3. Suppose a 128-kbps point-to-point link is setup between the Earth and a rover on Mars. The distance from the Earth to Mars (when they are closest together) is approximately 55 Gm, and data travels over the link at the speed of light-_3x 108 m/s. (a) Calculate the minimum RTT for the link. (b) Calculate the "data-in-flight" for the link. (c) A camera on the rover takes pictures of its surroundings and sends these to Earth. How quickly after a picture is taken can it reach Earth Mission Control? Assume that each image size is 5 Mb. (10 points)
