How would/do we navigate on another planet or the moon without GPS or magnetism.?

Polaris may not be due north on a planet with a different tilt to its axis, but you would use whatever was due north as a pole star instead

Time?  No.  Space?  Hell no.\n\nUnfortunately, we will never be able to do either of the two.  The energy levels in our solar system are what hold our molecules and atoms together.  Stray too far and you will find yourself entering a part of the Universe that has a different charge balance, the electrons will begin flying off, and you will start falling to pieces.\n\nTime travel is a concept that everyone can understand so it persists.  Any changes that have happened to the matter have already taken place, there's no going back.  Just like you can't unburn a match, you can't turn back time.

Maybe a geosynchronously orbiting satellite. Those are satellites that rotate with the Earth so it appears that they don't move from our perspective.\n\nObviously, anything else (including stars) would move as the night progressed.\n\nHope that helps.

a variety of different ways. there are vhf transmitters all over the world for navigation. satellite navigation is becoming more popular. all aircraft in the u.s. are also equipped with a plain old compass also.

Solar Sails.\n\nA spacecraft would deploy a huge sail to capture the solar 'wind', the constant stream of solar particles. A rather slow but economical method to move beyond Earth....

Dependant upon the altitude of the craft together with it's power, we can choose the speed in which we can cecum navigate the planet.\nThe craft will take off and land in the same way, we can travel around the planet in any direction and choose the speed, but if we were to leave the earths atmosphere, we then control our exit speed and aimed in the direction we require, we would then be able to use the speed of exit. to travel great distances in less time and with less fuel.\nIf we stay within the earths confine, but at extreme altitude, we can then travel at greater speeds.\nGo to the NASA site and look up scram jets.

Our moon is locked in what is known as a geo-synchronous orbit. For millions of years the angular momentum has stablized the moon to provide very little loss of energy between earth and moon. This does not account for the influences that the moon has upon our oceans though. (Tides) Our solar system has "moved about" for many millions of years to allow for efficient energy transfers between baryonic masses.  This is not unlike a person who sit's in a chair and move's about to become more comfortable.  Peace

Go to www.Bored.com there is a lot of fun stuff there.One is a you can put in addresses and it will tell you where you would pop out on the other side of the earth.

Umm, your own source disputes your claim of no magnets:\n\nForm Wikipedia:\n\nObservations of the magnetic fields on Mars by the Mars Global Surveyor spacecraft have revealed that parts of the planet's crust have been magnetized. This magnetization has been compared to alternating bands found on the ocean floors of Earth. One theory, published in 1999 and reexamined in October 2005 with the help of the Mars Global Surveyor, is that these bands are evidence of the past operation of plate tectonics on Mars.[14]\n\nSo yes, a compass would work but not necessarily point to the north.

None.  We have had a fly-by, but no orbiters.  Messenger will eventually be there, but it is rather hard to orbit mercury.  You launch a probe to it, and you need to be pretty craft to be able to stop it at mercury since it will have a tendancy to be accellerated into the sun.

WHEN YOU ARE ON EARTH U CANT FIND ANY POINT. YEAH I THING IS POSSIBLE. U CAN PURCHASE A GLOBE AND ROTATE IT. U WILL FIND ROTATION THERE.!

It depends on what you are trying to do.\n\nIf you are trying to find intersellar radio signals in the nighttime sky (SETI@Home), computers are much more efficient. If you are trying to navigate a vehicle across rocky terrain (DARPA Grand Challenge) apparently humans still beat computers at that pretty handily.\n\nThat doesn't mean that computers won't one day be better at off-road navigation than people, but such is not the case at today's state of the art.
