As of yet, there have been no manned Mars spacecraft at all.
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.
The first manned spacecraft to orbit the moon was the Apollo 8 spacecraft.
There are currently no manned missions planned to Mars.

yes,possible for a manned mission to Mars by 2023
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.
Every planet except Pluto has been explored by spacecraft.
The Mariner spacecraft landed on the planet Mars, and the Apollo spacecraft landed on the moon.
Manned spacecraft are very useful because it is easier to see and do things first hand than relying on only readouts from machines and senors.
