PROBLEM / ISSUES PROGRAMMATIC
IMPACT ACTION
G

• Codes 400 and 500 are discussing ways to contain
  this problem
• Expedite thermal performance evaluation of
  optical system
• Conduct overall ICESat development and personnel
  assessment.
• Develop revised mission schedule

• Latest GLAS completion schedule causes impact to
  LRD.

• GLAS component rework cycles continue to erode
  GLAS integration and test schedule longer GLAS
  integration effort needed
• GLAS CPT only partially completed. Some problems
  under investigation. Instrument scientists
  struggling to interpret the data.

• CURRENT STATUS
• GLAS on proposed re-plan schedule for June 17
  delivery and subsequent 12/16 LRD. Schedule to
  be presented to HQ / Code Y in mid-March.
• Launch manifest indicates NET 12/19/02 LRD
• GLAS remains on schedule for June 17 delivery.
  Code Y PMC rescheduled for May 3. CLOSED

GLAS IT PROBLEMS IN WORK OPTICAL PATH ICESat
Project STATUS AS OF 3/31/02
DATE ESTAB COMPL 11/30
6/15
PROBLEM/ISSUES PROGRAMMATIC
IMPACT ACTION
Y
GLAS boresite stability does not meet mission
performance requirements
Fundamental measurements may be compromised if
behavior persists on orbit.

• Hold mini-peer review on calibration results
• Get AETD and systems involvement in development
  of troubleshooting plan.

• CURRENT STATUS
• Peer Review held
• Retest conducted preliminary results look
  favorable with major errors traceable to set-up
  issues. Detailed data analysis results look
  promising.
• Additional analysis initiated on the telescope
  assembly.
• Test plan defined.
• Plan in place to validate requires completion of
  environmental test program.

GLAS IT PROBLEMS IN WORK LIDAR OPERATION ICESat
Project STATUS AS OF 3/31/02
DATE ESTAB COMPL 12/17 6/15

PROBLEM/ISSUES PROGRAMMATIC
IMPACT ACTION
Y
Intermittent energy monitor on green laser
Potential compromise on Etalon operation and data
reduction

• Investigate root cause
• Investigate alternate means for Etalon operation
  and data reduction

• CURRENT STATUS
• Several troubleshooting tests conducted,
  inconclusive results.
• Alternate Etalon operation algorithms in
  development.
• Problem understood and board modification
  solution verified on the engineering model board.
  Alternative (baseline) software approaches being
  investigated and validated.
• Software fix to be validated in T / V testing

PROBLEM / ISSUES PROGRAMMATIC
IMPACT ACTION
Y

• Present overguide requirements to Code Y.
• Generate cost / schedule impacts
• Pursue budget approval through POP-02 process.

• Cannot meet late 2002 LRD without additional
  funding.
• Potential additional cost and schedule impact to
  late 2002 LRD

• ICESat is unfunded beyond 5 / 31 / 02
• Cost / schedule impact of SN001 Laser and other
  anomalies

• CURRENT STATUS
• Schedule and cost requirements ready to be
  presented to HQ / Code Y in mid-March.
• Code Y PMC rescheduled for May 3.
• Working with Code Y to determine plan for
  providing additional mission funding. Plan may
  require substantial FY02 carryover and FY03
  emergency operating plan submittal.

ICESat SIGNIFICANT PROGRESS
ICESat Project STATUS AS OF 3/31/02

• THE GLAS INSTRUMENT IS FULLY INTEGRATED.
• GLAS HAS SUCCESSFULLY COMPLETED ACOUSTICS
• GLAS VIBRATION TESTING IS UNDERWAY TWO AXES
  SUCCESSFULLY COMPLETED
• INITIATED A RISK MITIGATION EFFORT TO DEVELOP
  CORRECTIVE OPTICS DEVICE FOR USE IF THE GLAS
  BORESITE PERFORMANCE PROVES TO BE UNACCEPTABLE
• INSTALLATION OF HEATERS ON UPPER DECK OF THE
  SPACECRAFT IS COMPLETE. LIMITED FUNCTIONAL
  TESTING IS UNDERWAY FULL FUNCTIONAL TESTING WILL
  TAKE PLACE IMMEDIATELY BEFORE GLAS DELIVERS.
• CONDUCTED A EEE PARTS AUDIT ON THE SPACECRAFT
  BALL HAS HANDLED RESIDUAL PARTS PROBLEMS VERY

END OF MISSION PLAN DEVELOPMENT COMPLETED
ICESat Project STATUS AS OF 2/28/02
Final Estimate Final Orbital Debris
Generation report was approved by Headquarters on
4 / 9 / 01. The total mission package included
ICESat, CATSAT, DPAF, and launch vehicle. Both
ICESat and CATSAT meet the 8m2 guideline by
significant margins. ICESat is 3.9m2 and CATSAT
0.9m2. ICESat will reenter in 15 years, which is
well under the 25 year guideline. Disposal
Option Assessment Controlled Reentry Not
practical -- 240kg additional fuel and 6 months
delay Safe Orbit Not feasible -- same as
re-entry Shuttle Recovery ICESat polar orbit
not accessible to the shuttle also spacecraft
design not manned-flight rated Expect no changes
when CHIPSAT data becomes available
