NASA's Far-Infrared/Submillimeter Roadmap MissionsInformation vital to the attainment of the major scientific objectives of NASA s Origins and Structure and Evolution of the Universe themes is uniquely available in the far-IR and submillimeter (FIR/SMM). NASA is studying concepts and investing in technologies for FIF/SMM telescopes that could fly in the decade 201 0 - 2020 and provide enormous increases in measurement capabilities to extend the legacy of the next-generation missions SlRTF and Herschel. Future FIR/SMM space observatories will have the sensitivity needed to reach back in time to the formation epoch of the first luminous objects, the angular resolution needed to image proto-planetary systems and distinguish the emissions of individual galaxies, and the spectral resolution needed to probe the physical conditions and measure the flows of interstellar gas in young galaxies, nascent stars, and the dust-enshrouded nuclei of galaxies that harbor massive black holes. NASA s infrared roadmap includes the JWST-class Single Aperture Far-IR (SAFIR) telescope and FIR/SMM interferometers. The talk will give the scientific motivation for these missions, describe mission concepts and telescope measurement capabilities, and compare these capabilities with those of the next-generation IR telescopes and with the complementary JWST and ALMA.
