Solar-B FPP 2 Ted Tarbell, TRACE Operations 3 February 2003 MODA Mtg, ISAS The TRACE Model for Operations TRACE Initial Phases Transition to Long-Term Operational Phase Why TRACE Remote Operations Works Tools for TRACE Planners & Monitors Science Coordination with Remote Planners Report on Other Missions by Dr. Chuck Holmes (NASA HQ) T. D. Tarbell, LMSAL tarbell@lmsal.com

3. Solar-B FPP 3 Ted Tarbell, TRACE Operations 3 February 2003 MODA Mtg, ISAS TRACE Initial Phase (1) Launch (2 April, 1998) to 1 st eclipse season (November, 1998) –April: 3 weeks outgassing, 1 week engineering checkout –May - June: 6 weeks to finish “Initial 30-Day Plan,” coordinated with SOHO –June – November: 5 months of observing without SOHO, refining observing programs and procedures, and training weekly science planners All Operations at GSFC Experiment Operations Facility –No instrument problems so engineering staff went home after ~1 week –2 scientists, 1 assistant, 1 computer sysadmin resident at GSFC –All other weekly planners traveled to GSFC for 7-10 day visits Science planning by telecons and lots of email –Daily telecons at first with LMSAL/SAO/MSU, then weekly –Simple coordinations with Yohkoh & ground based observatories

4. Solar-B FPP 4 Ted Tarbell, TRACE Operations 3 February 2003 MODA Mtg, ISAS TRACE Initial Phase (2) All science observing programs were completely rewritten in this period –Better types of sequences were developed, both for science and for calibration –Most preflight sequences were never used again Operations were difficult for the early planners –Only ~6 people had enough knowledge of the instrumdent to be a weekly planner, learning how to do it on the job –Much stress from daily deadlines and too many details to follow –When operations began to settle down shortly before eclipse season, we began to train new planners Science Planning & Operations in this phase were done with approximately the same approach as that of the Solar-B MODA Outline

5. Solar-B FPP 5 Ted Tarbell, TRACE Operations 3 February 2003 MODA Mtg, ISAS Transition to Operational Phase During 1 st eclipse season, planning software installed at LMSAL –Mirroring of planning data, ftp transfers of timelines and quick look data completely successful During 2 nd year of observing, 2 scientists, 1-2 assistant planners, 1 computer sysadmin resident at GSFC –Occasional visits by other scientists to be weekly planner –Frequent JOP’s with SOHO scientists at GSFC and in France After 2 nd year, no resident scientists, 1 part-time planner, 1 part-time computer sysadmin Most planning now done at LMSAL, SAO, MSU –Travel to GSFC is done by choice to interact with scientists there, not by necessity to do science planning & operations

6. Solar-B FPP 6 Ted Tarbell, TRACE Operations 3 February 2003 MODA Mtg, ISAS Why TRACE Remote Operation Works Science planning is done by email & telecon, even daily target selection Observing programs are always prepared in advance, and usually tested onboard before a JOP is run with other instruments Planning data (SAA’s, station passes, etc.) and quick-look telemetry is mirrored to multiple remote sites (LMSAL, MSU, SAO) Remote sites run same planning software as in GSFC EOF –Prepare observing tables & timelines, send to GSFC by secure sftp and ssh for uplink by the NASA satellite operators No normal Real-Time operations except uplink of timeline and tables People watch web displays of health & status at different places & times One part-time science planner at GSFC always on-call

20. Solar-B FPP 20 Ted Tarbell, TRACE Operations 3 February 2003 MODA Mtg, ISAS Science Coordination with Remote Planners TRACE has run successful joint observations not only with SOHO at GSFC but also with: –SOHO “MEDOC Campaigns” with planners in Paris –Ground-based observatories in the Canary Islands, Sac Peak & Hawaii –Yohkoh and ground-based observatories in Japan Campaigns must be scheduled well in advance Observing programs must be written and run on simulator in advance – Usually tested onboard by a short run a few days in advance All parties must understand & follow the timing constraints for target selection All email must go to trace_planner (NOT to an individual person) because several people follow it in addition to the weekly planner

23. Solar-B FPP 23 Ted Tarbell, TRACE Operations 3 February 2003 MODA Mtg, ISAS Comments on Observing Table & Timeline Generation Tools Need fast, local tools with intuitive GUI interfaces for use at ISAS Need ability for remote scientists to make & test observing tables before coming to or sending them to ISAS, using nearly identical tools Need developmental databases of observing tables and secure, “checked-in” database of observing tables approved for use in flight Need simulator or compiler to validate observing tables before they are “checked in” Access via the network for all of the developmental tools should be considered while designing the interfaces –Running locally using mirrored databases and/or running over the network, perhaps with reduced use of graphics to speed connectivity –Must guarantee adequate security, of course
