Polar Project Status October, 2002 Robert Hoffman/Polar Project Scientist Barbara Giles/Polar Deputy Project Scientist
State of the Spacecraft • The Polar spacecraft and instruments are healthy. Only the plasma wave instrument and the MICS sensor portion of CAMMICE have suffered major faults; PWI now operates only during eclipse. • Polar has initiated semi-annual attitude maneuvers to extend orbit normal operations for auroral imaging and optimize fuel usage. March 18, 2002 – half flip to ecliptic normal Fall 2002 – half flip to orbit normal Spring 2003 – full flip to orbit normal for southern winter auroral viewing Fall 2003 – half flip to ecliptic normal (permanent) • At ecliptic normal, despun platform control and auroral viewing is limited to an ~4. 5 hour segment of each 17 hour orbit. CAMMICE, CEPPAD, EFI, HYDRA, MFE, PIXIE, PWI, SEPS, TIDE, TIMAS, UVI, VIS PWG Project Status / 23 October 2002 Pg 2
Status of the Science • Polar completed a prolonged observation campaign through the dayside equatorial magnetopause region with unprecedented high-temporal and spatial resolution. Now conducting a similar campaign across the nightside equatorial magnetosphere. • Polar, IMAGE, Cluster, Wind and Geotail will hold a collaborative workshop on the dayside magnetopause and cusp at Yosemite in Feb. 2003. thermal plasma, accelerated by circularly polarized waves, is regularly seen in the dayside boundary layers • Polar’s auroral science progressed to studies of the conjugate aurora. Some initial findings: – Onset brightening first seen in southern hemisphere with northern hemisphere onset detected ~1 min. later – Expansive phase brighter in southern hemisphere but located ~45 min earlier in local time in the north. • A JGR special section on "Causes of the Aurora" will appear soon. More than ten "great" conjugate events have been captured including this substorm onset on 1 Nov 2001 PWG Project Status / 23 October 2002 Pg 3

Ground Data Processing: What was Lost? What was Gained? With respect to Polar, Wind and Geotail, all data services previously required from the ISTP/CDHF and ISTP/SPOF have been retained. • ISTP services no longer provided: – systematic collection of data products from associated missions – KP CD distribution (impact is to Russian and South American data repositories) – dedicated program assistance center – off-hours data processing or problem response – automated data pushing to clients – quality control services of the ISTP/CDHF – problem response and quality control services of the ISTP/SPOF • Services improved: – open ftp access to the full data set – HTR data produced in addition to KP, software easily updated – automated processing brings faster turn around of products PWG Project Status / 23 October 2002 Pg 6
Who Gets the Credit: The Ground Data Processing Re-engineering team The success of the re-engineering effort is due to the cooperative efforts of several groups at GSFC who provided full- and part-time programming, system admin, design and management expertise. With specific tasks & consulting by: The core team: 587 Jim Byrnes 587 Chris Howard 696/583 David Berger 423 Jeff Lubelczyk 587 Ryan Boller 632 Rick Burley 587 Marlo Maddox 632 Tami Kovalick 632 Natalie Jaquith 690 Sandy Kramer contr.

Long Term Funding Profile • The PWG infrastructure held within CSOC has decreased dramatically over the past year. Some CSOC cost estimates for FY 03 do not reflect this decrease. • Conducting future mission operations under the current contracting mechanism does not appear to be economically feasible under the current long term funding profile. PWG Project Status / 23 October 2002 Pg 8
Contracting for Future Mission Services A six-month NOI to remove mission operations services from the CSOC contract was submitted. Arrangements for continued operations are being actively pursued. Option Roadblock Issues Waiver of requirement 1. Direct contract not permissible Direct contract for transfer to w/o extended competition cycle with educational or 2.

Uncertainty regarding post. CSOC 3. Operations reliability and safety 4. Changes remain costly and slow Negotiations continue with regard to cost and staffing levels Pg 9
Regarding Data Availability • ISTP required special event archiving, rather than the full data set, as has become common with recent missions. Data accessibility was the responsibility of the project. • Many Polar instrument teams have adjusted their data archiving and accessibility as is possible within their IT infrastructure and funding. – Continuous HTR data from PWI, TIMAS, and TIDE. CAMMICE and CEPPAD soon. – TIDE, PWI and MFE provide interactive data processing via the web. • Additional progress can be made over the next year: – HYDRA has HTR data software, needs to convert format to CDF. – UVI, VIS and PIXIE could archive continuous HTR rather than events. – MFE should update IT infrastructure and/or PWG project should produce MFE KP. – PWG project should create and host software library for access to LZ – PWG project could encourage and/or host additional interactive data processing. • Progress depends on: – MO&DA contract mechanism that allows appropriate control over PWG re-engineering. – Small augmentations to team funding for specific data processing/accessibility tasks. PWG Project Status / 23 October 2002 Pg 10
Summary • The Polar spacecraft and instruments are healthy. • Science progress over the past two years has been particularly robust. Prospects for further breakthroughs with respect to substorm and reconnection physics appears very strong. • Science funding has been relatively stable. FY 02 funding was, on average, 90% of FY 01 levels. Funding profiles for FY 03 are budgeted at FY 02 levels. • The new mission operations and ground data processing systems are operating and serving the science community well. Several important re-engineering tasks remain to be completed by the end of December 02. • Conducting future mission operations under the current contracting mechanism does not appear to be economically feasible under the current long term funding profile. • A six-month notice, effective Sept. 30, for discontinuation of CSOC services was submitted. • Arranging for an alternate contracting mechanism for mission operations remains difficult. Several avenues are being pursued. • A plan to implement additional data accessibility improvements is under development. PWG Project Status / 23 October 2002 Pg 11

Review of the ISTP Data System (an independent entity to serve the worldwide SEC community) In addition to • data processing and distribution services for GGS (Polar, Wind, Geotail) & IMP-8, • data distribution services for SOHO and Cluster, • operations and science coordination, ISTP served as a one-stop data source by • consolidating and distributing data for 15 additional spacecraft, observatories and T&M programs • providing extensive data and media integrity and quality services. PWG Project Status / 23 October 2002 Pg 14
Initial Courses of Action • The ISTP project office was disbanded and reduction of past ISTP activities occurred during October and November of 2001. • ISTP ground system services immediately reduced were: – Quick. Look data processing for special requests only, – key parameter CD distribution reduced from ~12, 300 to 156 per year, – no key parameter re-processing, – no key parameter software updates, – no ground based or collaborative mission data processing or ingestion, – no dedicated program assistance center, – no system software updates excepting security patches, – no test or development environment, and – no off-hours data processing or problem response – services of the ISTP SPOF and Command Management System were consolidated with the MOC and the project scientist's office. Note: Items in blue have been restored within the new PWG data processing environment PWG Project Status / 23 October 2002 Pg 15
Initial Courses of Action • Contacted instrument teams regarding requirements for various operations and data services. • Produced prioritized requirements document for Polar, Wind and Geotail. (available at http: //tide. gsfc. nasa. gov/studies/POLAR/Polar_Ops_specs_25 Jun 02. pdf) • Conducted six feasibility studies for alternative approaches 1) the present ground system management under CSOC (2 studies) 2) SPDF at GSFC under the direction of Bob Mc. Guire 3) LASP at U Colorado under the direction of Bill Peterson 4) UC Berkeley under the direction of Bob Lin 5) the NSSTC under the direction of Dennis Gallagher PWG Project Status / 23 October 2002 Pg 16
Results of Feasibility Studies The following conclusions and actions resulted from the review of the studies: • More software and system re-engineering needed to be pursued than provided for by the CSOC/CDHF study and CSOC estimates for flight operations. • Eight re-engineering projects were identified to reduce the number of FTEs by three-quarters. • The re-engineering work should be performed under local control. • The UC Berkeley capabilities for hosting mission operations remain of interest. It was determined that a consolidation of all systems under the PWG Mission Operations Center (MOC) under an ID/IQ contract, as suggested by the SPDF study, offered the most cost effective solution with the least disruption to flight operations and the least risk to spacecraft health and safety.
