Dear lady-senator Latharion,
I did not intent my previous message as a formal agreement. I wished to give you an alternative besides costly research. However, as you seem to be interested, allow me to answer your questions.
We would, of course, not require payment up front; though we would appreciate a statement of intent. As I already said, the exact details of payment of the licence are usually handled with the associated terraformation project.
In our current projections, we could start the research in

81, wich mean it would be finished in

90. We could start the terraformation project as early as

91. But due to previous treaties our supply of terraformation modules is limited, and we would only reach full terraformation potential around

95.
Yours sincerely,
Lady Nehket Aeka
