Instrumentation
To measure airflow and sound, research teams at the NASA Glenn Research Center use special instrumentation like particle image velocimetry, hot wire anemometry, Raman spectroscopy, microphones in phased arrays or continuously rotating rakes. The global aviation noise reduction community relies on data from NASA GRC experiments to validate theory and noise prediction software. Rotating Rake […]

Martian Dawn
NASA’s Curiosity captures the dawn on Mars – as well as elongated ridges formed by wind erosion, or yardangs – in this close-up from a panorama released on Oct. 6, 2026. This is the most detailed view yet of distant, wind-carved Martian cliffs, highlighting features the mission’s scientists have long been waiting to see up […]
