The authors gratefully acknowledge the assistance and support of the entire MIRO project teams at the Jet Propulsion Laboratory, the Max-Planck-Institute for Solar System Research, and the Observatoire de Paris. It is not practical to list all of the people by name who have contributed to the MIRO instrument, but special acknowledgement is extended to the following persons: John Alpay, Pierre Bertram, M. Brunet(CNES), Beverly Drane, Benoit Germain, Timothy Ho, Gary Kinsella, Sonia Khatri, Peter Kobzeff, Ali Pourangi, and Jason Suchman. Claude Berner, Bodo Gramkow, Gerhard Schwehm and the entire ESA Rosetta Project team are thanked for their many contributions to MIRO. The work at JPL was supported by NASA.

N2 - The European Space Agency Rosetta Spacecraft, launched on March 2, 2004 toward Comet 67P/Churyumov-Gerasimenko, carries a relatively small and lightweight millimeter-submillimeter spectrometer instrument, the first of its kind launched into deep space. The instrument will be used to study the evolution of outgassing water and other molecules from the target comet as a function of heliocentric distance. During flybys of the asteroids (2867) Steins and (21) Lutetia in 2008 and 2010 respectively, the instrument will measure thermal emission and search for water vapor in the vicinity of these asteroids. The instrument, named MIRO (Microwave Instrument for the Rosetta Orbiter), consists of a 30-cm diameter, offset parabolic reflector telescope followed by two heterodyne receivers. Center-band operating frequencies of the receivers are near 190 GHz (1.6 mm) and 562 GHz (0.5 mm). Broadband continuum channels are implemented in both frequency bands for the measurement of near surface temperatures and temperature gradients in Comet 67P/Churyumov-Gerasimenko and the asteroids (2867) Steins and (21) Lutetia. A 4096 channel CTS (Chirp Transform Spectrometer) spectrometer having 180 MHz total bandwidth and 44 kHz resolution is, in addition to the continuum channel, connected to the submillimeter receiver. The submillimeter radiometer/spectrometer is fixed tuned to measure four volatile species - CO, CH3OH, NH3 and three, oxygen-related isotopologues of water, H2 16O, H2 17O and H2 18O. The basic quantities measured with the MIRO instrument are surface temperature, gas production rates and relative abundances, and velocity and excitation temperature of each species, along with their spatial and temporal variability. This paper provides a short discussion of the scientific objectives of the investigation, and a detailed discussion of the MIRO instrument system.
