NASA’s TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission has started collecting preliminary science data, including tandem measurements that are key to the mission’s science goals. One of the two satellites, Space Vehicle 2, completed commissioning and is fully operational. The other satellite, Space Vehicle 1, is also operating withContinue Reading
The New River Gorge bridge near Fayetteville, West Virginia, is the longest single-span steel arch bridge in the United States. Data from satellites like NASA’s NISAR will make it possible to track bridge health remotely to help ensure structural integrity of more than 60% of long span bridges worldwide. GaryContinue Reading

This artist’s concept depicts the boundary of the Sun’s atmosphere, known as the Alfvén surface. The area appears to shift between spiky and frothy, and it is the point of no return for material that escapes the Sun’s magnetic grasp. Deep dives through the Alfvén surface using NASA’s Parker SolarContinue Reading

A sudden, unexplained mass die-off is decimating sea urchins around the world, including catastrophic losses in the Canary Islands. Key reef-grazing species are reaching historic lows, and their ability to reproduce has nearly halted in some regions. Scientists suspect a pathogen but haven’t yet confirmed the culprit. The fate ofContinue Reading
