Content overview: “NASA Selects PRIMA Far-Infrared Probe Explorer Mission for 2026 Launch”. NASA has chosen the PRobe far-Infrared Mission for Astrophysics (PRIMA) as its first Probe Explorer mission, a new class within the agency's long-running Explorers Program. The selection, announced in September 2026, paves the way for a spacecraft designed to observe the universe in far-infrared light, a wavelength range largely unexplored by previous missions. PRIMA will help scientists study the formation of planets, stars, and galaxies, as well as the cosmic dust that obscures many celestial objects from view.
By peering into the cold, dusty regions of space, PRIMA aims to answer fundamental questions about how structure emerged in the universe. The mission represents a significant step for NASA's astrophysics portfolio, bridging the gap between smaller Explorer missions and larger flagship observatories. With its advanced cryogenic instruments, PRIMA is expected to deliver transformative science and open a new window on the cosmos for astronomers worldwide.
