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.
To reach it, you need the hovercraft in the top of the mill. Pull the rope inside the hay loft that unlocks the gears, then go outside and climb on the windmill to turn the blades counter-clockwise. This will open the mill roof dome. Inside, add manure to the hovercraft and it will travel to the swamp.
To fix the Excalibur, you need a replacement green fuel rod. If you can enter Mordred's underground lab, you can reach the back of the dungeon to get to the robot invader being held there.

The hovercraft in the mill will let you reach the alien saucer Excalibur in the mud swamp. You will have to get a new green fuel cell for it, and there is one in the captive robot in the dungeon.

The saucer Exclibur is crashed in the mud swamp past the Mill. Get the hovercraft and go out to it. It needs a new green fuel rod, and luckily there is one inside the captured robot in the dungeon. You need the coordinates for the nearby Pewter Moon, which are X-56 Y-52. Once the new fuel rod is in, you can change the dials to launch.

Use the hovercraft to reach the Exaclibur in the mud swamp to the right of the Mill. You will need a new green fuel rod and the coordinates to travel into space.
