1. UVIS Team Meeting Berlin 2009 Saturn and Titan Planning Bob West Working with Don Shemansky

2. Cassini Equinox Mission (XM) - Titan Solar and stellar occultations EUVFUV Images of Titan HDAC Riders with CIRS and ISS in T66 and T67 – Pascal Hedelt will do the analysis UVIS PRIME Requests T55-T61.ppt

3. Titan Stellar Occs – Prime + XM Number refers to table of occultations 1-12 in Prime mission, 13-20 in XM Also indicated are Latitudes (dashed) Altitude contours

4. XXM (Solstice Mission) Plan Saturn TWT activity for UVIS Identify solar and stellar occ opportunities (now evaluating 7A) Conflict exercise to indicate over-subscription and conflicts (done) Identify PIE (Pre-Integrated Events) opportunities PIE assignments identification – done for the ‘Bridge’ segment, to come for the rest of the XXM Segmentation with no liens Templates for apoapse and fill in the rest of periapse TOST activity for UVIS Identify solar and stellar occ opportunities (done) ‘Jumpstart’ meeting to decide who controls +- 2 hours from closest approach (took place at APL in mid-April) Additional meetings to decide on template activity outside of +- 2 hours, plus input to PIE process plus disposition of T119 C/A (INMS vs. RSS)

5. Bridge Sequence – Prelude to XXM Observations for July – September 2010 Each working group requested a set of PIEs Three meetings were held to adjudicate Saturn WG requested one solar occ out of three opportunities - two were obtained during the negotiations (Ingress and egress on rev 138; only one was a PIE) Process worked well in terms or rapid decision making

6. XXM Saturn Stellar Occ Opportunities in SM-7 Key BP = Bright star in periapse BA = Bright star in aoapse FP = Faint star in periapse FA = Faint star in apoapse Slower/brighter events have larger symbol sizes Goal: Obtain good latitude coverage

8. Tour 7a Titan Solar Occs

9. What We Must Do Next Check Titan solar and stellar occ opportunities for tour SM-7A Plan and request EUVFUVs and riders for Titan Identify solar and stellar occ opportunities for CSM (XXM) for Saturn – Communicate these to and interact with Saturn TWT Identify and quantify template activities like system scans, EUVFUV, auroral scans – any others?

10. System Scans Need a Home Which group (Mag or Saturn) should take charge of system scans? – Neither wants to do it – system scans are viewed as a large resource request in competition with other requests favored by each group – My recommendation: provide an incentive by offering extra revs to the group that takes it Leads need to know the details of the request (time, data volume, turns) and how it can be ‘templatized’

11. General Issues for the XXM Dwindling resources – Diminished workforce in the XXM Templates in apoapse periods Less dense planning in both periapse and apoapse Segments are mostly for one discipline with few intruding PIEs from other disciplines – RBOT issues Diminished turning and limited options for secondary axis How to plan? – Diminished power due to RTG half life More instruments going to sleep
