LCROSS info is here if needed. Any interesting mission though one has to wonder if the project may have started with something along the lines of “Hey, wouldn’t it be cool to smash something really big into the moon?!?”
In any case, the shirt will not be your standard printfection t-shirt, so send in those guesses, kids!
OK, I’ll bite. Four-aquare?
Ding, ding, ding!!!! And we have a winner! Holy cow, I was afraid people were going to get made that I had made such a simple puzzle, but I have been deluged with requests for hints. In any case, email me a shirt size and a postal address, and congratulations!
