Blue Origin has unveiled a third stage called GS3 for its New Glenn rocket, designed to deliver satellite constellations directly to geostationary orbit and support heavy-lift missions to the Moon and deep space. The company also announced Northstar, a new methalox booster engine that it says produces 715,000 pounds of thrust while cutting mass by 30% and parts by 50% compared with the BE-4. Space.com reports: The new stage will be powered by one BE-7 engine, which the company developed for use on its Blue Moon spacecraft, one of the two private vehicles that NASA selected to be crewed lunar landers for its Artemis program. (The other is SpaceX's Starship.) Blue Moon landing missions won't need to launch on GS3-equipped New Glenn rockets, according to Blue Origin. But the third stage "can support sustained operations around the moon," the company wrote in today's blog post. "By delivering significant payload mass directly to trans-lunar injection (TLI), GS3 enables faster transit times while preserving propellant for on-orbit operations." And there's already demand for such services: Blue Origin also announced today that a government customer (which it did not name) has booked a GS3 mission to cislunar (Earth-moon) space, with launch targeted for 2028. And the company dropped yet more news today -- that it's working on a new first-stage engine, called Northstar. Like Blue Origin's other booster engine, the BE-4, Northstar burns liquid oxygen and liquid methane propellant, a combination known as methalox. But the new engine is more powerful and less complex. "Compared to the BE-4 engine, Northstar reduces mass by 30% and parts count by 50%, while increasing thrust from 640,000 to 715,000 pounds-force," Blue Origin said in a second blog post today. "Manufacturing advancements have also significantly shortened production timelines, enabling assembly in less than a day." Northstar went from program approval to development testing in just 11 months, according to the company. But today's update did not say when the new engine will fly for the first time.

The FAA announced today that it is finally phasing out floppy disks from air traffic control systems at more than 400 facilities. Engadget reports: They'll be replaced by a more modern system called Enterprise -- Information Display System (E-IDS), which is comprised of a digital display for relaying status information, updates and other alerts to air traffic teams. The FAA plans to have E-IDS installed in 435 sites by the end of 2028; the first five locations to receive the upgrades are the Atlantic City International Airport, Nashville International Airport and Greater Rochester International Airport, as well as data processing hubs in Atlanta and Salt Lake City.

An anonymous reader quotes a report from Scientific American: The Great Pacific Garbage Patch, an area in the Pacific Ocean where debris naturally accumulates, is full of tiny bits of plastic -- so full, in fact, that it seems to be changing the color of the ocean. [...] To better understand how microplastics may have influenced the ocean's color, [Daniel Koestner, a postdoctoral fellow at the University of Bergen in Norway] and his colleagues looked at 20 years of satellite data from the spot in the ocean with perhaps the most of plastic -- the Great Pacific Garbage Patch, a zone between Hawaii and California where trash trapped by ocean currents accumulates. Between 2002 and 2022, the researchers found, waters near the garbage patch have gotten brighter in both blue and green wavelengths compared with surrounding areas. The results, published in the journal Communications Earth & Environment on Thursday, don't yet prove that microplastics have directly brightened the ocean, the researchers emphasize, though their findings are backed up by lab experiments with microplastics. But without taking direct ocean samples, it's hard to know for sure what's causing the ocean's color to change. "We're still one step away from proving definitively that microplastics are causing the shift in color that that we're seeing," adds study co-author Shea Cheatham, a Ph.D. student also at the University of Bergen. "We just have to get in there [to the garbage patch] to verify." The hope is that detecting these color shifts could help identify other areas around the world where microplastics have accumulated.

Ubuntu has been at the forefront of replacing the traditional versions of basic tools like sudo with replacements written in Rust, but aside from worries about replacing battle-tested code with brand new, relatively untested code, there's new things to worry about it. As it turns out, sudo-rs, the Rust replacement for sudo, is intentionally incompatible with the classic version in dangerous ways, as Chris Siebenmann discovered to his dismay. Basically, the classic sudo supports the use of wildcards defined using square brackets, so that if you allow a user to run, say, /usr/sbin/exim -bp, without a password, they can run exim -bpa, exim -bpc, exim -bpr, or exim -bpu without having to supply a password. This allows for very specific, fine-grained access control, which is quite a nice capability to have if you're managing many systems and users. Sadly, sudo-rs intentionally does not support this, opting to only allow you to use the generic * wildcard. Worse yet, it doesn't really make this clear, either. ↫ Chris Siebenmann I do not really have words for this. The Rust sudo has apparently opted to keep the single most dangerous wildcard while disallowing all of the wildcards that allow one to be narrow and specific about what you're allowing, and it buries this at the end of a section that devotes a bunch of words to describing functionality it doesn't have and doesn't support, with absolutely nothing else in that section to say this (either up front or in the descriptions of how all the wildcards would work if sudo-rs supported them, which it doesn't). If you're going to replace such vital, core tools like sudo that god knows how many people rely on every single day, you better be damn sure you're feature-complete and can act as a drop-in replacement. If someone switches from sudo to doas, nobody expects the experience to be identical. However, if you're consistently being told that sudo-rs is a drop-in replacement and you shouldn't expect any disruptions, you better be able to make true on that promise. Ubuntu isn't some also-ran small hobby distribution, and its developers should act like it. What a clown show.

The second desktop environment release I've got for you today is LXQt 2.5.0. This new version excises its last LXDE dependency, and QTerminal and QTermWidget received considerable improvements, like new background image modes, a visual bell, support for OSC-8 hyperlinks, and more. There's a ton of smaller changes and improvements as well, but do note that due to a bug, 2.5.0 broke LXQt's Monitor Settings on X11. The project intends to fix this as quickly as possible and push a point release to address this issue.

It's desktop environment Thursday, as I've got two new releases for you today. First, Cinnamon, the desktop environment primarily associated with Linux Mint, has hit version 6.8. This version will officially ship with Linux Mint 27, scheduled for around Christmas of this year. Highlights of Cinnamon 6.8 include hibernation support via a Suspend action in the main menu, modern one-to-one trackpad gestures for both Wayland and Xorg sessions, support for the oo7 Secret Service provider, support for multiple instances in the Sound applet, and a more unified Network applet that merges the WireGuard and VPN sections. ↫ Marcus Nestor at 9To5Linux While Cinnamon is first and foremost a Linux Mint project, it's available on countless other distributions as well, including dedicated variants for popular distributions like Fedora and Ubuntu. Its Wayland support is finally materialising too, which is long overdue.

This is a story of how we got from something like this: Failed to deserialize BUILDINFO file: Parser failed with the following error: unknown ^ invalid makepkg build environment option expected `buildflags`, `ccache`, `check`, `color`, `distcc`, `sign`, `makeflags` To this: When the ALPM project started, the goal was fairly simple: Better tooling to interact with the low-level plumbing of Arch Linux Package Management (ALPM). This meant binaries to read/write individual file types, better error messages, extensive specifications and of course exports to common dataformats like JSON. The thing is, although some of us already had experience with low-level dataframe parsing, …

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which. Learning about alpm-hooks(5) and alpm-install-scriptlet(5) files …
