MPL MARDI Release No. MARDI99-02, 2 December 1999
The "video" is presented at twice the speed of expected descent. Three types of images are acquired by MARDI, and these are shown as they are acquired in the upper right: 4 small images capture the heatshield jettison in a 2 second period, followed by as many as 16 full-frame pictures taken every 5.3 seconds before the descent engined begin firing, and as many as 10 pictures taken every 4 seconds during terminal descent.
The images used to make this simulated descent movie are derived from Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) images of the polar landing zone obtained over the past few months. The images were generated from topographic information derived from MOC images of the frost-covered surface. The simulation of landing is based upon the predicted behavior of the Mars Polar Lander spacecraft during its final descent on December 3, 1999.
