    Hi!
    I hope I'm not lowering the level of these forums by asking these questions.

    Basically I'm a Game developer.
    I'm doing 3d art for a space related Game.
    My current task is to make explosion effects.
    I want to atleast try to be accurate.

    Would anybody have any tips on the dynamics of explosions in space in this context. Any kind of media of a flame/explosion/fire in a pseudo vacuum would be helpful (pseudo as in partial oxygen environment).

    Even media of the space shuttles engines active in space would be helpful.

    Explosions in space are not visibly lasting. Even a nuclear explosion would be akin to a camera flash. The 'blast' of a non-nuclear explosion or the radiation of a nuclear explosion is more devastating than on Earth but without the sensory evidence of sight and sound. A controlled burn from a rocket would be visible but an 'explosion' would almost instant in visibility then gone even with oxygen available' as there is nothing (like air pressure, a density of molecules, etc.) to contain the blast. Blasts both nuclear and non-nuclear would be devastating over a far greater distance.

    Unlike video games, war in space wouldn't need a video monitor or sound system.

    Thanks for the reply.

    Thats what I generally thought.

    Thing is people expect some kind of signifier that they have hit the other guy successfully.
    Kind of dull if nothing substantial happens when you make a direct hit.
    I downloaded some videos of candle flames in microgravity was thinking of doing something along those lines, spherical flames and such.

    A video of the rocket engines in space would still be useful though as I predict I will have to do engine effects eventually.

    Well, I think part of what he's suggesting is that air pressure pushing back on an explosion is part of what makes it have a lasting flame. In space, nothing pushes back. Everything just flies off toward infinity.

    There is nothing to stop radiation and the effects are potent. Something like 25 or so times greater for a modest tactical nuke than in the atmosphere at sea level pressure. With the dumb nukes during the 70's this wasn't such an issue but with more precise targeting available today a country with nukes and space technology can take out more or less everything orbiting the earth. This is one of the reasons the U.S. was concerned about such technology tested by China last month.
