Because weight is expensive. The more weight you have to lift, the more fuel your rocket needs, and remember that a rocket also needs more fuel to lift the additional fuel, so even adding one pound to the weigh to a space ship can require several tens or hundreds of pounds of fuel to lift it. Water is already present in the space capsule, the astronauts are largely made of it and can bring what more they need; and they will also be recycling it, if they are to be in space for long enough. Why waste the fuel to bring more heavy water to space if it's not necessary?
