Webb Uncovers Unexpected Phenomena Above Jupiter’s Great Red Spot

Using the James Webb Space Telescope, scientists observed the region above Jupiter ’s iconic Great Red Spot to discover a range of previously unseen features. The region, previously believed to be unremarkable in nature, hosts a variety of intricate structures and activity.

Recent observations by Webb’s NIRSpec revealed surprising details about Jupiter’s upper atmosphere, particularly above the Great Red Spot, showing complex structures influenced by gravity waves. These findings, captured using Webb’s high-resolution capabilities, could support the Jupiter Icy Moons Explorer (Juice) mission, enhancing our understanding of Jupiter and its moons.

Research team creates process to grow sub-nanometer transistors

Why it matters: Moore’s Law might not be dead after all. A new technique using nanomaterials can further miniaturize transistors, allowing fab plants to pack more of them on each chip. This research opens up new possibilities for creating advanced semiconductor devices with features smaller than current lithography techniques allow.

A South Korean research team led by Director Jo Moon-Ho of the Center for Van der Waals Quantum Solids within South Korea’s Institute for Basic Science has made a significant advancement in semiconductor and nanomaterial technology that could lead to the development of much smaller, more efficient, and more powerful electronic devices. The new technique can grow “one-dimentional” metallic nanaomaterials with widths as narrow as 0.4 nanometers for use as gate electrodes on 2D substrates. The technique promises to overcome the limitations of traditional lithography.

Integrated devices based on two-dimensional semiconductors exhibit excellent electrical properties even when thinned to atomic-scale thickness, making them promising candidates for creating ultra-thin, high-performance electronic devices. A separate study indicates that these 2D logic circuits are promising candidates for the post-Moore’s Law era.

Even short trips to space can change an astronaut’s biology − a new set of studies offers the most comprehensive look at spaceflight health since NASA’s Twins Study

Editor’s note: Video above is about a NASA astronaut discussing an extended stay in space.

(THE CONVERSATION) – Only about 600 people have ever traveled to space. The vast majority of astronauts over the past six decades have been middle-aged men on short-duration missions of fewer than 20 days.

Today, with private, commercial and multinational spaceflight providers and flyers entering the market, we are witnessing a new era of human spaceflight. Missions have ranged from minutes, hours and days to months.

NASA seeks industry support in GLIMR concept study

WASHINGTON — The National Aeronautics and Space Administration (NASA) has announced that the agency is seeking assistance from industry as it begins a study into its Geostationary Littoral Imaging and Monitoring Radiometer (GLIMR) Access to Space (ATS) approach.

The GLIMR mission aims to provide transformative rapid observations of dynamic coastal zone ecosystems throughout the Gulf of Mexico (GoM) and coastal continental U.S. (CONUS). Its goal is to observe and monitor ocean biology, chemistry, and ecology to help protect ecosystem sustainability, improve resource management, and enhance economic activity. This includes identifying and tracking harmful algal blooms and oil spills, while also observing, quantifying, and understanding processes associated with rapid changes in phytoplankton growth.

The GLIMR ATS scope is expected to include several key components and activities: the spacecraft itself, the launch vehicle, the integration and testing of the GLIMR payload with the spacecraft, and the integration of the spacecraft with the launch vehicle and subsequent launch. It will also cover the command uplink from the industry-provided Mission Operations Center (MOC), the downlink of GLIMR engineering and science telemetry to industry-allocated ground stations, and the delivery of error-checked GLIMR data to various mission partners. Additionally, it encompasses all related tasks and support required during the planned GLIMR Mission, such as pre-launch planning, launch support, in-orbit check-out, and operations.

Army asks industry for navigation warfare waveforms in counter-PNT technology to disrupt enemy operations

ABERDEEN PROVING GROUND, Md. – U.S. Army electronic warfare (EW) experts are reaching out to industry for new ways to design electronic payloads that counter enemy positioning, navigation, and timing (PNT).

Officials of the Army Contracting Command at Aberdeen Proving Ground, Md., issued a request for information (W56KGURTI-24-R-1001) on Friday for the Counter-PNT Navigation Warfare Defeat project.

Counter-PNT seeks to defeat enemy satellite navigation and timing systems, such as the U.S. Global Positioning System (GPS), which are essential for navigation, communications, weapons guidance, surveillance, transportation, and financial transactions.
