Mars Climate Orbiter:

Orbiter integration and test activities continue to proceed on schedule. Mission System Testing of the launch/initialization phase was repeated very successfully on August 26 with a fault protection case causing a side swap inserted. The Mapping phase test conducted on August 22 was halted midway through the test due to a computer reset. This fault has now been duplicated in the Spacecraft Test Lab for the first time which provides promise that the root cause of this and previous resets will be determined. The orbiter is on schedule for shipment to Kennedy Space Center (KSC) on September 10. The only remaining work on the orbiter prior to ship is the dry spin balance in vacuum scheduled for September 5.

Mars Polar Lander:

The lander is being assembled into the cruise configuration and is on schedule to begin cruise thermal vacuum testing on September 2. The backshell and cruise stage are installed and the spacecraft is scheduled to move to the thermal vacuum chamber on August 29. The lander pre-ship review is planned for September 15. Shipment to KSC is planned for October 12.
