Now your spaceship is passing by the Dark Side of the Moon. 

Now your spaceship is passing by the Dark Side of the Moon. It's a glorious view! To ensure things are working properly Commander Amelia Brand and Pilot Rheya Cooper ask you to run the Chandy-Lamport snapshot algorithm on the ongoing communications between your spacecraft, and the manned Earth station, and manned Moon station. But due to a crash at the different stations, the algorithm only outputs the following timeline. In the figure, a, b, c, ... are regular application messages. You can use S(a) to denote the send event of a and R(a) to denote its receipt event. Markers shown as dotted lines. Can you help the intern find the snapshot recorded by this run? Don't forget to include both process states and channel states. For process states, you can use the name of the latest event at that process (For initial state, just say "Initial state". Note that Markers don't count as events). Quick, it's up to you to manually calculate the snapshot! f NHX Earth Moon a C g Marker Message Regular Message c
