NASA announced Wednesday that it's moving forward with PRIMA (PRobe far-Infrared Mission for Astrophysics), a space telescope designed to explore the history and evolution of the universe. Because nothing says "we've got this cosmic mystery thing under control" like building yet another telescope to look at the same universe from a slightly different angle.

PRIMA is the first in a new class of NASA astrophysics missions called Probe Explorers, operating within the agency's longstanding Explorers Program. "The PRIMA mission is humanity's next window into the deep universe. It will unveil the obscure across cosmic time to better understand the formation of planets, stars, black holes, and even how water on Earth came to be," said Nicky Fox, associate administrator of NASA's Science Mission Directorate in Washington. No pressure, PRIMA.

The mission has been selected to move into Phase B, the stage where preliminary design and technology development get hashed out. Before it can proceed to Phase C, it faces a confirmation review based on technical, programmatic, and cost performance. If confirmed, PRIMA's project cost is capped at $1.2 billion - not counting launch and other non-project costs, because those are apparently the cosmic equivalent of "accessories sold separately." The observatory is targeted for launch in 2033, with a planned five-year mission.

Equipped with a 5.9-foot telescope, PRIMA will conduct deep, sensitive surveys of the universe in far-infrared light, bridging the gap between existing infrared observatories like NASA's James Webb Space Telescope and radio telescopes. By studying radiant energy that only emerges in the far-infrared, PRIMA will tackle questions about the origins of exoplanets, how galaxies and their black holes grew and evolved over cosmic history, and how dust and heavy elements accumulated over time - all contributing to a clearer picture of why the universe looks the way it does today. In short: it's the universe's backstory, now in far-infrared.

"A single mission alone can't probe all the universe's mysteries. But by extending the survey capabilities of our fleet into far-infrared wavelengths with PRIMA, we're enabling an incredibly comprehensive look at the cosmos," said Shawn Domagal-Goldman, director of NASA's Astrophysics Division. "With our Webb and Roman space telescopes, we set a cadence of launching premiere-class missions in both halves of the decade. We're going to keep that up and kick off the next decade with PRIMA, as part of a pipeline that will consistently have missions of this caliber ready to go." Because if there's one thing NASA loves, it's a launch schedule that sounds suspiciously well-organized.

The National Academies of Sciences, Engineering, and Medicine's 2020 Decadal Survey, Pathways to Discovery in Astronomy and Astrophysics for the 2020s, recommended NASA establish this new Probe Explorers mission class. NASA selected PRIMA after detailed evaluation of concept studies based on scientific merit, feasibility of development plans on cost and schedule, and use of technologies that could support future large missions. In other words: it checked enough boxes.

NASA's Jet Propulsion Laboratory in Southern California will manage the PRIMA mission. Other partners include NASA's Goddard Space Flight Center in Greenbelt, Maryland, and NASA's Marshall Space Flight Center in Huntsville, Alabama. International partners contributing to the mission include CNES (Centre National D'Etudes Spatiales), ASI (Agenzia Spaziale Italiana), DLR (Deutsches Zentrum für Luft- und Raumfahrt), CSA (Canadian Space Agency), KASI (Korea Astronomy and Space Science Institute), JAXA (Japan Aerospace Exploration Agency), and the UK Space Agency. Because exploring the universe is expensive, and splitting the bill is apparently a universal constant.

The Explorers Program is NASA's oldest continuous program, designed to provide frequent, low-cost access to space using principal investigator-led space science investigations relevant to the Science Mission Directorate's astrophysics and heliophysics programs. Since the Explorer 1 launch in 1958 - which discovered Earth's radiation belts - the program has launched more than 100 missions, including the Uhuru and Cosmic Background Explorer missions that led to Nobel prizes for their investigators. So yes, PRIMA is following in some rather large, Nobel-winning footsteps.

The Explorers Program is managed by NASA Goddard for the Science Mission Directorate, which conducts research and scientific exploration programs for Earth studies, space weather, the solar system, and the universe.
