Could We Reach Mars Faster With Nuclear Fusion-Powered Rockets? Published on April 07, 2025 at 04:27AM Nuclear fusion — which releases four times the energy of fission — could theoretically happen sooner in space than on earth, reports CNN. "And it could help spacecraft achieve speeds of up to 500,000 miles (805,000 kilometers) per hour — more than the fastest object ever built..." With funding from the UK Space Agency, British startup Pulsar Fusion has unveiled Sunbird, a space rocket concept designed to meet spacecraft in orbit, attach to them, and carry them to their destination at breakneck speed using nuclear fusion... For now, Sunbird is in the very early stages of construction and it has exceptional engineering challenges to overcome, but Pulsar says it hopes to achieve fusion in orbit for the first time in 2027. [Pulsar's founder/CEO says the first functional Sunbird would be ready four to five years later.] If the rocket ever becomes operational, it could one d...

NFL Adopts Sony's 'Virtual Measurements' for Football's First Downs Published on April 07, 2025 at 01:04AM theodp writes: America's National Football League announced that beginning with the 2025 season, Sony's Hawk-Eye virtual measurement technology will assess and identify first downs after a ball spot. Sony's Hawk-Eye virtual measurement technology, which consists of six 8K cameras for optical tracking of the position of the ball, is operated from the NFL's "Art McNally GameDay Central Officiating Center" in New York and is integrated with the League's existing replay system. It will serve as an efficient alternative to the process of having a three-person chain crew walk chains onto the field and manually measure whether 10 yards have been met after the official has spotted the ball. However, the chain crew will remain on the field in a secondary capacity. The NFL's executive VP of football operations says their move brings "...

'Landrun': Lightweight Linux Sandboxing With Landlock, No Root Required Published on April 06, 2025 at 03:04AM Over on Reddit's "selfhosted" subreddit for alternatives to popular services, long-time Slashdot reader Zoup described a pain point: - Landlock is a Linux Security Module (LSM) that lets unprivileged processes restrict themselves. - It's been in the kernel since 5.13, but the API is awkward to use directly. - It always annoyed the hell out of me to run random binaries from the internet without any real control over what they can access. So they've rolled their own solution, according to Thursday's submission to Slashdot: I just released Landrun, a Go-based CLI tool that wraps Linux Landlock (5.13+) to sandbox any process without root, containers, or seccomp. Think firejail, but minimal and kernel-native. Supports fine-grained file access (ro/rw/exec) and TCP port restrictions (6.7+). No daemons, no YAML, just flags. Example (where --rox allo...

Ian Fleming Published the James Bond Novel 'Moonraker' 70 Years Ago Today Published on April 06, 2025 at 02:04AM "The third James Bond novel was published on this day in 1955," writes long-time Slashdot reader sandbagger. Film buff Christian Petrozza shares some history: In 1979, the market was hot amid the studios to make the next big space opera. Star Wars blew up the box office in 1977 with Alien soon following and while audiences eagerly awaited the next installment of George Lucas' The Empire Strikes Back, Hollywood was buzzing with spacesuits, lasers, and ships that cruised the stars. Politically, the Cold War between the United States and Russia was still a hot topic, with the James Bond franchise fanning the flames in the media entertainment sector. Moon missions had just finished their run in the early 70s and the space race was still generationally fresh. With all this in mind, as well as the successful run of Roger Moore's fun and campy Bond, the ...

NASA Seeks Proposals for Two More Private Astronaut Space Station Visits Published on April 06, 2025 at 01:04AM This week NASA "issued a solicitation for the next two private astronaut missions to the International Space Station," reports Space News. Scheduled after May of 2026 and then mid-2027, "These will be the fifth and sixth such missions to the ISS, part of a broader low Earth orbit commercialization effort by NASA with the ultimate goal of replacing the International Space Station with one or more commercial stations." NASA's Space Station program manager calls the missions "a key part" of helping industry partners "gain the experience needed to train and manage crews, conduct research, and develop future destinations." In short, they see the missions "providing companies with hands-on opportunities to refine their capabilities and build partnerships that will shape the future of low Earth orbit." [NASA's call for prop...

Microsoft Uses AI To Find Flaws In GRUB2, U-Boot, Barebox Bootloaders Published on April 06, 2025 at 12:04AM Slashdot reader zlives shared this report from BleepingComputer: Microsoft used its AI-powered Security Copilot to discover 20 previously unknown vulnerabilities in the GRUB2, U-Boot, and Barebox open-source bootloaders. GRUB2 (GRand Unified Bootloader) is the default boot loader for most Linux distributions, including Ubuntu, while U-Boot and Barebox are commonly used in embedded and IoT devices. Microsoft discovered eleven vulnerabilities in GRUB2, including integer and buffer overflows in filesystem parsers, command flaws, and a side-channel in cryptographic comparison. Additionally, 9 buffer overflows in parsing SquashFS, EXT4, CramFS, JFFS2, and symlinks were discovered in U-Boot and Barebox, which require physical access to exploit. The newly discovered flaws impact devices relying on UEFI Secure Boot, and if the right conditions are met, attackers can bypass security pr...
