SoftwareResearch teams at NASA’s Glenn Research Center are involved in developing theory and software to predict the noise from aircraft engines. This software helps engineers to design and analyze new and improved aircraft propulsion systems. Copies of our software can be requested from NASA’s Software Catalog. JeNo Development of jet noise prediction codes is multifaceted. […]
Experimental FacilitiesResearch teams at the NASA Glenn Research Center perform experiments in world-class facilities such as the 9- by 15-Foot Low-Speed Wind Tunnel (9 x15 LSWT), the Aero-Acoustic Propulsion Laboratory (AAPL), the Small Hot Jet Acoustic Rig (SHJAR), the Nozzle Acoustic Test Rig (NATR), the DGEN AeroPropulsion Research Turbofan (DART), and the Acoustical Testing Laboratory (ATL).

NASA’s Simulated Mars Crew Marks One Year Inside Habitat The four crew members in NASA’s simulated Mars mission have spent the past year living and working in isolation in a confined habitat at NASA’s Johnson Space Center in Houston.
InstrumentationTo 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 DawnNASA’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 […]
