The most frequent questions I get about LCROSS go something like, “You’ve been flying for ‘x’ days…aren’t you at the moon already?”, “Why does it take so long to reach the moon?”, or “What are you doing with all the extra time between now and impact?” Admittedly, the answers are hard to communicate, because the LCROSS mission profile isn’t as straightforward as one might guess.

Interesting, but somewhat crunchy ...
