The difference between True North and the direction that a magnetic compass points for a given location. Example: the magnetic declination for Seattle, Washington per the NOAA is 16° 55' east (as of 04/2010). This means that magnetic north is predicted at 16° 55'east of True North at that time.

In a word, no. A conventional magnetic compass only indicates the *Earth's* magnetic field. The influence of any extraterrestrial magnetic fields falls off according to the inverse-square law, that is, the force is diminished by the square of the distance from the source. What this means is that any fields present from other objects are very small compared to the Earth's own field. You can demonstrate this by influencing a compass with a small bar magnet. Once you leave the vicinity of Earth, the usefulness of a magnetic compass disappears almost immediately. Of present technology, Inertial Navigation is the most suited for space travel. By using accelerometers and gyroscopes to measure acceleration along each axis, and rotation around each axis, you can keep track of distance and direction traveled. That's how spacecraft got to the moon, planets and beyond the solar system. Addition: A sextant will always be a handy navigational tool. If interstellar travel ever becomes a reality a real time pulsar triangulator will be a necessity. Every pulsar has a unique rotational frequency. By triangulating apparent angles between the pulsars a spacecrafts position in space can be known.
They live in California and Mexico, near ecological lifezones as well as deserts and mountains.
Adjust the declination on your compass so the orienting arrow points to 10 degrees east. Dial zero degrees on your compass. With the direction-of-travel arrow pointed directly away from you, turn your body & compass in one motion until the redmagneticneedle overlays the orienting arrow.

The compass direction of travel.
A compass is an awesome travel symbol. Can be as simple or as elaborate as you like.
They have their territory that they travel in with their pack.
this compass appears as a pocket watch and is suitable for general travel that requires limited accuracy

In my opinion I think the magnetic compass is more important because It made worldwide travel easier and encouraged more exploration.
