1. OSIRIS Full Team Meeting Welcome, Introduction, Logistics
Holger Sierks
Max-Planck-Institut für Sonnensystemforschung

2. OSIRIS - Scientific Camera System
NAC – Narrow Angle Camera
FOV 2.2°, IFOV 18.6 µrad/px
SiC, 2k x 2k BI E2V CCD, AB
3-mirror off-axis, f/8, 717mm
WAC – Wide Angle Camera
FOV 12°, IFOV 101 µrad/px
Al bench, 2k x 2k BI E2V CCD, AB
2-mirror off-axis, f/5.6, 140mm
plus 3 E-Boxes
(35.6 kg total)
22 % of Rosetta p/l

3. Overview OSIRIS: 15.5 months of prime mission by now in operation
6 months to end of nominal mission (at 2 AU outbound), mission 9 months extended
OSIRIS is healthy and in good shape (fingers crossed)
Statistics: NAC images, WAC images taken since 20 March 2014
Door cycles per camera: NAC 3.040, WAC 4.050
door open time: NAC total of 5 days 11:22h; WAC total of 12 days 02:10h
Filter-wheel moves to date: NAC , WAC (filter-to-filter changes)
OSIRIS cameras are at 2/3 of the lifetime usage (wrt consumables)
3 Science papers, 18+ A&A papers, 1+1 Nature paper, working A&A wave 2
Intensify x-team interaction on science planning, campaigns, & science data analysis
Need to go close for detection and monitoring of surface changes, link to activity
Issues: NAC curtains, WAC shut down, memory overruns, doors, filter wheel WAC
Need to find out about dust on mirrors!
Calibration issues: stray light infield, out-of-field, deconvolution algorithm worked
Team at its limits on planning and data verification

4. Technical Issues Open NCRs:
#229 NAC CRB HK out of limits for one short phase
#230 OSIRIS requested LCL off by PCM HK limit violation
#231 WAC door failure in closing (2 by now)
#232 NAC door failure in closing
#233 WAC Filter Wheel #1 position readout
and
/ shutters NAC & WAC (parameter/performance tunes)
/ memory overruns (o/b software issue on compression, queuing)

5. NAC Curtains
February and May 2015: Total of 36 images

6. WAC Unlocking Errors
> 500 errors in April/May (STP ), -> 1 week shut down

7. Logistics Meeting is 2.5 days
Team dinner: Reservation in Sambesi on Wednesday at 20:00
(Dutch treat)
Support: Fee von Saltzwedel, ext. 267
