Title: Polar Project Status October, 2002
1Polar Project Status October, 2002
2State 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.

3Status 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

6Ground 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
7Who 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.

8Long 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.
9Contracting 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
10Regarding 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.
11Summary
- 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.

14Review 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.
15Initial 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
16Initial 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
17Results 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.

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.

29Concerns 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.
30Mass and energy coverage of the Polar particle
instrumentation packages
