Partner Cosmic Hot Interstellar Plasma
Spectrometer (CHIPSat) Mission Objectives
1. Produce high accuracy and calibrated
profiles of ice-sheet surface elevations over
Greenland and Antarctica. 2.
Produce calibrated profiles of global land and
ocean surface elevations. 3. Produce
calibrated vertical profiles of global cloud
heights and vertical distributions of cloud
and aerosol properties for the first
time. 4. Map high accuracy ice-surface
elevation changes over Greenland and Antarctica
for the first time. 5.
Characterize the seasonal variability of
ice-sheet surface elevations over the mission
lifetime. Website http//icesat.gsfc.nasa.gov/

END OF MISSION PLAN DEVELOPMENT COMPLETED
ICESat Project STATUS AS OF 10/31/02
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
