The first spacecraft to send back data and images from other planets were the Mariner missions in the 1960s and 1970s. Mariner 4 was the first to capture close-up images of Mars in 1965, followed by Mariner 9 orbiting Mars in 1971.
Depends on whether you say Pluto is a planet or not. If you say it isn't, then there are no planets that haven't been visited by a spacecraft. If you say it is, then there is one that hasn't been visited yet, but one is on the way.
The spacecraft that took 22 close-up pictures of Mars in 1965 was called Mariner 4. It was the first spacecraft to successfully fly by Mars and capture close-up images of the planet's surface.
the first spacecraft to explore mars is the mariner 4
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.
The mariner spacecraft explored Mercury, Mars, and Venus. The first successful space probe and first spacecraft visit to a planet was Mariner 2.
The mariner is a space probe that was sent to space to expolre mostly Venus but also explored other planets.

I believe it was part of the Mariner series of satellites
The Mariner spacecraft were unmanned at launch.

The Mariner 2 spacecraft inspected Venus in late 1962.
Mariner 9
The Mariner spacecraft landed on the planet Mars, and the Apollo spacecraft landed on the moon.
