Frankly, the name Constellation may be french originally, but if the next kind of spacacrafts will be named that way, I have a little problem.
First, it reminds more of astrology than of astronomy.
Second, the Shuttles were named after famous ships; the next spacecraft won't be at all like the Shuttles.
Third: the name is too long!!

Constellation One, this is Houston, over.....

Every previous spacraft had 3 syllables: Mercury, Gemini, Apollo, Columbia, Challenger, Atlantis, Endeavour (ok, Discovery also had 4 syllables (though "very" can be shortened to "vry" but also you don't add the flight number in Shuttle flights).

Why not be as imaginative as during the early NASA years?
