concentration) as a function of depth and as a function of ro-
tational phase over the surfaces of numerous objects. Such
measurements will provide a wealth of data for constraining
cosmochemistry models of the outer Solar System. Finally,
the Atacama Large Millimeter Array (ALMA), a configura-
tion of about sixty-four 12-meter antennas located at an ele-
vation of 16,400 feet in Chile, may reveal extra-solar Kuiper
Belts for comparison with our Kuiper Belt. ALMA may pro-
vide density and temperature profiles as well as chemical
measurements through the detection of spectral lines in
the belts. ALMA may initiate a new field of study, compara-
tive Edgeworth-Kuiper Belt object ology, i.e., comparative
EKO-logy.Bibliography
