For example, how much can be said about the the entire south polar region of Mars based upon the results to be provided by the Mars Polar Lander? Read More...

Science with MARDI
The way a surface looks depends on the strength of the materials, the strength of the processes that are eroding it, and how long these processes have had to work. Descent images from MARDI will bridge the gap between what can be seen and learned about the polar surface from orbiter cameras--such as Mars Global Surveyor's MOC--and the lander cameras--such as Mars Polar Lander's SSI. Pictures from Antarctica, as shown on the left, help illustrate descent imaging science. Read More, and see the Antarctica descent pictures...
