Over the past decade, global space launch cadences have grown dramatically, frequently placing multiple payloads into orbit on a single booster. Robust Space Domain Awareness (SDA) and precise characterization of resident space objects are vital to safeguarding the orbital environment. To confront this emerging national security risk, a team of scientists at Lawrence…
A team of Lawrence Livermore National Laboratory (LLNL) scientists and engineers pushed the limits of unmanned aerial systems to earn a place at the DARPA Lift Challenge, hosted by the Defense Advanced Research Projects Agency (DARPA). The LLNL Collaborative Heavy-lift Aerial unManned Propellor Systems (CHAMPS) team ranked among the 132 teams selected from more than 480…
“The history of failure in war can almost be summed up in two words: too late.” General Douglas MacArthur’s warning underscored the urgency and importance of the first Decision Superiority Summit, hosted this summer by Lawrence Livermore National Laboratory (LLNL), where Department of War (DOW) decision makers, scientists, engineers and analysts explored how computer…
At the bottom of the ocean, optical fibers transmit telecommunications and internet data across the world. Waveguides make that feat possible by channeling and amplifying the light — and therefore the data within — over enormous distances. And the technology goes beyond undersea cables. Waveguiding optics are among the most important advances in photonics since the…
Lawrence Livermore National Laboratory (LLNL) scientists and engineers have been selected to lead 10 Phase I projects under the U.S. Department of Energy’s (DOE’s) Genesis Mission, applying AI to challenges spanning high-performance computing (HPC), fusion energy, Earth systems science, materials discovery, biology, quantum technologies and fundamental physics. LLNL…
Lawrence Livermore National Laboratory (LLNL) has completed delivery of the first 220 line-replaceable units (LRUs) to the Integrated Test Stand (ITS) at Nevada National Security Sites (NNSS), as well as the first 100 LRUs to be used at NNSS’s underground facility, the Principal Underground Laboratory for Subcritical Experimentation (PULSE). The two major hardware delivery…
For decades, manufacturing plastic-bonded high explosives, or PBXs, has relied on legacy processes like slurry coating. In this method, explosive crystals are mixed with a binder, a polymer that helps hold the material together, to form small granules called prills. Those prills are then pressed into dense explosive parts. This process is difficult to control, inefficient…
Officials with the National Nuclear Security Administration (NNSA) and Lawrence Livermore National Laboratory (LLNL) celebrated the completion of the Digital Infrastructure Capability Expansion (DICE) facility on June 9, marking a major milestone in a decade-long effort to modernize one of the Lab’s most critical infrastructure systems. The 13,000-square-foot facility,…
Lawrence Livermore National Laboratory (LLNL) is contributing AI-enabled payload optimization and advanced modeling and simulation expertise to Aires Tide, a collaborative National Nuclear Security Administration (NNSA) demonstration exploring new ways to design flight test vehicles. Developed in collaboration with Sandia National Laboratories, Los Alamos National…
At your dentist's office, an X-ray machine fires a brief pulse of radiation, enough to find a cavity. Now imagine scaling that concept up by billions, producing a flash powerful enough to see through more than a foot of solid steel and capture a stop-motion image of an explosive experiment in progress. That's the Flash X-Ray machine, or FXR, at Lawrence Livermore National…
Nuclear materials are rarely quiet. Even when hidden inside a sealed container, they emit a kind of heartbeat through streams of particles and radiation that carry critical information about its contents. In a laboratory, scientists have the tools and expertise to read that heartbeat. But in an emergency, first responders need a way to interpret it quickly, without highly…
Lawrence Livermore National Laboratory (LLNL) marked Site 300’s 70th anniversary in May with two events celebrating the Experimental Test Site’s history, mission and people: an Employee Appreciation Day and a family-focused open house. Although Site 300 reached its 70-year milestone last fall, celebrations were delayed due to a lapse in federal government funding. The…
Imagine listening to an orchestra: overlapping notes, blended timbres and complex harmonies coming together into a cohesive symphony. Now try to isolate a single instrument and the sounds it produces. Nearly impossible, right? The same is true for collections of ions, charged particles that have gained or lost electrons. Each ion — from hydrogen to lithium to lead and…
When hydrogen gas interacts with uranium metal, the combination creates a chemically reactive powder and a runaway reaction that is difficult to stop. The result can impact the safety and lifespan of technology critical for fusion energy, hydrogen storage and nuclear fuels. In a recent study published in npj Materials Degradation, researchers from Lawrence Livermore…
In less than a millionth of a second after a nuclear detonation or a severe nuclear reactor accident, an enormous burst of energy heats the surrounding air and materials. Everything in the vicinity is vaporized into a hot, glowing cloud of gas and plasma. As that nuclear fireball expands, it mixes with air, begins to cool and condenses into tiny solid particles — creating…
LLNL tackles the nation’s toughest security challenges through bold, multidisciplinary science powered by advanced facilities and instruments. In this new series, meet the machines that work behind the scenes at the Laboratory to drive discovery, push boundaries and enable excellence. From inspecting optics and trapping ions to cooling supercomputers and detecting…
Scientific discovery has always moved through a familiar cycle: question, hypothesis, experiment and a result. In the latest episode of the Big Ideas Lab podcast, Lawrence Livermore National Laboratory (LLNL) explores how the Department of Energy’s (DOE) Genesis Mission aims to accelerate that process by uniting AI, high-performance computing (HPC), experiments and the…
Lawrence Livermore National Laboratory (LLNL) leaders, scientists and engineers joined national voices at the Special Competitive Studies Project’s (SCSP) AI+ Expo May 7-9 in Washington, D.C., highlighting how AI is reshaping science, security and energy innovation. The public Expo brought together government, industry, academic and Department of Energy (DOE) national…
A team of scientists at Lawrence Livermore National Laboratory (LLNL) recently delivered a high-resolution optics system to Firefly Aerospace in support of Firefly’s Ocula commercial lunar imaging service. The payload is scheduled to fly onboard Firefly’s Elytra spacecraft in lunar orbit as part of Blue Ghost Mission 2, targeted to launch no earlier than late 2026. The…
Sonny Ly has built a career at Lawrence Livermore National Laboratory (LLNL) combining laser physics, materials science and mentorship.
