Posted in arXiv, a non-peer reviewed paper, by choice. These preprint servers are also handy for distribution of whitepapers, position papers, and reference works:

Moullet, A. Burgarella, D. Kataria, T. et al. PRIMA General Observer Science Book Volume 2
PRIMA is a concept for a far-infrared to submillimeter space telescope. It was conceived in the aftermath of SPICA, supposed successor to Herschel. But SPICA, from the Japanese space agency, collapsed, even after splitting the work with ESA. Now we pin our hopes on PRIMA. This “book” gives use cases and templates for anticipated PRIMA observations.
Some of the relevant observations:
EXOPLANETS, ASTROBIOLOGY, AND THE SOLAR SYSTEM
54. Measuring the Size Distribution of Inner and Outer Oort Cloud
55. Time-Critical Observations of Interstellar Objects and Impactors with PRIMAger
56. Exploratory Study of Bodies Within the Main Asteroid Belt
57. Size Distribution in the Solar System Kuiper Belt
58. Tracing Ice and Dust Across the Solar System: A Window in Evolution of Volatiles Throughout the Universe
By observing in the far-infrared, PRIMA would see things like thermal emissions, difficult or impossible from the ground. Meanwhile, PRIMA’s band is different from, e. g., Spitzer or NEO Surveyor, making them complementary instead of competitors.
