What does NASA mean in a rebus puzzle?

Answer 1

In a rebus puzzle, NASA can be represented by using images or symbols to convey the sounds of the letters. For example, you might use a picture of a "na" (like a person shaking their head for "no") followed by a picture of a "saw" to represent "sa" and an image of an astronaut or a rocket to represent "A." The combination of these elements visually conveys the acronym NASA.
