Orbiter and lander integration and test activities are proceeding on schedule with no significant problems. The flight Mars Descent Imager (MARDI) instrument was installed on the lander on Feb 9 and the camera achieved excellent performance in functional testing. Tests at Lockheed Martin indicate that MARDI is capable of imaging the surface after landing at millimeter level resolution. In addition, the MARDI field of view provides images of the surface which extend approximately 4 meters from the surface location of the lander. The MARDI installation and checkout completes the lander payload integration activities until the flight TEGA (Thermal and Evolved Gas Analyzer) is installed in June 1998. The Mars Color Imager (MARCI) will be integrated on the orbiter on Feb 18 and acoustic testing of the orbiter spacecraft begins on Feb 19.
