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.
  • At ecliptic normal, despun platform control and
    auroral viewing is limited to an 4.5 hour
    segment of each 17 hour orbit.

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.
  • Polars 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 45min earlier in local time in the
    north.
  • A JGR special section on "Causes of the Aurora"
    will appear soon.

thermal plasma, accelerated by circularly
polarized waves, is regularly seen in the dayside
boundary layers
More than ten "great" conjugate events have been
captured including this substorm onset on 1 Nov
2001

Ground Data ProcessingWhat 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

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.

Long Term Funding Profile
  • The PWG infrastructure held within CSOC has
    decreased dramatically over the past year. Some
    CSOC cost estimates for FY03 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.

9
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 Status
Direct contract with Honeywell Waiver of requirement for transfer to educational or research related location Direct contract not permissible w/o extended competition cycle ID/IQ, permission to add task to MIDEX ID/IQ or start new ID/IQ Preferred method currently pursuing ID/IQ and waiver.
Contract with educational or research location May want waiver on 6-month pull-out requirement Contractual and management layer between NASA and MO team USRA and Capital College are willing
Remain with CSOC Uncertainty regarding post-CSOC Operations reliability and safety Changes remain costly and slow Negotiations continue with regard to cost and staffing levels
10
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
  • MODA contract mechanism that allows appropriate
    control over PWG re-engineering.
  • Small augmentations to team funding for specific
    data processing/accessibility tasks.

11
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. FY02
    funding was, on average, 90 of FY01 levels.
    Funding profiles for FY03 are budgeted at FY02
    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.

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 TM
    programs
  • providing extensive data and media integrity and
    quality services.

15
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
  • QuickLook 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
16
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_25Jun02.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
    McGuire
  • 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

17
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.

Unattended Spacecraft Contacts for Data Playbacks
Current
Proposed
6-8 console operators, covering 24x7, typically 4
shifts of two operators, Wind 1 contact/3
days, Polar 4 contacts/day, All attended contacts
4 console operators, covering 16x5, Wind 1
contact/3 days, Polar 3-4 contacts/day, TBD
number of unattended contacts
  • Notes
  • Fewer attended contacts/fewer double attended
    contacts may mean less convenient or delayed
    command scheduling.
  • Errors at DSN sites will mean result in several
    hours of data loss for Polar and several days of
    data loss for Wind.

Concerns on the Project Side
  • With Respect to Mission Operations
  • Can we find a contractual environment for
    operations that is affordable and legal?
  • Can the re-engineered system collapse to an
    affordable Wind-only environment after Polar and
    Geotail end of missions.
  • What is the minimum data recovery percentage
    acceptable in light of fiscal constraints imposed
    on extended mission programs.

Mass and energy coverage of the Polar particle
instrumentation packages
Polar remains the best instrumented spacecraft in
the magnetosphere.
31
Exploring the Sun-Earth System
  • An alliance of solar, heliospheric and geospace
    missions for the coordinated study of Sun-Earth
    system dynamics.

32
Alliance Objectives
  • The SEC Alliance of spacecraft will expand the
    scientific productivity of the individual
    missions by fostering joint scientific analyses
    of phenomena that originate at the sun, propagate
    through interplanetary space, and impact the
    Earth's magnetosphere and upper atmosphere.

Targeted objectives include Understand the
coronal causes of heliospheric disturbances
Determine the evolution of disturbances within
the heliosphere Understand the coupling of
solar wind energy to geospace Understand the
coupling of energy from the magnetosphere into
the atmosphere
33
Alliance Activities
  • Sponsor analysis campaigns focused on specific
    science problems that bridge mission objectives.
    To date
  • Energy transfer across the dayside magnetopause
    and through the cusp
