1998 MARS SURVEYOR PROJECT
STATUS REPORT
December 8, 1998
John McNamee
Mars Surveyor 98 Project Manager
Mars Climate Orbiter:
Launch -2 Days
The NASA Launch Flight Readiness Review was conducted.
A contingency plan review uncovered a plausible failure mode in the
fault protection software involving the Charge Control Unit (CCU) where
a part failure in the CCU could result in catastrophic failure of the
battery. A software patch (involving hard coded parameters only - no
logic change) has been identified to resolve the problem and the team
is preparing the test program required to verify the fix and to insure
no unexpected side effects result. The project has recommended to NASA
and Boeing that the orbiter launch be slipped 24 - 48 hours. The
Project will insure that a rigorous test program is executed and that
personnel are rested prior to initiation of the launch countdown.
Mars Polar Lander:
Launch - 25 Days
Hydrazine was loaded on the lander successfully.
