And last of all.... make sure that your puppy has eaten his dinner several hours before bedtime...a good rule is 4 hours prior. This way he will have plenty of time to do his business outside in the yard before going into his crate for the night.
The CIA (Central Intelligence Agency) mostly operates outside the United States to gather intelligence via a network of spies whereas the FBI (Federal Bureau of Investigation) predominantly operates within the U.S. to both gather intelligence as well as tackle federal crimes.
Here i am guessing you wrote NSA, cause your question actually says NASA. Probably a typo. NSA - NSA is basically a intelligence gathering agency. They do any and all kinds of surveillance. The original goal was to monitor foreign nationals inside US or outside US who might be a person of interest. Recently it came out that NSA also conducting surveillance over US citizen inside US.
