Introduction

A key science goal of the ARISE Space VLBI mission is the imaging of cores of gamma-ray blazars on scales of light months or less. This requires observations of moderate-to-high sensitivity at 43 and 86 GHz. In particular, it is desirable to be able to choose from a set of at least 100 detectable sources at 86 GHz. This memo addresses the resulting requirements on the mission sensitivity and the capability for detecting the desired number of sources.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
