@Thiel: space is near absolute zero so cooling is not an issue that much.
WOW... I have never seen anyone fail high school physics this badly.
It is very difficult to get rid of heat in space, as it can only radiate, it cannot conduct or convect. Even though space is very cold, something building up heat will retain it for a very long time, unless it is particularly good at radiating heat.
This is why the ISS has massive banks of heat sinks.
stupid boy.
Also, APDAF, do you know how small RCS's are? they fit in the nose cone of the shuttle. You cant see them there. Why would you see them at this scale.
