NASA’s PRIMA Spacecraft (Artist’s Concept)

NASA has chosen its PRobe far-Infrared Mission for Astrophysics (PRIMA) spacecraft design, announced in September 2026. This innovative mission represents the inaugural project within NASA's newly established Probe Explorer category. PRIMA is part of the agency’s long-standing Explorers Program and focuses on utilizing observations of far-infrared light. Scientists anticipate this technology will significantly advance their understanding of celestial objects. The observatory’s primary goal involves studying cosmic phenomena through this specific wavelength range.
