(i) Define the four events described above. Give each a name(e.g. Event 1, Event 2), and list the events in the order in which they occur as seen from the Earth-Moon frame. (ii) Draw a labelled diagram showing the two frames of reference at the event where the radio signal arrives at the spacecraft. These should be in standard configuration; a two-dimensional representation (x and y axes only) is sufficient - you do not need to include a z-axis. Your diagram can be based on Figure 1 and should show thecoordinate axes of both frames. You should also label the timecoordinate of this event as seen in both frames, (iii) List (in light-seconds and seconds) the position and time (x and t)coordinates of each of the four events as seen from the Earth-Moon system.
