Description These images were part of the first successful use of a new technology called Mars Global Localization, developed at NASA’s Jet Propulsion Laboratory. Using its navigation cameras, NASA’s Perseverance captured a 360-degree view of the surrounding terrain that was matched…

Description Using its navigation cameras, NASA’s Perseverance Mars rover captured the five stereo pairs of images that make up this panorama on Feb. 2, 2026, the 1,762nd day, or sol, of the mission. A new technology called Mars Global Localization…

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…

NASA continues to press ahead through the Artemis II wet dress rehearsal countdown – a fueling test of the SLS (Space Launch System) rocket. Early this morning, at approximately 3 a.m. EST, teams powered up the rocket’s core stage, which…

Listen to this audio excerpt from Katie Oriti, Orion European Service Module Integration Office manager: Growing up in rural America, Katie Oriti could only dream of working for NASA. Not because she wasn’t inspired by the dark, star-filled skies of…

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…
