  1. The Long Range Plan: Cycle 17 updateSeptember 2009Dave Adler

  2. Current state of the LRP • SMOV not included in totals. • Some programs have more than one SI prime. cycle 17 cycle 17 tail TIPS – LRP – 17 September 2009

  3. How the Operational LRP was built • Cycle 17 runs from August 17, 2009 – Sept 1, 2010 • Aimed for 80 orbits/week - historical 3-Gyro average • Resulting plan has 10.19 orbits/day in the cycle • including “unplanned” visits adds 1.21 orbits/day • 11.4 orbits/day  80 orbits/week – full subscription • Cycle 17 tail (post-9/1/10) includes 830 orbits • Early priorities in the LRP - from HSTMO: • SMOV – most pre-cycle, butsome planned in cycle • EROs – most pre-cycle • ERS – 2 programs, 214 orbits • finish c15/16 – currently planned: 348 orbits • GTOs early, if possible – ~300 orbits • cals early, as needed • keep programs together when possible TIPS – LRP – 17 September 2009

  4. Early Cycle 17 issues • SMOV additions/delays caused the start of the cycle to be heavily oversubscribed. • 410 orbits of SMOV/science/cals in first three weeks! • Solution pushed some things later in cycle: • some COS, NIC SMOV was delayed • some ERS targets were delayed • some high-priority GO science was delayed • Why are so many Cycle 17 plan windows late? • early priorities forced some C17 GOs to be planned late. • need to account for “unplanned” visits (ToO, HOPRs, etc) throughout the cycle. • some DD demand for early orbits – Jupiter, Comet, LCROSS, etc. • SMOV/ERS-induced “bow-wave” didn’t help issue. TIPS – LRP – 17 September 2009

  5. It could get worse… • Some “unplanned” science is now entering the plan: Chandra-coordinated science (~100 orbits), ToOs, HOPRs, etc. • On-going SI issues require some plan rework: • COS FUV planned for the current time frame could move later. • When NIC is ready for GO science - visits will be pulled forward when possible. • WFC3 “hard” science will soon be enabled. TIPS – LRP – 17 September 2009

  6. …before it gets better • Early results: weekly orbit counts are encouraging • first few post-SMOV flight calendars were packed: • Caution with these early results: • We’ve not yet been in a northpoint week. • fewer SAA-hiders can schedule, subscription will be lower. • Early-cycle subscription is always higher: greater visit selection; highly-flexible visits are still available. • If high-subscription trend continues: • We can pull visits in the tail earlier. • Will evaluate after northpoint weeks are scheduled.
