Right now when going outside the airlock the player inherits the ship's velocity but for some reason he gets a slower speed, possible causes: hitting the ship at high speed or some residual air resistance slowing you down. You got me curios, I will take another look at it.
Please do. When trying to go back into the ship from EVA, every light touch, as the ship was moving would prevent me from entering. Even when I was almost in the airlock, if my feet just gently touched the ground, even with mag lock on, I went woosh. I even once got so much speed from a very very minor touch trying to see if I can mag lock onto the top of the ship, that within seconds I was kilometres away.
