NASA's PRIMA mission to open new far-infrared view of cosmos
NASA has selected PRIMA, a far-infrared space telescope, to move into Phase B of development with a planned launch in 2033. The mission will fill a gap between existing infrared and radio observatories to study planet, star, and black hole formation, as well as the origin of water on Earth. Its budget is capped at $1.2 billion, excluding launch costs.
PRIMA, a 5.9-foot telescope, will operate in the far-infrared band, a spectral range currently underserved by existing observatories. It is part of NASA's long-running Explorers Program, which has supported over a hundred missions since 1958. The telescope's design aims to bridge the observational gap between the James Webb Space Telescope and ground-based radio arrays.
The mission's scientific targets include the formation of planets, stars, and black holes, as well as the cosmic accumulation of heavy elements and dust. It will also investigate the origins of exoplanets, complementing the recently launched Roman Space Telescope, which is heading to the L2 point. PRIMA's budget is capped at $1.2 billion, excluding launch costs, and it is currently in Phase B preliminary design.
The PRIMA mission could significantly expand humanity's understanding of cosmic evolution, particularly the origins of water and planetary systems. By filling a spectral gap, it may provide data that complements existing observatories, potentially leading to new discoveries about black holes and galaxy formation. This could inspire public interest in space science and influence future mission planning, though its impact depends on successful Phase C confirmation and launch. Scientists and educators may benefit from a richer dataset, while taxpayers may see returns in technological innovation.
