Mars Climate Orbiter:

Pyro Initiation Unit (PIU) ATLO Test Unit (ATU) troubleshooting was successfully completed. The previously observed failure was duplicated on the vehicle and the data captured. Belief is that the ATU contains a defective part. The ATU was removed and returned to Denver for analysis and the reworked flight PIU was reinstalled on the orbiter. The reworked flight PIU functions and interfaces were retested and reverified successfully on the orbiter.

Mars Polar Lander:

The Attitude Control System (ACS) phasing test was partially completed with several issues regarding the star camera to be resolved. The launch/init mission system test was conducted successfully. The star camera issues discovered were determined to be caused by incorrect paramaters in the lander database. The star camera portion of the ACS phasing will be repeated next week.
