  The Single Aperture Large Telescope for Universe Studies (SALTUS) is a
deployable space telescope designed to provide the astrophysics community with
an extremely large far-infrared (far-IR) space observatory to explore our
cosmic origins. The SALTUS observatory can observe thousands of faint
astrophysical targets, including the first galaxies, protoplanetary disks in
various evolutionary states, and a wide variety of solar system objects. The
SALTUS design architecture utilizes radiatively cooled, 14-m diameter
unobscured aperture, and cryogenic instruments to enable both high spectral and
spatial resolution at unprecedented sensitivity over a wavelength range largely
unavailable to any existing ground or space observatories. The unique SALTUS
optical design, utilizing a large inflatable off-axis primary mirror, provides
superb sensitivity, angular resolution, and imaging performance at far-IR
wavelengths over a wide +/-0.02 x 0.02 degree Field of View. SALTUS design,
with its highly compact form factor, allows it to be readily stowed in
available launch fairings and subsequently deployed in orbit.
