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

3. General instrument status
In–flight: nominal behaviour

4. 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

5. Team Status Team composition stable
Staff members: 2 (INAF-OAC), 2 (Uni Parthenope), 2 (IAA)
2 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

6. 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”)

7. 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)

8. 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 mm particles analysed
Papers in preparation
Wrap up meeting in November

9. 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 INAF-OAC for installation of the GIADA Spare model => support to operations and further tests on real dust
“Fate” of EQM
