Hurricane Simulator

Wind engineers at the University of Florida (UF) have developed the world's largest portable hurricane wind and rain simulator. UF engineers plan to use the machine to blast vacant homes with Category 3 hurricane winds of up to 130 mph, and high-pressure water jets that mimic wind-driven torrential rain. The goal is to learn...

Medical imaging technology has led to quicker diagnoses of conditions that, when caught early, can be treated. Because such devices are large, however, they are impractical in the limited area of a space vehicle. An on-going NASA project to address the issue involves image fusion, where in-orbit ultrasounds would be combined...
