known by my knowledge it is mars 2 c'OS mars 1 did not have successful landing both of them are probes of the Soviet Union
First ever satellite to land on the planet Mars was a Russian probe called Mars 2. Albeit it did not land but crashed. The first successful probe to land on Mars was Mars 3 sent by the Russians, however the probe was operational for 15 minutes after landing on Mars. The first American probe to land on Mars was the Viking 1 on the 20th of July 1976.
The first probe to land on Mars was called, the Hubble space craft.
No one's landed on Mars yet. The Soviet Union sent out a probe however, with no one on it. Mars 2 - The first probe that we know of by the Soviet Union to "land" on Mars, the others losing the signals. Mars 2 crash landed. Mars 3 - The first successful soft landing on Mars. Signals were lost 90 seconds after landing. (1971) Mars 5 - First fully successful Soviet Union Mars mission, orbiting Mars. Returned images of Martian surface. (1974) Mars 6 - Landing fail in 1974, crashed into Mars. Others either completely missed it, we lost the signal, or they tried to go to one of Mars' moons (Phobos 1 and 2)
The US and the Soviet Union made several failed attempts to launch a spacecraft to Mars. The Soviet's Mars 1 was the first spacecraft successfully placed on a course toward Mars. It was supposed to do a fly-by. Contact with it was lost while on the way -- it may have passed near the planet. The US spacecraft Mariner 4 completed the first confirmed Mars fly-by on July 14, 1965

The Soviet unmanned spacecraft Luna 9 was the first man-made probe to make a soft landing on the moon on February 3rd, 1966.

1897, 25th June
The Viking 1 lander is generally regarded as the first major probe that has landed on Mars. It landed in 1976. It was the first man made object to land on the surface of Mars.
MARS
The first rovers sent to Mars were the Russian Rovers,Mars 2 and Mars 3. But, Mars 2 crash-landed on the planet and Mars 3 ceased transmissions 20 seconds after landing. Mariner 4 was the first succesfully landed probe.
A space probe is a scientific space exploration mission in which a robotic spacecraft leaves the gravity well of Earth and gathers information about other bodies. So a satellite is also a sapce probe. There are many such probes. The first probe was Mars1 Mars2 was the first probe to actually land on Mars. The other probes that have landed on Mars are Mars3, Mars6, Viking1, Viking2, Pathfinder, Spirit, Opportunity, Phoenix. Check the related link for a full list
