did the first one land on the planet or was it just a fly by?
A flyby mode
Introduction
Mariner 4 (together with Mariner 3 known as Mariner-Mars 1964) was the fourth in a series of spacecraft intended for planetary exploration in a flyby mode.
what is the location of mars in the solar system Mars is the fourth planet from the Sun is it known by any other names? Yes, "Red Planet" in English are there any volcanoes there? Yes, Olympus Mons who named it? Named after observations made by Mariner 9 what was that? From Nix Olympica; a volcano. Astronomers adopted the name "Olympus Mons" for the albedo feature known as Nix Olympica was that a spaceship that made the observations? It was a robotic space probe have any other space probes landed on the planet discussed above? Yes, "Mariner 4", "Viking 1", etc
It was just a fly by. Flyby. It was the first successful flyby.

Mariner 4 [SEP] Introduction
Mariner 4 (together with Mariner 3 known as Mariner-Mars 1964) was the fourth in a series of spacecraft intended for planetary exploration in a flyby mode. It was designed to conduct closeup scientific observations of Mars and to transmit these observations to Earth. Launched on November 28, 1964, Mariner 4 performed the first successful flyby of the planet Mars, returning the first close-up pictures of the Martian surface. It captured the first images of another planet ever returned from deep space; their depiction of a cratered, seemingly dead world largely changed the scientific community's view of life on Mars. Other mission objectives were to perform field and particle measurements in interplanetary space in the vicinity of Mars and to provide experience in and knowledge of the engineering capabilities for interplanetary flights of long duration.
