NASA's Jet Propulsion Laboratory released an artist's concept depicting the proposed design for the PRobe far-Infrared Mission for Astrophysics, or PRIMA. According to the image description, NASA selected the mission in September 2026.

PRIMA is described as the first in a new class of NASA astrophysics missions called Probe Explorers, which sit within the agency's long-standing Explorers Program. By observing far-infrared light, the observatory would let scientists study cosmic objects heavily obscured by dust, offering new insight into the formation of planets, stars and black holes, and even how water on Earth came to be.

The concept remains subject to agency confirmation. If confirmed, PRIMA would be targeted to launch in 2033 for a planned five-year mission. The image carries the identifier PIA26355 and is credited to NASA/JPL-Caltech.
