The Human Fingerprint on Earth’s Water Cycle
Tue, 20 Oct 2026 04:01:00 +0000
Human activities have become intertwined with how water is distributed across the continents. A new study brings their effects into sharper focus.
Curiosity Blog, Sols 5036-5042: Watching the Clouds Go By
Tue, 20 Oct 2026 01:21:38 +0000
Written by Alex Innanen, Atmospheric Scientist at York University Earth planning date: Friday, Oct. 9, 2026 Happy New Mars Year! We mark the start of a new year on Mars at the beginning of the northern hemisphere spring, or the vernal equinox. We then keep track of the seasons by counting degrees of solar longitude […]
NASA Improves Shock, Vibration Analysis
Mon, 19 Oct 2026 19:28:32 +0000
Rockets vibrate, shake, and flex intensely as they climb into space, and spacecraft packed with delicate scientific instruments must survive those forces. Before any rocket leaves the ground, NASA engineers work to predict how those stresses will affect every part of a spacecraft. To do that, engineers in the Dynamic Environments Group with NASA’s Launch […]
Software

Research 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. […]

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
Mon, 19 Oct 2026 16:03:51 +0000
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 […]
