The bubble was, of course, oriented so that its pole pointed to the sun.
Mars' north pole currently points at Cygnus and not Ursa Minor.
At the present time, Triton's rotational axis is about 40 from Neptune's orbital plane, and hence at some point during Neptune's year each pole points fairly close to the Sun, almost like the poles of Uranus.
All poles are pointing toward (or all away from) the center.
It takes approximately 28,500 years for the full circle to be traced, and over this time, the pole gradually points to different stars in the sky, or to none.
In the 2070s the south pole will be pointing to the Sun once again.
The poles of its atoms all point the same way.
Since the system relies on the reflection of sound waves, it may not detect some items that are not flat or large enough to reflect sound, for example a narrow pole or a longitudinal object pointed directly at the vehicle or near an object.
Very important that the pole is pointing top and bottom.
First it would show a picture of the Eyes of Bright over the east pole with a dragon tooth pointing the way to Bright's Heaven.
