WEEKLY HIGHLIGHTS FOR WEEK ENDING 24 JANUARY 2003:

PREPARATIONS UNDERWAY FOR SPACE VEHICLE SPIN BALANCE
The space vehicle test team is in the process of preparing the vehicle for the upcoming spin balance test. Mass simulators are being installed on the vehicle to substitute for some of the not yet installed flight hardware. A list of differences from the flight configuration (i.e. not yet installed flight hardware or GSE) will be used together with spin balance test results to balance the vehicle for flight. Action items from the recent Test Readiness Review are in-work.
