Mars Climate Orbiter:
Orbiter launch processing activities are proceeding on schedule in the
Spacecraft Assembly and Encapsulation Facility (SAEF-2) at Kennedy Space
Center (KSC) with launch 41 days away. However, several days
of schedule margin were consumed due to a problem with flight software
build 8.1 which prevented the "B" side of the spacecraft from booting
during testing. The cause of the problem was determined and the fix
will be incorporated into build 8.2 scheduled for delivery on November 2.
Software build 8.0.1 was used to continue electrical testing of the
orbiter while waiting for 8.2. The down time caused by this software
issue was used to accomplish mechanical closeout tasks required to
configure the orbiter properly for launch and to troubleshoot various
anomalies which occurred in previous testing.
The reworked flight Pyro Initiation Unit was reinstalled on the orbiter
and all functions and interfaces will retested and reverified next
week. This completes the glass body diode rework effort for both the
orbiter and lander vehicles.
Mars Polar Lander:
Lander launch processing activities are proceeding on schedule in the
SAEF-2 facility at KSC with launch 65 days away. This was a major week
of testing activity on the lander with the following tests completed
very successfully: rocket engine module functional test; entry,
descent, and landing "plugs out" test; mission profile tests on side
"A" and side "B" of the lander using new flight software build 8.0; and
attitude control subsystem phasing verification test. In addition, the
backshell and harness assembly and cruise stage were installed on the
lander vehicle.
