Procedure: Learn the responsibilities of the other
teams.
Work with the Camera Team to determine the scale relationship
of the camera. Create a scale map of a "sample rock field"
constructed by the Camera Team. We used the video tape they gave
us. We created a scale map of the mission site as if the site
were viewed from above. We included the placement of all objects
that would affect the rover's movement or could be the mission
objective (which rock to visit).
We made a full-scale model of the "landing site"
using our scale map. We enlisted the help of the Navigation and
Camera Teams.
We worked with the Navigation Team to plot the rover's expected
path during the mission. We plotted rover actual positions during
the mission. We worked with the Navigation Team to devise new
expected paths as needed.
Hints: We kept it simple. We made our map as large
as possible.
We used circular graph paper for our maps then applied what we
learned to the Lander Site map.
