The principal science objectives of the major new telescope initiatives at radio, millimeter and sub-millimeter wavelengths are shown to correspond in large measure with the major science objectives of the new space astronomy observing facilities. The complementary insight that is achievable using combinations of these instruments is emphasized. It is noted that in most cases, these science objectives involve a discovery space based on a large sample of objects or of a particular large area of sky. In order to optimize the science return of each new telescope it is argued that the "design" of the science program for that telescope would benefit if it were done in concert with that of other contemporary telescopes.
The Millimeter Array (MMA) is a synthesis imaging telescope designed to provide sensitive, high-precision astronomical imaging at sub-arcsecond, 0'.1, resolution at millimeter and submillimeter wavelengths. In order to achieve these goals it is necessary to locate the Millimeter Array on an extremely dry site so as to minimize the atmospheric background emission; the receiver noise temperatures should be near the limit imposed by photon noise and the antenna warm spillover contribution should be minimized. It is possible to quantify each of these requirements, and the interactions among them, so as to achieve the maximum sensitivity for the Millimeter Array. Together, the requirements lead to the technical design goals for the Millimeter Array.
