Mariner 4 (USA) was the first successful fly by mission, which was launched in 1964. Mariner 9 (USA) was the first probe to orbit another planet (Mars) when it entered into orbit around Mars on November 14, 1971. Mars 2 & 3(USSR) were the first probes to "land" on Mars - probably crashed in 1971 Viking 1 & 2 (USA) were the first probes to successfully land in 1976. See related link for more information.
May 19 - Mars probe program: Mars 2 is launched by the Soviet Union.May 30 - Mariner program: Mariner 9 is launched toward Mars.Nov 13 - Mariner program: Mariner 9 becomes the first spacecraft to enter Mars orbit successfully.
Mars has constantly been visited by spacecrafts. The first spacecraft to visit Mars was the Mariner 4. After that Mars has been visited by numerous spacecrafts like: Mars Pathfinder, Mars Global Surveyor, Mars Odyssey, Mars Express and the Mars 2 which was the first spacecraft to land on Mars.
Numerous spacecraft have been sent to orbit various planets in our solar system. Notable examples include NASA's Voyager 1 and 2, which provided invaluable data about the outer planets, and the Mars Reconnaissance Orbiter, which has been studying Mars since 2006. The Juno spacecraft is currently in orbit around Jupiter, collecting data about its atmosphere and magnetic field. Each of these missions has significantly advanced our understanding of these celestial bodies.
The mariner spacecraft explored Mercury, Mars, and Venus. The first successful space probe and first spacecraft visit to a planet was Mariner 2.
NASA's Viking 1 and Viking 2 landed on Mars in 1976.
Mars had a spacecraft land on it in 1976. NASA's Viking 1 lander successfully landed on Mars on July 20, 1976, followed by its companion, Viking 2, a few weeks later. This marked the first successful landing of a spacecraft on Mars.

As usual, that depends how fast you go. In general, you can divide distance by speed. However, in this case it is a bit more complicated; with current technology, the spacecraft won't go in a straight line. Rather, it will use the speed of Earth, and speed up a bit more, to go into an elliptical orbit around the Sun, which touches both Earth's and Mars's orbits. Half of such an orbit takes about 9 months. Of course, it is possible that in the future, improvements to rocket technology - perhaps better ion drives - manage to go in a more direct route, and to get there faster.
The first object to land on the surface of Mars was the Soviet spacecraft Mars 3, which successfully landed on December 2, 1971.
