    NASA's Perseverance rover offers clues for protecting astronauts from Martian dust

    Over more than 1,645 Martian days, NASA's Perseverance rover used PIXL and SHERLOC to measure Martian dust on samples of spacesuit materials carried aboard the rover, detecting fine particles smaller than 2.5 micrometers and ultrafine particles of about 100 nanometers. The results show that static electricity determines which surfaces dust of different particle sizes adheres to; organic polymers such as Teflon readily attract fine dust, while some materials accumulate less. These data, published in the Proceedings of the National Academy of Sciences, can inform the design of spacesuits and habitats, dust-removal procedures, and crew health standards.

    Curiosity Blog, Sols 5036-5042: Watching the Clouds Go By

    NASA's Curiosity Mars rover used its right navigation camera (Navcam) on Sol 5037 to capture a pre-sunset zenith cloud movie, recording the season's first high-altitude twilight clouds over Gale Crater. Mars Year 39 began in late September, and Gale Crater has entered autumn. The team completed wrap-up work at the "Basque Lakes" drill site, the SAM team added an extra GCMS experiment, and after the weekend the rover will drive toward the "Chiu Chiu" area.

    Curiosity captures Martian dawn and wind-eroded yardang terrain

    Curiosity used Mastcam to capture the Martian dawn and elongated ridges formed by wind erosion (yardangs) on sol 4,982, August 11; the panorama was assembled from 6 individual images after transmission to Earth and released on October 6. This is the most detailed view yet of distant wind-eroded Martian cliffs, and mission scientists look forward to seeing these features up close.

    Roll-Out Solar Arrays (IROSAs) boost International Space Station power supply

    Once all eight International Space Station Roll-Out Solar Arrays (IROSAs) are in place, they will add more than 160 kilowatts of power for station research and operations. Each array is about half the size of the original arrays and can provide about 28 kilowatts of additional power; they were designed, manufactured, and tested by Redwire under a Boeing contract. Six were installed between 2021 and 2023, and the remaining two arrived aboard the cargo bay of the SpaceX Dragon spacecraft on the company's 35th commercial resupply mission. The arrays launch in a cylindrical configuration and deploy autonomously after installation, reducing launch mass and volume.

    NVIDIA releases cuPotential and partners with multiple semiconductor companies to accelerate chip design and manufacturing with CUDA-X libraries

    NVIDIA announced the launch of cuPotential, a new CUDA-X library for developers to build AI agents that simulate atomic and molecular interactions. In early access testing, it delivered a further 2-3x speedup on already GPU-optimized workflows, and Synopsys is one of the early adopters.

    The non-sci-fi story of brain-computer interfaces: A conversation with Wang Ximing of Kongshanci | Yunqi Podcast Attent!on

    Yunqi Podcast Attent!on speaks with Wang Ximing, co-founder of the brain-computer interface project Kongshanci, about its approach of using brain-computer interfaces and neuromodulation to address psychiatric and cognitive disorders: the company was founded in October 2024 and has completed angel, Pre-A, and A rounds of financing (with Yunqi continuing to invest); it currently has three products, one of which has entered clinical use at hospitals, one is a home-oriented sleep product combining EEG with electrical stimulation (internal testing completed), and another ultrasound brain-computer interface technology is in development.
