NASA announced Wednesday a mission to explore the history and evolution of the universe, PRIMA (PRobe far-Infrared Mission for Astrophysics), is advancing to the next phase of development. This space telescope is the first in a new class of NASA astrophysics missions, called Probe Explorers, within the agency’s longstanding Explorers Program. NASA selected PRIMA to move into Phase B, the stage of development that advances the preliminary design and technology development for the mission. The mission is subject to a confirmation review, based on technical, programmatic, and cost performance, to determine its readiness to begin implementation in Phase C. If confirmed, PRIMA’s project cost is capped at $1.2 billion, not including launch and other non-project costs. The observatory will be targeted to launch in 2033, for a planned five-year mission. With a 5.9-foot telescope, PRIMA will conduct deep, sensitive surveys of the universe in far-infrared light, helping bridge the gap between e...
