U.S. Space Force Expands Golden Dome Missile-Tracking Constellation with $1.75 Billion Order

The U.S. Space Force has placed an order for 36 additional Golden Dome missile-tracking satellites at a cost of $1.75 billion. This order expands the existing constellation designed to provide early warning and tracking capabilities against ballistic missiles and other aerial threats. The Golden Dome program aims to

NASA Explores New Method for Detecting Low-Frequency Gravitational Waves

A New Window into the Gravitational Wave Spectrum NASA researchers are exploring a novel technique for detecting gravitational waves at low frequencies, potentially opening a new window into some of the most energetic phenomena in the universe. The Astrometric Signature Approach The scientific goal, led by Paul Stankus of Brookhaven

New Power System Concept Could Enable Farther Deep Space Travel

NASA's Innovative Advanced Concepts (NIAC) program has selected a study by researcher Keunhan Park from the University of Utah to develop a next-generation power system for interstellar missions. The proposed plasmon-enhanced radioisotope thermophotovoltaic (PRTPV) generator aims to address a critical challenge in deep space exploration: generating reliable, high-efficiency

Astronomers Potentially Discover First Binary Star System With Twin Supernovae

Astronomers have potentially identified a binary star system where both stars experienced supernova explosions—an unprecedented find that could deepen our understanding of stellar life cycles. The discovery, if confirmed, would represent the first known case of a twin-star system in which both members separately exploded as supernovae. Such an

NASA Develops Compact Multi-View Particle Detector for CubeSats

A team of NASA-sponsored scientists and engineers has developed a novel compact instrument designed to observe high-energy particles in the near-Earth space environment. The instrument, built for NASA's Relativistic Electron Atmospheric Loss (REAL) CubeSat mission, incorporates miniaturized sensors into a multi-view particle detection system that differs from previous

SpaceX Launches Satellite-Servicing Mission with Robotic Arms

SpaceX has launched a new satellite-servicing mission that could mark a significant step forward for in-orbit maintenance technology. The mission, launched on July 21, carries a spacecraft developed by Northrop Grumman equipped with robotic arms capable of performing repairs and maintenance on satellites already in Earth orbit. This type of

A Hidden "Switch-Off" Signal Could Predict Solar Storms Seven Years Early

A team of researchers has uncovered a previously unknown milestone in the Sun's activity cycle that may revolutionize space weather forecasting. The discovery centers on a "switch-off" point—a specific moment when the most extreme solar phenomena abruptly cease, signaling the end of a cycle'
