Rocket in a vacuum by magnetman33
My attempt at a simulation of a rocket engine in space. Requires waiting for best results. Also try it without the wall and pump around it to see the difference.

this is a really good attempt, it's just a shame about tpt physics :( it acts more like it's in a vacuum when it's at the regular ambient pressure because it's going slower and has more time to expand. IRL it should be underexpanded in a vacuum (keep expanding a LOT after it's left the nozzle) and overexpanded at sea level (the gas doesn't make contact with 100% of the nozzle wall because the air pressure squeezes it in). it's still cool how the flame becomes translucent. +1
