NASA is the government agency responsible for space science and exploration. The round NASA logo known as the "Meatball" has a blue circle that represents a planet, the stars represent space, the red chevron is a wing, and then the orbiting spacecraft going around the wing. This Grey 100% terry towel features a large "Meatball" NASA logo in the middle. This towel measures 30" X 60". This is a great towel and is perfect for the pool, beach or showering at home. Makes a great gift too.
