7. PDS 2010 Support • Participating as requested in various activities • Level is rather small, but apparently adequate • Design seems ok so far regarding SPICE • One small change being worked by EN/NAIF • Status of new core SPICE capabilities that might help with future PDS 2010 services • Java Native Interface to SPICE (JNISpice) • Could make building modern PDS tools (“geometry engine”, etc.) easier to build • Alpha-test version is out in the community now • Geometry finder subsystem • Substantial capability available in current Toolkit (N63) • A bit more to be added in next Toolkit release

8. Other Items • IPDA Ancillary Data Project • Not sure if this could/should move forward • Not too much interest; folks are busy with other items • Perhaps just maintaining the status quo with regard to ancillary data (i.e. no “project”) is best? • SPICE Training • Recent classes held in Tokyo*, Pasadena, Madrid* • Moscow training coming up in May (using PhSRM funds) • The NAIF team now believes major changes are needed • Separate tutorials for individual use versus those presented at classes • More extensive/meaty “hands-on” programming lessons • If doable, provide three different classes: • Beginners (for consumers) – a simplified version of the current class • Kernel producers • Advanced (for consumers and producers) * Travel costs reimbursed by JAXA and ESA, respectively

12. Questions for NAIF’s Advisory Board(That’s you!) • What problems have you discerned, or heard of… • regarding Core SPICE Development? • regarding NAIF Node Operations? • Are SPICE Development and NAIF Node Operations appropriately integrated into the PDS enterprise • Where might improvements be made? • What are your recommendations for modification to NAIF’s plans for future work*… • regarding Core SPICE Development? • regarding NAIF Node Operations? * NAIF can provide more details on planned work to anyone interested in this.

15. SPICE works quite well Used by all NASA planetary missions Adopted by many non-planetary missions Adopted by all major foreign space agencies Hundreds of users Very few bugs/errors Very few complaints Principal complaints Substantial learning curve NAIF is slow to provide: new language interfaces new supported platforms new capabilities NAIF does pretty well SPICE data archives are on time, correct, complete, and well documented Customer support is excellent Lots of use of the web pages and NAIF server Very few complaints Principal complaints Need to offer more kinds of focused classes Classes should have less lecturing, more student programming Can be hard to select needed data file(s) (This applies more to mission operations data than to archived data) NAIF’s Perception of Customer’s Opinions Based in part on customer emails and face-to-face discussions Core SPICE Development NAIF Node

16. Our work lists are long and getting longer Maintaining all we offer is very time consuming lots of code lots of languages lots of platforms lots of documents and will become more so as we continue to add new capabilities, new languages and new platforms. Some non-JPL NASA projects are unprepared to produce good and complete SPICE data sets The current central catalog interface to archived SPICE data does not work well Preparing for and conducting training classes takes a great deal of effort–principally because SPICE continues to evolve Helping users takes a good deal of time, especially for those who are neophytes or are in a hurry If/when/how to deal with foreign planetary missions remains largely a mystery Need to finish ancillary data restorations NAIF’s View of Its Challenges In addition to the issues noted on the previous chart… Core SPICE Development NAIF Node
