Just seen Avengers Assemble

How did the rocket propel itself without oxygen?

Because Solid Propellants have their own oxidizer within. This ensures a proper fuel to oxidizer ratio. So they do not rely on outside conditions to burn.

Why did Ironman "fall" in space? There was no indication of gravity or suction by the portal yet he fell through it like a stone.

Gravity from earth being translated through the portal maybe?

Understood, as a lot of the trip could be extremely high altitude. But, as far as I've read, they still rely on atmospheric oxygen for the final combustion.

Did you watch the behavior of the aliens near the portal? Seemingly no effect (though one could argue they were barely affected on earth as it is). If anything the differences in pressures would have the opposite effect.

Nope, solid fuel rockets do not need any outside conditions to burn. When both the fuel and the oxidizer are in the "Solid Fuel", all you need is heat to kick off the reaction.

It's the same thing as gunpowder. You can fire a gun underwater, or even in space, because the fuel and it's oxidizer are both contained within the gunpowder.

This is why SPIDER-MAN didn’t make it into the final cut of Avengers..
