1. OSIRIS operation summary
Operations since last team meeting:
Software update and (failed) active checkout Dec. 2006
Lutetia Observations in Jan. 2007
Mars Swingby Feb. 2007, followed by Jupiter observations
Passive checkout May 2007
Active checkout ongoing now
Busy period of 10 months
Next major events:
Earth flyby 13 Nov. 2007
Steins flyby Sept. 2008
Both preceded by an active checkout

Total (mission)
7920

3. Active checkout and software update
Phase 1: Observations of Mars before software update
Nice images of Mars with Milky way
Most other images do not point on Mars
Software update
Successful
Active checkout after software update
Failed due to software anomaly (DIB crash) unrelated to the update

4. Mars image (WAC Red and Green filters)
Note the nice ghost image of overexposed Mars

5. Software update More flexible operating with Monitoring sequence
Better image compression algorithm
Includes lossless compression
Introduction of software windowing
Bug fixes

6. Failure of phase 3
DIB crash in the very first telecommand after the software update (TestMMB)
New variant of old problem
Not completely understood, but workaround is known
Workaround was not implemented in TestMMB
Short term solution: Remove TestMMB from passive checkout sequence
Mid term solution: Implement workaround in TestMMB during the next software update
Positive effect: Successful test of the safety net!
OSIRIS was switched-off by the spacecraft

7. Lutetia Observations
Supporting observation in preparation of the flyby
Made it into the plan together with Steins obs. from March 2006
Lightcurve was measured with both cameras and in seven filters with the NAC ( nm)
Additional full frames with 4 filters of each camera for calibration

8. Light curve of Lutetia Several team members worked on the light curve
Example provided by P. Lamy
Good consistency between different filters
Some results were presented in Science session

9. Mars swing-by First in situ observation with OSIRIS
Earth swing-by 1 was lost in 2005
Severe restrictions on operations
Large solar elongation allowed four hour slot only before closest approach
Solar eclipse required switch-off around closest approach
Night side of Mars observed at low solar elongation after closest approach

10. Mars Cameras produced excellent images during approach phase
Some issues with the NAC shutter
Long observations to search for dust ring, atmospheric emissions and gas clouds were mostly overexposed
In-field straylight was underestimated in the planning process
Straylight investigation is ongoing (talk by G. Naletto)
No Science talk about results from the Mars flyby on this meeting!
We need to discuss how to proceed
Can we exploit synergies with VIRTIS data?

15. Jupiter Observations Jupiter was observed shortly after the Mars flyby
Driven by ALICE (remote support for New Horizons flyby of Jupiter)
OSIRIS participated only during the first few hours
Mainly for calibration
A few long exposures on Na cloud and plasma torus

16. Jupiter NAC Data are still to be analyzed Ghost of Jupiter Jupiter Io
Ganymed
Europa
Callisto

17. Passive checkout Nominal performance of the cameras
WAC star field (512 x 512 pixels)

18. Targets observed with OSIRIS so far
3 comets
LINEAR 2002 T7
Machholz 2004 Q2
9P/Tempel 1
Asteroid 21 Lutetia and 2867 Steins
Several stars
Eps. Aqr, 58 Aql, Vega, 16 Cyg, alpha Gru
Starfield for geometric calibration (area 98)
