[meteorite-list] NASA and "cute" mission dates

[Darren Garrison]

So, does NASA make lots of effort to give their exploration missions "cute" dates?  I'm thinking
about the February 14th date of entering orbit around Eros, and the July 4th date for the fireworks
display of "Deep Impact".  Are dates like this really by coincidence the best timing, or do they
choose less-than-perfect times to get special dates?
