MIRO MIRO (Microwave Instrument for the Rosetta Orbiter) is used to determine the abundances of major gases, the surface outgassing rate and the nucleus subsurface temperature. It will also measure the subsurface temperatures of Siwa and Otawara, and search for gas around them.   Principal Investigator: S. Gulkis, NASA-JPL, Pasadena, CA., United States.       Last update: 20 October 2004  •  Rosetta at a glance (http://www.esa.int/SPECIALS/Rosetta/SEMYMF374OD_0.html)  •  The Rosetta orbiter (http://www.esa.int/SPECIALS/Rosetta/ESAHVF7708D_0.html)  •  The Rosetta lander (http://www.esa.int/SPECIALS/Rosetta/ESAMXF7708D_0.html) Instruments on the orbiter  •  ALICE (http://www.esa.int/SPECIALS/Rosetta/SEMRHF374OD_0.html)  •  CONSERT (http://www.esa.int/SPECIALS/Rosetta/SEMUQ0474OD_0.html)  •  COSIMA (http://www.esa.int/SPECIALS/Rosetta/SEMCM0474OD_0.html)  •  GIADA (http://www.esa.int/SPECIALS/Rosetta/SEM0T0474OD_0.html)  •  MIDAS (http://www.esa.int/SPECIALS/Rosetta/SEMGO0474OD_0.html)  •  OSIRIS (http://www.esa.int/SPECIALS/Rosetta/SEMYCF374OD_0.html)  •  ROSINA (http://www.esa.int/SPECIALS/Rosetta/SEM5K0474OD_0.html)  •  RPC (http://www.esa.int/SPECIALS/Rosetta/SEMUV0474OD_0.html)  •  RSI (http://www.esa.int/SPECIALS/Rosetta/SEM101474OD_0.html)  •  VIRTIS (http://www.esa.int/SPECIALS/Rosetta/SEM28Q374OD_0.html) Instruments on the lander  •  APXS (http://www.esa.int/SPECIALS/Rosetta/SEMBU5474OD_0.html)  •  ÇIVA (http://www.esa.int/SPECIALS/Rosetta/SEMZU5474OD_0.html)  •  CONSERT (http://www.esa.int/SPECIALS/Rosetta/SEM2W5474OD_0.html)  •  COSAC (http://www.esa.int/SPECIALS/Rosetta/SEMPW5474OD_0.html)  •  MODULUS PTOLEMY (http://www.esa.int/SPECIALS/Rosetta/SEMDX5474OD_0.html)  •  MUPUS (http://www.esa.int/SPECIALS/Rosetta/SEMOX5474OD_0.html)  •  ROLIS (http://www.esa.int/SPECIALS/Rosetta/SEMIY5474OD_0.html)  •  ROMAP (http://www.esa.int/SPECIALS/Rosetta/SEMTY5474OD_0.html)  •  SD2 (http://www.esa.int/SPECIALS/Rosetta/SEM5Z5474OD_0.html)  •  SESAME (http://www.esa.int/SPECIALS/Rosetta/SEMGZ5474OD_0.html)
