Calculating Curiosity's Position

 

  I used a HIRISE image of Curiosity on Mars to obtain a better estimate of her position from two intersecting lines. To choose the lines I used a ruler to pick two points on objects on opposite sides of Curiosity's position so that the line passed through it and marked them red in Paint. The coordinates of these points were found on Google Mars using the placemark tool. The solution for the position, X, involves finding the intersection of the two lines which is,
