Something along those lines sounds neat, but it would be a pain to write Constellation Actual, Constellation 2 or whatever. Seems like whatever name would actually be used would be short and sweet for less cumbersome communication. 

I do like Discovery, also did suggest Mercury which was the series of missions that NASA started trying to create their first rockets... I think if my memory of the history of space exploration isn't wrong. Anyway naming something after the first rockets feels like it fits as well.

Looking back, I think now that I'm relatively awake, I kind like either Apollo or Mercury with a leaning towards Apollo.
