If you are refering to rain like you see it here on Earth then no, because in space there is no one way for the water to fall down to like on Earth. Here, gravity pulls down the water molecules and they fall down to the ground, then they are heated up by the sun and the water turns in to vapor in the atmosphere. There a lot of the molecules bundle up together and the heavier bundles are pulled by gravity to become raindrops. In outer space there is no liquid water and no strong gravity pulling on the water molecules so they are just floating, and there is no rain in outer space.
