Introduce a virtual starting node in the graph to account for different launch epochs #54

Closed darioizzo closed 10 years ago

darioizzo commented 10 years ago

In mission 1 (for example) we have an Earth launch as a first trajectory leg. This involves the optimization of the launch epoch. The starting node of the graph is, though, always visualized at the same epoch, even if the launch conditions (i.e. epoch) were entirely different.

I suggest the introduction of a virtual empty node which will not be visualized and will be the root. Each successive node can then be placed on the epoch timeline correctly.

This would also mean that upon optimization of the first leg in mission1, two nodes will be added to the graph, i.e. Earth and (say) Venus .......
