Average journey time for a Martian probe is about 8 months.
The first spacecraft to land successfully on Mars was Viking 1 in 1975
NASA's Viking 1 and Viking 2 landed on Mars in 1976.
The first NASA space craft to mars set off on August 2007 and they arrived in may 2008
Not yet, only probes have. In the future, NASA are hoping to reach Mars.
Mars, the planet, was first travelled to in 1965 by Mariner 4 (a spacecraft) by the country USA from NASA.
the Mariner 4 launched in 1964 by NASA
The New Horizons spacecraft. It will reach Pluto July 14th 2015.
NASA's Pathfinder landed on Mars on July 4, 1997.
In 2007, NASA launched the Phoenix spacecraft on its way to Mars.
Dear Wiki Questioner, The first spacecraft that visited the planet Mars was the "Mariner 4". It was launched by NASA in 1964 and simply flew past Mars, taking pictures and gathering information as it passed! The first spacecraft to LAND ON Mars were the "Mars 2" and "Mars 3" probes launched by the USSR in 1971. Unfortunately, both of these probes stopped functioning not long after landing on Mars. NASA's "Viking 1" lander was the first spacecraft to land on Mars and function for an extended period of time (6 years in fact).

How long it takes a spacecraft to reach Mars depends on the changing distances between Mars and Earth as they orbit the sun, and other factors. Trips are usually planned for when Mars will be closest to Earth; the shortest is about three months. None of NASA's Space Shuttle fleet are capable of making the trip, and the remaining shuttles are due to be retired.
