Abstract: 
The Antarctic Submillimeter Telescope and Remote Observatory (AST/RO) 
has been operational at the South Pole since January 1995.  Preliminary
results include site testing and observations of atomic carbon in
PDR regions, high-latitude translucent clouds, the galactic center
and the Magellanic Clouds.  A off-axis 10-meter telescope will be proposed 
to the Office of Polar Programs as a user-facility instrument for
wavelengths between 200 microns and 6 millimeters.  Given the climatic
conditions at Pole, this instrument will have a data acquisition rate
two orders of magnitude faster than comparable instruments at Mauna Kea.
This will enable programs in observational cosmology.  The 100 micron
dust continuum  radiation and the far-infrared cooling lines of the
ISM in newly-collapsed and disorganized galaxies at high redshift 
emit most of their luminosity at wavelengths observable with this 
telescope.  Measurement of CMBR anisotropies at arcminute and smaller 
scales need to be made at short (2 mm) wavelengths in order to
disentagle the Sunyaev-Zel'dovich effect from any intrinsic anisotropy.
