Jason: I will grow and grow and be an adult. But will you be really old when I am as old as you are now? How long does it take to get to Saturn? When I grow up I am going to be a scientist who makes a rocket that can get to Saturn in one minute. I am going to need a lot of wire, a huge engine, and infinity gasoline.
Sydney: Why does it take us so long to get to Mars? How can we get astronauts there when it's so far away and so hard to find?
[note: Jason and Sydney are in different rooms, so it is entirely coincidental if they ask me about the same or a similar topic.]
