It is estimated that it would take at least three months to send human beings to land on Mars. The travel time depends on where Earth and Mars are in their orbits around the Sun.
Time is of essence. The plans made in 2005 were three to nine months depending on when the flight was launched. The plan in 2005 was for three crew members. One was a Captain in the US Air force as the pilot. He was a graduate of Georgia Tech. Crew member No. 2 was a Russian Cosmonaut, No. 3 A high tech president of a start up company that designed much of the software required for the flight. Funding issues have delayed these plans as well as political issues.

They used to speak of a manned spacecraft going to Mars taking about six months for the journey there, which is about 4,400 hours.
No. So far, there's been no manned travels to Mars
to get living on it
Scientists discuss manned missions to Mars because it would be much easier to send humans to Mars because the conditions on Mars are much less extreme than those on Venus. For example, surface temperatures on Mars range between -125ºC to 35ºC while those on Venus range between 450ºC to 475ºC.

The main difference is that a manned Mars mission is a great deal longer.
We have sent rovers to Mars but there have been no manned missions.
There are currently no manned missions planned to Mars.
As of yet, there have been no manned Mars spacecraft at all.
yes,possible for a manned mission to Mars by 2023
What we need now is a volunteer for our manned mission to Mars. They courageously manned the forward cannons.
A good thesis statement for a research essay titled, "Is it worth the risk and expense to attempt a manned mission to Mars", could be, "The knowledge and strategic advantage of a manned mission to Mars far outweighs the cost and risks".
They used to speak of a manned spacecraft going to Mars taking about six months for the journey there, which is about 4,400 hours.
Estimates vary. Several tens of billions at the most conservative. We do not have the technology at present for a manned mission to Mars.
the problem is getting home
There have been several unmanned spacecraft that have landed on mars (look at http://en.wikipedia.org/wiki/Exploration_of_Mars), but as yet, no manned missions. several space agencies have projected possible manned attempts in the 2030s, (http://en.wikipedia.org/wiki/Manned_mission_to_Mars), but as yet, no formal plans have been decided on.
