Clustering
STS stands for what regarding the space shuttle?
Space Transportation System
What are the two types of rocket fuel commonly used today?
solids and liquids
Why are solid rockets more dangerous then liquid rockets?

Werner Von Braun started his rocket career in which country?
Germany
Why did NASA stop painting the shuttle’s external fuel tank after STS-1?
