Lake Unter-See in Antarctica, sealed beneath thick ice, contains unusually high levels of dissolved oxygen and cone-shaped microbial reefs resembling some of Earth’s oldest fossils.
About Subsonic Vehicle Technologies and Tools Project
Project Overview NASA’s Subsonic Vehicle Technologies and Tools (SVTT) project develops technologies and tools for various types of aircraft that fly in different speed regimes, including next-generation vertical take-off and landing and fixed-wing subsonic aircraft. The research advances knowledge, technologies, and concepts that enable major steps to lowering operating costs of the next-generation single-aisle aircraft. […]
Insights into Spallation Mechanisms of Thermal Protection System Materials from Mass Spectrometry and HyMETS Testing
Download PDF: Insights into Spallation Mechanisms of Thermal Protection System Materials from Mass Spectrometry and HyMETS Testing An effort was undertaken to investigate the mechanisms responsible for internal pressure build up within thermal protection system (TPS) materials subjected to high-enthalpy environments. Understanding how gases evolve, migrate, and interact with the microstructure of a TPS is essential for […]
