The Mariner 10 probe studied the planet Mercury, which has a crater-pitted surface due to impacts from asteroids and comets over billions of years.

Mariner 2 flew past the planet Venus in 1962, becoming the first spacecraft to successfully encounter another planet. It provided valuable information about Venus's atmosphere and surface temperature.
Mariner 9 was sent out by NASA to orbit Mars and study the planet's surface, atmosphere, and climate. It was the first spacecraft to orbit another planet and provided valuable data on Mars, including detailed images of the surface that revealed features like volcanoes and valleys.
That statement is incorrect. Mariner 2 was the first spacecraft to successfully fly by and study another planet, Venus, not scan. It provided valuable data on Venus' atmosphere and surface temperature.
Mercury was studied by the Mariner 10 Probe and has a crater pitted surface.

Mariner 9 was sent out by NASA to orbit Mars and study the planet's surface, atmosphere, and climate. It was the first spacecraft to orbit another planet and provided valuable data on Mars, including detailed images of the surface that revealed features like volcanoes and valleys.
Mariner 9 took on that spacecraft's mission of mapping 70 percent of the Martian surface in addition to its own objective of studying changes over time in the Martian atmosphere and surface.
