While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the early 20th century that allowed physical space exploration to become a reality.
Common rationales for exploring space include advancing scientific research, uniting different nations, ensuring the future survival of humanity and developing military and strategic advantages against other countries.

Venus was the first target of interplanetary flyby and lander missions. Despite having one of the most hostile surface environments in the Solar System, it has had more landers sent to it from the Soviet Union than any other planet in the Solar System. The first successful Venus flyby was the American Mariner 2 spacecraft, which flew past Venus in 1962.

Dozens of robotic spacecraft, including orbiters, landers, and rovers, have been launched toward Mars since the 1960s.
These missions were aimed at gathering data about current conditions and answering questions about the history of Mars.
The questions raised by the scientific community are expected to not only give a better appreciation of the red planet but also yield further insight into the past, and possible future, of Earth.

The exploration of Neptune began with the 25 August 1989 Voyager 2 flyby.
It discovered 900 complete rings and additional partial ring \'arcs\' around Neptune.
In addition to examining Neptune's three previously known moons, Voyager 2 also discovered five previously unknown moons, one of which, Proteus, proved to be the last largest moon in the system.
Data from Voyager 2 supported the view that Neptune's largest moon, Triton, is a captured Kuiper belt object.

Pluto continues to be of great interest, despite its reclassification as the lead and nearest member of a new and growing class of distant icy bodies of intermediate size.
It is also the first member of the important subclass, defined by orbit and known as \'plutinos\'.
