GIADA Grain Impact Analyser and Dust Accumulator Rosetta SWT #20 14-15 Sep 2006 @ ESOC GIADA Grain Impact Analyser and Dust Accumulator Instrument Status L. Colangeli (1), J.J. Lopez Moreno (2), and the International GIADA Team (I, E, UK, F, D, USA) (1) INAF - Osservatorio Astronomico Capodimonte - Napoli, Italy (2) Instituto de Astrofisica de Andalucia - Granada, Spain Osservatorio Astronomico di Capodimonte

General instrument status GIADA has participated to all commissioning / checkouts but PC3

General instrument status In–flight: nominal behaviour

Activities In-flight procedures and RSDB revised Preparation of PC4 (also to check “interference” effects with S/C and P/L) User Manual updating: completed Work on going to produce PDS data-sets

Team Status Team composition stable Staff members: 2 (INAF-OAC), 2 (Uni Parthenope), 2 (IAA) 2 contacts @ INAF-OAC (ASI Rosetta-GIADA contract) Industry activity ended Funding status 3 years contract from ASI (started July 2005) covering Institute activities => II milestone with ASI passed on July ‘06

Scientific Results GIADA does not produce scientific data during “cruise” Other scientific activities on going in the GIADA Team Laboratory simulations Cometary observations Stardust sample analysis Modelling Paper for SSR returned to Editor after (minor) revisions (“tentatively accepted”)

Scientific Results Cometary observations Program to observe (short period) comets at large heliocentric distance (imaging, spectroscopy) for studying onset of activity Several observation runs performed at various national and international telescopes Akari (ASTRO-F) program accepted (P.I.: Elena Mazzotta Epifani) E. Epifani et al., The dust coma of the active Centaur P/2004 A1 (LONEOS): a CO-driven environment, Astronomy and Astrophysics, accepted (2006)

Scientific Results Stardust sample analysis (P.I.: Alessandra Rotundi) Laboratories in Naples and Catania Morphology (FESEM), Composition (EDX), m-Raman and m-Infrared spectroscopy Several 10-20 mm particles analysed Papers in preparation Wrap up meeting in November

Open Issues Preparation of data-sets in PDS format Interference with S/C and other P/L to be clarified Stray-light effects vs. Sun position to be tested again Clean room ready @ INAF-OAC for installation of the GIADA Spare model => support to operations and further tests on real dust “Fate” of EQM
