Earth, Can You Hear Me Now?

How long did you say? Class groups plot the distances between Earth and Mars and determine the trigonometric function that models the data. Using a calculator, they graph the function to determine when the distance and communication times are the shortest, the optimum time to land a spacecraft on the Martian surface.
