There is no GPS at the Red Planet, but a new technology called Mars Global Localization lets Perseverance determine precisely where it is — without human help. Imagine you’re all alone, driving along in a rocky, unforgiving desert with no roads, no map, no GPS, and no more than one phone call a day for […]

Not because she wasn’t inspired by the dark, star-filled skies of her hometown Shelby, Ohio, but because it felt out of reach. “I think NASA was […]
NASA’s Hubble Identifies One of Darkest Known Galaxies
In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible — low-surface-brightness galaxies dominated by dark matter and containing only a sparse scattering of faint stars. One such elusive object, dubbed CDG-2, may be among the most heavily dark matter-dominated […]
TB 26-02 Effects of Large Grain Size in Composite Overwrapped Pressure Vessel
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 a series of custom-designed coupons that […]
