Rosetta is an ESA mission, the first designed to both orbit and land on a comet. It will reach comet Churyumov – Gerasimenko in 2014. Rosetta’s ten-year expedition began in February 2004, with an Ariane-5 launch from Kourou in French Guiana. VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) and GIADA (Grain Impact Analyzer and Dust Accumulator) are two of the scientific payloads on-board Rosetta Orbiter with a fundamental italian contribution by INAF.
is the Visible, InfraRed and Thermal Imaging Spectrometer onboard the Rosetta spacecraft provided by the European Space Agency (ESA). VIRTIS will provide quantitative information on the composition of the solid materials on the nucleus as well as mapping their distribution on the surface, and of the gases and molecules present in the coma. VIRTIS was built by a consortium under the scientific responsibility of the Istituto di Astrofisica e Planetologia Spaziali of INAF, IT, which guides also the scientific operations. The consortium includes Laboratoire d’études spatiales et d’instrumentation en astrophysique of the Observatoire de Paris, FR, and the Institut für Planetenforschung of DLR, DE. The VIRTIS instrument development has been funded and managed by the national space agencies: Agenzia Spaziale Italiana (ASI), IT, Centre National dEtudes Spatiales (CNES), FR, Deutsches Zentrum fr Luft- und Raumfahrt (DLR), DE. The full Support from the Rosetta Science Operations Centre and the Rosetta Mission Operations Centre is gratefully acknowledged. The VIRTIS calibrated data will be available through the ESAs Planetary Science Archive (PSA) web site (www.rssd.esa.int/index.php?project=PSA&page=index
(Grain Impact Analyser and Dust Accumulator) on-board Rosetta measures the number, mass, momentum and velocity distribution of dust grains emitted from the cometary nucleus. GIADA was built under the scientific responsibility of a consortium led by the Università di Napoli “Parthenope”, IT, and INAF-Osservatorio Astronomico di Capodimonte, IT, in collaboration with the Instituto de Astrofisica de Andalucia, ES, Selex-ES s.p.a. and SENER. GIADA is presently managed and operated by Istituto di Astrofisica e Planetologia Spaziali of INAF, IT. GIADA development has been funded and managed by the Agenzia Spaziale Italiana ASI, IT, with a support of the Spanish Ministry of Education and Science MEC, ES. GIADA was developed from a Principal Investigator proposal supported by the University of Kent, UK; scientific and technical contribution was given by CISAS, IT, Laboratoire d’Astronomie Spatiale, FR, and many Institutions from UK, IT, FR, DE and USA. We thank the Rosetta Science Ground Segment at ESAC, the Rosetta Mission Operations Centre at ESOC and the Rosetta Project at ESTEC for their outstanding work. Science support was provided by NASA through the US Rosetta Project managed by JPL/California Institute of Technology. The GIADA calibrated data will be available through the ESA’s Planetary Science Archive (PSA) web site (www.rssd.esa.int/index.php?project=PSA&page=index
