SAFIR will: Study the important and relatively unexplored region of the spectrum between 30 and 300 m; Enable the
study of galaxy formation and the earliest stage of star formation by revealing regions too enshrouded by dust to be studied
by NGST; Be more than 100 times as sensitive as SIRTF or the European [Herschel] mission.SAFIR is projected to cost
around $600M total. The decadal review committee recommends that $100M be allocated in this decade to start the SAFIR
project, and that additional technology developments be funded separately: Far-Infrared Array Development ($10M )
Refrigerators ($50M ) Large, Lightweight Optics ($80M ). Current developments are also described.

Star and Galaxy Formation at High Redshifts: What is to be learned from Future Far-Infrared and Submillimeter
Observations

The observations relevant to the problem of star and galaxy formation at high redshift available at present are of three
types: the cosmic infrared background of radiation from all generations of stars and galaxies (see. Hauser & Dwek 2001
for a review); deep number counts of extragalactic sources from mid infrared to millimeter wavelengths (e.g. Elbaz et al. 2002,
Dole et al. 2001, Serjeant et al. 2001, Scott et al. 2002 and references therein); power spectra of the unresolved background
in the far infrared (Lagache & Puget 2000, Miville-Desch nes et al. 2002). Identifications and detailed studies of
individual sources at long wavelengths are coming very slowly. Partial redshift distribution starts to be available.

This paper represents the consensus view of the 124 participants in the Second Workshop on New Concepts for
Far-Infrared/Submillimeter Space Astronomy.We recommend that NASA pursue the vision for far-IR astronomy outlined in
the NAS Decadal Survey, which said: A rational coordinated program for space optical and infrared astronomy would build
on the experience gained with NGST1 to construct [a JWST-scale filled-aperture far-IR telescope SAFIR, and then ultimately,
in the decade 2010 to 2020, build on the SAFIR, TPF, and SIM experience to assemble a space-based, far-infrared
interferometer. SAFIR will study star formation in the young universe, the buildup of elements heavier than hydrogen over
cosmic history, the process of galaxy formation, and the early phases of star formation, which occur behind a veil of dust that
precludes detection at mid IR and shorter wavelengths. The far-infrared interferometer will resolve distant galaxies to study
protogalaxy interactions and mergers and the processes that led to enhanced star formation activity and the formation of Active
Galactic Nuclei, and will resolve protostars and debris disks in our Galaxy to study how stars and planetary systems form.
