COMPUTER NETWORK

9. Consider a rover placed on the surface of Mars. Normally, Mars is about 140 million miles away from Earth. Suppose some command to maneuver the rover is sent from Earth. In free space the signal propagation speed is the same as that of light (0.3*106 KM/second). How long will it take for the signal to propagate from the surface of Earth to the surface of Mars?

    2. Mars is currently 35.8 million miles away from Earth. How long would it take to send a radio signal to the Curiosity rover on Mars and receive an answer from the rover, assuming that the rover answers instantly? In other words, what is the round trip travel time for an electromagnetic wave to Mars right now? Recall that c = 3.00 x 108 m/s. Also, 1 mile = 1.61 km. Answer in minutes.

    f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...
