The First Aircraft that ever visited the planet is the dumbest question, Don't you know how to specify questions fool?
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).

The spacecraft that landed on Mars in the 1970s was the Viking 1 Lander. It was the first spacecraft to have landed on Mars on July 20, 1976.
One of the spacecraft that has visited Mars is the Mars Curiosity Rover. Launched in 2011 by NASA, its main mission is to explore and assess the Martian climate and geology, and investigate whether Mars could have ever supported microbial life.
Voyager 2 is the only spacecraft to have currently visited both.
Luna 2 and Ranger 4 both smashed into it while Apollo 11 was the first to land with people.
It was Mars 2, from the Soviet Mars Lander Program.
The first spacecraft to visit Mars was Mariner 4. It was launched in 1964 and conducted a flyby of Mars in 1965, sending back the first close-up images of the planet's surface.
