How confident are we about the safety of commercial space tourism? Long-time Slashdot reader theodp writes: It's one thing for Microsoft to boast that they dare to use Outlook instead of Gmail. But it took a whole other level of commitment for Jeff Bezos to join his brother Mark aboard Blue Origin's first passenger-carrying mission in July 2021. So, while Bezos is unhesitant about sending himself and other celebrities and loved ones into space aboard Blue Origin, how confident are you about the current state of space travel safety? If offered a free ride into space from Bezos's Blue Origin, or one of the other options like Virgin Galactic, Axiom Space, or Boeing's Starliner, would you accept or decline it? Share your own thoughts and answers in the comments. Would you accept a free ride into space?

Can a new 3D-printing technique shorten 3D printing times to just seconds? A team of researchers in Europe has modified Tomographic Volumetric Additive Manufacturing, which can "create entire objects in one shot by shining light patterns into liquid resin," according to the 3D Printing Industry blog. (The liquid resin then solidifies when the light intensity is high enough...) While this approach can fabricate support-free, micro-scale parts within tens of seconds, it is "highly inefficient." This is because under 1% of the encoded light reaches the resin vial. Conventional TVAM can also lead to unwanted distortions and poor resolution due to light blurring and projection artifacts. To address these limitations, the researchers developed HoloVAM, a new technique that uses a 3D hologram instead of conventional volumetric light projections. This approach reportedly boosts light efficiency by 20 times, resulting in faster and more accurate 3D printing. According to their paper, published in Nature Communications, HoloVAM successfully fabricated several millimeter-scale objects in under 60 seconds with fine details as small as 31 micrometers... They believe this new approach offers value for medical bioprinting applications, thanks to HoloVAM's use of "self-healing beams." These can generate and retain their shape when passing through materials, which is particularly valuable when 3D printing with cell-laden bio-resins and hydrogels.

Petawatt lasers have already allowed scientists to "manipulate materials in new ways, emulate the conditions inside planets, and even split atoms," reports Science magazine. "Now, accelerator physicists have matched that feat, producing petawatt pulses of electrons that could also have spectacular applications..." Described in a paper published Thursday in Physical Review Letters, the electron pulses last one-quadrillionth of a second but carry 100 kiloamps of current. "It's a supercool experiment," says Sergei Nagaitsev, an accelerator physicist at Brookhaven National Laboratory who was not involved in the work. Richard D'Arcy, a plasma accelerator physicist at the University of Oxford, adds, "It's not just an experimental demonstration of something interesting, it's a steppingstone on the way to megaamp beams." If achievable, those even more powerful beams might begin to perform extraordinary feats such as ripping particles out of empty space, he says... [A]mped-up lasers would open the way to, for example, probing chemical processes as they happen, says Sergei Nagaitsev [an accelerator physicist at Brookhaven National Laboratory who was not involved in the experiment]. "These are the easy pickings." An ultraintense electron pulse could also be used to generate plasmas like those seen in astrophysics, such as the jets of matter and radiation that shoot out of certain stellar explosions at near-light-speed. Researchers need only fire the electron beam into the right target. "This is a fantastic relativistic drill," Ferrario says. "The interaction of this with matter could be very interesting." Superintense electron bunches might someday even probe the nature of empty space. They produce a hugely intense electric field, so if one of them were to collide with an ultraintense laser pulse, which also contains a huge electric field, it would expose space to an incredibly strong electrical polarization, D'Arcy notes. If that field is strong enough, it should begin to rip particle-antiparticle pairs out of the vacuum, a phenomenon predicted by quantum physics but never observed. "You can access areas of particle physics that are inaccessible elsewhere," Darcy says. Thanks to Slashdot reader sciencehabit for sharing the article.

A malicious PyPi package effectively turned its users' systems "into an illicit network for facilitating bulk music downloads," writes The Hacker News. Though the package has been removed from PyPI, researchers at security platform Socket.dev say it enabled "coordinated, unauthorized music downloads from Deezer — a popular streaming service founded in France in 2007." Although automslc, which has been downloaded over 100,000 times, purports to offer music automation and metadata retrieval, it covertly bypasses Deezer's access restrictions... The package is designed to log into Deezer, harvest track metadata, request full-length streaming URLs, and download complete audio files in clear violation of Deezer's API terms... [I]t orchestrates a distributed piracy operation by leveraging both user-supplied and hardcoded Deezer credentials to create sessions with Deezer's API. This approach enables full access to track metadata and the decryption tokens required to generate full-length track URLs. Additionally, the package routinely communicates with a remote server... to update download statuses and submit metadata, thereby centralizing control and allowing the threat actor to monitor and coordinate the distributed downloading operation. In doing so, automslc exposes critical track details — including Deezer IDs, International Standard Recording Codes, track titles, and internal tokens like MD5_ORIGIN (a hash used in generating decryption URLs) — which, when collected en masse, can be used to reassemble full track URLs and facilitate unauthorized downloads... Even if a user pays for access to the service, the content is licensed, not owned. The automslc package circumvents licensing restrictions by enabling downloads and potential redistribution, which is outside the bounds of fair use... "The malicious package was initially published in 2019, and its popularity (over 100,000 downloads) indicates wide distribution..."

Watch the "Blue Ghost" lunar lander attempt its moon landing. The actual landing is scheduled to happen at 3:34 a.m. Eastern time, according to CNN, while "The first images from the mission should be delivered about a half hour after..." Success is not guaranteed... [B]roadly speaking, about half of all lunar landing attempts have ended in failure. Jason Kim, Firefly's CEO, told CNN in December that his company's experience building rockets has given him a high degree of confidence in Blue Ghost's propulsion systems. "We're using (reaction control system) thrusters that we've built, developed in-house, that are designed by the same people that design our rocket engines. That reduces risk," Kim said. "All that gives us high confidence when we have people that do rocket engines really, really well — some of the best in the world." But the New York Times notes that Blue Ghost, built by Austin, Texas-based Firefly Aerospace, is just one of three robotic spacecraft "in space right now that are aiming to set down on the moon's surface." Blue Ghost has performed nearly perfectly. For the first 25 days, it circled Earth as the company turned on and checked the spacecraft's systems. It then fired its engine on a four-day journey toward the moon, entering orbit on February 13. The spacecraft's cameras have recorded close-up views of the moon's cratered surface... On the same SpaceX Falcon 9 rocket that launched Blue Ghost to orbit was Resilience, a lunar lander built by Ispace of Japan. The two missions are separate, but Ispace, seeking a cheaper ride to space, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload... Although Resilience launched at the same time as Blue Ghost, it is taking a longer, more fuel-efficient route to the moon and is expected to enter orbit around the moon in early May. The third lunar lander heading to the moon is Athena (from Intuitive Machines), which launched Thursday on a SpaceX Falcon 9 rocket, "marking the first time humanity has had three lunar landers en route to the Moon at the same time," according to a statement from the company. Space.com notes that "To date, just one private spacecraft has ever landed successfully on the moon — Intuitive Machines' Odysseus, which did so in February 2024." Athena launched with several other spacecraft last night, including Odin, a scouting probe built by the asteroid-mining company Astroforge, and NASA's water-hunting Lunar Trailblazer. Lunar Trailblazer is also moon-bound, though it's headed for orbit rather than the surface...

Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone) shared an interesting blog post. They'd spotted a Reddit post "detailing how someone took a 27-year-old visual basic EXE file, fed it to Claude 3.7, and watched as it reverse-engineered the program and rewrote it in Python." It was an old Visual Basic 4 program they had written in 1997. Running a VB4 exe in 2024 can be a real yak-shaving compatibility nightmare, chasing down outdated DLLs and messy workarounds. So! OP decided to upload the exe to Claude 3.7 with this request: "Can you tell me how to get this file running? It'd be nice to convert it to Python."> Claude 3.7 analyzed the binary, extracted the VB 'tokens' (VB is not a fully-machine-code-compiled language which makes this task a lot easier than something from C/C++), identified UI elements, and even extracted sound files. Then, it generated a complete Python equivalent using Pygame. According to the author, the code worked on the first try and the entire process took less than five minutes... Torrone speculates on what this might mean. "Old business applications and games could be modernized without needing the original source code... Tools like Claude might make decompilation and software archaeology a lot easier: proprietary binaries from dead platforms could get a new life in open-source too." And maybe Archive.org could even add an LLM "to do this on the fly!"
