2. Team Status Last Science Team mtg. in Venice in Sep. 2007
Next mtg. in October 2008 after Steins flyby
4 OSIRIS working groups on calibration, asteroids and fly-bys, coma, and nucleus
Next meetings of calibration and fly-by WG in January 2008
Calibration pipeline set up including geometric corrections of both cameras
Analysis of MSB data (calibration and science) is still going on

4. Instrument Operations
Passive Checkout (PC5) - May 2007
No problems
Active Checkout (PC6) - Sep 2007
WAC no specific problems
NAC shutter stability problem
Problem of software with memory handling
uncontrolled stop of normal thermal control
weakness in high level (UDP) memory handling found
requires low level software change
Earth Swing-By #2 - Nov 2007
Temporary work around of memory problem implemented
Only very limited NAC operation
WAC and NAC no problems
OSIRIS

5. Instrument Status Both cameras working
Some shutter errors during operations
NAC in particularly (blade locking errors)
Stray light in field of view and near field of view under investigation based on MSB and additional Earth flyby data
OSIRIS

6. NAC Shutter Problem
Two overall problem areas:
NAC Shutter mechanical stability (parameter space drift)
Solution:
Implementation of a background continuous tuning algorithm
Relaxation of shutter safe mode criteria
General electronics problem (type D error condition)
Origin of problem now found (1.6 ms window in 870 ms cycle of shutter electronics FPGA where logic break down occurs)
Workaround for problem under development
A major team effort started to solve the shutter problems. First major success is the understanding of error type D
Target deadline – Early Feb test and update slot
OSIRIS

7. Earth – Moon Observations
OSIRIS operations only during early approach (> 20 min before CA)
No operations while within radiation belt
Limited NAC operations
Earth day side images from 106 km
Several images useful for PR (web page)
