NASA Science 2026 artwork commemorating America's 250th Anniversary. The illustration uses blue tones with warm pastel accents showing humanity's space exploration journey. An open history book at the bottom emits light, with Earth emerging above it. A pathway extends from the book past the Moon, Mars, and Saturn into deep space, featuring spacecraft including NISAR, ISS, Parker Solar Probe, LRO, MRO, Dragonfly, NEO Surveyor, Webb, and Roman Space Telescope.
