Subcue testing event. Workers in the Spacecraft Assembly and 
Encapsulation Facility-2 (SAEF-2) lift the Mars Polar Lander to move it to a 
spin table for testing. The lander, which will be launched on Jan. 3, 1999, is 
a solar-powered spacecraft designed to touch down on the Martian surface near 
the northern-most boundary of the south pole in order to study the water cycle 
there. The lander also will help scientists learn more about climate change 
and current resources on Mars, studying such things as frost, dust, water 
vapor and condensates in the Martian atmosphere.
