NASA has selected the PRobe far-Infrared Mission for Astrophysics, known as PRIMA, to advance to Phase B development as the agency’s first Probe Explorer mission, with a targeted launch in 2033 and a budget capped at $1.2 billion, universetoday.com reported. Operating within the Explorers Program, the observatory will fill a critical technological gap between near-infrared space telescopes like the James Webb Space Telescope and radio telescopes, according to mashable.com.
Building a $1.2 Billion Far-Infrared Telescope for 2033
NASA capped PRIMA’s budget at $1.2 billion, excluding the rocket launch and other non-project costs, as reported by universetoday.com and today.uconn.edu. The project completed a preliminary phase with $5 million in funding before advancing to Phase B, where engineers will refine the observatory design and test its technology, according to mashable.com and today.uconn.edu. The spacecraft features a 1.8-meter, or 5.9-foot, mirror and sensors that will chill down to hundreds of degrees below freezing to detect faint cosmic signals, mashable.com reported.
PRIMA represents a lower-cost middle ground in NASA’s mission pipeline, bridging small science missions and giant flagship observatories, mashable.com noted. Nicky Fox, associate administrator for NASA’s Science Mission Directorate, called the observatory humanity’s next window into the deep universe in a statement cited by universetoday.com and newsbytesapp.com. Shawn Domagal-Goldman, director of NASA’s Astrophysics Division, stated that extending survey capabilities into far-infrared wavelengths enables a comprehensive look at the cosmos, according to newsbytesapp.com.
PRIMA Telescope Peers Through Cosmic Dust to See Newborn Stars
PRIMA will target far-infrared light, a band of the spectrum that is largely absorbed by water vapor in Earth’s atmosphere, mashable.com reported. Because cold gas and dust glow in far-infrared wavelengths, the telescope will allow astronomers to peer through cosmic dust that blocks visible light and hides newborn stars, growing black holes, and planet-building material, according to mashable.com and imperial.ac.uk.
Jason Glenn, who led the PRIMA concept study, stated that the observatory will dramatically change our understanding of fundamental contemporary astrophysics, as reported by today.uconn.edu. Dave Clements, associate professor of astrophysics at Imperial College London, added that about half of the energy generation in the universe is hidden by dust, and far-infrared telescopes can see through that dust to the processes inside, according to imperial.ac.uk.
Advancing International Collaboration and Student Training for Phase B
The international collaboration behind PRIMA includes researchers from the United States, Europe, and Asia, with UK contributions supported by the UK Space Agency involving teams from the University of Sussex, Imperial College London, Cardiff University, STFC’s RAL Space, and Celtic Terahertz Technologies, imperial.ac.uk reported.
As the mission progresses through Phase B preliminary design, NASA and its partners face confirmation reviews to assess capabilities, cost-effectiveness, and readiness before advancing to Phase C, universetoday.com reported. While the 2033 launch target is set for a planned five-year mission, researchers at institutions like Imperial College London are actively building data reduction tools and analytical instruments, leaving open the question of how quickly the science team can process the unprecedented data volumes PRIMA is expected to collect.
