The NASA Engineering and Safety Center (NESC) performed an assessment to characterize the effects of abnormal grain growth (AGG) within a metallic liner of a composite overwrapped pressure vessel (COPV). This effort focused on evaluating the mechanical response of the liner material, including the strain amplification factor (SAF), using aContinue Reading
Life on Earth may have learned to breathe oxygen long before oxygen filled the skies. MIT researchers traced a key oxygen-processing enzyme back hundreds of millions of years before the Great Oxidation Event. Early microbes living near oxygen-producing cyanobacteria may have quickly used up the gas as it formed, slowingContinue Reading
