Watched the IRON SKY trailer a while ago and it showed a scene where some Nazis where firing a rocket launcher on the Moon's surface which of course has no atmosphere…

So… if in reality one re-enacted this event.

a) Would the fired rocket (depending on the nature of the propulsion system) leave a trail of smoke?

b) If so, what would happen to the smoke? (obviously it cannot dissipate - no atmosphere)

c) How long would it remain visible after the event?

d) Would the person firing the rocket launcher be pushed in the opposite direction?

a: if it burns, probably
b: guess it would slowly sink down
c: until the next scene
d: certainly

You do realize however, that the film is a parody...?

Oh absolutely… but It made me wonder, that's all.

On the same note: I remember watching the Lunar Lander ascent module blasting off. No smoke as far as I remember. I wonder what type of rockets they used?

Found this video - no smoke.

Lunar module blast off and leaves the Moon (Apollo 17)

I read that most of the shuttle smoke comes from the sprayed water on the launch pad

Sure enough but not when its off the pad and in the air.

I never saw any engine in space produce smoke

[horatio]

I have.

The flip side is, the Iron Sky trailer looks damn fun! And I think we can discount scientific accuracy as being a key component!

The only people who won't enjoy this film are pro-republicans XD
