You've recently been hired by NASA/JPL to work on the Mars 2020 mission. Part of your new job is to examine the telecommunications parameters of the new rover, which will land on the martian surface and collect scienti c data and pictures for transmission back to Earth.

The rover has two on-board radios, one that can transmit and receive at a maximum rate of 32 Kbps directly to Earth or a 2 Mbps radio that can communicate with the Mars Reconnaissance Orbiter.

The Mars Reconnaissance Orbiter (MRO), which orbits Mars at an altitude of 300 km from the martian surface, can transmit and receive data back to Earth at a rate of 6 Mbps and can be used as a relay to communicate between Earth and the rover.

Assuming the distance from Earth to the surface of Mars where the rover is located is at its greatest (401,000,000 km),
data travels over the communication link at the speed of light (3.0 108 m/s), and they use a maximum 512 byte frame size with a 508 byte maximum variable size payload, and constant 4 byte header, answer the following:

Suppose NASA takes several pictures of the martian surface and wants to transmit them back to Earth. The total size of the pictures is 50 MB.

Exactly how many bytes need to be transferred taking in to account framing? How many frames need to be transferred and what are their sizes (summarize)?

How long would it take the rover to transmit the pictures directly back to Earth?

How long would it take to transmit the pictures back to Earth using MRO as a relay? Assume 5 ms of queuing time per frame relayed.
