Seeing the Unseeable: The Materials That Make Shockwaves Visible
In the blink of an eye, a high-velocity impact occurs. A bullet strikes armor, a micrometeoroid pummels a spacecraft, a football player suffers a helmet-to-helmet collision, or a hypersonic vehicle slices through the atmosphere at Mach 7. These events unfold in milliseconds, yet the hidden force radiating through the material—the shockwave—holds the key to…

Revolutionizing Satellite Operations: DARPA’s Robotic Servicing of Geosynchronous Satellites (RSGS) Program
The Fragile Backbone of Modern Warfare High above Earth, at 36,000 kilometers, geosynchronous orbit (GEO) holds a constellation of over 1,300 satellites valued at more than $300 billion. These satellites are the invisible backbone of modern warfare, supporting everything from missile defense to global communications and real-time intelligence. With the increasing sophistication of anti-satellite (ASAT)…
