What does "S" stand for in NASA?

Here on the northern end of the Mississippi river there is another group called nasa. North American squirrel association. They arrange fishing and hunting for the handicapped. Thank you folks!!

Mel, I voted your comment up. But please don't use all caps. It can come across as shouting, and is harder to read.

MY DAD USEDTO WORK FOR NASA AS AS A TECHNI IAN. HE COULD NEVER TELL US WHAT THEY WERE DOING. EVERYTHING WAS SECRET.. I DONT KNOW HOW MANY ROCKETS. HE WORKED ON IN THE 60SAND 70S.
