Topic: space shuttle

In the beginning era, space shuttles are seen painted  (from outside ). What's the reason?


Re: space shuttle

You are probably referring to ‘external tank’ of the space shuttle. External tank carries the propellant used to run the main engines of the luanching system of space shuttle.

The external tank is not reused and is discarded within first few minutes of launching. Under such conditions, painting of the external tank does not result in any specific advantage. Hence, painting of the external tank of the space shuttle was discontinued after first few launches. In fact, this reduced the weight of the system marginally (by about 300 kgs).
