how many years does it take to get to mars?
343415
With current speeds it takes about six months to reach it.

By that time we'll be off the planet...hopefully on mars...its possible that we could live on mars the only problem is that it may take about 50 or more years.

I think your facts of science need to be updated.\n\nMars orbit is 1.5 AU (about 145 million miles)  from the Sun. \n\nThe Earth is 93 million miles away from the Sun.  At its closest, Mars is about 50 million miles away, and we have sent many probes to Mars without the need for "infinit (sic) energy"\n\nA manned Mars mission is well within human ability.

We cannot leave our solar system until we figure out how to travel at much higher speeds than we can now.  Even if we could travel at 1/2 of light speed, it would still take 8 years to get to the nearest star.  The crew would have very little to do during the voyage.  And, they'd have to carry supplies for the 16-year round trip.  The ship would be enormous -- certainly larger than anything we have ever built.\n\nUntil we can find a way to travel at speeds faster than light, we will not be able to visit other star systems.

As above, the water, atmostpheric pressure, and temperature aren't concducive to human life. But there's another issue: response time. Right now, we have the technology to build a station on Mars. But if something went wrong, it would take us two or three years to get a repairman there!\n\nBecause it takes so long to get there, any settlement on Mars would have to be COMPLETELY self-sustaining, and that's what's really holding us up. (We couldn't even keep the International Space Station going as long as it should have).

It depends on how fast your spaceship can travel and the flight path that you use. The distance to travel 385,000 km \n\nThe first man made object that got to the moon was the Russian Luna 2. It impacted with the Moon and scattered Russian pennants on the Lunar surface. The flight duration was 33.5 hours\n\nThe Apollo missions were a bit slower because the spacecraft first had to reconfigure in earth orbit and then had to brake as they approached the moon. Flight duration to the moon just over 60 hours.\n\nAt this stage there are no spaceships, on earth, capable of getting a human to the moon. So if you start tomorrow with a huge budget you should get there in four or five years.

It takes the earth 365.25 days to complete one revolution of the sun.

Taking the milky-way galaxy to be approx 100 000 ly across, and travelling at a realistic speed of 5 000 km/h, it would take just under 200 000 billion earth years to traverse the galaxy end to end.

You are reffering to the Mars Exploration Rovers.  There is also a probe on it's way to Mars to see if it had any long standing bodies of water.

Manning Mars is not due to any political reasons like the same for moon during cold war.\nEstablishing human civilization in Mars is very necessary for saving homo sapiens, given earth can face disaster at any time.\nSo not only rich, scientists, people from all spheres of life will be required to go to Mars for humanity to prosper there.\nIt seems another 20-25 years will be taken (based on various articles I have read).

Depends on the amount of pollution, The cost of things, house rents, And the friendliness of the people(who knows whether they'll be blood sucking parasites of whether or the next brady bunch), The rate of oxygen masks and tanks... etc.And of course, depends on the space shuttle rates for travelling from mars to earth.

We have been able to navigate and land unmanned craft from the Earth to Mars, however it is a lot different than traveling the 240,000 mile to the moon.  Mars is millions of miles away from Earth.  We just last week launched an unmanned craft to Pluto, it is the fastest traveling spacecraft to date and it is going to travel 36,000 miles an hour and take 9 years to get there.  The amount of dedication and logistics to send a manned spacecraft to Mars sucessfully is probably the biggest question.  I believe when we can get the traveling time down we will see manned missions to Mars, it won't be money that keeps us from going what's another trillion dollars in National Debt amoung friends anyway?

In October, 2005, Mars came within 42-million miles of Earth\n\nIn 2003 it came the closest it has in the last 50,000 years -- 35-million miles\n\nYour weatherman who said it would be as large as the Moon must have been smokin' some wacky tabacky :)

Dave_Stark\n23 seconds ago\n\n\n \n The average distance from Mars to the Sun is 1.52369 astronomical units. One astronomical unit (AU, the average distance from the Sun to the Earth) is 1.49597870E11 meters.\n\nConverting those numbers, then, means that Mars is:\n\n1.52369 * 1.4959787E11 meters = 2.27941E11 meters, or, converting into English units:\n\n141,635,833 miles (on average -- remember that the orbits of the planets around the sun are not circular, but elliptical)

It depends on how fully terraformed Mars was and how risky the flight there would be.  Mars could conceivably be terraformed into a beautiful Earth-like world.  Given safe transportation there, heck yeah I'd consider it, especially if they allowed homesteading.

Yes man will get to mars and probably all the other planets, but no I don't think we will ever live on another planet!

As everybody else noted, the theoretical space journey would take 300 years in earth terms or 298.5 years aboard ship.\n\nThis presents you for some challenges in your story-in-progress as you would need:\n\na) a long-lived character or characters like Robert Heinlein's Lazarus Long; or\n\nb) generations of people born and raised on board ship with new generations trained in running a spaceship; or\n\nc) the passengers kept in hibernation while the crew is manned by androids and advanced computers.
