Write a program that will solve Lambert's problem using the iteration method. Use the method outlined in the supplied class notes. The input should be the initial position vector r_1 and the final position vector r_2, as well as a desired transfer time. The output should be the required initial velocity vector r_1. To test the algorithm, use the position vectors r_1 = (7308.64, 319.72, -1269.75) km r_2 = (290.12, 6610.86, 3529.31) km relative to the Earth and a transfer time of Delta t = 1600 s
