of Tompkins Square Park in New York City’s East Village, hundreds of people gather in front of a giant papier-mâché face of a woman wearing a crown. She’s the backdrop of a play, her body made up of curtains that look like a dress but serve a dual purpose, allowing actors to scurry on and offstage.

I’m here to watch a performance called “Luddite Recreations,” which is a history of the Luddite movement—a group of artisans and textile workers who resisted the adoption of machines during the early years of the Industrial Revolution in England and whose resistance to being displaced from their work was met with violence by the British monarchy.

It’s one of the opening events of the Summer of Ludd, a weeklong series of talks and activities like how to flirt and date offline, mending, and learning to fight against data centers, all focused on getting people off their phones and into community.

Despite the darkness, I still see signs of hope in America

Despite the darkness, I still see signs of hope in America

The last time America celebrated a big anniversary, I was all of three years old. Even so, I retain a few fuzzy memories from a sunny summer afternoon in small-town Michigan: climbing on a cannon in front of the courthouse, watching a parade, and seeing my dad, a veteran and Centreville city councilman, giving a short talk about democracy.

Only later would I realize the significance of the date: July 4th, 1976, America’s bicentennial.

America was imperfect and inconsistent in its approaches to "freedom," but the country had done some big, difficult things in recent decades. We had led the charge to roll back the tide of fascism and Holocaust during World War II. We had begun to confront internal demons through the nonviolent activism of the civil rights movement. And, critically for my own life trajectory, we had landed on the Moon.

Visiting the stars (and planets, and telescopes) in VR

Visiting the stars (and planets, and telescopes) in VR

Having a computer strapped to my face for 40 minutes was one reason to feel a little sweaty. But the tour of the Universe I had just received in virtual reality—including visits to the near vicinity of the Sun, the giant black hole at the center of our galaxy, and a hellscape of an exoplanet 41 light-years distant—provided another excuse for sensing some heat.

Smithsonian Starstruck: An Immersive Experience is a 40-minute astronomy walk-through. It debuted in Washington, DC, in May with solo adult tickets now ranging from $29 to $35 and group tickets for four or more starting at $18 each (all now discounted by 15 percent); it will also open in Denver, Orlando, Florida, and San Antonio, Texas, later this year. I stopped by on a Monday in June to take it in.

After some onboarding that included setting such preferences as closed captioning and signing a waiver, I had enough time to sit on a bench next to the exhibit space (which has hosted other VR experiences) to enjoy watching another attendee with a VR headset blurt out, “Oh my God!”

Wing Commander IV and the FMV future that never quite was

Wing Commander IV and the FMV future that never quite was

If I had to pick a chunk of the 1990s that feels the most 90s-ish to me, it'd be the two-year stretch between 1996 and 1997. 1996 saw me graduating from high school and starting college; 1997 saw me meeting my future wife and falling in love. While I tried to figure out how to navigate the University of Houston's still mostly pre-digital first-semester registration process (we had to sign up for classes over the phone, with touch-tone buttons, like cavemen!), the larger world kept turning in ways that felt inevitable and good and right. The Cold War was in the rearview mirror—how could we ever have been so worried about nuclear annihilation just a few years before? Russia was a friendly bear presided over by everyone's favorite drunk uncle, and things would obviously keep getting better, right?

Equally obvious, at least according to gaming tastemakers like Ken and Roberta Williams or Chris Roberts, was the idea that computer games from here on would blend together the best of what Hollywood and Silicon Valley had to offer, and the resulting "Silliwood revolution" would blast us forever into the world of fully interactive entertainment. Movies and games would blend together, and neither would be the same ever again! No longer would people sit in theaters just watching movies—audiences would get to choose how the film ended! And on the computer side of things, gone would be the days of lame graphics and clunky hand-drawn art—games would have big-name actors, big-budget sets, and huge special effects!

And if 1996–1997 was the high water-mark of the 90s for me, then the game that most matched that high water-mark was Wing Commander IV: The Price of Chris Roberts Having Full Creative Control—erm, I mean, Wing Commander IV: The Price of Freedom.

Newly discovered PamStealer isn't your typical macOS malware

Newly discovered PamStealer isn't your typical macOS malware

Researchers have found a never-before-seen piece of macOS malware that combines a series of clever tradecraft to infect Macs with stealthy, custom-developed credential-stealing code.

The malware is delivered in two stages. The first is distributed in a disk image that masquerades as Maccy, a clipboard manager for Macs. It’s compiled as AppleScript that is notable for the way it delivers the second stage. The malware is named PamStealer because the Rust-written infostealer uses the Pluggable Authentication Modules interface built into macOS to validate the target’s login password before sending it to an attacker-controlled server.

A quieter execution chain

The use of both disk image and AppleScript is common in malware for Macs. More unusual is the way PamStealer combines them to gain stealth. When the AppleScript is double-clicked, it’s opened in the macOS Script Editor, where the malicious functionality is buried deep within the file.
