How do you get the flying saucer out of the mud on Astro Knights Island?

While Mordred's hovercraft runs on manure, the saucer is advanced technology. It has a green fuel rod that has been broken. You need to get a replacement fuel rod.
For the procedure, see the related question.
Setting the coordinates, you will find that none of the planets is in range. Go to the moon mentioned on Mordred's missing journal page, at X-56 Y-52.


When you build a new spaceship, there is a single-click launch button.
