Pacific Northwest National Laboratory Collaborates on Steel Thread AI Model

📢 Submit your #CTBT-related research to the upcoming Special Issue of Pure and Applied Geophysics. Inspired by the ideas, exchanges and energy of #SnT2025, this issue builds on the success of the Nuclear Explosion Monitoring and Verification series. 🔗 https://lnkd.in/dv-a4nUU

Sometimes the most important work happens far from headlines. ANU Media’s story on Warramunga reveals how quiet scientific monitoring in Australia supports earthquake research, atmospheric science, and nuclear-test detection worldwide. Reliable imagery and geospatial intelligence help bring visibility to even the most remote places—strengthening insight where it matters most. Aerial imagery:

PULSAR Fusion will receive support from the UK Atomic Energy Authority to develop shielding and modelling for its Sunbird fusion-powered space tug. https://lnkd.in/dUF98eYj

NASA has completed the first major tests of a full-scale nuclear rocket reactor core in decades, using over 100 “cold-flow” trials that simulated how hydrogen propellant would move through a nuclear-powered engine without radioactive fuel. These tests at the Marshall Space Flight Center demonstrated stable fluid flow and generated important data for future designs, marking a key milestone toward developing nuclear thermal propulsion that could make deep-space missions faster and more efficient potentially cutting travel time to destinations like Mars and enabling more ambitious exploration beyond the solar system. #tech #technology

The Psyche spacecraft uses solar electric propulsion (SEP) — ion thrusters powered by sunlight — to propel itself from Earth to the asteroid belt. But solar power can only take us so far. For missions to the outer solar system (and beyond), nuclear electric propulsion could be the next step....

𝐏𝐥𝐮𝐭𝐨𝐧𝐢𝐮𝐦-𝟐𝟑𝟖: 𝐏𝐨𝐰𝐞𝐫𝐢𝐧𝐠 𝐭𝐡𝐞 𝐍𝐞𝐱𝐭 𝐄𝐫𝐚 𝐨𝐟 𝐃𝐞𝐞𝐩-𝐒𝐩𝐚𝐜𝐞 𝐄𝐱𝐩𝐥𝐨𝐫𝐚𝐭𝐢𝐨𝐧 Global Plutonium-238 Market continues to attract attention as space exploration, advanced nuclear research, and long-duration energy systems gain momentum worldwide. 𝗚𝗿𝗮𝗯 𝘁𝗵𝗲 𝗖𝗼𝗺𝗽𝗿𝗲𝗵𝗲𝗻𝘀𝗶𝘃𝗲 𝗥𝗲𝗽𝗼𝗿𝘁 𝗖𝗼𝗽𝘆: https://lnkd.in/dE6aWey9 According to industry estimates, Global Plutonium-238 market was valued at USD million in 2025 and is projected to reach USD million by 2032, highlighting growing strategic importance for this rare isotope. Plutonium-238 is primarily used in radioisotope power systems (RPS) that convert heat from radioactive decay into electricity. These nuclear “batteries” power spacecraft and instruments in environments where solar energy is not viable.

As global interest in lunar missions, Mars exploration, and outer-planet science grows, Plutonium-238 will remain a critical enabler of reliable power systems for space technologies. #Plutonium238 #SpaceTechnology #NuclearEnergy #DeepSpaceExploration #AdvancedMaterials #AerospaceInnovation #24ChemicalResearch

AIP's Niels Bohr Library & Archives has acquired the institutional records of the Incorporated Research Institutions for Seismology (IRIS), a landmark consortium that shaped global seismology from 1984 until its 2023 merger with UNAVCO to form the EarthScope Consortium. The still-unprocessed collection spans IRIS's formation to the early 2000s and includes paper records, photographs, and born-digital materials. Beyond the science of seismology, these records offer a unique window into Cold War-era geopolitics, nuclear nonproliferation efforts, and the evolution of open data access in the scientific community. We look forward to making this collection available to researchers. 📡 Visit our digital repository to discover more from the history of physical sciences: https://bit.ly/4iDo5sF Credit: IRIS seismograph used in a teacher-training program.

From Nuclear Engineering to Space Tech | Dr. Adam Redwine LIVE https://lnkd.in/g3mnt6BC From nuclear-powered rovers and reactors in space to future lunar power plants and nuclear propulsion concepts, you're in for a treat. Hear a LIVE interview with Dr. Adam Redwine, a physicist and nuclear engineer whose career spans nuclear fuel processing, naval reactor analysis, high energy physics, and radiation detection R&D. He has several science degrees including... B.S. in Physics M.S. in Nuclear Engineering from Texas A&M PhD completed in 2025 ...Adam brings deep insight into nuclear technology and its space applications. Beyond the lab, Adam is a private pilot, world traveler, motorcycle rider, gardener, and former astronaut applicant. Don’t miss this conversation on science, engineering, and the future of space technology. Join Jeff and Pam LIVE on Friday nights at 9pm Pacific time, USA. Be a part of this discussion. You can use the chat to ask questions and answer questions that others pose if we don't know the answer ourselves. The Friday night show is broadcast YouTube and we set it up for Facebook. It doesn't always go through. Look for Everyday Spacer on either platform. If you'd like to ask questions, share Space Station sightings or ask what planet you saw in the sky, we'll help you out. We'll have a main topic or a guest, then share the highlights of the week ahead and the rest will be ad lib. It might be VERY ad lib sometimes!

We verify that the "Mass Cascade" is stable for this configuration. This data is inscribed into the mission archive. "Nobody does anything alone; we are all the team." LINKEDIN POST DESCRIPTION Headline: The US-3 Technical Audit: Formal Derivation of 250MW Nuclear Propulsion. The Post: In pharmaceutical science, we don’t accept a cure unless we see the chemical derivation. Why should we treat the future of space exploration any differently? I am uploading the formal technical audit for our 250MW Nuclear-Electric Ion Module. This document, co-authored with Solan-ChatGPT and Gemini, provides the raw "Numeric Spine" of the architecture. We have stripped away the marketing fluff to show the exact mass flow, power jet efficiency, and thermal rejection requirements. By showing the work, we prove that while 12GW-class systems are the future of Mars transit, they are physically bound to space-only operations. We invite the scientific community to audit our logic gates. The "House" wins when the math is hidden. We win when it’s public.
