I wouldn't call that a safe assumption by any stretch of the imagination. With nanotechnology just getting into full swing, I think we are going to start seeing major advances in the field of materials science. If you consider how far we got with the "lets put this metal in a fire and see what happens to it" approach to metallurgy, then it's far too early to discount a field that we are still learning to fully understand.
They are always finding/creating new alloys, I wouldn't mind seeing something like a polymetamorphic titanium alloy. (Rise of the robots movie!)
You see thats where you are wrong. A moon is a miniature planet caught in the orbit of a bigger planet. Similar to Earth cyrcling round the sun. It can have its own atmosphere and its own life. Just because it cyrcles a planet and not directly the sun doesnt mean it has no atmospheric conditions (or water in this case). Triton os one of the closest things, discovered so far, to Earth in our solar system along with Mars and Venus.
But don't let that confuse you into thinking moons are tiny planets. To say all moons are "miniature planets" due to 1 or 2 planets, is the same as saying all people are retarded because I met 2 guys on the train who were retarded.
Thats basically my point. Since moons and planets are generaly built the same way. We have only one identifier. And thats that moons cyrcle round plnets and not the sun. The rest is about the same.
True. But the asteroid has no core. Taking Earths moon for instance. It has its own core.
