Great idea
Thank you.
Here's another suggestion to build on the psychic drive idea: Let's say that the psychic dimensional drive can only do it's magic (move between galaxies) once it's sufficiently beyond of Earth's gravitational field (something about the field inhibits the dimensional shift effect), so that all the alien has to do is get his ship up to space shuttle altitude, or something along those lines, and he's home free.
That solves the problem of galactic travel while still allowing you to give your alien an "earthly" challenge which kids may be able to relate to (because it's essentially shuttle technology, or perhaps X-Plane technology). Maybe you could look at some of the ways the X-Prize challengers tried to solve the problem, and use one of those designs. That should give your young readers all the realism they can stand while allowing you to slip around all the real-world phisics which prevent galactic travel.
