WEEKLY HIGHLIGHTS FOR WEEK ENDING 7 MARCH 2003:
SUCCESSFULLY COMPLETED SPIN BALANCE WITH FULL MAIN TANK
The space vehicle test team has successfully completed the 90+% full main tank spins. Spin rates of up to 40 RPM were achieved. The plan is to
complete spin balance operations by the end of the week thereby completing the associated NASA critical milestone. The expectation is that the
PDU will be available for installation on the vehicle by early next week with space vehicle software testing to follow.
