We report the first detection and profile characterization of thermal
emission from the surface of Venus at 0.85 and 0.90 mum, observed
in the first planetary spectrum acquired by the Visual-Infrared Mapping
Spectrometer onboard the Cassini spacecraft en route to the Saturn
system. The strength and shape of these two newly observed nightside
emissions agree with theoretical predictions based on the strength
of the strong emission observed at 1.01 mum, These emissions, together
with previously-reported surface emission features at 1,01, 1,10,
and 1.18 mum, potentially provide a new technique for remotely mapping
the mineralogical composition of the venusian surface. (C) 2000 Academic
